Hydromadinone acetate

Hydromadinone acetate is a synthetic progestin of the 17α-hydroxyprogesterone group. It is used in hormonal contraception and hormone replacement therapy.

Chemical Structure and Properties

Hydromadinone acetate is a derivative of progesterone, specifically a 17α-hydroxyprogesterone derivative. Its chemical structure is characterized by the presence of an acetate group at the 17α position. This modification enhances its bioavailability and pharmacokinetics.

Mechanism of Action

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

Medical Uses

Hydromadinone acetate is primarily used in hormonal contraception and hormone replacement therapy. It is often combined with an estrogen in combined oral contraceptive pills to provide effective birth control.

Hormonal Contraception

In hormonal contraception, hydromadinone acetate is used to prevent ovulation and create an inhospitable environment for sperm in the female reproductive system. It is effective in reducing the risk of pregnancy when taken as directed.

Hormone Replacement Therapy

In hormone replacement therapy, hydromadinone acetate is used to alleviate symptoms of menopause such as hot flashes, vaginal dryness, and osteoporosis. It is often prescribed in combination with an estrogen to balance the hormonal levels in the body.

Side Effects

Common side effects of hydromadinone acetate include nausea, headache, breast tenderness, and mood changes. Serious side effects may include an increased risk of blood clots, stroke, and breast cancer.

Contraindications

Hydromadinone acetate is contraindicated in individuals with a history of thromboembolic disorders, liver disease, breast cancer, and undiagnosed vaginal bleeding. It should not be used during pregnancy.
