tolterodine-tartrate and imidafenacin

To carry out a network meta-analysis of randomised controlled trials (RCTs) of anticholinergic drug treatment for people with overactive bladders.. Comprehensive searches for relevant RCTs were carried out starting with RCTs included in previous systematic reviews with the last search in February 2017. Searches included terms for the anticholinergic drugs tolterodine, oxybutynin, trospium, propiverine, solifenacin, darifenacin, imidafenacin, and fesoterodine. Data was extracted from the systematic reviews or reports of studies for cure or improvement, voids per 24 hr, leakage episodes per 24 hr and dry mouth. Data was analysed using frequentist network meta-analysis.. 128 studies were found. There was no clearly best treatment for cure or improvement. The differences between treatments for voids and leakages were small and unlikely to be of clinical importance. Transdermally delivered oxybutynin was clearly the best treatment for dry mouth but was still worse than placebo.. All the anticholinergic drugs were better than placebo but apart from dry mouth were similar in effect. Transdermal oxybutynin caused less dry mouth than the other treatments, so may be worth considering as the first treatment.

Antimuscarinics (AMs) are the mainstay of pharmacological treatment of overactive bladder (OAB), a symptom complex defined by the presence of urinary urgency, usually associated with frequency and nocturia, with or without urgency urinary incontinence. The AMs used to treat OAB differ in their pharmacological profiles, which may affect their potential for causing adverse effects (AEs).. The present article aims to review the literature about pharmacokinetics (PK) of the different AMs used in the treatment of OAB. Furthermore, the AEs related to the use of these drugs and their incidence are presented. This systematic review is based on material searched and obtained via Medline, Pubmed and EMBASE up to March 2012 using the search terms "adverse events, pharmacokinetics, tolerability" in combination with "darifenacin, fesoterodine, imidafenacin, oxybutynin, propiverine, solifenacin, tolterodine, and trospium.". Antimuscarinics are the first-line pharmacological treatment for OAB. Despite the development of new molecules that improve their efficacy/safety profile, there are some drugs that are pharmacokinetically more appropriate to be prescribed in specific populations such as patients with neurological disease or the elderly. Moreover, research should be encouraged in evaluating antimuscarinics in conjunction with other drugs such as estrogens or beta-agonists. The identification of prognostic criteria for pharmacological therapy would be helpful.

This analysis was conducted to investigate the cardiovascular (CV) safety outcomes from the MILAI II study. MILAI II was conducted to evaluate the long-term safety and efficacy of antimuscarinic add-on therapy to mirabegron over 52 weeks in patients with overactive bladder (OAB) symptoms.. MILAI II consisted of a 2-week screening period (patients received mirabegron 50 mg once daily) plus a 52-week treatment period (patients were randomized to receive a combination of mirabegron 50 mg/d plus solifenacin 5 mg/d, propiverine 20 mg/d, imidafenacin 0.2 mg/d, or tolterodine 4 mg/d). CV safety was assessed using treatment-emergent adverse events (TEAEs), vital signs, and 12-lead electrocardiograms (ECGs). Vital signs and ECG data were evaluated for each patient using worst post-baseline values reported.. Of 647 patients, 570 (88.1%) were female with a mean age of 65 years. CV history at baseline and CV-related concomitant medication use throughout the study were balanced between groups. The incidences of overall and drug-related CV TEAEs were ≤8.1% and ≤6.2%, respectively, for all groups. The most common TEAEs were ECG T wave amplitude decreased, ECG QT prolonged, and ventricular extrasystoles. Overall, 36 TEAEs of interest related to the CV system that were possibly/probably related to treatment were reported with similar incidences for each group. For the worst post-baseline vital signs and ECGs, no relationships were noted in terms of either timing or treatment group.. A favorable CV safety profile was observed following long-term combination treatment with mirabegron and an antimuscarinic in patients with OAB symptoms.

