ASMANEX TWISTHALER vs CORTENEMA
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.
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.
Inhalation: 1-2 inhalations twice daily (morning and evening). Typical adult dose: 200-400 mcg twice daily. Maximum: 800 mcg/day.
One enema (100 mg hydrocortisone in 60 mL) administered rectally once daily, preferably at bedtime, for 21 days or until clinical response.

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