In a pharmacokinetic interaction study in healthy volunteers with a concomitantly administered combination oral contraceptive product containing 1 mg norethindrone NET plus 35 mcg ethinyl estradiol EE topiramate, given in the absence of other medications at doses of 50 to 200 mg per day, was not associated with statistically significant changes in mean exposure AUC to either component of the oral contraceptive. In another study, exposure to EE was statistically significantly decreased at doses of 200, 400, and 800 mg per day 18%, 21%, and 30%, respectively when given as adjunctive therapy in patients taking valproic acid. In both studies, topiramate 50 mg per day to 800 mg per day did not significantly affect exposure to NET. Although there was a dose-dependent decrease in EE exposure for doses between 200 to 800 mg per day, there was no significant dose-dependent change in EE exposure for doses of 50 to 200 mg per day. The clinical significance of the changes observed is not known.
