aprepitant and Postoperative-Nausea-and-Vomiting

Postoperative nausea and vomiting (PONV) is one of the common adverse reactions after surgery. Recent randomized controlled trials (RCTs) investigating antiemetic drugs suggest that aprepitant has the strongest antiemetic effect of any single drug. This meta-analysis aimed to explore the efficacy of aprepitant for preventing PONV based on the existing literature.. To identify RCTs investigating the use of aprepitant for PONV prevention, we searched PubMed, Embase, and Cochrane Library databases for articles published prior to March 20, 2022. Seventeen RCTs were identified, with 3299 patients, meeting the inclusion criteria. PONV incidence, complete response, 80 mg aprepitant combined with dexamethasone and ondansetron, vomiting, nausea, and analgesic dose-response were the main outcomes measured.. Compared with the control group, PONV incidence was significantly reduced among those receiving aprepitant (odds ratio [OR]: 0.34; 95% confidence interval [CI]: 0.26, 0.44; P < .0001), with a more complete response (OR: 1.35; 95% CI: 1.14, 1.59; P = .0004). Supplementation of 80 mg aprepitant in combination with dexamethasone and ondansetron substantially improved the effects of PONV (OR: 0.36; 95% CI: 0.16, 0.82; P = .01). Further, administration of 80 mg aprepitant was better at preventing vomiting than nausea (OR: 8.6; 95% CI: 3.84, 19. 29; P < .00001). No statistically significant difference between the dose-response of analgesics was identified (mean difference: -1.09; 95% CI: -6.48, 4.30; P = .69). The risk of bias was assessed independently by paired evaluators.. Aprepitant effectively reduces the incidence of PONV; however, the effects of postoperative analgesia require further exploration.

Postoperative nausea and vomiting (PONV) afflict approximately 30% of patients overall and up to 80% of high-risk patients after surgery. Optimal pharmacological prophylaxis of PONV is challenging as it necessitates the consideration of PONV risk, drug efficacy, and potential adverse effects. Despite significant advances in our understanding of the pathophysiology and risk factors of PONV, its incidence has remained largely unchanged. Newer antiemetics have been introduced that may have improved safety profiles, longer duration of action, and better efficacy. This review aims to summarize the recent developments pertaining to these new agents and their potential application toward the management of PONV.

Postoperative nausea and vomiting (PONV) is an important clinical problem. Aprepitant is a relatively new agent for this condition which may be superior to other treatment. A systematic review was performed after searching a number of medical databases for controlled trials comparing aprepitant with conventional antiemetics published up to 25 April 2015 using the following keywords: 'Aprepitant for PONV', 'Aprepitant versus 5-HT3 antagonists' and 'NK-1 versus 5-HT3 for PONV'. The primary outcome for the pooled analysis was efficacy of aprepitant in preventing vomiting on postoperative day (POD) 1 and 2. 172 potentially relevant papers were identified of which 23 had suitable data. For the primary outcome, 14 papers had relevant data. On POD1, 227/2341 patients (9.7%) patients randomised to aprepitant had a vomiting episode compared with 496/2267 (21.9%) controls. On POD2, the rate of vomiting among patients receiving aprepitant was 6.8% compared with 12.8% for controls. The OR for vomiting compared with controls was 0.48 (95% CI 0.34 to 0.67) on POD1 and 0.54 (95% CI 0.40 to 0.72) on POD2. Aprepitant also demonstrated a better profile with a lower need for rescue antiemetic and a higher complete response. Efficacy for vomiting prevention was demonstrated for 40 mg, 80 mg and 125 mg without major adverse effects. For vomiting comparison there was significant unexplainable heterogeneity (67.9% and 71.5% for POD1 and POD2, respectively). We conclude that (1) aprepitant reduces the incidence of vomiting on both POD1 and POD2, but there is an unexplained heterogeneity which lowers the strength of the evidence; (2) complete freedom from PONV on POD1 is highest for aprepitant with minimum need for rescue; and (3) oral aprepitant (80 mg) provides an effective and safe sustained antivomiting effect.

Newly developed neurokinin-1 receptor (NK-1R) antagonists have been recently tried in the prevention of postoperative nausea and vomiting (PONV). This systematic review and meta-analysis was conducted to explore whether NK-1R antagonists were effective in preventing PONV.The PRISMA statement guidelines were followed. Randomized clinical trials (RCTs) that tested the preventive effects of NK-1R antagonists on PONV were identified by searching EMBASE, CINAHL, PubMed, and the Cochrane Library databases followed by screening. Data extraction was performed using a predefined form and trial quality was assessed using a modified Jadad scale. The primary outcome measure was the incidence of PONV. Meta-analysis was performed for studies using similar interventions. Network meta-analysis (NMA) was conducted to compare the anti-vomiting effects of placebo, ondansetron, and aprepitant at different doses.Fourteen RCTs were included. Meta-analysis found that 80 mg of aprepitant could reduce the incidences of nausea (3 RCTs with 224 patients, pooled risk ratio (RR) = 0.60, 95% confidence interval (CI) = 0.47 to 0.75), and vomiting (3 RCTs with 224 patients, pooled RR = 0.13, 95% CI = 0.04 to 0.37) compared with placebo. Neither 40 mg (3 RCTs with 1171 patients, RR = 0.47, 95% CI = 0.37 to 0.60) nor 125 mg (2 RCTs with 1058 patients, RR = 0.32, 95% CI = 0.13 to 0.78) of aprepitant showed superiority over 4 mg of ondansetron in preventing postoperative vomiting. NMA did not find a dose-dependent effect of aprepitant on preventing postoperative vomiting.Limited data suggested that NK-1R antagonists, especially aprepitant were effective in preventing PONV compared with placebo. More large-sampled high-quality RCTs are needed.

Postoperative nausea and vomiting (PONV) affects as many as 30% of surgical patients. Aprepitant, an antagonist of the neurokinin-1 receptor with a 40% half-life, may be effective for prophylaxis for PONV. This review describes the evidence of adding aprepitant to antiemetic therapy for PONV prophylaxis.. A literature search was conducted to answer the population-intervention-comparison-outcome-time (PICOT) question: In adult patients undergoing general anesthesia (P), does aprepitant (I) decrease PONV (O) postoperatively (T) as compared to patients receiving other antiemetic therapy or a placebo (C)?. Eight randomized controlled trials, one prognostic study, and one post hoc analysis were appraised. Perioperatively, aprepitant decreased the severity and number of episodes of PONV.. Aprepitant appears to be more effective in decreasing the incidence of PONV postoperatively as compared with ondansetron. It is recommended that aprepitant is used to treat patients at risk for PONV and for whom PONV could lead to catastrophic adverse outcomes.

