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)...

Continuous, daily levonorgestrel/ethinyl estradiol vs. 21-day, cyclic levonorgestrel/ethinyl estradiol: efficacy, safety and bleeding in a randomized, open-label trial. [2009.12]
BACKGROUND: This Phase 3, randomized, open-label, multicenter study conducted at 44 sites in Europe evaluated the safety and efficacy of a continuous, daily regimen of levonorgestrel (LNG) 90 mcg/ethinyl estradiol (EE) 20 mcg compared with a 21-day, cyclic LNG 100 mcg/EE 20 mcg regimen... CONCLUSIONS: Continuous LNG 90 mcg/EE 20 mcg was shown to be a safe and effective OC in this direct comparison to a cyclic OC. Suppression of menses and the potential for no bleeding requiring sanitary protection may be provided by this continuous, low-dose OC.

A 1-year randomized study to evaluate the effects of a dose reduction in oral contraceptives on lipids and carbohydrate metabolism: 20 microg ethinyl estradiol combined with 100 microg levonorgestrel. [2005.02]
OBJECTIVES: To evaluate the impact on lipid and carbohydrate variables of a combined one-third ethinyl estradiol (EE)/levonorgestrel (LNG) dose reduction in oral contraceptives... CONCLUSION: Similar effects on the lipid and carbohydrate profiles were found for both preparations. The balanced one-third EE dose reduction in this new oral contraceptive caused slightly lower, but insignificant, changes in the lipid and carbohydrate variables compared with the reference treatment.

Superior cycle control with a contraceptive vaginal ring compared with an oral contraceptive containing 30 microg ethinylestradiol and 150 microg levonorgestrel: a randomized trial. [2005.02]
BACKGROUND: This trial was conducted to compare cycle control with vaginal ring a combined contraceptive vaginal ring, and a combined oral contraceptive (COC) delivering 30 mug ethinylestradiol (EE) and 150 mug levonorgestrel... CONCLUSIONS: Cycle control with vaginal ring was excellent and superior to that of a COC containing 30 mug EE.

A comparative study of monophasic oral contraceptives containing either drospirenone 3 mg or levonorgestrel 150 microg on premenstrual symptoms. [2005.01]
This open-label randomized study compared the effects of two combined oral contraceptives (OCs) containing 3 mg drospirenone (DRSP)/30 microg ethinyl estradiol (EE) with 150 microg levonorgestrel (LNG)/30 microg EE on the prevalence and changes from baseline of premenstrual symptoms after six cycles...
