Hydrocortisone is a synthetic form of cortisol, a corticosteroid hormone produced by the adrenal gland. It is used for its anti-inflammatory and immunosuppressive properties in conditions such as adrenal insufficiency, severe allergies, asthma, and various autoimmune disorders. Hydrocortisone is approved and widely used in clinical practice today.
