This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.

Published Studies Related to Nortrel 7 / 7 / 7 (Norethindrone / Estradiol / 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.

HT update: spotlight on estradiol/norethindrone acetate combination therapy. [2008]
Abstract: The goal ofpostmenopausal hormone therapy is to alleviate the symptoms that are associated with the loss of estrogen. Many formulations of estrogen and progestin are available, depending on the needs and circumstances of each individual woman... The purpose of this review is to describe the risks and benefits of hormonal therapy, focusing on estradiol/norethindrone acetate combination therapy.

A multicenter, open-label study to evaluate satisfaction and menopausal quality of life in women using transdermal estradiol/norethindrone acetate therapy for the management of menopausal signs and symptoms. [2005]
AIM: This multicenter, open-label, single-arm study evaluated subject satisfaction and improvements in menopausal quality of life among menopausal women using the CombiPatch transdermal system consisting of 17beta-estradiol 0.05 mg plus norethindrone acetate 0.14 mg in a matrix patch formulation... CONCLUSIONS: The results of this study compare favorably with previous placebo-controlled studies of transdermal hormone therapy in managing menopausal signs and symptoms. Furthermore, quality of life was significantly improved by the transdermal hormone therapy system, and both subjects and physicians reported high levels of satisfaction. Copyright 2005 S.

Pharmacokinetic interaction between nevirapine and ethinyl estradiol/norethindrone when administered concurrently to HIV-infected women. [2002.04.15]
OBJECTIVE: To determine the effects of nevirapine (NVP), a nonnucleoside reverse-transcriptase inhibitor of HIV-1 and P450 inducer, on the pharmacokinetics (PK) of ethinyl estradiol (EE)/norethindrone (NET), a widely used oral contraceptive, and to assess the effects of EE/NET on the steady-state PK of NVP... CONCLUSION: Oral contraceptives should not be the primary method of birth control in women of child-bearing potential who are treated with NVP.

Clinical Trials Related to Nortrel 7 / 7 / 7 (Norethindrone / Estradiol / 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.

A Study in Healthy Female Participants Investigating the Effect of TMC435 on the Pharmacokinetics of the Synthetic Hormones of the Oral Contraceptive Ovysmen [Recruiting]
The purpose of this study is to investigate the effect of steady-state concentrations of TMC435 (administered once a day) on the steady-state pharmacokinetics of ethinylestradiol and norethindrone (administered once a day) and on the levels of progesterone, luteinizing hormone and follicle-stimulating hormone, in healthy female participants. Ethinlyestradiol and norethindrone are synthetic hormones, which constitute the oral contraceptive Ovysmen. Also the short-term safety and tolerability of the co-administration of TMC435 and Ovysmen will be studied. Steady-state is a term that means that the drug has been given long enough so that the plasma concentrations will remain the same with each subsequent dose. TMC435 is being investigated for the treatment of chronic hepatitis C virus (HCV) infection. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. A contraceptive is a method that prevents pregnancy.

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.

Gender Disparity and Hormones in Cystic Fibrosis [Recruiting]
The objective of this study is to investigate the impact of hormones on lung disease in Cystic Fibrosis (CF) patients. Due to improved therapies, CF patients are living longer and healthier lives than they did 20 years ago. However, females have been shown to have a survival disadvantage. The median life expectancy is 33 in women and 37 in men with CF. The hypothesis is that estrogen and/or progesterone negatively impact lung health in CF. Therefore, understanding the impact of sex hormones (including the use of birth control pills) on the disease process is increasingly important. The purpose of this study is to determine if lung function, respiratory symptoms, or various markers of lung health change during different phases of the natural ovulatory cycle in order to understand if estrogen or progesterone hormones are impacting the disease relative to fluctuations in men with stable testosterone levels. The research objectives of this project are to:

- Determine if lung function, respiratory symptoms, or various markers of lung health

change during different hormonal phases of the ovulatory cycle in women.

- Determine if men change lung function, respiratory symptoms, or various markers of lung

health over time.

- Determine if oral contraceptive pills in women stabilize fluctuations in symptoms and

improve lung health.

Oral Contraceptive (OC) Estrogen Dose and Breast Proliferation [Recruiting]
The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of estrogen (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of estrogen; this research will examine that in detail. This research will also test whether the results found in HS-07-00269 can be confirmed.
