title: Evaluation of the possible interaction of the antifungal triazole SCH 39304 with oral contraceptives in normal healthy women.
abstract: The possible interaction of the newly developed triazole antifungal SCH 39304 with low-dose combined oral contraceptives (OCs) was studied in 15 healthy women. Serum levels of ovarian and adrenocortical steroids and sex hormone-binding globulin (SHBG) were analyzed in samples collected during the OC cycles immediately before, during and after the administration of SCH 39304. The drug was given as a single 400-mg oral dose on day 7 in the second cycle. SCH 39304 did not interfere with the ovulatory inhibitory action of low-dose combined OCs as judged from serum progesterone values. Administration of SCH 39304 caused minor decreases in serum SHBG, cortisol and dehydroepiandrosterone sulfate. The mechanism(s) behind these minor changes is not known.
