fesoterodine and Nocturia

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.

A recent study demonstrated improvement in nocturnal urgency in patients with overactive bladder when treated with fesoterodine. In the current study we aimed to determine which bladder diary parameters predict the response to fesoterodine in these patients.. Patients with nocturnal urgency completed a 2-week, single-blind placebo run-in followed by 1:1 double-blind randomization to 12 weeks of fesoterodine or placebo. We analyzed bladder diary parameter changes from baseline to week 12, including the actual number of night voids (total number of nocturia episodes), maximum voided volume, nocturnal bladder capacity, Nocturnal Bladder Capacity Index (NBCi) (actual number of night voids - nocturnal urine volume/maximum voided volume - 1), nocturnal urine volume, the nocturia index (nocturnal urine volume/maximum voided volume) and the nocturnal polyuria index (nocturnal urine volume/24-hour volume). Additionally, we analyzed OAB-q (Overactive Bladder Questionnaire) changes.. There was a linear relationship between the likelihood of being a responder for NBCi and the nocturia index. Responders had a significant decrease in nocturnal urine volume relative to baseline (-181.7 ml, p <0.01). Neither group showed a significant change in maximum voided volume relative to baseline. There was a significant decrease in NBCi and the nocturia index in responders (-0.82 and -0.61, respectively, each p <0.01). Responders demonstrated improvement in the OAB-q concern, coping, sleep, bother and total score metrics.. Patients with nocturnal urgency secondary to overactive bladder syndrome and low nocturnal bladder capacity with a mismatch between nocturnal urine production and bladder capacity may benefit from fesoterodine. Symptom improvement appears to be mediated by increases in typical rather than maximum nocturnal voided volumes. Symptom improvement was associated with improved quality of life.

To investigate the efficacy of fesoterodine vs placebo on nocturia, sleep disturbance, and sleep-related quality of life (QoL) in patients with overactive bladder and nocturia.. This posthoc analysis used data from a 12-week, randomized, placebo-controlled trial of fesoterodine 4 and 8 mg per day in Asian adults reporting ≥8 micturitions and ≥1 urgency urinary incontinence episodes per 24 hours at baseline. Patients who reported ≥1 nocturnal micturition/24 h were included in this analysis. Efficacy variables included change from baseline to week 12/end of treatment in nocturnal micturitions/24 h, nocturnal voided volume/micturition, and hours of undisturbed sleep. Sleep-related QoL was assessed using King's Health Questionnaire Sleep/Energy domain. Treatment comparisons were made using analysis of covariance.. Among 555 patients, reductions in nocturnal micturitions with fesoterodine 4 mg (-0.63) and 8 mg (-0.77) were numerically greater vs placebo (-0.56), but differences were not significant (P >.05). When patients with a nocturnal polyuria index >33% were excluded, the decrease in nocturnal micturitions was significantly greater with fesoterodine 8 mg vs placebo (-0.24; P = .031). Increases in nocturnal voided volume/micturition were significantly greater with fesoterodine 4 (38.07 mL; P = .013) and 8 mg (42.05 mL; P <.001) vs placebo (14.89 mL). Hours of undisturbed sleep was significantly longer with fesoterodine 4 mg vs placebo (80 vs 54 minutes; P = .032); improvement in King's Health Questionnaire Sleep/Energy scores was significantly greater with fesoterodine 4 (P = .034) and 8 mg (P = .019) vs placebo.. These results suggest that fesoterodine may reduce nocturnal micturitions and improve sleep quality and QoL in overactive bladder patients with nocturia.

Awakening from sleep to urinate is the hallmark of nocturia, a condition that impacts several facets of health related quality of life and for which current therapy is suboptimal. Given the paucity of prospective data on antimuscarinics for the management of nocturia, we investigated the efficacy and safety of flexible dose fesoterodine for the treatment of nocturnal urgency in subjects with nocturia and overactive bladder.. Subjects with 2 to 8 nocturnal urgency episodes per 24 hours began a 2-week, single-blind, placebo run-in followed by 1:1 randomization to 12 weeks of double-blind treatment with fesoterodine (4 mg daily for 4 weeks with an optional increase to 8 mg) or placebo using predefined criteria for nocturnal urgency episodes, nocturnal urine volume voided and total 24-hour urine volume voided. The primary end point was change from baseline to week 12 in the mean number of micturition related nocturnal urgency episodes per 24 hours.. Overall 963 subjects were randomized from 2,990 screened, and 82% of subjects treated with fesoterodine and 84% of those treated with placebo completed the study. Significant improvements in the primary end point (-1.28 vs -1.07), in nocturnal micturitions per 24 hours (-1.02 vs -0.85) and in nocturnal frequency urgency sum (-4.01 vs -3.42) were observed with fesoterodine vs placebo (all p ≤0.01). Health related quality of life measures (overactive bladder questionnaire Symptom Bother -20.1 vs -16.5, sleep 22.3 vs 19.9 and other domains; all p <0.05) were improved with fesoterodine.. To our knowledge this is the first prospective study to assess antimuscarinic efficacy for reducing nocturnal urgency. Flexible dose fesoterodine significantly reduced nocturnal urgency episodes vs placebo in subjects with overactive bladder.

We investigated treatment satisfaction with flexible-dose fesoterodine in patients with overactive bladder (OAB) who were dissatisfied with previous anticholinergic therapy.. The subjects were prescribed fesoterodine 4 mg for 4 weeks and fesoterodine 4 mg or 8 mg for another 8 weeks. The primary end point of this study was patients' satisfaction after 12 weeks of fesoterodine treatment on a five-point Likert scale. Secondary end points included a change in the number of daytime micturition, urgency incontinence episodes, urgency episodes, and nocturnal micturition in a 24-hour period from baseline to final assessment.. Overall, 84 patients were assigned to the treatment group in this study and 63 patients completed the 12-week treatment course. A final fesoterodine dose of 4 mg and 8 mg was used by 45 (71.4%) and 18 (28.6%) patients, respectively. The satisfaction and dissatisfaction rates at 12 weeks were 69.9% and 14.2%, respectively. Mean changes in the daytime micturitions (9.73 ± 4.72 vs. 7.76 ± 2.86), urgency episodes (7.73 ± 5.68 vs. 3.71 ± 4.09), and nocturnal micturitions (2.13 ± 1.36 vs. 1.68 ± 1.12) in 24 hours improved significantly with flexible-dose fesoterodine treatment (P < .05). Most adverse events were mild and none were severe.. The flexible dose fesoterodine represents an alternative treatment modality in patients with OAB who are dissatisfied with previous anticholinergic therapy in Korea.
