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.
Triamcinolone acetonide is a synthetic corticosteroid with potent anti-inflammatory, immunosuppressive, and anti-proliferative effects. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, which reduces prostaglandin and leukotriene synthesis. It also suppresses cytokine production and immune cell migration.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
60 mg (1.5 mL) intramuscularly (deep IM) as a single dose for allergic/ inflammatory conditions; intra-articular or soft tissue injection: 10-40 mg for large joints, 5-25 mg for medium joints, 2.5-10 mg for small joints; intralesional: up to 1 mg per injection site, repeated as needed.

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: 2–4 hours for triamcinolone acetonide; prolonged in hepatic impairment (up to 6–8 hours).
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic metabolism.
Primarily hepatic metabolism followed by renal excretion of inactive metabolites; less than 5% excreted unchanged in urine, with minor biliary/fecal elimination (<2%).
