Abstract

A sensitive (to 3 ng/ml) and specific method for analysis of the benzodiazepine antagonist Ro 15-1788 is described. The method utilizes gas-liquid chromatography with nitrogen-phosphorus detection. A neutral pH ethyl acetate extraction of 0.1–3.0 ml plasma is used for sample preparation. Standard curves using methylclonazepam as the internal standard are linear for plasma concentrations up to 200 ng/ml. Applicability of the method is demonstrated by a pharmacokinetic study in a normal volunteer who received 10 mg Ro 15-1788 intravenously.
