At a glance

Cyproterone Acetate + Ethinyl Estradiol is a hormonal preparation used for the treatment of severe acne, seborrhea and mild hirsutism.

Description

Cyproterone Acetate + Ethinyl Estradiol belongs to the oral contraceptive preparations and oral hormonal preparations for acne group. This preparation tablet is indicated for the treatment of women with severe acne, unresponsive to oral antibiotic and other available treatments, with associated symptoms of androgenization, including seborrhea and mild hirsutism. Cyproterone is a steroid compound with potent antiandrogenic, progestogenic and antigonadotrophic activity. It exerts its antiandrogenic effect by blocking androgen receptors. It also reduces androgen synthesis by a negative feedback effect on the hypothalamo-pituitary-ovarian systems. The estrogen component (Ethinylestradiol) increases levels of sex hormone binding globulin (SHBG) and thus reduces the free circulating plasma levels of androgens.

  • Seborrhea
  • Mild hirsutism
  • Associated symptoms of androgenization

Pharmacology

Cyproterone is a steroid compound with potent antiandrogenic, progestogenic and antigonadotrophic activity. It exerts its antiandrogenic effect by blocking androgen receptors. It also reduces androgen synthesis by a negative feedback effect on the hypothalamo-pituitary-ovarian systems. The estrogen component (Ethinylestradiol) increases levels of sex hormone binding globulin (SHBG) and thus reduces the free circulating plasma levels of androgens. Cyproterone has no tendency to reduce SHBG levels.

Mechanism of action

Cyproterone blocks androgen receptors and reduces androgen synthesis via negative feedback on the hypothalamo-pituitary-ovarian systems. Ethinylestradiol increases SHBG levels, reducing free circulating androgens. Together, they prevent ovulation and improve androgen-related conditions.

Dosage

First Treatment Course: The patient is instructed to take 1 tablet daily for 21 consecutive days beginning on day 1 of her menstrual cycle. The tablets are then discontinued for 7 days (1 week).

Subsequent Courses: The patient begins her next and all subsequent 21-day course of tablets (following the same 21 days on, 7 days off) on the same day of the week that she began her first course.

Treatment should be continued for several months, since improvement may not be observed for at least 3 months. The drug should be discontinued 3 to 4 cycles after signs have completely resolved.

Take 1 tablet daily at the same time each day. Take the first tablet from the blister pack out of the section marked with the corresponding day of the week and swallow it with some liquid.

If more than 12 hours have elapsed, the missed tablet must be discarded and the remaining tablets continued at the usual time.
