ADVAIR DISKUS 250/50 vs CORTRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators. Salmeterol xinafoate is a long-acting beta2-adrenergic agonist that relaxes bronchial smooth muscle by increasing cyclic AMP.
Cortril (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators and suppression of immune response.
1 inhalation (fluticasone propionate 250 mcg and salmeterol 50 mcg) twice daily, approximately 12 hours apart, via oral inhalation.
Hydrocortisone (Cortril) for adrenal insufficiency: 20-30 mg orally daily divided into two or three doses. For acute conditions, IV or IM hydrocortisone sodium succinate 100 mg every 8 hours.

Fluticasone propionate: 14-17 hours (terminal). Salmeterol: 5.5 hours (terminal). The fluticasone half-life supports twice-daily dosing with potential accumulation.
Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
Fluticasone propionate: <5% renal (as metabolites), majority biliary/fecal. Salmeterol: 57% renal (as metabolites), 30% fecal.
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
