Lydia Lacta Mechanism of Action





Full Prescribing Info
Pharmacology: Pharmacodynamics: Lydia Lacta is a progestogen-only pill, which contains the progestogen "levonorgestrel". Like other progestogen-only pill, Lydia Lacta is best suited for use during breast-feeding and for women who may not or do not want to use estrogens.
The contraceptive effect of levonorgestrel is achieved primarily by increasing the viscosity of the cervical mucus, thus reducing sperm penetration. Other effects include the decreased receptivity of the endometrium to the oocyte and the disturbed transport through the tubae. Furthermore, in about 70% of the women ovulation is inhibited.
The contraceptive efficacy of levonorgestrel approaches that of the combined Oral Contraceptive, provided the tablets are taken in accordance with the directions of use, in comparison with the combined pill, more irregular bleeding may occur with levonorgestrel whereas incidentally a period may fail to occur. Generally, after a period of adaptation, bleeding pattern with the product is acceptable.
