Drug-related causes

  • Ketoconazole inhibits the adrenal cytochrome P450 steroidogenic enzymes.

  • Aminoglutethimide blocks the early conversion of cholesterol to pregnenolone by inhibiting the 20,22-desmolase enzyme.

  • Mitotane (O,P'-DDD) blocks adrenal mitochondrial steroid biosynthesis.

  • Busulphan, etomidate, and trilostane inhibit or interfere with adrenal steroid biosynthesis.

  • Methadone, perhaps by depleting pituitary ACTH, may cause secondary adrenocortical insufficiency in some patients. [37]
