CLINICAL PHARMACOLOGY Norethindrone acetate induces secretory changes in an estrogen-primed endometrium. On a weight basis, it is twice as potent as norethindrone. PHARMACOKINETICS_ _ _ABSORPTION_ Norethindrone acetate is completely and rapidly deacetylated to norethindrone (NET) after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate is rapidly absorbed from norethindrone acetate tablets, with maximum plasma concentration of norethindrone generally occurring at about 2 hours post- dose. The pharmacokinetic parameters of norethindrone following single oral administration of norethindrone acetate in 29 healthy female volunteers are summarized in Table 1. TABLE 1.
