Benzodiazepine antagonist Ro 15-1788. Antagonism of diazepam sedation in outpatients undergoing gastroscopy.

In a double-blind, randomised trial the efficacy and safety of Ro 15-1788, a new benzodiazepine antagonist, was assessed in forty adults undergoing gastroscopy under diazepam sedation. Criteria of efficacy were the degree of sedation and anterograde amnesia. There was a significantly faster recovery of the patients after the injection of 0.6-1.0 mg of Ro 15-1788 than after placebo. Patients were awake shortly after Ro 15-1788, but remained drowsy or asleep after placebo administration. There were no side effects of note.
