IndicationFor treatment of female infertility
PharmacodynamicsUsed for the treatment of female infertility, Follitropin beta or follicle stimulating hormone (FSH) stimulates ovarian follicular growth in women who do not have primary ovarian failure. FSH, the active component of Follitropin beta is the primary hormone responsible for follicular recruitment and development.
Mechanism of actionFollitropin alpha is a recombinant form of endogenous follicle stimulating hormone (FSH). FSH binds to the follicle stimulating hormone receptor which is a G-coupled transmembrane receptor. Binding of the FSH to its receptor seems to induce phosphorylation and activation of the PI3K (Phosphatidylinositol-3-kinase) and Akt signaling pathway, which is known to regulate many other metabolic and related survival/maturation functions in cells.
