Published Studies Related to Tri-Norinyl (Norethindrone / Estradiol / Norethindrone / Estradiol)
Combined continuous ethinyl estradiol/norethindrone acetate does not improve forearm blood flow in postmenopausal women at risk for cardiovascular events: a pilot study. [2007.09]
OBJECTIVE: This study sought to determine whether combined continuous ethinyl estradiol and norethindrone acetate, a postmenopausal hormone therapy (HT) combination designed to have fewer side effects than cyclical therapies and therapies using medroxyprogesterone acetate (MPA), could improve vascular endothelial function in postmenopausal women with risk factors for cardiovascular disease (CVD)... CONCLUSIONS: In this older postmenopausal population with at least one cardiovascular risk factor, treatment with combined continuous ethinyl estradiol and norethindrone acetate failed to improve vascular endothelial function. The agent's proinflammatory effect or subclinical atherosclerosis in this population may have contributed to this finding.
Cycle control, tolerability, and satisfaction among women switching from 30-35 microg ethinyl estradiol-containing oral contraceptives to the triphasic norgestimate/25 microg ethinyl estradiol-containing oral contraceptive Ortho Tri-Cyclen LO. [2003.07]
OBJECTIVE: To determine cycle control, tolerability, and satisfaction among women (aged 18-45) switching from oral contraceptives (OCs) containing 30-35 microg ethinyl estradiol (EE) to Ortho Tri-Cyclen LO (norgestimate 180/215/250 microg/EE 25 microg) and Loestrin Fe 1/20 (norethindrone acetate 1 mg/EE 20 microg)...
Comparison of a novel norgestimate/ethinyl estradiol oral contraceptive (Ortho Tri-Cyclen Lo) with the oral contraceptive Loestrin Fe 1/20. [2001.06]
This multicenter study compared the contraceptive efficacy, cycle control, and safety of a new triphasic norgestimate (180/215/250 microg)/ethinyl estradiol 25 microg regimen (Ortho Tri-Cyclen Lo) (n = 1,723) with that of norethindrone acetate 1 mg/ethinyl estradiol 20 microg (Loestrin Fe 1/20) (n = 1,171)...
Comparative clinical evaluation of the effect on carbohydrate and lipid metabolism of two norethisterone-containing hormonal contraceptives: Mesigyna and TriNovum. [1997.05]
The effect on carbohydrate and lipid metabolism of two hormonal contraceptive preparations containing norethisterone (commercially known as Mesigyna and TriNovum) was studied in a total of 60 women, before and after 6 months of treatment. Carbohydrate metabolism was evaluated by means of a euglycemic glucose clamp test; lipid metabolism was monitored by measuring total cholesterol, HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol, and triglycerides...
A triphasic oral contraceptive pill, CTR-05: clinical efficacy and safety. [1996.09]
CONCLUSION: Desogestrel, with little estrogenic activity and only minimal androgenic activity, leads to lipoprotein changes, resulting in a favorable cardiovascular profile, as well as minimal androgen-related effects, such as hirsutism and acne.
Clinical Trials Related to Tri-Norinyl (Norethindrone / Estradiol / Norethindrone / Estradiol)
Study of Loestrin 24(24 Days of "Real" Pills) Fe Versus Loestrin 1/20 (21 "Real" Pills) [Active, not recruiting]
The purpose of this research study is to assess hormone withdrawal symptoms in women while
taking an oral contraceptive in the novel 24/4 (24 days of "real" pills) manner in comparison
to taking pills in the standard 21/7 (21 "real" pills) manner.
It is hypothesized that the 24/4 method will reduce common hormone withdrawal symptoms
compared to the standard 21/7 regimen.
It is further hypothesized that women using the 24/4 regimen will report greater satisfaction
scores.
TMC278-TiDP6-C136: Effect of TMC278 on Ethinylestradiol and Norethindrone in Healthy Women. [Recruiting]
The purpose of this study is to investigate the pharmacokinetic interaction between the
combination of ethinylestradiol and norethindrone and TMC278 25 mg once daily.
Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body
and eliminated from the body. Furthermore the short-term safety and tolerability (how well
the body tolerates the drug) of co-administration of TMC278 and ethinylestradiol and
norethindrone, in healthy women, will be assessed.
Treatment of Hyperandrogenism Versus Insulin Resistance in Infertile Polycystic Ovary Syndrome (PCOS) Women [Recruiting]
The goal of this three-armed randomized controlled trial is to establish the relative roles
of treatment of hyperandrogenism versus obesity (as the largest modifiable factor
contributing to insulin resistance) in treating infertility and improving pregnancy outcomes
among obese PCOS women. The investigators hypothesize that the key to restoring ovulation
leading to live birth is to correct hyperandrogenism with oral contraceptive pills, but the
key to avoiding later pregnancy complications is to improve insulin sensitivity with weight
loss.
Drug Interactions Between Lopinavir/Ritonavir and Oral or Patch Contraceptives in HIV Infected Women [Active, not recruiting]
The purpose of this study is to examine the drug interactions between a protease inhibitor
(PI)-based regimen including lopinavir/ritonavir (LPV/r) and two forms of contraceptive
medications in HIV infected women.
A Study of the Effects of GSK189075 on PK Profiles of an Oral Contraceptive Pill When Given to Healthy Female Volunteers [Active, not recruiting]
