Brief summary

The purpose of this study is to assess the pharmacokinetic profiles of norethisterone and ethinyl estradiol after single oral administration of NPC-01 in healthy female volunteers. Pharmacokinetics of norethisterone and ethinyl estradiol will be evaluated on the basis of AUC, Cmax, tmax, t1/2, MRT, kel and AUC∞.
