2. How Does Megestrol acetate work?aasraw


Megestrol acetate is a type of hormone therapy. Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues. (For example, the hormone testosterone made in the testicles is responsible for male characteristics such as deepening voice and increased body hair). The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells.  Hormone therapies work by; stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell.  The different types of hormone therapies are categorized by their function and/or the type of hormone that is effected.
Megestrol acetate is a progestin (a man-made form of the hormone progesterone).  It has properties that interfere with the normal estrogen cycle.  This interferes with the stimulation of cell growth in estrogen dependent tumor cells.  There is also thought to be some direct effect on the lining of the uterine wall (endometrium).
A side effect of Megestrol acetate has been weight gain.  The exact mechanism of this effect is unclear, however the effects lead to an increase in body fat.  Taking advantage of this side effect, Megestrol acetate has been studied and used to treat severe appetite loss (anorexia), muscle wasting (cachexia) and weight loss associated with cancer and AIDS.

6. Use Megestrol acetate Powder in specific populationsaasraw



Pregnancy Category X [see Warnings and Precautions (5.2)]. No adequate animal teratology information is available at clinically relevant doses. Pregnant rats treated with low doses of Megestrol acetate powder (0.02-fold the recommended clinical dose) resulted in a reduction in fetal weight and number of live births, and feminization of male fetuses.

 Nursing Mothers

Because of the potential for adverse effects on the newborn, nursing should be discontinued if Megestrol acetate powder is required.

 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

 Geriatric Use

Clinical studies of Megestrol acetate powder in the treatment of anorexia, cachexia, or an unexplained significant weight loss in patients with AIDS did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Megestrol acetate powder  is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

 Use in Women

Megestrol acetate powder has had limited use in HIV infected women. All 10 women in the clinical trials reported breakthrough bleeding. Megestrol acetate powder is a progesterone derivative, which may induce vaginal bleeding in women.

9. Megestrol Acetate Use for Weight Gain Should Be Carefully Consideredaasraw

Megestrol acetate (595-33-5) is a progestational agent with a powerful effect on appetite. It was initially used as a contraceptive agent; however, the common side effect of weight gain led to its current use as an orexigenic agent. Administration of MA results in substantial increases in appetite and body weight in patients with HIV-associated wasting and in those with cancer. MA is currently Food and Drug Administration (FDA) approved for HIV-associated weight loss. In addition, both in healthy, community-dwelling older individuals and elderly people residing in long-term care facilities, the use of MA results in a robust increase in body weight. The use of orexigenic agents such as MA in these settings is appropriate because involuntary weight loss has been associated with increased mortality. Indeed, MA has a greater effect on body weight and appetite than other orexigenic agents such as dronabinol and eicospentaenoic acid. However, in older people and patients with cancer or renal failure, fat is the principal or the only constituent of weight gain, with little accrual of skeletal muscle or other components of fat-free mass. Among the many side effects of the use of MA, suppression of testosterone and estrogen production is prominent. Before the common use of other effective androgen suppressive treatments (flutamide, bicalutamide) in men with prostate cancer, MA was commonly used in this setting. Indeed, in older men, use of MA results in near-castrate levels of testosterone. MA has also been used to suppress estrogen levels in women with breast cancer.
The study published this month in JCEM examined the combined effects of testosterone and MA on the composition of weight gain in patients with HIV-associated wasting. This study demonstrates, once again, that MA has a substantial effect on appetite and body weight, with fat gain the principal component of the increase in body weight. However, fat-free mass was also increased along with total body weight in this trial, similar to a previous examination of the effect of MA on weight gain in patients with HIV-associated weight loss. Mulligan et al.showed that testosterone was suppressed, and testosterone replacement had no effect on the composition of the weight gain; furthermore, MA administration resulted in decreased libido. This suppressive effect of MA on testosterone production and in blocking the effects of testosterone on lean body mass accrual should be carefully considered before using MA in this patient population. Loss of lean mass in HIV patients is strongly linked to low androgen levels.
A number of unanswered questions concerning the effects of MA remain. Its use must be carefully considered and carefully managed. If an improvement in appetite and a gain in fat mass are desirable goals in the management of cachexia or involuntary weight loss, MA remains one of the most potent orexigenic agents currently available. Its use must be weighed against the potential for adrenal suppression and suppression of androgen production. Because of its antiandrogen properties, the antianabolic effects of MA are not ameliorated by testosterone administration.
