Hydrocortisone is a glucocorticoid hormone used as an anti-inflammatory and immunosuppressant agent. It is a synthetic form of cortisol and is widely used in the treatment of adrenal insufficiency (such as Addison's disease), severe allergies, asthma, and rheumatoid arthritis. Hydrocortisone is approved and commonly used in clinical practice both as oral and intravenous formulations.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult volunteers after single oral dose administration.