This review will address novel options for the prevention and treatment of postoperative and postdischarge nausea and vomiting (PONV and PDNV) after ambulatory anesthesia. In particular, this paper will review the characteristics of neurokinin-1 receptor antagonists (NK1-RAs) and the new serotonin receptor antagonist (5HT3-RA) palonosetron. Finally, we will discuss strategies for prophylaxis and treatment of PONV and PDNV that address the unique concerns in ambulatory surgery patients.. First, although PONV has previously been recognized to be a problem for inpatients, new research suggests that the incidence of PDNV after ambulatory surgery may be as high as 35%. Second, NK1-RAs, including aprepitant, the first approved member of this family, are significantly more efficacious than any other antiemetic for the prevention of vomiting. They are however not more effective than other interventions for the control of nausea. Third, the next generation of 5HT3-RAs, such as palonosetron, does not affect the QT interval and has a half-life of 40 h that should be advantageous for the prevention of PDNV.. Because of the high incidence of PDNV, a predictive model for PDNV would be helpful to determine appropriate antiemetic interventions for each individual patient. Drugs that may be particularly favorable are the novel NK1-RA aprepitant and the next generation 5HT3-RA palonosetron.

During the last two decades there have been considerable achievements regarding the management of postoperative nausea and vomiting (PONV). Due to the importance of these symptoms in the aim to streamline clinical processes and to improve patient satisfaction, the debate on the best strategies and also research that focuses on PONV continues. This review summarises the recent developments with respect to the management of PONV. Following a brief review on what is already known on the risk assessment, prevention and treatment of PONV, newer trends in the pharmacological prevention (dexamethasone, neurokinin-1 antagonists, multimodal prevention) will be discussed as well as new insights regarding the value of algorithms for the prevention of PONV. Further, pharmacogenetically based algorithms (according to the metaboliser status) as well as new treatment strategies (dexamethasone, multimodal treatment) will be covered. No drug so far can achieve a reduction of PONV of more than one third. Furthermore, all clinical studies consistently demonstrated that a combination treatment has a simple additive effect without any relevant interaction between different drugs or classes of drugs. The relative reduction of approximately 30% can also be expected from dexamethasone and it is likely that the substances presently in development and in an early clinical use (e.g., neurokinin-1 antagonists) will not represent the new panacea. However, they will probably replenish the existing antiemetic portfolio to better cope with high risk patients. Stratified prevention using pharmacogenetic knowledge is still in the early stages. Algorithms need to be customized to the local settings in order to prove efficient. Treatment remains a most important pillar and there is evidence that the principles of combining antiemetics to prolong effects and improve protection can be similarly applied to treatment. Recent developments in the area of PONV are more related to implementing the already existing evidence than based on the introduction of new molecules. New molecules replenish the pharmacological antiemetic portfolio, which is needed due to the limited efficacy of any single agent available so far. The new neurokinin-1 receptor antagonist, aprepitant, and the long lasting 5-HT(3) receptor antagonist palonosetron are the latest developments in this context. Treatment is most important and can also be regarded as a secondary prevention. Due to limited efficacy of single treatment in

To evaluate the addition of a fourth antiemetic intervention in patients at high risk for postoperative nausea and vomiting (PONV).. High-risk patients (Apfel score 3 or 4) scheduled for unilateral mastectomy were randomly allocated in one of two groups, oral aprepitant (oral aprepitant 80 mg, intravenous dexamethasone 8 mg, and palonosetron 0.075 mg) and oral placebo (oral placebo, intravenous dexamethasone 4 mg, and palonosetron 0.075 mg). Patients and caregivers were blinded to the group assignments. The primary efficacy endpoints included the incidence of nausea and vomiting, and the secondary endpoints included use of rescue antiemetics during a 48-hour postoperative period. ClinicalTrials.gov: NCT02431286.. One hundred patients were enrolled in this study and 91 were analyzed, 48 in group A and 43 in group P. No patient presented with nausea or vomiting in the first 2 hours after surgery. From the 2nd to the 6th hour, the incidence of PONV was 8.33% in group A and 9.30% in group P. In the first 24 hours, the incidence of PONV was 27.08% in the group A and 20.93% in group P. From the 24th to the 48th hour, the incidence of PONV was 8.33% in group A and 13.95% in group P. There were no statistically significant differences in PONV between groups.. The addition of aprepitant as a third antiemetic resulted in no significant reduction in the incidence of PONV in this population. However, the incidence of PONV was reduced in relation to the general population.

This multicenter, randomized, partially-blinded phase IIb study evaluated the pharmacokinetics (PK)/pharmacodynamics, safety, and tolerability of aprepitant in pediatric subjects for the prevention of postoperative nausea and vomiting (PONV).. Subjects aged birth to 17 years scheduled to undergo surgery and receive general anesthesia with ≥1 risk factor for PONV were randomly assigned to 1 of 3 aprepitant dose regimens (a single oral dose of aprepitant equivalent to adult doses of 10 mg, 40 mg, or 125 mg), or a control regimen of ondansetron before anesthesia. Assessments included PK, safety, and exploratory efficacy (complete response [CR; no emesis, retching, or dry heaves and no rescue therapy within 0-24 h following surgery] and no vomiting [NV; no emesis, retching, or dry heaves within 0-24 h following surgery]).. Of 220 randomized and treated subjects, 119 receiving a single aprepitant dose were sampled for PK analysis and had evaluable aprepitant plasma concentrations. A dose-dependent relationship in exposure (AUC0-8 h and Cmax) was observed. Aprepitant was generally well tolerated, and the CR and NV rates were high (>80%) across treatment groups.. PK, safety, and preliminary efficacy analyses support further clinical evaluation of aprepitant for PONV prophylaxis in pediatric patients. CLINICALTRIALS..

