Common NameAminoglutethimide
ClassSmall Molecule
DescriptionAn aromatase inhibitor that produces a state of 'medical' adrenalectomy by blocking the production of adrenal steroids. It also blocks the conversion of androgens to estrogens. Aminoglutethimide has been used in the treatment of advanced breast and prostate cancer. It was formerly used for its weak anticonvulsant properties.

Toxicity Profile
Route of ExposureRapidly and completely absorbed from gastrointestinal tract. The bioavailability of tablets is equivalent to equal doses given as a solution.
Mechanism of ToxicityAminoglutethimide reduces the production of D5-pregnenolone and 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 aminoglutethimide to cytochrome P-450 complexes. Specifically, the drug binds to and inhibits aromatase which is essential for the generation of estrogens from androstenedione and testosterone. 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 aminoglutethimide. The compensatory increase in ACTH secretion can be suppressed by the simultaneous administration of hydrocortisone. Since aminoglutethimide increases the rate of metabolism of dexamethasone but not that of hydrocortisone, the latter is preferred as the adrenal glucocorticoid replacement. Although aminoglutethimide 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 aminoglutethimide. In spite of an increase in TSH, aminoglutethimide has not been associated with increased prolactin secretion.
MetabolismHepatic. 34-54% of the administered dose is excreted in the urine as unchanged drug during the first 48 hours, and an additional fraction as an N-acetyl derivative. Route of Elimination: After ingestion of a single oral dose, 34%-54% is excreted in the urine as unchanged drug during the first 48 hours, and an additional fraction as the N-acetyl derivative. Half Life: 12.5 ± 1.6 hours
Toxicity ValuesOral LD50s (mg/kg): rats, 1800; dogs, >100. Intravenous LD50s (mg/kg): rats, 156; dogs, >100.
