DESCRIPTION
Norethindrone acetate tablets, USP - 5 mg oral tablets.
Norethindrone acetate tablets, USP,
(17-hydroxy-19-nor-17α-pregn-4-en-20-yn-3-one acetate), a
synthetic, orally active progestin, is the acetic acid ester of
norethindrone. It is a white to creamy white,
odorless, crystalline powder.
Norethindrone acetate tablets, USP contain the following inactive
ingredients: anhydrous lactose,
magnesium stearate, methylene chloride, and microcrystalline
cellulose.
Meets USP Dissolution Test 2.
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.
