Mecanismo de acción (Mechanism of Action)

Targets/IC₅₀/Ki	Progesterone receptor
In vitro	Levonorgestrel suppresses the stimulation of progesterone secretion induced by oLH, dibutyryl-cAMP and Pregnenolone in rats luteal cells. This compound also inhibits constrictions evoked by either a high potassium (K(+)) solution or phorbol myristate acetate (PMA) in the absence and presence of extracellular calcium (Ca(2+)). It depresses contractions evoked by Ca(2+) and reduces (45)Ca(2+) influx in depolarized veins. The chemical increases levels of cyclic AMP and inhibits PMA-induced activation of protein kinase C in veins. It causes endothelium-independent relaxations of jugular veins via inhibition of Ca(2+) entry and of protein kinase Cactivation. Its inhibition of both estrogen-induced pituitary weight increment and hyperprolactinemia is reduced by mifepristone, whereas Flutamide is unable to block this compound's effects
In vivo	Levonorgestrel down-regulates the mRNA expression of follicle-stimulating hormone receptor (FSHR), luteinizing hormone receptor (LHR), estrogen receptor (ER) β and progesterone receptor (PR) in the ovary, and ERα and PR in the uterus of Mongolian gerbils. This compound causes a significant upregulation of the mRNA expression of the gene encoding luteinising hormone β-subunit (lhβ) and the suppression of the mRNA expression of the gene encoding follicle-stimulating hormone β-subunit (fshβ) in the pituitary of both male and female roach. It disrupts the reproductive system of pubertalroach by affecting the pituitary gonadotropin expression and the sex steroid levels in pubertal roach (Rutilus rutilus).
