Drug Metabolite

Drug metabolite results when a drug is metabolized into a modified form which continues to produce effects. Drug metabolism redox reactions such as heteroatom dealkylations, hydroxylations, heteroatom oxygenations, reductions, and dehydrogenations can yield active metabolites, and in rare cases even conjugation reactions can yield an active metabolite.
