The Na. After establishing the selectivity of VX-548 for Na. A total of 303 participants were enrolled in the abdominoplasty trial and 274 in the bunionectomy trial. The least-squares mean difference between the high-dose VX-548 and placebo groups in the time-weighted SPID48 was 37.8 (95% confidence interval [CI], 9.2 to 66.4) after abdominoplasty and 36.8 (95% CI, 4.6 to 69.0) after bunionectomy. In both trials, participants who received lower doses of VX-548 had results similar to those with placebo. Headache and constipation were common adverse events with VX-548.. As compared with placebo, VX-548 at the highest dose, but not at lower doses, reduced acute pain over a period of 48 hours after abdominoplasty or bunionectomy. VX-548 was associated with adverse events that were mild to moderate in severity.

Opioid prescribing for postoperative pain management is challenging because of inter-patient variability in opioid response and concern about opioid addiction. Tramadol, hydrocodone, and codeine depend on the cytochrome P450 2D6 (CYP2D6) enzyme for formation of highly potent metabolites. Individuals with reduced or absent CYP2D6 activity (i.e., intermediate metabolizers [IMs] or poor metabolizers [PMs], respectively) have lower concentrations of potent opioid metabolites and potentially inadequate pain control. The primary objective of this prospective, multicenter, randomized pragmatic trial is to determine the effect of postoperative CYP2D6-guided opioid prescribing on pain control and opioid usage. Up to 2020 participants, age ≥8 years, scheduled to undergo a surgical procedure will be enrolled and randomized to immediate pharmacogenetic testing with clinical decision support (CDS) for CYP2D6 phenotype-guided postoperative pain management (intervention arm) or delayed testing without CDS (control arm). CDS is provided through medical record alerts and/or a pharmacist consult note. For IMs and PM in the intervention arm, CDS includes recommendations to avoid hydrocodone, tramadol, and codeine. Patient-reported pain-related outcomes are collected 10 days and 1, 3, and 6 months after surgery. The primary outcome, a composite of pain intensity and opioid usage at 10 days postsurgery, will be compared in the subgroup of IMs and PMs in the intervention (n = 152) versus the control (n = 152) arm. Secondary end points include prescription pain medication misuse scores and opioid persistence at 6 months. This trial will provide data on the clinical utility of CYP2D6 phenotype-guided opioid selection for improving postoperative pain control and reducing opioid-related risks.

To evaluate the prevention of opioid-induced nausea and vomiting (OINV) and the relief of moderate to severe acute pain by CL-108, a novel drug combining a low-dose antiemetic (rapid-release promethazine 12.5 mg) with hydrocodone 7.5 mg/acetaminophen 325 mg (HC/APAP) was used.. This was a multicenter, randomized, double-blind, placebo- and active-controlled multidose study. After surgical extraction of two or more impacted third molar teeth (including at least one mandibular impaction), 466 patients with moderate to severe pain (measured on a categorical pain intensity scale [PI-CAT]) were randomized to CL-108, HC/APAP, or placebo. Over the next 24 hours, patients used the PI-CAT to assess pain at regular intervals whereas nausea, vomiting, and other opioid-related side effects were also assessed prospectively. Study medications were taken every four to six hours as needed; supplemental rescue analgesic and antiemetic medications were permitted. Co-primary end points were the incidence of OINV and the time-weighted sum of pain intensity differences over 24 hours (SPID24).. Relative to HC/APAP treatment alone, CL-108 treatment reduced OINV by 64% (P < 0.001). Treatment with CL-108 significantly reduced pain intensity compared with placebo (SPID24 = 16.2 vs 3.5, P < 0.001). There were no unexpected or serious adverse events.. CL-108 is a safe and effective combination analgesic/antiemetic for the prevention of OINV during treatment of moderate to severe acute pain.