Post-operative nausea and vomiting (PONV) is one of the most important causes of patient discomfort after laparoscopic surgeries despite the use of a multimodal pharmacological approach. This study assessed whether the addition of aprepitant to a multimodal regimen would further decrease the incidence of PONV in high-risk patients.. Apfel-score three or four patients, scheduled for laparoscopic procedures to treat abdominal or pelvic cancer, were randomized to receive oral starch (control group) or 80 mg of oral aprepitant (treatment group) before induction of anaesthesia in a double-blind study. All patients received 4-8 mg of intravenous dexamethasone (at induction) and 4-8 mg of ondansetron (at the end) and a standardized total intravenous anaesthesia (TIVA) technique combined with neuraxial blockade. PONV was defined as any episode of nausea, vomiting or retching in the first 24 h after anaesthesia.. Sixty-six patients completed the study. Vomiting occurred in 13/32 (40.6%) patients in the control group and in 1/34 (2.9%) patients in the treatment group (P = 0.0002, 95%CI: 18-54%) in the first 24 h after anaesthesia. Severe nausea occurred in two (6.3%) patients, and severe vomiting occurred in four (12.5%) patients in the control group. One patient presented with severe vomiting in the treatment group in the first 24 post-operative hours.. Eighty milligrams of aprepitant added to a three-drug multimodal prophylaxis strategy can bring benefits to a high-risk population by reducing PONV episodes and rescue antiemetic requirements. This study was registered in the ClinicalTrials.gov (NCT 02357693) database.

The aim of this study was to evaluate aprepitant in combination with palonosetron as compared to palonosetron alone for the prevention of postoperative nausea and vomiting (PONV) in female patients receiving fentanyl- based intravenous patient-controlled analgesia (IV-PCA).. In this randomized single-blinded study, 100 female patients scheduled for elective surgery under general anesthesia were randomized to two groups: Group AP (80 mg aprepitant plus 0.075 mg palonosetron, n = 50) and Group P (0.075 mg palonosetron, n = 50). The patients in group AP received 80 mg aprepitant per oral 1-3 h before surgery, while all patients received 0.075 mg palonosetron after induction of standardized anesthesia. All patients had postoperative access to fentanyl-based IV-PCA. The incidence of nausea and vomiting, use of rescue medication, and severity of nausea were evaluated at 6 and 24 h after surgery.. The incidence of nausea (54%) and vomiting (2%) in group AP did not differ significantly from that in group P (48% and 14%, respectively) during the first 24 h after surgery (P > 0.05). Patient requirements for rescue medication in group AP (29%) were similar to those in group P (32%) at 24 h after surgery (P > 0.05). There was no difference between the groups in severity of nausea during the first 24 h after surgery (P > 0.05).. Aprepitant combined with palonosetron did not reduce the incidence of PONV as compared to palonosetron alone within 24 h of surgery in women receiving fentanyl-based IV-PCA.

Chemotherapy-induced nausea and vomiting (CINV) is a significant side effect in multiple myeloma (MM) patients receiving high-dose melphalan treatment followed by autologous stem cell transplantation (ASCT). We evaluated the efficacy and safety of a triple antiemetic combination of palonosetron, aprepitant, and low-dose dexamethasone in 24 MM patients who received melphalan conditioning (100 mg/m

Ondansetron, a 5-HT3 receptor antagonist, and aprepitant, a neurokinin-1 receptor antagonist, block the emetic effect of serotonin and neurokinin, respectively. Aprepitant combined with ondansetron can be more effective for preventing emesis in patients at high risk of postoperative nausea and vomiting (PONV).. To investigate the prophylactic effect of combining aprepitant with ondansetron compared with ondansetron alone on PONV in patients with fentanyl-based patient-controlled analgesia (PCA) after laparoscopic gynaecological surgery.. Single-centre, double-blinded randomised controlled trial.. A major university hospital in Seoul, Korea, between July 2012 and April 2013.. One hundred and twenty-five female patients (American Society of Anesthesiologists' physical status 1 or 2) with fentanyl-based intravenous PCA after gynaecological laparoscopy were recruited to the study, and 110 completed the protocol.. Oral aprepitant 80 mg or placebo was given 1 h before anaesthesia. In all patients, ondansetron 4 mg was administered intravenously at the end of surgery and 12 mg was added to the PCA solution.. The primary outcome measure was complete response (no PONV and no rescue antiemetics) up to 48 h postoperatively.. There was no difference in the proportion of complete responses to 48 h between the groups (P = 0.05), but in the post-anaesthesia care unit and up to 24 h postoperatively, the proportion was significantly higher in the aprepitant and ondansetron group than in the ondansetron only group (76 vs. 50%, P = 0.004 and 38 vs. 16%, P = 0.011, respectively). In the aprepitant and ondansetron group, the time to first PONV was delayed (P = 0.014) and the incidence of nausea up to 24 h postoperatively was lower (P = 0.014). However, there were no differences in the incidences of retching or vomiting, the severity of nausea, use of rescue antiemetics or the incidence of side-effects.. Aprepitant 80 mg orally with ondansetron is effective in suppressing early PONV up to 24 h postoperatively and delays the time to first PONV in patients with fentanyl-based intravenous PCA after gynaecological laparoscopy. However, the combination prophylaxis with aprepitant and ondansetron failed to reach the predefined primary study outcome when compared with ondansetron alone..

We compared the antiemetic efficacy of aprepitant plus palonosetron versus aprepitant plus ramosetron in patients after laparoscopic cholecystectomy. A total of 88, nonsmoking, female patients undergoing laparoscopic cholecystectomy were randomly allocated to 2 groups of 44 each who received palonosetron 0.075 mg (aprepitant plus palonosetron group) and ramosetron 0.3 mg (aprepitant plus ramosetron group) after induction of anesthesia. All patients received aprepitant 80 mg 2 hours before surgery. The incidence of postoperative nausea and vomiting (PONV), use of rescue antiemetic, pain severity, and any side effects were assessed for 24 hours after surgery. The incidence of PONV and use of rescue antiemetic were less in aprepitant plus palonosetron group than in aprepitant plus ramosetron group for 24 hours after surgery (P<0.05, respectively). There was no difference in pain severity and side effects including headache and drowsiness. Aprepitant plus palonosetron significantly prevents PONV, compared with aprepitant plus ramosetron in patients at high risk for PONV after laparoscopic cholecystectomy.

