Mechanism of action

The effect of the drug is based on a combination of two ingredients: mepregenol propionate and ethinyl estradiol. Mepregenol propionate, acting as a progestogen, affects the secretory activity of the hypothalamus, blocking the production of gonadotropin-releasing hormone. This drug stops the synthesis of folliculotropin and luteotropin by the pituitary gland in female cats' bodies. Due to this, the development of follicles in the ovaries and their ovulation, as well as the production of female sex hormones, is slowed down. Prevention of unwanted pregnancy is provided by the combined effect of mepregenol propionate and ethinyl estradiol on the physiological state of the uterus. The mucoviscosity of the uterine cervix increased, which inhibits the mobility of spermatozoa; and changes in the endometrium of the uterus prevent the implantation of a fertilized ovum. The use of the drug contributes to the improvement of undesirable behaviour (loud partner calls, etc.). The combined action of the two active drug ingredients has allowed to reduce the amount of hormones by 50 times. All of the above ensures the safety of use and at the same time increases the effectiveness of the drug.
