title: Trospium chloride once-daily extended release is efficacious and tolerated in elderly subjects (aged ≥ 75 years) with overactive bladder syndrome.
abstract: OBJECTIVE
  • To evaluate the safety and efficacy of once-daily trospium chloride extended release (ER) in overactive bladder syndrome (OAB) in subjects aged ≥ 75 years.
  
  
  METHODS
  • The analysis included subjects ≥ 75 years of age with OAB. • A subgroup analysis of pooled data was performed for subjects aged ≥ 75 years from two randomized, double-blind, multicenter studies of subjects with OAB receiving once-daily trospium 60 mg extended release (ER) or placebo for 12 weeks, followed by 9-month open-label extension periods during which all subjects received trospium ER. A total of 143 of the 1165 subjects from two phase III registration trials who were aged ≥ 75 years (85 trospium ER, 58 placebo; mean age 79 years and ranging up to 90 years; 73% female) were evaluated. • Dual primary efficacy variables were the changes from baseline in the average number of toilet voids per day and urge urinary incontinence episodes per day.
  
  
  RESULTS
  • At week 12 of the double-blind period, trospium ER produced greater improvements from baseline than placebo in voiding diary parameters, OAB Patient Global Assessment, and quality of life. • Efficacy and tolerability persisted among subjects receiving open-label trospium ER for up to 1 year.
  
  
  CONCLUSIONS
  • Once-daily trospium chloride 60 mg ER demonstrated efficacy vs placebo and was tolerated in subjects aged ≥ 75 years with OAB. • For subjects who continued into the open-label treatment period, efficacy and tolerability were observed for up to 1 year.