Postoperative opioid analgesia increases the incidence of postoperative nausea and vomiting (PONV). We investigated whether a combination of the neurokinin-1 antagonist aprepitant and dexamethasone decreases PONV incidence compared with dexamethasone alone in high-risk patients receiving continuous epidural fentanyl.. Sixty nonsmoking female patients scheduled for elective knee osteoarthritis surgery were randomly allocated to receive oral aprepitant 80 mg (aprepitant+dexamethasone group, N.=30) 2 h before anesthesia induction or no oral aprepitant (dexamethasone group, N.=30). All patients received intravenous dexamethasone 8 mg immediately before anesthesia induction. Anesthesia was maintained with remifentanil and sevoflurane. Continuous infusion of epidural analgesia, including fentanyl, was provided during and after surgery. We assessed complete response (no PONV and no rescue antiemetic use), incidence of nausea and vomiting, nausea severity scale, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24 h after surgery.. The cumulative incidence of vomiting at 24 h was 3% in the aprepitant+dexamethasone group and 27% in the dexamethasone group (P=0.011). The incidence and frequency of vomiting in the late postoperative period was also significantly lower in the aprepitant+dexamethasone group than in the dexamethasone group. However, there were no significant group differences in the proportion of patients who experienced a complete response, the incidence and severity of nausea, and rescue antiemetic use at 24 h.. The combination of aprepitant and dexamethasone was more effective in preventing postoperative vomiting compared with dexamethasone alone in patients at high-risk of PONV from continuous epidural fentanyl analgesia.

Postoperative nausea and vomiting is a major cause of patient dissatisfaction towards surgery. For bariatric surgery, increased vomiting/retching is detrimental to surgical anastomosis. The present study evaluated the efficacy of aprepitant (neurokinin-1 inhibitor) as a prophylactic antiemetic in morbidly obese patients for laparoscopic bariatric surgery.. After institutional review board approval, 125 morbidly obese patients were recruited into this double-blind placebo-controlled trial. On random division, the patients received a tablet of aprepitant (80 mg) in group A, or a similar-appearing placebo in group P, an hour prior to surgery. All patients received intravenous ondansetron (4 mg) intraoperatively. Postoperatively, the patients were evaluated for nausea and vomiting by a blinded evaluator at 30 min, 1, 2, 6, 24, 48, and 72 h.. Both groups were evenly distributed for age, body mass index, type, and length of surgery. Cumulative incidence of vomiting at 72 h was significantly lower in group A (3%) compared to group P (15%; p = 0.021). Odds ratio for vomiting in group P compared to group A was 5.47 times. On Kaplan-Meier plot, time to first vomiting was also significantly delayed in group A (p = 0.019). A higher number of patients showed complete absence of nausea or vomiting in group A compared to group P (42.18 vs. 36.67%). On the other hand, nausea scores were unaffected by aprepitant, and no significant difference between groups was found at any of the measured time points.. In morbidly obese patients undergoing laparoscopic bariatric surgery, addition of aprepitant to ondansetron can significantly delay vomiting episodes simultaneously lowering the incidence of postoperative vomiting.

Postoperative nausea and vomiting (PONV) is one of the most common postsurgical complications. Palonosetron, a 5-hydroxytryptamine receptor antagonist, is effective for PONV prevention. Herein, we compared palonosetron and aprepitant (a neurokinin-1 receptor antagonist) for PONV prevention in patients indicated for laparoscopic gynaecologic surgery.. Ninety-three patients who were scheduled to undergo laparoscopic gynaecologic surgery under general anaesthesia were assigned to receive either a single intravenous injection of 0.075-mg palonosetron or 40-mg oral aprepitant in a double-blind randomised trial. The primary efficacy end points included complete response (visual analogue scale [VAS] nausea score <4 and no use of rescue therapy) 0-48 h after surgery. Nausea severity (0-10) and use of rescue therapy were monitored for 0-48 h. The secondary efficacy end points were the effect of aprepitant quantified using a 10-point VAS for pain, consumption of intravenous patient-controlled analgesia, and use of rescue analgesics.. Aprepitant was non-inferior to palonosetron in terms of complete response 0-48 hours after surgery (74% vs. 77%). At 0 and 2 h after administration, the nausea severity with 40-mg aprepitant was significantly lesser than that with 0.075-mg palonosetron (P < 0.05). At 6 and 24 h after administration, fentanyl consumption with 40-mg aprepitant was significantly lower than that with 0.075-mg palonosetron. Greater amounts of rescue analgesics were required in the aprepitant group.. Palonosetron and aprepitant were both effective for PONV prevention in the patients indicated for laparoscopic gynaecologic surgery. The drugs can be used in combination for multimodal therapy because they bind to different receptors. More research is needed to evaluate the effects of aprepitant on pain management in humans.

Uncontrolled delayed nausea and vomiting remains a problem after high-dose preparative regimens used for autologous and allogeneic hematopoietic stem cell transplants. Recently, aprepitant was approved for highly and moderately emetogenic chemotherapy, and, in particular, is effective for decreasing delayed emesis. To evaluate its safety and efficacy in the transplantation setting, we performed a randomized, placebo-controlled, phase 3 trial of aprepitant in combination with ondansetron and dexamethasone in patients treated with ablative preparative regimens. Patients were randomized to receive oral aprepitant or placebo daily with oral ondansetron and dexamethasone during and for 3 days after the completion of the preparative regimen in this prospective randomized, double-blind study. The primary objective was complete response (CR) rate, defined as no emesis with no or mild nausea. Other endpoints included number of emetic episodes, nausea severity assessed using a 100-mm visual analog scale (VAS), the need for rescue antiemetics, and transplantation outcome, including regimen-related toxicity. One hundred eighty-one patients were randomized and 179 patients were eligible for analysis. Overall, CR rates were 81.9% for the aprepitant and 65.8% for the placebo arms (P < .001). Percentages of patients with no emesis all days were 73.3% for aprepitant and 22.5% placebo (P < .001). Mean VAS scores were 16.6 mm aprepitant and 16.9 mm placebo (NS), and there were no differences in the amount of rescue antiemetics used, regimen related toxicity, engraftment, or transplantation outcome. Aprepitant in combination with dexamethasone and ondansetron significantly decreased emesis and significant nausea, whereas not increasing RRT or affecting short-term survival but had no significant impact on the use of PRN antiemetics, or overall VAS nausea scores.

