DRUG INTERACTION Betamethasone is known to interact with other drugs like amphotericin B, carbamazepine, lofexidine, metyrosine, oxandrolone, perindopril, phenytoin (Na), rifampicin. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required. MECHANISM OF ACTION Betamethasone is a glucocorticoid receptor agonist. This leads to changes in genetic expression once this complex binds to the GRE. The antiinflammatory actions of corticosteroids are thought to involve lipocortins, phospholipase A2 inhibitory proteins which, through inhibits arachidonic acid, control the biosynthesis of prostaglandins and leukotrienes.