The choice of analgesic to treat acute pain in the emergency department (ED) lacks a clear evidence base. The combination of ibuprofen and acetaminophen (paracetamol) may represent a viable nonopioid alternative.. To compare the efficacy of 4 oral analgesics.. Randomized clinical trial conducted at 2 urban EDs in the Bronx, New York, that included 416 patients aged 21 to 64 years with moderate to severe acute extremity pain enrolled from July 2015 to August 2016.. Participants (104 per each combination analgesic group) received 400 mg of ibuprofen and 1000 mg of acetaminophen; 5 mg of oxycodone and 325 mg of acetaminophen; 5 mg of hydrocodone and 300 mg of acetaminophen; or 30 mg of codeine and 300 mg of acetaminophen.. The primary outcome was the between-group difference in decline in pain 2 hours after ingestion. Pain intensity was assessed using an 11-point numerical rating scale (NRS), in which 0 indicates no pain and 10 indicates the worst possible pain. The predefined minimum clinically important difference was 1.3 on the NRS. Analysis of variance was used to test the overall between-group difference at P = .05 and 99.2% CIs adjusted for multiple pairwise comparisons.. Of 416 patients randomized, 411 were analyzed (mean [SD] age, 37 [12] years; 199 [48%] women; 247 [60%] Latino). The baseline mean NRS pain score was 8.7 (SD, 1.3). At 2 hours, the mean NRS pain score decreased by 4.3 (95% CI, 3.6 to 4.9) in the ibuprofen and acetaminophen group; by 4.4 (95% CI, 3.7 to 5.0) in the oxycodone and acetaminophen group; by 3.5 (95% CI, 2.9 to 4.2) in the hydrocodone and acetaminophen group; and by 3.9 (95% CI, 3.2 to 4.5) in the codeine and acetaminophen group (P = .053). The largest difference in decline in the NRS pain score from baseline to 2 hours was between the oxycodone and acetaminophen group and the hydrocodone and acetaminophen group (0.9; 99.2% CI, -0.1 to 1.8), which was less than the minimum clinically important difference in NRS pain score of 1.3. Adverse events were not assessed.. For patients presenting to the ED with acute extremity pain, there were no statistically significant or clinically important differences in pain reduction at 2 hours among single-dose treatment with ibuprofen and acetaminophen or with 3 different opioid and acetaminophen combination analgesics. Further research to assess adverse events and other dosing may be warranted.. clinicaltrials.gov Identifier: NCT02455518.

To characterize emergency department (ED) patients' knowledge and beliefs about the addictive potential of opioids.. Mixed methods analysis of data from a randomized controlled trial.. Urban academic ED (>88,000 visits).. One hundred and seventy four discharged ED patients prescribed hydrocodone-acetaminophen for acute pain.. The study analyzed data collected from a randomized controlled trial investigating patients' knowledge of opioids. ED patients discharged with hydrocodone-acetaminophen completed an audio-recorded phone interview 4–7 days later. This analysis focuses on responses about addiction. Responses were categorized using content analysis; thematic analysis identified broad themes common across different categories.. Participants' mean age was 45.5 years (SD, 14.8), 58.6% female, 50.6% white, and the majority had an orthopedic diagnosis (24.1% back pain, 52.3% other injuries). Responses were categorized first based on whether the patient believed that opioids could be addictive (categorized as: yes, 58.7%; no, 19.5%; depends, 17.2%; or do not know, 4.6%), and second based on whether or not the patient discussed his/her own experience with the medication (categorized as: personalized, 35.6%; or not personalized, 64.4%). Cohen's Kappa was 0.84 for all categories. Three themes emerged in the thematic analysis: theme 1) patients expect to “feel” addicted if they are addicted, theme 2) patients fear addiction, and theme 3) side effects affected patient views of addiction.. In this sample, patients had misconceptions about opioid addiction. Some patients did not know opioids could be addictive, others underestimated their personal risk of addiction, and others overtly feared addiction and, therefore, risked inadequate pain management. Despite limited data, we recommend providers discuss opioid addiction with their patients.

A fixed-dose combination biphasic immediate-release (IR)/extended-release (ER) hydrocodone bitartrate (HB)/acetaminophen (APAP) tablet is being developed for the management of acute pain severe enough to require opioid treatment and for which alternative treatment options are inadequate.. This Phase III, randomized, double-blind, placebo-controlled, parallel-group study evaluated the analgesic efficacy and safety of IR/ER HB/APAP (n = 201) versus placebo (n = 202) over a period of 48 hours in patients with acute moderate to severe pain following unilateral bunionectomy. Patients received three tablets of placebo or IR/ER HB/APAP as an initial dose (hour 0) followed by two tablets every 12 hours for a total daily dose of 37.5/1625 mg HB/APAP on day 1 and 30/1300 mg HB/APAP thereafter. The primary efficacy outcome was the summed pain intensity difference (SPID) over the first 48 hours (SPID48) after the first dose.. SPID48 was significantly greater with IR/ER HB/APAP versus placebo (p < 0.001). SPID dosing interval analyses demonstrated consistent, superior pain relief with IR/ER HB/APAP for each dosing interval (all p < 0.001). Mean PID was greater with IR/ER HB/APAP versus placebo beginning 30 minutes after the first dose (p < 0.05), and IR/ER HB/APAP demonstrated faster median time to the onset of perceptible, meaningful, and confirmed pain relief (all p < 0.001). Mean total pain relief scores also indicated greater pain relief with IR/ER HB/APAP versus placebo throughout the 48-hour period (p = 0.012) for all comparisons. A greater proportion of IR/ER HB/APAP versus placebo patients was either "very satisfied" or "satisfied" with their pain relief (69.3% vs 49.4%; p < 0.001). Nausea was the most common treatment-emergent adverse event (TEAE; IR/ER HB/APAP, 25%; placebo, 7.9%). All TEAEs in IR/ER HB/APAP-treated patients were mild or moderate in severity.. IR/ER HB/APAP provided rapid, significant, and consistent analgesic efficacy over a period of 48 hours in an established model of acute pain and was tolerated with a safety profile similar to other low-dose opioids.

