Indications for use
Mechanism of action
Kurvelo is a combined, oral monophase contraceptive drug containing 2 hormones – gestagen and progestin. It inhibits ovulation by blocking the secretion of follicle-stimulating and luteinizing hormones in the pituitary gland, promoting the secretory transformation of the endometrium, increasing the cervical mucus viscosity.
The successive intake of tablets of the drug, containing different amounts of progestin (levonorgestrel) and estrogen (ethinyl estradiol), makes it possible to renew and provide the constant level of these hormones in the blood, closely relating to physiological, followed by normalization of menstrual dysfunctions.