The use of opioids following surgery is associated with a high incidence of postoperative nausea and vomiting (PONV). We conducted a prospective, randomized, double-blind, placebo-controlled study to investigate the effect of orally administered aprepitant, a neurokinin-1 receptor antagonist, for reducing PONV in patients with fentanyl-based, patient-controlled analgesia (PCA) given intravenously after gynecological laparoscopy.. One hundred and twenty female patients (ages 21-60) undergoing laparoscopic hysterectomy were randomly allocated to receive 80 mg (A80 group, n = 40) or 125 mg aprepitant (A125 group, n = 40) or placebo (control group, n = 40) orally 2 h before anesthesia induction. Anesthesia was maintained with isoflurane and remifentanil, and PCA IV using fentanyl and ketorolac were provided for 48 h after surgery. Incidences of nausea, vomiting/retching, and use of rescue antiemetics were recorded at 2, 24, and 48 h after surgery. Complete response was defined as no PONV and no need for rescue treatment.. The incidence of complete response was significantly lower in the A80 and A125 groups than in controls, 56 % and 63 %, vs. 28 %, respectively, P = 0.007 and P = 0.003, respectively, during the first 48 h, and 65 % and 65 % vs. 38 %, respectively, both P = 0.025, during the first 2 h. However, there were no statistically significant differences between A80 and A125 groups in the incidences of complete response and PONV during the study period.. Aprepitant 80 mg orally was effective in lowering the incidence of PONV in the first 48 h after anesthesia in patients receiving fentanyl-based PCA after gynecological laparoscopy.

Postoperative nausea and vomiting is a major challenge in the perioperative setting. The incidence can be as high as 80 percent, and the majority of the symptoms among outpatients occur after discharge. This study evaluated the efficacy of a neurokinin-1 receptor antagonist (aprepitant) in reducing postoperative symptoms for up to 48 hours in patients undergoing outpatient plastic surgery.. A prospective, double-blinded, randomized, two-arm evaluation of 150 ambulatory plastic surgery patients receiving a standardized general anesthetic, including postoperative nausea and vomiting prophylaxis with ondansetron and either aprepitant or placebo, was performed. The main outcome measures were the occurrence of vomiting and the severity of nausea for up to 48 hours postoperatively.. Overall, 9.3 percent of patients who received aprepitant versus 29.7 percent in group B had vomiting, with the majority of vomiting episodes occurring after hospital discharge. The Kaplan-Meier plot of the hazards of vomiting revealed an increased incidence of emesis in patients receiving ondansetron alone compared with the combination of ondansetron and aprepitant (p = 0.006). The incidence of nausea was not significantly different in the two groups. Severity of nausea, however, was significantly higher in those receiving ondansetron alone compared with those receiving ondansetron and aprepitant, as measured by a peak nausea score (p = 0.014) and by multivariate analysis of variance results comparing repeated verbal rating scale scores over 48 hours after surgery (p = 0.024).. In patients undergoing plastic surgery, the addition of aprepitant to ondansetron significantly decreases postoperative vomiting rates and nausea severity for up to 48 hours postoperatively..

Aprepitant blocks the emetic effects of substance P. Scopolamine antagonizes muscarinic type 1 and histamine type 1 receptors. This study compares monotherapy and multimodal therapy by looking at complete response, nausea, vomiting, and rescue medication in patients at high risk for postoperative nausea and vomiting (PONV) treated with oral aprepitant with or without scopolamine.. We enrolled 120 patients in this randomized, double-blind trial. Inclusion criteria were: >18 yr old, ASA I-III, two or more Apfel four-point risk factors, undergoing an elective surgical procedure with a high risk of PONV expected to last at least 60 min. The primary outcome variable was complete response, that is, no emesis and no rescue therapy from 0 to 24 h. The outcomes measured included the incidences of nausea, vomiting, their composite, and the need for rescue medication.. The aprepitant alone and aprepitant with scopolamine did not differ in complete responses (63% vs 57%, P=0.57) or net clinical benefit (26% vs 19%, P=0.38). The number who did not experience PONV and who used rescue medication did not differ. The incidence of PONV in the post-anaesthesia care unit did not differ nor did the use of rescue medications.. This trial evaluating the effectiveness of aprepitant alone and in combination with scopolamine showed no difference between treatment groups. The primary objective, complete response, and secondary objectives, incidences of nausea, vomiting, their composite, and the need for rescue medication, all showed no statistical difference.

The incidence of postoperative nausea and vomiting (PONV) is 50% to 80% after neurosurgery. The common prophylactic treatment for postoperative nausea and vomiting is a triple therapy of droperidol, promethazine and dexamethasone. Newer, more effectives methods of prophylaxis are being investigated. We designed this prospective, double-blind, single-center study to compare the efficacy of ondansetron, a neurokinin-1 antagonist, and aprepitant, as a substitute for droperidol, in the prophylactic treatment of postoperative nausea and vomiting after neurosurgery.. After obtaining institutional review board approval; 176 patients, 18 to 85 years of age with American Society of Anesthesiologists (ASA) classifications I to III, who did not receive antiemetics 24 h before surgery and were expected to undergo general anesthesia for neurosurgery lasting longer than 2 h were included in this study. After meeting the inclusion and exclusion criteria and providing written informed consent, patients were randomly assigned in a 1:1 ratio to one of two treatment groups: aprepitant or ondansetron. The objective of this study was to conduct a randomized, double-blind, double-dummy, parallel-group and single-center trial to compare and evaluate the efficacies of aprepitant versus ondansetron. Patients received oral aprepitant 40 mg OR oral dummy pill within 2 h prior to induction. At induction, a combination of intravenous dexamethasone 10 mg, promethazine 25 mg, and ondansetron 4 mg OR dummy injection was administered. Therefore, all patients received one dummy treatment and three active PONV prophylactic medications: dexamethasone 10 mg, promethazine 25 mg, and either aprepitant 40 mg OR ondansetron 4 mg infusion. The primary outcome measures were the episodes and severity of nausea and vomiting; administration of rescue antiemetic; and opioid consumption for 120 h postoperatively. Standard safety assessments included adverse event reports, physical and laboratory data, awakening time and duration of recovery from anesthesia.. The results of this comparative study could potentially identify an improved treatment regimen that may decrease the incidence and severity of postoperative nausea and vomiting in patients undergoing neurosurgery. Also, this will serve to enhance patient recovery and overall satisfaction of neurosurgical patients in the immediate postoperative period..

