Efficacy and Safety of Mometasone Furoate Nasal Spray in Treating Nasal Polyposis: A Systematic Review and Meta-Analysis.

Topical and systemic corticosteroids are the most effective medical treatment for nasal polyps, this study aims to systematically explore the efficacy and safety of mometasone furoate (MTF) for patients with nasal polyps (NP). The systematic review was conducted following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines and was registered in The International Prospective Register of Systematic Reviews (PROSPERO.) Data were extracted from relevant and appropriate randomized controlled trials (RCTs) of synthetic corticosteroids for patients with nasal polyps from PubMed, Google Scholar, Web of Science, and Science Direct, encompassing studies published between January 1995 and July 2024. A total of 834 publications were found based on the search criteria. Around 1,710 patients were reviewed for this systematic review from full full-text articles. Primary outcomes include a change in polyp size (assessed by total polyp size scores), and nasal congestion (assessed by measuring changes from baseline in nasal congestion/obstruction scores). secondary outcomes consist of nasal symptoms, including loss of smell, anterior rhinorrhea, postnasal drip, quality of life outcomes, and adverse events. Mometasone furoate nasal spray (MFNS) significantly improves nasal symptoms and reduces nasal polyp size for patients with nasal polyps (NP).
