AFTER ORAL OR IP ADMIN OF (15)N-LABELLED PHENOXYBENZAMINE HYDROCHLORIDE TO RATS (20 MG/KG BODY WT) & AFTER ORAL ADMIN TO DOGS (10 MG/KG BODY WT), THE FOLLOWING URINARY METABOLITES WERE IDENTIFIED: N-BENZYL-N-(PARA-HYDROXYPHENOXYISOPROPYL)AMINE WAS FOUND TO BE THE MAJOR METABOLITE IN BOTH SPECIES; N-BENZYL-N-PHENOXYISOPROPYLAMINE WAS THE MINOR METABOLITE IN DOGS & WAS ALSO OBSERVED IN SMALL AMT IN RATS, ONLY AFTER IP INJECTION; & PHENOXYISOPROPYLAMINE WAS FOUND TO BE A METABOLITE IN DOGS. 2-BENZYLAMINO-1-PROPANOL WAS FOUND IN RAT URINE AFTER IP BUT NOT AFTER ORAL DOSING. /PHENOXYBENZAMINE HYDROCHLORIDE/
N-BENZYL-N-(PARA-HYDROXYPHENOXYISOPROPYL)AMINE WAS IDENTIFIED IN THE URINE OF TWO PT TREATED ORALLY WITH 10 MG/DAY PHENOXYBENZAMINE HYDROCHLORIDE. /PHENOXYBENZAMINE HYDROCHLORIDE/

吸收、分配和排泄
从胃肠道吸收是不完全且多变的,口服给药后,只有大约20到30%的药物以活性形式被吸收。
Absorption from the gastrointestinal tract is incomplete and variable, and only about 20 to 30% of the drug is absorbed in an active form after oral administration.
PHENOXYBENZAMINE COMBINES IRREVERSIBLY WITH SMOOTH MUSCLE ADRENERGIC EXCITATORY RECEPTORS, THROUGH ALKYLATION, SO THAT COMPLETE BLOCKAGE, ONCE INDUCED, MAY LAST FOR SEVERAL DAYS.
IV INJECTION OF /0.54 MG/ (14)C-PHENOXYBENZAMINE HYDROCHLORIDE IN NMRI MICE REMAINED IN BLOOD FOR 40 MIN. RADIOACTIVE MATERIAL WAS THEREAFTER FOUND IN BROWN FAT, LIVER & KIDNEY; OTHER ORGANS (NOTABLY THE HEART & CNS) ATTAINED RELATIVELY HIGHER ACTIVITY, WHICH PERSISTED FOR 4 DAYS /BILIARY EXCRETION WAS AN IMPORTANT ROUTE OF ELIMINATION/. 4 HR AFTER IV INJECTION OF (14)C-PHENOXYBENZAMINE HYDROCHLORIDE, THE BILE FROM 2 ANESTHETIZED MALE SPRAGUE-DAWLEY RATS CONTAINED 29.3% & 32.8% OF ADMIN RADIOACTIVITY. /PHENOXYBENZAMINE HYDROCHLORIDE/
