title: [Cytochrome p450 IID6, its role in psychopharmacology].
abstract: Cytochrome P450 IID6 has got typical features (genetical polymorphism, competitive inhibition, saturability) which can be at the origin of pharmacokinetic modifications of molecules using it for their metabolism. In the field of pharmacology, many molecules are substrates or inhibitors of this cytochrome. They are presented. The results of a study of the dextromethorphan variation test performed before and after 28 days of clomipramine therapy with depressed patients are explained. They show a significant decreasing of the cytochrome P450 IID6 oxidation capacities between both of these times. A patient has passed from the phenotype "effective metabolizer" to the one of "poor metabolizer" with clomipramine.
