Effect of Topical Nasal Decongestants on Nasal Peak Flow Rates in Adults Suffering from Acute Sinusitis

Abstract

INTRODUCTION In this research we study the effect of Nasal decongestant Xylometazoline 0.1% solution on Serial measurements of Nasal peak flow rates in a cohort of patients who were suffering from Acute Sinusitis. CASE SERIES A population of 90 patients were chosen from our regular Out-patient clinics who were suffering from Acute Sinusitis based on a Clinical diagnostic criterion. A baseline Nasal peak Flowmetry was done before and this was followed by common Decongestant Xylometazoline 0.1% solution spray application, followed by serial readings of Nasal peak Flowmetry done after 10 minutes, 25 minutes, 60 minutes, 120 minutes,240 minutes and 360 was taken then plotted and analysed. DISCUSSION From the A.U.C Curves it can be inferred that Maximum decongestant action of Xylometazoline 0.1% solution is seen 1 hour after application and the raise in decongestant reaches a plateau by 2 hours. Readings remain elevated from baseline well 6 hours post decongestion. CONCLUSION Patients who are prescribed Xylometazoline 0.1% solution are advised that maximum relief from congestion would be obtained around 1 to 2 hours after application and hence effect would decrease. Surgeons who use Xylometazoline 0.1% solution for nasal packing must proceed with the Surgery within 1 hour of application of the pack to obtain maximum hemostatic and decongestant benefit of this drug.
