Contra for females, oral, 2.5 ml (megestrol acetate)
Description:
Oily liquid for easy administration of the drug to animals.
Structure:
One package contains the active ingredient:
megestrol acetate – 50 mg.
Excipients: special liquid up to 2.5 ml.
Pharmacological properties:
Megestrol acetate is a synthetic progestogen that affects the hypothalamic-pituitary system of the animal’s body, blocks the secretion of gonadotropic hormones by the adenohypophysis (follicle-stimulating and luteinized). A decrease in the level of these hormones in the blood of animals leads to a violation of the folliculogenesis of females, which provides an antiovulatory effect on the gonads of animals. As a result, estrus is delayed, suppressed or interrupted, and libido decreases.
After the full course dose is applied, the animals’ libido is resumed after 3-4 months.
Megestrol acetate is well absorbed in the digestive tract and excreted in the urine within 1-2 days.
