摘要: The systemic availability of orally administered imipramine (IP) varied from 29 to 77% in 4 subjects. decrease was due an excess metabolism after oral administration. This first%pass did not correlate with plasma half%life, apparent clearance, or the rate metabolite excretion urine. There close correlation formation demethylated metabolites administration, which suggests that is mediated by demethylation, but does total demethylation.
