Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
Prednisolone is a glucocorticoid receptor agonist that binds to the intracellular glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production (e.g., IL-1, IL-6, TNF-alpha). It also suppresses immune responses by reducing lymphocyte proliferation and activity.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
Oral: 5-60 mg/day as a single dose or divided doses; adjust based on condition and response.

The terminal elimination half-life of mometasone furoate is approximately 5.8 hours. This short half-life supports once-daily dosing for intranasal use, but systemic accumulation is minimal with topical administration.
2.5–3.5 hours (terminal) in children; clinical context: requires multiple daily doses for sustained effect.
Mometasone furoate is predominantly eliminated via biliary/fecal excretion. After intravenous administration, approximately 74% of the dose is recovered in feces and about 8% in urine. The drug undergoes extensive hepatic metabolism, and metabolites are excreted primarily in bile.
Renal: ~80% as metabolites (mainly glucuronides and sulfates) and <5% unchanged; fecal: ~15%.
