Abstract

A sensitive and rapid routine HPLC method is proposed for quantitative estimation of morphine hydrochloride and hydromorphone hydrochloride in pharmaceutical dosage forms. The drugs were chromatographed on a C18 reversed-phase column; the mobile phase was acetonitrile-water, 35:65 (v/v), containing sodium dodecyl sulphate (0.5%, w/v), as ion pairing reagent, and acetic acid (0.4% v/v). Detection was at 230 nm.
