What is megestrol acetate and its primary function?

• A. A natural estrogen that reduces appetite
• B. A synthetic progestational agent that promotes weight gain and stimulates appetite
• C. A chemotherapy agent that reduces tumor size
• D. A mineral supplement used to treat anemia

Answer: (B)

Megestrol acetate is a synthetic progestin used as an appetite stimulant to promote weight gain in patients with anorexia-cachexia. Its primary function is to increase appetite and support increased caloric intake, helping improve body weight in debilitated individuals. It is not a natural estrogen, a chemotherapy agent, or a mineral supplement. While useful when oral intake is limited, it can carry risks such as blood clots, edema, glucose intolerance, and potential liver function changes, so monitoring is important.
