A double-blind, cross-over study of the effects of terodiline in women with unstable bladder.

In a double-blind, cross-over study, the effects of terodiline were evaluated in 12 women with motor urge incontinence. The patients were investigated by simultaneous urethro-cystometry before and after treatment fo 2-week periods with placebo and terodiline 12.5 mg twice daily. The effects on subjective symptoms were also assessed. In all patients but one, terodiline increased the bladder capacity and also the bladder volume at which urgency was experienced. No effects on the urethral pressure profile or residual urine were found. Subjective improvement was reported by all but one of the patients. Placebo treatment had no effect on the measured parameters or on the subjective symptoms. No side effects were reported during any of the treatment periods. --It is concluded that terodiline can be used for treatment of female motor urge incontinence, and that it is a promising alternative to drugs presently used for this disorder.
