Mestrolyst

Mestrolyst contains Megestrol acetate, a synthetic progestational agent primarily used in the treatment of certain cancers and as an appetite stimulant. It plays a significant role in managing weight loss and cachexia in patients with AIDS or cancer.

Uses

• Treatment of advanced breast cancer

• Treatment of advanced endometrial cancer

• Management of anorexia, cachexia, or significant weight loss in patients with AIDS or cancer

Mechanism of Action

Megestrol acetate works by inhibiting the release of gonadotropins from the pituitary gland, resulting in decreased estrogen production, which is beneficial in hormone-sensitive cancers. Additionally, it has appetite-stimulating properties.
