A combination of norethindrone acetate and leuprolide acetate blocks the gonadotrophin-releasing hormone agonistic response and minimizes cyst formation during ovarian stimulation

open access: yesHuman Reproduction, 1996
A protocol utilizing both leuprolide acetate (LA) and norethindrone acetate (NETA) in subjects undergoing ovarian suppression prior to follicle aspiration proved more effective than LA alone in reducing the incidence of ovarian cyst formation without ...

Pharmacokinetics of norethindrone acetate in women after the insertion of a single subdermal implant releasing norethindrone acetate

Acta Endocrinologica, 1982
Abstract. The metabolic clearance rate (MCR) of norethindrone acetate1 (NETA) and norethindrone (NET) levels in plasma were studied after an iv injection of [3H]NETA in three women before and at 1 week, 1, 2 and 6 months following the insertion of a single silastic subdermal implant releasing microquantities of NETA. No significant change in the MCR of

Norethindrone in Serum After use of an oral Contraceptive Containing Norethindrone Acetate

Acta Obstetricia et Gynecologica Scandinavica, 1983
Abstract. 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.

Clinical evaluation of norethindrone acetate in fertility control

American Journal of Obstetrics and Gynecology, 1965
A clinical evaluation of 300 Mexican women accumulating 5902 treatment cycles representing 454 woman-years with 4 mg norethindrone acetate and .05 mg ethinyl estradiol (Anovlar) is presented. Each woman was instructed to take 1 tablet daily for 20 consecutive days beginning on Cycle Day 5. Anovlar was virtually 100% effective.

Bioavailability of norethindrone and menstrual pattern after insertion of norethindrone acetate implants in rhesus monkeys

Contraception, 1991
Subdermal silastic implants releasing norethindrone acetate were inserted in five rhesus monkeys for a period of seven months. The serum norethindrone (NET) levels were estimated from blood samples collected fortnightly. There was an initial high level of NET followed by fluctuating levels of NET in 4 out of five monkeys.

Radioimmunoassay of norethindrone: Serum levels of norethindrone in lactating women after insertion of a single silastic implant releasing norethindrone acetate

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.

A Contraceptive Vaginal Ring Releasing Norethindrone Acetate and Ethinyl Estradiol

Obstetrical & Gynecological Survey, 1994
A core design contraceptive vaginal ring (CVR) releasing 650 mcg of norethindrone acetate (NA) and 10, 20, 30 or 65 mcg of ethinyl estradiol (EE) daily was developed and tested in 99 women. The CVR inhibited ovulation well with 30 or 65 mcg EE. Vaginal bleeding was better controlled than in 23 control women using NA/EE oral contraceptives. Side effects

Programming of ovarian stimulation with norethindrone acetate in IVF/GIFT cycles

Human Reproduction, 1989
Twenty patients were given norethindrone acetate (NET) to program the initiation of controlled ovarian hyperstimulation and to coordinate follicular aspiration with surgery to obtain spermatozoa from the husband. Patients received NET, 10 mg/day orally, starting between days 2 and 4 of the cycle.

Pharmacology and Toxicology of Ethinyl Estradiol and Norethindrone Acetate in Experimental Animals

Regulatory Toxicology and Pharmacology, 2001
For over 30 years various combinations of synthetic estrogens and progestins have been used in oral contraceptive formulations. Ethinyl estradiol (EE) and norethindrone acetate (NA) are common synthetic hormones used in oral contraceptives such as Loestrin, Brevicon, Ortho-Novum, Norlestrin, and Norinyl.
