A-METHAPRED vs BETAMETHASONE DIPROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines, prostaglandins, and leukotrienes. It also induces lipocortin synthesis, inhibits phospholipase A2, and reduces immune cell activity.
Betamethasone dipropionate is a glucocorticoid receptor agonist that binds to cytosolic glucocorticoid receptors, leading to modulation of gene transcription. It suppresses pro-inflammatory cytokines (e.g., IL-1, IL-2, TNF-α), inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes mast cells.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
Apply topically as 0.05% cream, ointment, or lotion to affected area once or twice daily. Maximum: 45 g/week.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life: 6-8 hours (parenteral); clinically, duration of adrenal suppression may extend beyond this.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Renal, ~75% as conjugated metabolites; biliary/fecal, ~25%.