To evaluate the long-term safety (primary objective) and efficacy (secondary objective) of antimuscarinic add-on therapy in patients receiving mirabegron.. During a 2-week screening period, patients (aged ≥20 years, mirabegron treatment for ≥6 weeks, residual overactive bladder symptoms) received mirabegron 50 mg once daily. These patients were subsequently randomized to 52 weeks' treatment with mirabegron 50 mg/day plus an antimuscarinic (solifenacin 5 mg, propiverine 20 mg, imidafenacin 0.2 mg, or tolterodine 4 mg) with the potential to double the antimuscarinic dose (except for tolterodine) at week 8. Safety assessments included treatment-emergent adverse events, vital signs, 12-lead electrocardiograms, post-void residual volume, and laboratory evaluations. Efficacy was assessed using changes from baseline in overactive bladder symptom score total score; overactive bladder questionnaire short form score; micturitions, urgency episodes, urinary incontinence episodes, and urgency urinary incontinence episodes/24 h; mean volume voided per micturition; and number of night-time micturitions.. Overall, 80.2% of patients (88.1% women, mean age 65 years) experienced at least one treatment-emergent adverse event, with similar rates for all treatments. The adverse events most commonly reported were dry mouth, nasopharyngitis, and constipation. No marked change was observed in systolic or diastolic blood pressure for any treatment, although pulse rate increased slightly in the mirabegron and propiverine, and mirabegron and tolterodine groups. For all treatments, significant improvements were observed in all efficacy parameters, including overactive bladder symptom score total and questionnaire short form scores.. Antimuscarinic add-on therapy is well tolerated and effective after initial treatment with mirabegron in patients with overactive bladder symptoms.

The role of the selective antimuscarinic imidafenacin in Caucasian patients with overactive bladder (OAB) has not been previously assessed.. To evaluate the safety and efficacy of imidafenacin 0.2 mg vs tolterodine 4 mg per day in patients with OAB.. This study was a randomized, open-label, tolterodine-controlled, comparative multicenter trial of 300 randomized patients with OAB symptoms for 12 weeks with full analysis of 289 patients.. Based on 5-day bladder diaries, the primary efficacy endpoint was the change in the mean number of micturitions per day. The secondary endpoints were the change in the mean incontinence episodes, voiding frequency, the OAB Awareness Tool score, and the European Quality of Life Questionnaire (EQ-5D) score. The superiority of tolterodine over imidafenacin in the mean number of micturitions/24 hours was the null hypothesis.. The median age was 46.6 years, and 82% of patients were female. After treatment, the change in the mean number of incontinence episodes was -2.1 ± 2.2 in the imidafenacin group and -1.9 ± 1.8 in the tolterodine group (P = .001). The change in the mean number of daytime incontinence episodes was -1.7 ± 1.7 and -1.5 ± 1.4 ( P = .01). The OAB Awareness Tool score decreased by 14.2 ± 8.5 and 14.5 ± 8.0, respectively ( P = 0.5). Most adverse events were mild and resolved without treatment.. The clinical efficacy and safety of imidafenacin are not inferior to those of tolterodine for the treatment of Caucasian patients with OAB.. Imidafenacin is as effective as tolterodine for the treatment of OAB.