Postoperative nausea and vomiting (PONV) occur commonly after craniotomy. In patients receiving prophylaxis with ondansetron and dexamethasone, vomiting occurred in 45% of patients at 48 hours. In addition to causing patient discomfort, the physical act of vomiting may increase intracranial pressure or cerebral intravascular pressure, jeopardizing hemostasis and cerebral perfusion. Aprepitant is a neurokin-1 receptor antagonist with a long duration of action and no sedative side effect. In a large multicenter study in patients undergoing abdominal surgery, aprepitant was significantly more effective than was ondansetron in preventing vomiting at 24 and 48 hours postoperatively. We hypothesized that the combination of aprepitant with dexamethasone will decrease the incidence of postoperative vomiting when compared with the combination of ondansetron and dexamethasone in patients undergoing craniotomy under general anesthesia.. Patients scheduled to undergo craniotomy under general anesthesia were enrolled in this prospective, double-blind, randomized study. Patients were randomized to receive oral aprepitant 40 mg (or matching placebo) 1 to 3 hours before induction of anesthesia or ondansetron 4 mg IV (or placebo) within 30 minutes of the end of surgery. All patients received dexamethasone 10 mg after induction of anesthesia. The anesthetic technique was standardized. Data were collected at regular intervals by blinded personnel for 48 hours after surgery. Statistical analysis was performed using Wilcoxon's ranked sum test and χ(2) test. P < 0.05 was considered statistically significant.. One hundred four patients completed the study. The cumulative incidence of vomiting at 48 hours was 16% in the aprepitant group and 38% in the ondansetron group (P = 0.0149). The incidence of vomiting was also decreased in the aprepitant group at 2 hours (6% vs. 21%, P = 0.0419) and 24 hours (14% vs. 36%, P = 0.0124). From 0 to 48 hours, there was no difference between the aprepitant and ondansetron groups in the incidence of nausea (69% vs. 60%), nausea scores, need for rescue antiemetics (65% vs. 60%), complete response (no PONV and no rescue, 22% vs. 36%), or patient satisfaction with the management of PONV.. The combination of aprepitant and dexamethasone was more effective than was the combination of ondansetron and dexamethasone for prophylaxis against postoperative vomiting in adult patients undergoing craniotomy under general anesthesia. However, there was no difference between the groups in the incidence or severity of nausea, need for rescue antiemetics, or in complete response between the groups.

Post-operative nausea and vomiting (PONV) remains the most frequently reported patient complaint after anesthesia. Aprepitant is the first neurokinin-1(NK1) receptor antagonism available for use as an antiemetic. We investigated whether aprepitant can effectively decrease PONV in patients undergoing laparoscopic gynecological surgery.. Sixty four patients receiving general anesthesia for laparoscopic gynecological surgery were randomly assigned to either receive a preoperative dose of 80 mg aprepitant or no drug. Efficacy was assessed in 2 and 24 hours after surgery. Primary and secondary endpoints were analyzed for the time intervals 0-2 hours (acute phase) and 2-24 hours (delayed phase). Vomiting, nausea, use of rescue anti-emetic, and visual analog scale (VAS) were assessed. Nausea was assessed on a 4-point scale, from 0 to 3.. Sixty patients participated in the study. At acute phase, PONV was present in both control and NK1 group and were 63% and 43% respectively. The severity of nausea was much less in the NK1 group. PONV prevalence at delayed phase was present in control but absent in NK1 group 27% vs. 0%, respectively. The amount of pain medication used by patients in the NK1 group was significantly less for diclofenac and pentazocine suggesting increase pain tolerance.. Neurokinin-1 receptor antagonism effectively lowered PONV increased pain tolerance, and expedited recovery in patients undergoing laparoscopic gynecological surgery.

Antiemetics currently in use are not totally effective. Neurokinin-1 receptor antagonists are a new class of antiemetic that have shown promise for chemotherapy-induced nausea and vomiting. This is the first study evaluating the efficacy and tolerability of the neurokinin-1 receptor antagonist, aprepitant, for the prevention of postoperative nausea and vomiting.. In this multicenter, double-blind trial, we randomly assigned 805 patients receiving general anesthesia for open abdominal surgery to a preoperative dose of aprepitant 40 mg orally, aprepitant 125 mg orally, or ondansetron 4 mg IV. Vomiting, nausea, and use of rescue therapy were assessed over 48 h after surgery. Treatments were compared using logistic regression.. Incidence rates for the primary end point (complete response [no vomiting and no use of rescue] over 0-24 h after surgery, tested for superiority of aprepitant) were not different across groups (45% with aprepitant 40 mg, 43% with aprepitant 125 mg, and 42% with ondansetron). The incidence of no vomiting (0-24 h) was higher with aprepitant 40 mg (90%) and aprepitant 125 mg (95%) versus ondansetron (74%) (P < 0.001 for both comparisons), although between-treatment use of rescue and nausea control was not different. Both aprepitant doses also had higher incidences of no vomiting over 0-48 h (P < 0.001). No statistically significant differences were seen among the side effect profiles of the treatments.. Aprepitant was superior to ondansetron for prevention of vomiting in the first 24 and 48 h, but no significant differences were observed between aprepitant and ondansetron for nausea control, use of rescue, or complete response.

