Ethinylestradiol/chlormadinone acetate (EE/CMA) is an effective oral contraceptive for preventing pregnancy. This combined pill also demonstrated superior efficacy in treating facial acne compared to another common contraceptive.

Area of Science:

Pharmacology
Gynecology
Dermatology

Background:

Ethinylestradiol/chlormadinone acetate (EE/CMA) is a combined monophasic oral contraceptive.
It possesses antiandrogenic properties, suggesting potential therapeutic applications beyond contraception.

Purpose of the Study:

To evaluate the efficacy and tolerability of EE/CMA for pregnancy prevention.
To assess the effectiveness of EE/CMA in treating mild-to-moderate papulopustular facial acne.

Main Methods:

A large, noncomparative, multicentre trial and postmarketing surveillance studies assessed contraceptive efficacy and safety.
A randomized, single-blind, multicentre trial compared EE/CMA with ethinylestradiol/levonorgestrel for acne treatment.

Main Results:

EE/CMA demonstrated effectiveness in preventing pregnancy across multiple studies.
EE/CMA showed significantly greater efficacy in treating facial acne compared to ethinylestradiol/levonorgestrel.
The contraceptive was generally well-tolerated, with adverse events typical of oral contraceptives, including menstrual disturbances.

Conclusions:

EE/CMA is an effective oral contraceptive with a favorable safety profile.
EE/CMA offers a more effective treatment option for mild-to-moderate facial acne in women compared to ethinylestradiol/levonorgestrel.
