Drug Mode of Action ::  

Cyproterone is a progestogen with anti-androgenic properties.Oestradiol is the major oestrogen in pre-menopausal women. Ethinylestradiol has similar actions as oestradiol. It is responsible for the development and maintenance of female reproductive system and secondary sexual characteristics. It also inhibits anterior pituitary by negative feedback effect and causes capillary dilation, fluid retention and protein anabolism.

Drug Interactions ::

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. Potentially Fatal: Antibiotics (ampicillin, tetracycline, sulphonamides and chloramphenicol) can cause intermenstrual bleeding or failure of contraception. Reduced efficacy of antihypertensives or hypoglycaemic drugs.
