Sympathomimetic amines effectively control pain for interstitial cystitis that had not responded to other therapies.

To further investigate the efficacy of treatment of interstitial cystitis that had been refractory to standard treatment with sympathomimetic amines. Dextroamphetamine sulfate sustained release capsules up to 30 mg per day were prescribed in women with refractory painful bladder syndrome/interstitial cystitis in six new cases. The patients were carefully evaluated for relief of symptoms. All six women found marked relief in their painful bladder syndrome in a rather short length of time. The benefit persisted as long as the therapy was maintained. Temporary cessation resulted in prompt return of symptoms, but resumption of sympathomimetic amines again allowed good relief of bladder pain and related symptoms. Because of very few side-effects and no drug dependence in the dosage used, sympathomimetic amines should be considered for first-line therapy.