The neurokinin(1) antagonist aprepitant is effective for prevention of chemotherapy-induced nausea and vomiting. We compared aprepitant with ondansetron for prevention of postoperative nausea and vomiting.. Nine hundred and twenty-two patients receiving general anaesthesia for major abdominal surgery were assigned to receive a single preoperative dose of oral aprepitant 40 mg, oral aprepitant 125 mg, or i.v. ondansetron 4 mg in a randomized, double-blind trial. Vomiting episodes, use of rescue therapy, and nausea severity (verbal rating scale) were documented for 48 h after surgery. Primary efficacy endpoints were complete response (no vomiting and no use of rescue therapy) 0-24 h after surgery and no vomiting 0-24 h after surgery. The secondary endpoint was no vomiting 0-48 h after surgery.. Aprepitant at both doses was non-inferior to ondansetron for complete response 0-24 h after surgery (64% for aprepitant 40 mg, 63% for aprepitant 125 mg, and 55% for ondansetron, lower bound of 1-sided 95% CI > 0.65), superior to ondansetron for no vomiting 0-24 h after surgery (84% for aprepitant 40 mg, 86% for aprepitant 125 mg, and 71% for ondansetron; P < 0.001), and superior for no vomiting 0-48 h after surgery (82% for aprepitant, 40 mg, 85% for aprepitant, 125 mg, and 66% for ondansetron; P < 0.001). The distribution of peak nausea scores was lower in both aprepitant groups vs ondansetron (P < 0.05).. Aprepitant was non-inferior to ondansetron in achieving complete response for 24 h after surgery. Aprepitant was significantly more effective than ondansetron for preventing vomiting at 24 and 48 h after surgery, and in reducing nausea severity in the first 48 h after surgery. Aprepitant was generally well tolerated.

Compared with the 5HT(3) antagonist ondansetron, the NK(1) antagonist aprepitant has been shown in two double-blind trials to provide greater protection against postoperative vomiting and comparable or greater control of nausea. Post hoc analyses of pooled data from these trials were performed to more fully characterize the efficacy profile of aprepitant in terms of nausea and use of rescue therapy.. Patients (n = 1599) scheduled for major surgery under general anesthesia (primarily gynecological surgery) were assigned to receive a preoperative dose of aprepitant 40 mg PO, 125 mg PO, or ondansetron 4 mg IV. in two randomized, double-blind, clinical trials.. Post-surgery vomiting episodes, use of rescue therapy, and nausea severity (verbal rating scale).. In the 24 hours after surgery, aprepitant 40 mg was more effective than ondansetron for all five endpoints evaluated: (1) no significant nausea (56.4% vs. 48.1%); (2) no nausea (39.6% vs. 33.1%); (3) no vomiting (86.7% vs. 72.4%); (4) no nausea and no vomiting (38.3% vs. 31.4%); and (5) no nausea, no vomiting, and no use of rescue (37.9% vs. 31.2%) (p < 0.035 for the odds ratio for each comparison). Numerically more patients receiving aprepitant 125 mg also achieved these endpoints compared with ondansetron.. These post hoc analyses confirm the favorable efficacy profile of aprepitant for the prevention of post operative nausea and vomiting.

Postoperative nausea and vomiting (PONV) is one of the most common adverse effects of anesthesia and surgery, resulting in patient discomfort and dissatisfaction. Latest research has demonstrated the efficacy of NK-1 receptor antagonists in PONV management and its use in chemotherapy nausea prophylaxis. The authors of this article would like to provide evidence to support the use fosaprepitant, as monotherapy, in postoperative care, replacing a polypharmacological standard of care regimen.. This was a retrospective chart review of 400 patients who received standard of care antiemetic regimen or received fosaprepitant (No-Fosaprepitant vs. Fosaprepitant groups, respectively). The primary outcome of this study is to evaluate the impact of fosaprepitant (administered intravenously) on perioperative antiemetic use, treatment cost, and patient satisfaction.. Total PONV medication cost decreased with the replacement of standard of care regimen for fosaprepitant, from 46.47±20.54 United States Dollars in the no-Fosaprepitant group to 25.69±14.84 United States Dollars in the Fosaprepitant group. There was a significant reduction in antiemetic doses between groups; 0.37±0.745 versus 7.61±5.202 for ondansetron ( P =0.001), 92±1.279 versus 2.21±2.399 for promethazine ( P =0.001), 0.25±0.685 versus 1.41±0.577 for scopolamine patch ( P =0.001), and 0.05±0.218 versus 1.14±0.398 for dexamethasone ( P =0.001). Patient satisfaction, measured by a questionnaire, was a 11.6% higher in the Fosaprepitant group.. Fosaprepitant is a relevant alternative in preventing and treating PONV in patients who underwent bariatric/metabolic surgical procedures.

Postoperative nausea and vomiting (PONV) are adverse effects after surgery, which may increase the risk of complications. Aprepitant is a neurokinin-1 receptor blocker and has been shown to reduce chemotherapy-related nausea and vomiting and PONV. However, its role in endoscopic skull base surgery remains unclear. The purpose of this study was to evaluate the effect of aprepitant in reducing PONV in endoscopic transsphenoidal (TSA) pituitary surgery.. A retrospective chart review between July 2021 and January 2023 of 127 consecutive patients who underwent TSA was performed at a tertiary academic institution. Patients were divided into 2 groups based on preoperative aprepitant use. Two groups were matched based on known risk factors of PONV (age, sex, nonsmoking, and history of PONV). The primary outcome was the incidence of PONV. Secondary outcome measures included the number of anti-emetic use, length of stay, and postoperative cererebrospinal fluid (CSF) leak.. After matching, 48 patients were included in each group. The aprepitant group demonstrated a significantly lower incidence of vomiting than the non-aprepitant group (2.1% vs 22.9%, p = 0.002). The number of nausea episodes and anti-emetic use decreased with aprepitant use (p < 0.05). There was no difference in the incidence of nausea, length of stay, or postoperative CSF leak. Multivariate analysis demonstrated that aprepitant decreased the incidence of postoperative vomiting with odds ratio of 0.107.. Aprepitant may serve as a useful preoperative treatment to reduce PONV in patients undergoing TSA. Further studies are needed to evaluate its impact in other arenas of endoscopic skull base surgery.

