Chemical structure of Methenmadinone acetate

Methenmadinone acetate (MMA) is a synthetic progestin of the 19-norprogesterone group. It is used in hormonal contraception and hormone replacement therapy.

Chemical Structure and Properties[edit | edit source]

Methenmadinone acetate is a derivative of progesterone, specifically a 19-norprogesterone. Its chemical structure is characterized by the presence of an acetate group, which enhances its bioavailability and pharmacokinetics. The molecular formula of methenmadinone acetate is C23H30O4.

Mechanism of Action[edit | edit source]

As a progestin, methenmadinone acetate acts on the progesterone receptors in the body. It mimics the effects of natural progesterone, leading to changes in the endometrium that prevent ovulation and alter the cervical mucus to inhibit sperm penetration.

Clinical Uses[edit | edit source]

Methenmadinone acetate is primarily used in contraceptive formulations. It is also utilized in hormone replacement therapy for menopausal symptoms and in the treatment of certain gynecological disorders.

Side Effects[edit | edit source]

Common side effects of methenmadinone acetate include nausea, headache, breast tenderness, and mood changes. Long-term use may be associated with an increased risk of thromboembolic events and breast cancer.

Pharmacokinetics[edit | edit source]

Methenmadinone acetate is administered orally and is well absorbed from the gastrointestinal tract. It undergoes extensive hepatic metabolism and is excreted primarily in the urine.

Related Compounds[edit | edit source]

Methenmadinone acetate is related to other 19-norprogesterone derivatives such as medroxyprogesterone acetate and norethisterone. These compounds share similar mechanisms of action but differ in their pharmacokinetic profiles and clinical applications.
