• Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism ( 7.1 ) • Aminoglutethimide administered concomitantly with MPA may significantly depress the bioavailability of medroxyprogesterone acetate ( 7.1 ) 7.1 Metabolic Interactions In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Aminoglutethimide administered concomitantly with MPA may significantly depress the bioavailability of MPA.

Inhibitors of CYP3A4, such as erythromycin, clarithromycin, ketoconazole, itraconazole, ritonavir and grapefruit juice, may increase plasma concentrations of estrogens and may result in side effects.