Enhanced recovery protocols (ERP) provide optimal perioperative care for surgical patients. Postoperative nausea and vomiting (PONV) is common after colorectal surgery (CRS). We aim to compare the efficacy of aprepitant to a cost-effective alternative, perphenazine, as components of triple antiemetic prophylaxis in ERP patients.. Patients who underwent ERP CRS at a single institution from July 2015 to July 2017 were evaluated retrospectively. Only subjects who received aprepitant (Group 1) or perphenazine (Group 2) preoperatively for PONV prophylaxis were included. Patient characteristics, simplified Apfel PONV scores, perioperative medications, and PONV incidence were compared between the groups. PONV was defined as the need for rescue antiemetics on postoperative days (POD) 0-5.. Five hundred ninety-seven patients underwent CRS of which 498 met the inclusion criteria. Two hundred thirty-one (46.4%) received aprepitant and 267 (53.6%) received perphenazine. The incidence of early PONV (POD 0-1) was comparable between the two groups: 44.2% in Group 1 and 44.6% in Group 2 (P = 0.926). Late PONV (POD 2-5) occurred less often in Group 1 than Group 2, respectively (35.9% vs. 45.7%, P = 0.027). After matching the groups for preoperative, procedural, and anesthesia characteristics (164 pairs), no difference in early or late PONV could be demonstrated between the groups.. The incidence of PONV remains high despite most patients receiving three prophylactic antiemetic medications. Perphenazine can be considered a cost-effective alternative to oral aprepitant for prophylaxis of PONV in patients undergoing CRS within an ERP.

Postoperative nausea and vomiting (PONV) is common with bariatric surgery. We examined the PONV rate in bariatric surgical patients who received triple antiemetic prophylaxis (dexamethasone, droperidol, and ondansetron) with and without antiemetic aprepitant.. Medical records of female patients undergoing laparoscopic bariatric surgery from January 1, 2014, to July 28, 2016, were reviewed for PONV episodes during 48 postoperative hours.. In total, 338 patients received triple antiemetic, of whom 172 (51%) also received aprepitant. Rates of PONV in the postanesthesia care unit (PACU) among patients with and without aprepitant therapy were 11 vs 17% (P = .09). Within 1 h after PACU discharge, fewer patients in the aprepitant group had PONV (19 vs 31%; odds ratio [OR] [95% CI], 0.5 [0.30-0.80]; P = .007). During the first 48 postoperative hours, PONV rates were similar between the groups (68 and 66%; P = .73), but fewer emesis episodes occurred in the aprepitant group (6 vs 13%; OR [95% CI], 0.45 [0.21-0.95]; P = .04). Analyses were also performed with a subset of patients matched on propensity for receiving aprepitant. In this subset, OR estimates quantifying aprepitant effect on PONV were similar to those obtained from multivariable regression analyses.. Addition of aprepitant to a multimodal antiemetic prophylactic regimen may be associated with significant reduction of PONV during early recovery and potentially with reduced incidence of vomiting during the first 48 postoperative hours. The high PONV rate in the first 48 postoperative hours is suggestive that introduction of scheduled anti-PONV prophylactic treatment may be desirable.

Postoperative nausea and vomiting (PONV) is frequent after joint arthroplasty; in addition to causing patient distress, it interferes with early mobilization and hospital discharge. Various antiemetic agents reduce PONV, but their action is limited by a short half-life. Aprepitant, an antiemetic developed for patients receiving chemotherapy, has a duration of action much longer than other antiemetics.. We asked whether a single dose of preoperative aprepitant (40 mg orally) reduced postoperative nausea and vomiting after THA or TKA.. Fifty patients who received a preoperative dose of aprepitant (study group) were matched demographically to 50 patients who did not receive aprepitant (control group) from a group of patients undergoing THA or TKA. Patients' charts were reviewed to identify episodes of PONV, number of doses of antiemetics needed for breakthrough PONV, and length of stay. Aprepitant side effects, and complications.. Aprepitant reduced the percentage of patients with PONV (39% of study and 70% of control patients). Moderate or severe PONV occurred in 22% of study and 40% of control patients. The number of episodes of PONV during hospitalization was 2.9 for the control group and 1.6 for the study group. Postoperatively, the control group required on average 1.3 doses of ondansetron compared with 0.6 doses for the study group. Hospital length of stay was reduced from 3.3 days for the control group and to 2.3 days for the study group.. These data suggest a single preoperative dose of aprepitant reduces the number of episodes and severity of PONV, the need for additional antiemetics, and the length of stay.. Level II, prognostic study. See guidelines for authors for a complete description of levels of evidence.

Neurokinin-1 receptor antagonists represent a new approach in the prevention of postoperative nausea and vomiting (PONV) and show an efficacy comparable with those of common antiemetics with some evidence for superiority with regard to vomiting. Currently, only aprepitant is available as an oral preparation. Palonosetron is a new representative of the serotonin-3 receptor antagonists but without the hoped for superiority on the 2nd and 3rd postoperative days. However, available data do suggest that palanosetron does not prolong the OT (c) interval. When using 5-HT (3)-receptor antagonists for the prevention of PONV, anaesthetists should be aware of negative interactions with analgesics. Low-dose droperidol has regained approval and should be considered as first choice among the current available neuroleptics.

Postoperative and postdischarge nausea and vomiting (PONV and PDNV, respectively) add morbidity to perioperative outcomes. Combining some antiemetic agents of different mechanisms is more effective than using single agents, although this concept has not yet been tested extensively with aprepitant. Consecutive high-risk patients for PONV (n = 100) were given preoperative aprepitant 40 mg before surgery and were followed perioperatively. Female patients receiving general anesthesia (n = 81) were selected for data analysis. The primary endpoints were PONV/PDNV in the 48 h after surgery. For patients included in the data analysis, using Apfel PONV risk factors, the median risk count was four out of four. PONV and PDNV incidences were 21% (95% CI: 14-31%) and 37% (95% CI: 27-48%), respectively. Two patients experienced PACU (postanesthesia care unit) vomiting and two patients experienced emesis postdischarge. When using regression modeling and comparing patients who received one or two vs. three or four mechanistically unique antiemetics (added to preoperative aprepitant), while adjusting for surgical case duration, the three or four additional antiemetic group showed more PONV/PDNV (Odds Ratio 3.73, 95% CI 1.3-10.9, p = 0.016) than did the one or two additional drug group. There were no other predictors of PONV/PDNV (transabdominal surgery, four vs. three Apfel risk factors) in these patients. The low incidence of vomiting (2-5%) suggests the potential importance of aprepitant in a multimodal antiemetic regimen. However, there may be the potential that too many unique antiemetic mechanisms combined with preoperative aprepitant may actually increase the incidence of perioperative nausea.
