Adrenal insufficiency: Metabolic failure in hormone production Congenital adrenal hyperplasia.

Rifampicin and anticonvulsant drugs such as phenytoin & Phenobarbital reduce the effectiveness and bioavailability of coicosteroid replacement therapy by inducing steroid metabolizing enzymes in the liver.
