Description: Aminoglutethimide is an anticancer drug that belongs to the family of drugs called nonsteroidal aromatase inhibitors. Aminoglutethimide is used to decrease the production of sex hormones (estrogen in women or testosterone in men) and suppress the growth of tumors that need sex hormones to grow. Aminoglutethimide is marketed under the tradename Cytadren by Novartis around the world. It blocks the production of steroids derived from cholesterol and is clinically used in the treatment of Cushing's syndrome and metastatic breast cancer.

Additional Information

Cytadren inhibits the enzymatic conversion of cholesterol to Δ5-pregnenolone, resulting in a decrease in the production of adrenal glucocorticoids, mineralocorticoids, estrogens, and androgens. Cytadren blocks several other steps in steroid synthesis, including the C-11, C-18, and C-21 hydroxylations and the hydroxylations required for the aromatization of androgens to estrogens, mediated through the binding of Cytadren to cytochrome P-450 complexes. A decrease in adrenal secretion of cortisol is followed by an increased secretion of pituitary adrenocorticotropic hormone (ACTH), which will overcome the blockade of adrenocortical steroid synthesis by Cytadren. The compensatory increase in ACTH secretion can be suppressed by the simultaneous administration of hydrocortisone. Since Cytadren increases the rate of metabolism of dexamethasone but not that of hydrocortisone, the latter is preferred as the adrenal glucocorticoid replacement. Although Cytadren inhibits the synthesis of thyroxine by the thyroid gland, the compensatory increase in thyroid-stimulating hormone (TSH) is frequently of sufficient magnitude to overcome the inhibition of thyroid synthesis due to Cytadren. In spite of an increase in TSH, Cytadren has not been associated with increased prolactin secretion. Note: Cytadren was marketed previously as an anticonvulsant but was withdrawn from marketing for that indication in 1966 because of the effects on the adrenal gland.
Aminoglutethimide is indicated in conjunction with other drugs for the suppression of adrenal function in patients with Cushing's syndrome. It is also a 2nd or 3rd line choice for the treatment of hormone sensitive (estrogen and progesterone) metastatic breast cancer.
Cytadren, aminoglutethimide tablets USP, is an inhibitor of adrenocortical steroid synthesis, available as 250-mg tablets for oral administration. Its chemical name is 3-(4-aminophenyl)-3-ethyl-2,6-piperidinedione.  Aminoglutethimide USP is a fine, white or creamy white, crystalline powder. It is very slightly soluble in water, and readily soluble in most organic solvents. It forms water- soluble salts with strong acids. Its molecular weight is 232.28. Inactive Ingredients. Cellulose compounds, colloidal silicon dioxide, starch, stearic acid, and talc.
Aminoglutethimide is abused by body builders and other steroid users to lower circulating levels of cortisol in the body and prevent muscle loss. Cortisol is catabolic to protein in muscle and effective blockade of P450scc by aminogluthethimide at high doses prevents muscle loss.
