Comparison of tolterodine with standard treatment in pediatric patients with non-neurogenic dysfunctional voiding/over active bladder: a systematic review.

ABSTRACT

To examine the efficacy, safety and tolerability of tolterodine in children with overactive bladder in comparison with standard treatment i.e. oxybutynin as demonstrated in randomized clinical trials and other studies. A systematic search was done to screen the studies evaluating the effect of tolterodine in children with non-neurogenic overactive bladder. Results of studies were pooled and compared. Efficacy was determined from micturition diaries and dysfunctional voiding symptoms score. Safety and tolerability were assessed from the reported treatment emergent adverse events. A total of six randomized clinical trials and 11 other studies of tolterodine in children with urinary incontinence were included in the present systematic review. The dose of tolterodine used in different settings ranged from '0.5 to 8 mg/day' instead of '0.5 to 8 mg/kg per day' and the duration of studies ranged from 2 weeks to 12 months. Both extended and immediate release preparations of tolterodine were shown to have comparable efficacy and tolterodine proved to have comparable efficacy with better tolerability than oxybutynin in these studies. It can be concluded that tolterodine is efficacious in treatment of urinary incontinence in children. Moreover, its efficacy is comparable to oxybutynin, the most commonly prescribed anticholinergic in this condition, while having better tolerability. Hence, it can be considered as first line therapy for the treatmentof urinary incontinence in children.
