Generic name

MEGESTROL ACETATE

Indications

Megestrol Acetate is used in anorexia, cachexia or a significant weight loss. Megestrol Acetate is also indicated for the palliative treatment of advanced carcinoma of the breast (i.e. recurrent, inoperable or metastatic diseases). It should not be used in lieu of currently accepted procedures such as surgery, radiation or chemotherapy.

Therapeutic Class

Hormonal Chemotherapy

Pharmacology

Megestrol Acetate is a synthetic progestational anticancer drug. It may work by interfering with the hormone balance in the body, which may stop the cancer growing. It may also act directly on cancer cells so that they can't grow. Moreover, Megestrol Acetate causes weight gain by increasing the fat and body cell mass and this weight gain is associated with increased appetite. Therefore this drug is used as an appetizer for the cancer patients suffering from anorexia, significant weight loss or cachexia.

Dosage & Administration

For the following indications, at least two months of continuous treatment is considered an adequate period for determining the efficacy of megestrol acetate tablets. For palliative or adjunctive treatment of breast carcinoma: 160 mg or 125 mg/m<sup>2</sup> daily (40 mg q.i.d. or 160 mg q.d.) For endometrial carcinoma: 80 - 320 mg or 62.5 - 250 mg/m<sup>2</sup> daily in divided doses (40 - 80 mg one to four times daily or one to two 160 mg tablets daily). For palliative treatment of hormone responsive advanced (Stage D2) carcinoma of the prostate: 120 mg (93.8 mg/m<sup>2</sup>) as a single daily dose in combination with diethylstilbestrol tablet, 0.1 mg. For anorexia, cachexia, or significant weight loss in patients with cancer: usual adult dose: 400 to 800 mg as a single daily dose. The recommended adult initial dosage of megestrol acetate oral suspension is 625 mg/day (5 mL/day or one teaspoon daily). Shake container well before using
