Bioavailability of norethindrone in human subjects
European Journal of Clinical Pharmacology, 1978A competitive protein binding assay for norethindrone was developed to measure plasma levels in human subjects. The plasma levels were considerably higher in women than in men, especially at low dose levels. The plasma levels were directly related to the dose in men; but greater variations in the plasma levels were observed in women.

Retrospective Review of Norethindrone Use in Adolescents
Journal of Pediatric and Adolescent Gynecology, 2014Our objectives were to review norethindrone use in an adolescent population in a tertiary care center and to assess the effectiveness of the norethindrone taper in the management of acute heavy menstrual bleeding in adolescents.Retrospective cohort study.Tertiary care center.176 adolescent females prescribed norethindrone 0.35 mg between July 2007 and ...

Pharmacokinetics of norethindrone acetate in women
American Journal of Obstetrics and Gynecology, 1979The plasma half-life, MCR and plasma metabolite levels at various time intervals have been studied in six women after an intravenous injection of 3H-norethindrone acetate. The disappearance curve due to norethindrone acetate showed an initial rapid disappearance of 3H with an average half-life of 7.5 minutes and a subsequent slow disapperance with a ...

Norethindrone in Serum After use of an oral Contraceptive Containing Norethindrone Acetate
Acta Obstetricia et Gynecologica Scandinavica, 1983Abstract. The availability of norethindrone (NET) in serum was studied in 8 women after daily administration of a combination oral contraceptive pill (MinovlarR) containing 1 mg norethindrone acetate (NETA) and 50 μg ethinyl estradiol (EE2) from day 5 to day 25 of the menstrual cycle. The pill was taken daily at 9.30 a.m.

Plasma levels of norethindrone after I.M. injection of 200 mg norethindrone enanthate
Contraception, 1975Abstract The plasma levels of norethindrone were measured with a radioimmunoassay after an intramuscular injection of 200 mg of norethindrone enanthate in five healthy women. After an initial peak of norethindrone between 8–14.5 ng/ml, a gradual decline followed. The concentration of 1 ng/ml was reached after approximately 45 days. The plasma pattern

Clinical Endocrinology, 1979
SUMMARYSingle oral doses of 0.3 mg, 0.5 mg and 5 mg Norethindrone (NET) and 0.5 mg and 5 mg Lynestrenol (lyn) were given to five women. Lynestrenol is probably metabolized through NET and exerts its main biological activity as NET. Plasma concentrations of NET were determined by a radioimmunoassay at different intervals after administration of the ...

Contraception, 1978
A specific radioimmunoassay was developed for the estimation of norethindrone levels in the serum of lactating women. A conjugate of norethindrone-3-BSA was synthesized and antiserum raised against it in rabbits. The antiserum showed high affinity (1.5 x 10(9)M/L) and titer and was specific. The sensitivity of the assay was 125 pg/ml serum.

Pharmacokinetics of norethindrone in Indian women
Contraception, 1979Pharmacokinetics of norethindrone (NET) was evaluated in eleven women belonging to a low socio-economic group and in five womem belonging to the high socio-economic group after the administration of an oral dose of 0.35 mg NET minipill on an empty stomach. Blood samples were collected at different intervals of time over a period of 24 hours. Plasma NET

Structure of the Isonicotinyl Hydrazone of Norethindrone
Journal of Pharmaceutical Sciences, 1983The contraceptive steroid norethindrone reacts with isoniazid both in vivo and in vitro to give the corresponding hydrazone, which exists as syn and anti (with respect to C-4) isomers. These isomers rapidly interconvert, with the anti form predominating in solution.
