Megestrol suspension is being used for treating lack of appetite, malnutrition, and extreme weight loss in patients with acquired immune deficiency syndrome (AIDS). Megestrol should not be used to avoid loss of appetite and extreme weight loss in patients who have not yet developed. Megestrol is a man-made form of a human hormone called progesterone.

Megestrol is a type of hormonal therapy. Hormones are chemical compounds produced by glands in the body that enter the bloodstream and cause effects in other tissues. (For example, testosterone hormone produced in the testicles is responsible for male characteristics such as deeper voice and increased body hair). Used as a hormone therapy to treat cancer is focused on the finding that receptors for particular hormones are required for cell development.
Hormone therapy works by preventing the development of a certain hormone, blocking hormone receptors, or substituting chemically identical agents for an active hormone that cannot be used by a tumor cell. The various forms of hormone therapy are classified by their function and/or the type of hormone that is affected.
Megestrol is known as a progestin (a man-made form of the hormone progesterone). It has properties that interact with the normal oestrogen cycle.This interferes with the stimulation of cell growth in oestrogen-dependent tumor cells. It is also believed to have a direct effect on the lining of the uterine wall (endometrium).
The side effect of megestrol was weight gain. The exact mechanism of this effect is unknown, but the results contribute to an increase in body fat. Taking advantage of this side effect, megestrol has been researched and used to treat extreme loss of appetite (anorexia), loss of muscle (cachexia) and loss of weight. associate with cancer and AIDS
