Betamethasone is a corticosteroid with mainly glucocorticoid activity. It prevents and controls inflammation by controlling the rate of protein synthesis, depressing the migration of polymorphonuclear leukocytes and fibroblasts, and reversing capillary permeability and lysosomal stabilisation. Lidocaine: Amide-type local anesthetic; reversibly block the initiation and conduction of nerve impulses by interfering with the flux of sodium ions though the neuronal membrane. Phenylephrine: Alpha adrenergic agonist; elicits localized vasoconstriction and decreases inflammation .
