Active clinical trials for "Rhinitis, Allergic"

The study objective is to investigate the efficacy of levocetirizine in reducing symptoms associated with seasonal allergic rhinitis and in improving rhinitis-related Quality of Life

This is a single-centre, randomised, double-blind, four-period, incomplete block, crossover study, with 8 days repeat dosing of intranasal Fluticasone Propionate (25, 50, 100, 200ug) and/or placebo in the Vienna Challenge Chamber in subjects with allergic rhinitis.

MAGNA intends to show that the combination of pseudoephedrine, chlorpheniramine, plus a small amount of belladonna alkaloid is a comprehensive, safe and effective twice daily (BID) drug treatment for seasonal allergic rhinitis (SAR) patients with post-nasal drip (PND). The phase 1 single-dose trial will consist of 21 subjects: 1) to gather pharmacodynamic measurements and blood levels of active ingredients over 12 hours; 2) To report subjective scores by subjects rating efficacy of single dose of STAHIST; 3) To report any side effects or adverse drug reactions and rate the severity of incidence.

The purpose of this study is to determine if two allergy medications (azelastine and fluticasone) are more effective than placebo or either medication alone (azelastine or fluticasone)
