Abstract

A highly sensitive method (∼1 ng/ml) for single‐dose pharmacokinetic studies of diphenhydramine which utilizes GLC with nitrogen–phosphorus detection is described. Standard curves, using orphenadrine as the internal standard, were linear for diphenhydramine concentrations from 1.0 to 300 ng/ml. Applicability of the method was demonstrated by a pharmacokinetic study in a normal volunteer who received 25 mg iv of diphenhydramine.
