DRUGS & SUPPLEMENTS
Indications and Usage
Megaplex acetate is indicated for the palliative treatment of advanced carcinoma of the breast or endometrium (i.e., recurrent, inoperable, or metastatic disease). It should not be used in lieu of currently accepted procedures such as surgery, radiation, or chemotherapy.
History of hypersensitivity to Megaplex acetate or any component of the formulation.
Megaplex acetate may cause fetal harm when administered to a pregnant woman. Fertility and reproduction studies with high doses of Megaplex acetate have shown a reversible feminizing effect on some male rat fetuses. There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking (receiving) this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
The use of Megaplex in other types of neoplastic disease is not recommended.
The glucocorticoid activity of Megaplex acetate tablets has not been fully evaluated. Clinical cases of new onset diabetes mellitus, exacerbation of pre-existing diabetes mellitus, and overt Cushing’s syndrome have been reported in association with the chronic use of Megaplex. In addition, clinical cases of adrenal insufficiency have been observed in patients receiving or being withdrawn from chronic Megaplex therapy in the stressed and non-stressed state. Furthermore, adrenocorticotropin (ACTH) stimulation testing has revealed the frequent occurrence of asymptomatic pituitary-adrenal suppression in patients treated with chronic Megaplex therapy. Therefore, the possibility of adrenal insufficiency should be considered in any patient receiving or being withdrawn from chronic Megaplex therapy who presents with symptoms and/or signs suggestive of hypoadrenalism (e.g., hypotension, nausea, vomiting, dizziness, or weakness) in either the stressed or non-stressed state. Laboratory evaluation for adrenal insufficiency and consideration of replacement or stress doses of a rapidly acting glucocorticoid are strongly recommended in such patients. Failure to recognize inhibition of the hypothalamic-pituitary-adrenal axis may result in death. Finally, in patients who are receiving or being withdrawn from chronic Megaplex therapy, consideration should be given to the use of empiric therapy with stress doses of a rapidly acting glucocorticoid in conditions of stress or serious intercurrent illness (eg., surgery, infection).
Close surveillance is indicated for any patient treated for recurrent or metastatic cancer. Use with caution in patients with a history of thromboembolic disease.
Use in Diabetics
Exacerbation of pre-existing diabetes with increased insulin requirements has been reported in association with the use of Megaplex acetate.
Information for the Patients
Patients using Megaplex acetate should receive the following instructions:
Breast malignancies in which estrogen and/or progesterone receptors are positive are more likely to respond to Megaplex.
Carcinogenesis, Mutagenesis, and Impairment of Fertility
Administration of Megaplex acetate to female dogs for up to 7 years is associated with an increased incidence of both benign and malignant tumors of the breast. Comparable studies in rats and studies in monkeys are not associated with an increased incidence of tumors. The relationship of the dog tumors to humans is unknown but should be considered in assessing the benefit-to-risk ratio when prescribing Megaplex acetate and in surveillance of patients on therapy.
Pregnancy Category D
Because of the potential for adverse effects on the newborn, nursing should be discontinued if Megaplex is required for treatment of cancer.
Safety and effectiveness in pediatric patients have not been established.
Insufficient data from clinical studies of Megaplex acetate tablets are available for patients 65 years of age 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.
Megaplex acetate 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.
Weight gain is a frequent side effect of Megaplex. This gain has been associated with increased appetite and is not necessarily associated with fluid retention.
Thromboembolic phenomena including thrombophlebitis and pulmonary embolism have been reported.
Other Adverse Reactions
Heart failure, nausea and vomiting, edema, breakthrough menstrual bleeding, dyspnea, tumor flare (with or without hypercalcemia), hyperglycemia, glucose intolerance, alopecia, hypertension, carpal tunnel syndrome, mood changes, hot flashes, malaise, asthenia, lethargy, sweating and rash.
No serious unexpected side effects have resulted from studies involving Megaplex acetate administered in dosages as high as 1600 mg/day. Oral administration of large, single doses of Megaplex acetate (5 g/kg) did not produce toxic effects in mice. Megaplex acetate has not been tested for dialyzability; however, due to its low solubility it is postulated that this would not be an effective means of treating overdose.
Dosage and Administration
Breast Cancer: 160 mg/day (40 mg q.i.d.).
Endometrial Carcinoma: 40 mg/day to 320 mg/day in divided doses.
At least 2 months of continuous treatment is considered an adequate period for determining the efficacy of Megaplex acetate.
