Documented Uses

• For the treatment of allergic conjunctivitis, vernal conjunctivitis, episcleritis, and epinephrine sensitivity.
• A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.
• Established Pharmacologic Class [EPC] - Corticosteroid
• Mechanisms of Action [MoA] - Corticosteroid Hormone Receptor Agonists
• Medrysone is a Corticosteroid. The mechanism of action of medrysone is as a Corticosteroid Hormone Receptor Agonist.
• QS01B - Antiinflammatory agents
