Applications & Uses
Uses
Hormone drugs.It is mainly used for anti-inflammatory and anti-allergic. It is suitable for rheumatoid arthritis and various skin diseases. Betamethasone role is similiar to dexamethasone, its anti-inflammatory effect is stronger than dexamethasone, triamcinolone, hydrocortisone and it has few side effects.
Description
Shortly after the introduction of dexamethasone, betamethasone, which differs from dexamethasone only in configuration of the 16-methyl group, was made available for the treatment of rheumatic diseases and dermatologic disorders. This analogue, which contains a 16β-methyl group, has received sufficient clinical trial examination to indicate that it is as effective as dexamethasone or, perhaps, even slightly more active. Although this drug has been reported to be less toxic than other steroids, some clinical investigators suggest that it is best used for short-term therapy.
Description
Betamethasone is a synthetic corticosteroid. Like other corticosteroids, betamethasone has anti-inflammatory actions. Betamethasone also accelerates fetal lung maturation and has been used to decrease neonatal mortality and morbidity in infants born before 34 weeks of gestation.
Uses
glucocorticoid, antiinflammatory
Uses
anti-inflammatory, immunosuppressive
Uses
Betamethasone is a glucocorticoid used as an anti-inflammatory agent.
