Abstract：
:Nine healthy male subjects received oral fluconazole 400 mg daily, ketoconazole 200 mg twice daily or no treatment for 6 days according to a randomized, cross-over design. A single 250 mg oral dose of phenytoin suspension was administered on day 5 and serum phenytoin concentrations were measured over the following 48 h. Serum testosterone concentrations were measured for 10 h after each dose of phenytoin. Ketoconazole had no significant effect on phenytoin concentrations while the mean AUC(0,48) for phenytoin was significantly higher with fluconazole (195.2 +/- 47.8 micrograms ml-1 h) than control (146.3 +/- 49.6 micrograms ml-1 h). At 48 h, the serum phenytoin concentration averaged 1.72 micrograms ml-1 under control conditions and 3.99 micrograms ml-1 with fluconazole (132% increase). AUC(0,10) for testosterone was 42% lower than control after ketoconazole administration (P less than 0.05) but increased by 33% from 55.6 +/- 9.4 ng ml-1 h (control) to 73.8 +/- 12.6 ng ml-1 h with fluconazole. AUC(0,10) values for the testosterone precursors androstenedione and 17 alpha-hydroxyprogesterone were significantly higher in the fluconazole treatment phase as were concentrations of luteinizing hormone. The mechanism and clinical significance of the increase in testosterone concentration caused by fluconazole remains to be determined.
