Composition of the drug:

1 tablet contains the active substance:
megestrol acetate - 5 mg.

Excipients: lactose, milk powder, microcrystalline cellulose, calcium carbonate, polyplasdon, talc, aerosol, calcium stearate, starch.
Pharmacological properties
Megestrol acetate is a synthetic progestogen, acts on the hypothalamic-pituitary system of the animal, blocks the secretion of gonadotropic hormones (follicle-stimulating and luteinizing) by the adenotropic pituitary gland. A reduced level of these hormones in the blood of animals leads to a violation of female folliculogenesis, which provides an antiovulatory effect on the gonads of animals. As a result, heat is delayed, suppressed or interrupted, and sexual drive is reduced.

After taking the full course dose, sexual desire in animals returns after 3-4 months.
Megestrol acetate is well absorbed in the digestive tract and excreted in the urine within 1-2 days.
⚠ Contraindication:
