생화학적/생리학적 작용

Orally bioavailable synthetic progestational agent that reversibly binds to progesterone receptors with high-affinity in the hypothalamus, pituitary gland, and uterus.

Levonorgestrel (D-Norgestrel) is an orally bioavailable synthetic progestational agent that reversibly binds to progesterone receptors with high-affinity in the hypothalamus, pituitary gland, and uterus. Levonorgestrel inhibits the release of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH). D(−)-Norgestrel prevents fertilization by altering cervical mucus consistency, and interfering with the endometrial lining, making it less receptive to implantation. Levonorgestrel (LNG) can be used alone or in combination with estrogen during hormone replacement therapy.

Levonorgestrel, a standard drug for emergency contraception (EC), is not effective if administered post-ovulation. A cyclo-oxygenase inhibitor could contribute synergistic effects. We investigated whether a single 40 mg oral dose of piroxicam as co-treatment with levonorgestrel improved emergency contraceptive efficacy.
