Megestrol Acetate is a synthetic derivative of the naturally occurring female sex hormone progesterone that shows potential anti-estrogenic and antineoplastic activity. Mimicking the action of progesterone, this active ingredient binds to and activates nuclear progesterone receptors in the reproductive system. It causes the ligand-receptor complex to be translocated to the nucleus where it binds to and promotes the expression of target genes. This results in an alteration in protein synthesis, which modulates cell growth of reproductive tissues. This component also blocks luteinizing hormone release from the pituitary gland, so as to lead to an inhibition of ovulation and an alteration in the cervical mucus and endometrium. Without the stimulation of LH, estrogen hormone release from the ovaries is stopped, hence impedes the growth of estrogen-sensitive tumor cells.
