ASMANEX TWISTHALER vs CORTRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators (e.g., cytokines, chemokines, adhesion molecules) and suppression of inflammatory cell migration and activation in the airways.
Cortril (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators and suppression of immune response.
Inhalation: 1-2 inhalations twice daily (morning and evening). Typical adult dose: 200-400 mcg twice daily. Maximum: 800 mcg/day.
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.

The terminal elimination half-life of mometasone furoate following inhalation via ASMANEX TWISTHALER is approximately 5 hours (range 4–6 hours) in patients with asthma. This relatively short half-life supports twice-daily or once-daily dosing with sustained clinical effect due to prolonged local retention in the lungs.
Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
Following oral inhalation, the absorbed fraction of mometasone furoate is extensively metabolized in the liver via CYP3A4. Unchanged drug and metabolites are excreted primarily in the feces via biliary elimination (approximately 74% of a single oral dose) and to a minor extent in the urine (approximately 8%). For inhaled doses, renal excretion of unchanged drug is negligible (<1% of administered dose).
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
