BETAPAR vs CORTENEMA
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.
Corticosteroid that binds to the glucocorticoid receptor, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, decrease cytokine production, and suppress inflammatory cell migration and activation in the colonic mucosa.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.

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).
1.8-3.5 hours (plasma); due to rectal administration and low systemic absorption, clinical effects persist longer than plasma levels suggest
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 renal excretion of inactive metabolites; <5% unchanged in urine; biliary/fecal elimination of metabolites accounts for ~80%
