Hydrocortisone is a corticosteroid hormone (glucocorticoid) used to treat inflammation, allergic reactions, adrenal insufficiency (such as Addison's disease), and certain eye disorders. It is commonly approved and used today both systemically and in topical or ophthalmic preparations.
Pharmacokinetics
Pharmacokinetic parameters estimated in healthy adult subjects following oral administration.