The objective was to test the hypothesis that oxycodone/acetaminophen provides superior analgesia to hydrocodone/acetaminophen for the treatment of acute extremity pain following emergency department (ED) discharge.. This was a prospective, randomized, double-blind clinical trial of nonelderly adult ED patients with acute musculoskeletal extremity pain, randomly allocated at discharge to receive oxycodone/acetaminophen (5 mg/325 mg) or hydrocodone/acetaminophen (5 mg/325 mg). The primary outcome was the between-group difference in improvement in numerical rating scale (NRS) pain scores over a 2-hour period following the most recent ingestion of study drug, obtained during telephone contact 24 hours after ED discharge. Secondary outcomes included proportionate decrease in pain, comparative side-effect profiles, and patient satisfaction.. A total of 240 patients were enrolled. The final sample consisted of 220 patients, 107 randomly allocated to oxycodone/acetaminophen and 113 to hydrocodone/acetaminophen. At 24 hours after ED discharge, the mean NRS pain scores prior to the most recent dose of outpatient pain medication were 7.8 and 7.9 in the oxycodone/acetaminophen and hydrocodone/acetaminophen groups, respectively. The mean decreases in pain scores over 2 hours were 4.4 NRS units in the oxycodone/acetaminophen group versus 4.0 NRS units in the hydrocodone/acetaminophen group, for a difference of 0.4 NRS units (95% confidence interval = -0.2 to 1.1 NRS units). Satisfaction with the analgesics was similar.. This study design could not detect a clinically or statistically significant difference in analgesic efficacy between oxycodone/acetaminophen (5 mg/325 mg) and hydrocodone/acetaminophen (5 mg/325 mg) for treatment of acute musculoskeletal extremity pain in adults following ED discharge. Both opioids reduced pain scores by approximately 50%.

The objective was to test the hypothesis that hydrocodone/acetaminophen (Vicodin [5/500]) provides more efficacious analgesia than codeine/acetaminophen (Tylenol #3 [30/300]) in patients discharged from the emergency department (ED). Both are currently Drug Enforcement Administration (DEA) Schedule III narcotics.. This was a prospective, randomized, double-blind, clinical trial of patients with acute extremity pain who were discharged home from the ED, comparing a 3-day supply of oral hydrocodone/acetaminophen (5 mg/500 mg) to oral codeine/acetaminophen (30 mg/300 mg). Pain was measured on a valid and reproducible verbal numeric rating scale (NRS) ranging from 0 to 10, and patients were contacted by telephone approximately 24 hours after being discharged. The primary outcome was the between-group difference in improvement in pain at 2 hours following the most recent ingestion of the study drug, relative to the time of phone contact after ED discharge. Secondary outcomes compared side-effect profiles and patient satisfaction.. The median time from ED discharge to follow-up was 26 hours (interquartile range [IQR] = 24 to 39 hours). The mean NRS pain score before the most recent dose of pain medication after ED discharge was 7.6 NRS units for both groups. The mean decrease in pain scores 2 hours after pain medications were taken were 3.9 NRS units in the hydrocodone/acetaminophen group versus 3.5 NRS units in the codeine/acetaminophen group, for a difference of 0.4 NRS units (95% confidence interval [CI] = -0.3 to 1.2 NRS units). No differences were found in side effects or patient satisfaction.. Both medications decreased NRS pain scores by approximately 50%. However, the oral hydrocodone/acetaminophen failed to provide clinically or statistically superior pain relief compared to oral codeine/acetaminophen when prescribed to patients discharged from the ED with acute extremity pain. Similarly, there were no clinically or statistically important differences in side-effect profiles or patient satisfaction. If the DEA reclassifies hydrocodone as a Schedule II narcotic, as recently recommended by its advisory board, our data suggest that the codeine/acetaminophen may be a clinically reasonable Schedule III substitute for hydrocodone/acetaminophen at ED discharge. These findings should be regarded as tentative and require independent validation in similar and other acute pain models.
