Hydrocortisone

 

(17-hydroxycorticosterone, cortisol), one of the glucocorticoids; a hormone formed in the adrenal cortex and predominantly regulating carbohydrate metabolism. The human adrenal glands secrete from 5 to 30 mg of hydrocortisone per day, although formation of hydrocortisone may increase five times under conditions of stress or upon introduction of adrenocorticotropic hormone.

Hydrocortisone is used in medical practice as a hormonal preparation that exerts an anti-inflammatory and antiallergic effect. Hydrocortisone (and hydrocortisone acetate in the form of a suspension) is prescribed for the treatment of rheumatism, bronchial asthma, leukemia, and endocrine and other diseases; it is used locally (most often in the form of a cream) for eczema, neurodermatitis, and eye diseases.
