Betamethasone is a potent synthetic glucocorticoid corticosteroid used for its anti-inflammatory and immunosuppressive effects. It is widely approved for the treatment of various inflammatory, allergic, and autoimmune conditions, as well as for fetal lung maturation in preterm labor. Betamethasone is available in topical, oral, parenteral, and intramuscular formulations.
Pharmacokinetics
Pharmacokinetic parameters estimated for adult healthy volunteers receiving a single oral dose of betamethasone.
