Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-2 adrenergic receptor agonist that stimulates adenylyl cyclase, increasing cAMP levels, leading to bronchodilation.
Hydrocortisone acetate is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It exerts anti-inflammatory, immunosuppressive, and vasoconstrictive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
Hydrocortisone acetate is typically administered as a topical, intra-articular, intradermal, or rectal preparation. For intra-articular use, adult dose: 5-50 mg (depending on joint size) every 1-2 weeks. For rectal use, 25 mg (one suppository) twice daily or 1 application of foam or enema (10% or 1% respectively) once or twice daily. For intradermal injection, 1-2 mL (25 mg/mL) into lesion every 1-2 weeks. Note: Systemic dosing is not applicable as it is not used for systemic effects due to low bioavailability.

Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged to 10-20 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: 1-2 hours for endogenous hydrocortisone; with acetate ester, extended to ~2-4 hours due to slower absorption and hydrolysis. Clinical context: Duration of action exceeds half-life due to intracellular receptor binding.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic metabolism.
Renal: ~80% as metabolites (glucuronide and sulfate conjugates) and <1% unchanged; fecal: <5% via biliary elimination.
