FYAVOLV

AbsorptionNorethindrone acetate (NA) is completely deacetylated to norethindrone after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate and ethinyl estradiol (EE) are absorbed from norethindrone acetate and ethinyl estradiol tablets, with maximum plasma concentrations of norethindrone and ethinyl estradiol generally occurring 1 to 2 hours postdose. Both are subject to first-pass metabolis...

14.1 Effects on Vasomotor Symptoms in Postmenopausal Women A 12-week placebo-controlled, multicenter, randomized clinical trial was conducted in 266 symptomatic women who had at least 56 moderate to severe hot flushes during the week prior to randomization. On average, women had 12 hot flushes per day upon study entry. A total of 66 women were randomized to receive norethindrone acetate and ethinyl estradiol 1/5 and 66 women were randomized to the placebo group. Norethindrone acetate and ethinyl estradiol 1/5 was shown to be statistically better than placebo at weeks 4 and 12 for relief of the...

7 DRUG INTERACTIONS Inducers and/or inhibitors of CYP3A4 may affect estrogen drug metabolism and decrease or increase the estrogen plasma concentration. ( 7.1 ) In vitro and in vivo studies have shown that estrogens are metabolized partially by cytochrome P450 3A4 (CYP3A4). Therefore, inducers or inhibitors of CYP3A4 may affect estrogen and progestin drug metabolism. Inducers of CYP3A4 such as St....