The analysis of the results of a multicenter, open, randomized comparative phase III clinical trial on the use of imidafenacin for treating patients with OAB was carried out. A clinical study was conducted according to GCP standards in 12 urological centers of the Russian Federation with the support of company AO "R-Pharm".. A total of 296 patients (men and women) aged from 18 to 65 years with OAB and urgent urinary incontinence were included in the study. All patients were randomized into two groups. In Group 1 (n=148) patients received -cholinoblocker imidafenacin 1 tablet (0,1 mg) twice a day. Group 2 patients (n=148) were prescribed a comparison drug tolterodine 1 tablet (2 mg) twice a day, as well. The duration of treatment was 12 weeks.. The analysis of results showed a significant decrease in the OAB symptoms in both groups. In Group 1 a decrease of episodes of urge urinary incontinence was more pronounce compared to Group 2, as well as amount of day-time and night-time of episodes of urge urinary incontinence by the 2nd, 4th, 8th and 12th weeks of treatment in comparison with baseline scores. There were no differences between two groups in the severity of reducing average urinary frequency per day. Reducing the severity of urinary disturbances in patients of both groups was accompanied by an improvement in the quality of life. There was a significant and similar decrease in the average total score of both OAB Awareness Tool and EQ-5D questionnaires. Tolerability of treatment was satisfactory in both groups and there were no differences in the adverse events in Group 1 and 2.. Imidafenacin showed high clinical efficacy for treating patients with OAB, which is not inferior, and in some values, is superior in comparison to tolterodine. Both drugs had a similar safety and tolerability profile.

To investigate patient satisfaction with antimuscarinic treatment of overactive bladder syndrome, and to identify factors having a significant influence on satisfaction.. A cross-sectional questionnaire survey was carried out to assess treatment satisfaction among male and female patients with overactive bladder (age ≥20 years) in the Hokuriku district of Japan. The overactive bladder symptom scores, treatment efficacies, adverse events (dry mouth and constipation), and patient satisfaction scores were investigated and compared among patients using different antimuscarinic therapeutics.. In total, 977 survey respondents (52.6% men; mean age 73.6 years) received antimuscarinic treatment. The mean overactive bladder symptom score of these patients was 6.17; in addition, 32.3% patients were satisfied with their treatment, but 33.1% were dissatisfied. Factors having a significant influence on treatment satisfaction were sex (men were less satisfied), efficacy, adverse events and the overactive bladder symptom score. Constipation negatively influenced patient satisfaction to a greater extent than did dry mouth. Patient satisfaction varied according to the drug used. Constipation was less severe with the immediate-release-type agents (imidafenacin and oxybutynin) than with the extended-release-type (propiverine, solifenacin or tolterodine).. Just one-third of Japanese Hokuriku patients with overactive bladder seem to be satisfied with their antimuscarinic treatment. Patient satisfaction is impaired by poor efficacy and the presence of adverse events; furthermore, constipation should be recognized as an adverse event that negatively influences patient satisfaction to a greater extent than dry mouth. Patient satisfaction differs according to the antimuscarinic agent used, with higher patient satisfaction being associated with less severe constipation.

The prevalence of overactive bladder (OAB) and Alzheimer's disease (AD) increases with age, and much attention has been paid to the risk of cognitive impairment which may be induced by antimuscarinics used for OAB in patients with AD. Imidafenacin, an antimuscarinic agent for OAB treatment, has been reported not to affect learning in normal animals. However, under the condition in which sensitivity to learning impairment by antimuscarinics is increased, it remains unclear whether imidafenacin still does not impair the learning. Therefore, the influences of imidafenacin on passive avoidance response were investigated in sham-operated and nucleus basalis of Meynert (nbM)-lesioned rats and compared with oxybutynin hydrochloride and tolterodine tartrate. The learning-inhibitory doses of intravenous oxybutynin hydrochloride and tolterodine tartrate were 0.3 and 3 mg/kg in sham-operated rats and 0.1 and 1 mg/kg in nbM-lesioned rats, respectively. Thus, the learning impairments by those antimuscarinics were more sensitive in nbM-lesioned rats than in sham-operated rats. On the other hand, intravenous administration of imidafenacin had no influence on learning in either case of the rats. In normal rats, however, intracerebroventricular administration of imidafenacin impaired learning to the same degree as that of oxybutynin hydrochloride. Thus, the present study suggests that imidafenacin, unlike the other antimuscarinics used, has no significant risk of enhancing learning impairment even in models whose sensitivity to learning impairment by antimuscarinics is commonly increased, probably because of its low brain penetration.
