Hydrocortisone Acetate
Hydrocortisone Acetate is a synthetic corticosteroid ester derived from hydrocortisone (cortisol). It is a white to off-white crystalline powder, practically insoluble in water but soluble in alcohol and acetone. This compound exhibits potent anti-inflammatory, immunosuppressive, and anti-allergic properties, making it widely used in pharmaceutical and dermatological formulations. Hydrocortisone Acetate acts by modulating gene expression to reduce the production of inflammatory mediators, thereby alleviating symptoms in various inflammatory and autoimmune conditions.
