First dual-protection intravaginal ring design shows promise in long-term HIV & pregnancy prevention
Source: Clinical Trials / Drug Trials News From Medical News Today [2013.11.12]
A new intravaginal ring (IVR) has been developed for the sustained 90-day co-delivery of tenofovir and levonorgestrel, an anti-human immunodeficiency virus (HIV) drug and a contraceptive. Tenofovir is the only topical prophylactic shown to be effective at reducing the sexual transmission of HIV when formulated in a gel.

Published Studies Related to Ovrette (Norgestrel)
An overview of four studies of a continuous oral contraceptive (levonorgestrel 90
mcg/ethinyl estradiol 20 mcg) on premenstrual dysphoric disorder and premenstrual
and premenstrual syndrome (PMS)... CONCLUSIONS: These data, although not consistent, indicate that continuous LNG/EE
Effect of ticagrelor on the pharmacokinetics of ethinyl oestradiol and levonorgestrel in healthy volunteers. [2011.08]
BACKGROUND: Cytochrome P450 3 A is involved in ticagrelor and ethinyl oestradiol/levonorgestrel metabolism; so a potential drug-drug interaction may occur. OBJECTIVES: To assess: ticagrelor effects on ethinyl oestradiol/levonorgestrel pharmacokinetics, endogenous sex hormone levels; ethinyl oestradiol/levonorgestrel effects on ticagrelor pharmacokinetics; tolerability of ticagrelor + ethinyl oestradiol/levonorgestrel... CONCLUSIONS: Ticagrelor co-administration with ethinyl oestradiol/levonorgestrel increased ethinyl oestradiol exposure by approximately 20%, with no effect on levonorgestrel pharmacokinetics. No clinically relevant effect on contraceptive efficacy is expected with ethinyl oestradiol/levonorgestrel and ticagrelor co-administration.
Haemostatic effects of a new combined oral contraceptive, nomegestrol acetate/17beta-estradiol, compared with those of levonorgestrel/ethinyl estradiol. A double-blind, randomised study. [2011.03]
Use of oral contraceptives (OC) that combine a progestogen with synthetic ethinyl estradiol (EE) is associated with increased risk of venous thromboembolism. NOMAC/E2 is a new monophasic OC that combines nomegestrol acetate (NOMAC), a highly selective progestogen, with 17beta-estradiol (E2)...
A randomized clinical trial of a levonorgestrel-releasing intrauterine system and a low-dose combined oral contraceptive for fibroid-related menorrhagia. [2011.02]
OBJECTIVE: To compare the efficacy of a levonorgestrel-releasing intrauterine system (LNG-IUS) with that of a low-dose combined oral contraceptive (COC) in reducing fibroid-related menorrhagia... CONCLUSION: Although the rate of treatment failure was similar in both groups, the LNG-IUS was more effective in reducing MBL than the COC in women with fibroid-related menorrhagia.

Hormone Therapy in Preventing Endometrial Carcinogenesis (Cancer) in Women With a Genetic Risk For Hereditary Nonpolyposis Colon Cancer [Active, not recruiting]
RATIONALE: Hormone therapy may prevent the development of endometrial carcinogenesis (cancer)
in women with a genetic risk for hereditary nonpolyposis colon cancer. It is not yet known
which hormone therapy regimen is more effective in preventing endometrial cancer.
PURPOSE: Randomized phase II trial to compare two different hormone therapy regimens in
preventing endometrial cancer in women who have a genetic risk for hereditary nonpolyposis

A Comparative Pharmacokinetic Study of ORTHO EVRA® (a Transdermal Contraceptive Patch) and CILEST® (an Oral Contraceptive) in Healthy Female Volunteers [Completed]
The objective of this study is to compare the levels of the hormones norelgestromin,
norgestrel, and ethinyl estradiol in the bloodstream of healthy female volunteers
administered ORTHO EVRA® (a transdermal contraceptive patch) and CILEST® (an oral
