MOMETASONE FUROATE vs NASACORT HFA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mometasone furoate is a corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. It binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, reduced arachidonic acid release, and decreased synthesis of prostaglandins and leukotrienes. It also suppresses cytokines, chemokines, and adhesion molecules involved in inflammation.
Corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators (e.g., cytokines, prostaglandins) and reducing nasal inflammation.
Inhaled: 110-880 mcg twice daily; Intranasal: 2 sprays (50 mcg/spray) per nostril once daily; Topical: Apply thin film to affected area once daily.
55 mcg (1 spray) per nostril once daily; may increase to 110 mcg (2 sprays) per nostril once daily if needed. Maximum 440 mcg/day total.

The terminal elimination half-life is approximately 5.8 hours (range 4.5–7.5 hours) following intravenous administration; after intranasal or inhalation use, the effective half-life supporting once-daily dosing is derived from receptor binding and local tissue retention.
Terminal elimination half-life is approximately 3.5 hours following intranasal administration, reflecting slow systemic absorption and prolonged local retention.
Mometasone furoate is extensively metabolized in the liver; less than 1% of the dose is excreted unchanged in urine. The metabolites are primarily excreted in feces (~74%) via biliary elimination, with renal excretion accounting for approximately 8–10%.
