Abstract
- Normorphine metabolism was studied in dogs given 20 mg of normorphine hydrochloride/kg sc. Free and (onjugated normorphine excreted in the urine over 144 hr represented 32 and 32%, respectively, of the administered dose. Eighty percent of the urinary excretion of the drug occurred within 9 hr. One percent of the administered dose was excreted as free normorphine in the feces. The urine was chromatographed on a column. Evaporation of the washing and methanolic effluent yielded a residue, which was purified by crystallization from aqueous methanol. Results of UV and IR studies, elemental analysis, and determination of normorphine and glucuronic acid content established the identity of this metabolite as normorphine 3-glucuronide. Dihydronormorphine and dehydronormorphine were detected with GLC-mass spectrometry as minor metabolites.
