Abstract: Phase Ⅱ drug-metabolizing reaction, characterized by the conjugation reaction, is an important way of body drug disposition. Glucuronidation, acetylation, methylation, glutathione conjugation reaction, and sulphation represent different conjugation reactions and are catalyzed by some similar genes or gene superfamily respectively. All these phase Ⅱ metabolic reactions have their own different characteristics and functional significance. Drug induced significant change of phase Ⅱ drug metabolizing enzyme activity may lead to clinical drug interactions. The genetic polymorphisms of phase Ⅱdrug metabolizing enzymes will affect the metabolism of endogenous substances, which may lead to the increased incidence of certain diseases, and these polymorphisms also affect the metabolism of exogenous substances, causing toxicity or changes in drug efficacy.

Key words: Phase Ⅱ reaction, Phase Ⅱ metabolism enzyme, Drug metabolism
