HARMACODYNAMICS/PHARMACOKINETICS 4.1 PHARMACODYNAMIC PROPERTIES Pharmacotherapeutic group: Progestogens and estrogens, fixed combinations, ATC code: G03AA. The continuous intake of Belara for 21 days inhibits pituitary FSH and LH secretion, and thus ovulation. The endometrium proliferates and undergoes secretory transformation. The consistence of the cervical mucus is changed. This prevents sperm migration through the cervical canal and alters sperm motility. The lowest daily dose of chlormadinone acetate for complete inhibition of ovulation is 1.7 mg. The full endometrial transformation dose is 25 mg per cycle. Chlormadinone acetate is an antiandrogenic progestogen. Its effect is based on its ability to displace androgens from their receptors. Clinical efficacy 2 In clinical studies in which the administration of Belara was tested for up to 2 years in 1655 women and more than 22 000 menstruation cycles, there were 12 pregnancies. In 7 women administration errors, concomitant diseases causing nausea or vomiting, or concomitant administration of medicines known to reduce the contraceptive effect of hormonal contraceptives were present in the period of conception.
