13656-78-5 Usage
General Description
"17-hydroxy-16beta-methyl-5beta-pregn-9(11)-ene-3,20-dione" is a synthetic steroid hormone known as medroxyprogesterone acetate (MPA). It is a progestin medication that works by suppressing ovulation, thickening cervical mucus to prevent sperm from reaching the egg, and altering the uterine lining to prevent implantation of a fertilized egg. MPA is commonly used in birth control pills, hormone replacement therapy, and to treat menstrual problems, endometriosis, and certain types of cancer. It has a similar chemical structure and function to the hormone progesterone, and is generally well-tolerated by most individuals when used as directed by a healthcare provider. However, like all medications, it may cause side effects and should be used with caution in certain populations, such as individuals with a history of blood clots or certain types of cancer.
