Metabolism may be reduced by inhibitors of CYP3A4 e.g. ketoconazole, itraconazole, clotrimazole, ritonavir. Inducers of CYP3A4 e.g. rifampicin, phenytoin may reduce the levels of cyproterone.
CYP1A2 and CYP3A4 inducers such as aminoglutethimide, carbamazepine, phenobarbital, and rifampin may decrease the effects of estradiol. May enhance the effects of hydrocortisone and prednisolone when used together. Altered anticoagulant effect when used with dicoumarol.
