BETAPAR vs TARPEYO
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.
TARPEYO (budesonide) is a corticosteroid with anti-inflammatory activity. It acts by binding to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines and immune cell activation, thereby reducing proteinuria in IgA nephropathy.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
16 mg/kg intravenously once daily on Days 1-5 of each 28-day cycle.

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 is approximately 27.3 hours (range 21-36 hours) in patients with IgA nephropathy. This supports once-weekly subcutaneous dosing without dose adjustment over the dosing interval.
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, with <1% excreted unchanged in urine and <1% in feces. Elimination is predominantly via biliary excretion of metabolites into feces, accounting for >90% of total clearance.
