ASMANEX TWISTHALER vs DEXASPORIN
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.
Dexasporin is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of pro-inflammatory mediators such as prostaglandins and leukotrienes.
Inhalation: 1-2 inhalations twice daily (morning and evening). Typical adult dose: 200-400 mcg twice daily. Maximum: 800 mcg/day.
1 to 2 mg/kg intramuscular or intravenous 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.
3-4 hours (prolonged to 10-15 hours in renal impairment; monitor CrCl <30 mL/min)
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 excretion (80-90% unchanged), biliary/fecal (10-20%)
