Antileukotrienes These agents have been advocated as adjuncts to INS for the treatment of CRSwNP.Modest benefit has been noted after 1 3 months of montelukast or the 5 lipoxygenase selleck compound inhibitor zileuton in studies lacking pla cebo control.However,placebo controlled studies have mostly failed to demonstrate benefit of montelukast for nasal polyposis,and zileuton has not been subjected to a placebo controlled trial.Adjunctive therapies A Cochrane review Inhibitors,Modulators,Libraries of 8 studies using various forms of sa line sprays and irrigation performed 1 4 times daily found that intranasal saline is an effective adjunctive treatment for CRS.Saline irrigation provides a subjective sense of freshening,rinses away allergens and irritants,removes secretions,improves mucociliary clearance,and reduces postnasal drainage.
An isotonic concentration is generally preferred to hypertonic saline.Intranasal lavage can be performed with over the counter devices Inhibitors,Modulators,Libraries such as squeeze bottles,sy ringes and pots.Appropriate cleaning is required to avoid contamination of the device.The evidence does not currently support the use of mucolytics,oral decongestants,or protracted adminis tration of intranasal decongestants for CRS.However,therapies of associated conditions may aid the manage ment of CRS.These include antihistamines,environ mental control to reduce problematic exposures and allergen immunotherapy for patients Inhibitors,Modulators,Libraries with allergic rhin itis,and H2 antagonists and proton pump inhibitors for patients with laryngopharyngeal reflux.
For patients with aspirin exacerbated respiratory disease,aspirin desensitization followed by daily aspirin therapy has been reported as beneficial for control of nasal polyps,although placebo controlled trials have not been con ducted.CRS Pharmacotherapy There is a relative paucity of controlled studies for this Inhibitors,Modulators,Libraries indication.The design and interpretation of CRS clinical trials has been hindered by the heterogeneity of the dis ease,a deficiency of uniform definitions for disease subtypes,incomplete understanding of the underlying pathologies,and a lack of useful Inhibitors,Modulators,Libraries and standardized clin ical and laboratory endpoints to measure response to therapy.The most comprehensive treatment recom mendations for CRS are put forth in the EPOS consen sus document.Recommendations are categorized GSI-IX into 3 major subtypes,CRSsNP,CRSwNP and AFRS.Recommendations are also stratified according to disease severity,using a visual analogue scale of 0 to 10.CRSsNP 1.Initially intranasal saline and INS 2.If after 3 months not improved,perform culture,institute long term macrolide therapy 3.If improved,continue intranasal saline and INS with without macrolide therapy 4.
