Active clinical trials for "Rhinitis"

RV568 is being developed for the treatment of diseases such as asthma, COPD and allergic rhinitis (e.g. hayfever). The main aim of this study is to investigate whether RV568 ameliorates the nasal symptoms to low doses of grass pollen in healthy subjects with seasonal allergic rhinitis.

The loratadine-pseudoephedrine combination has proven to be more effective than the use of these individual components. This prospective, randomized, double-blind and paralel study, in which patients with perennial allergic rhinitis receive one of loratadine + pseudoephedrine association drug for treatment of signs and symptoms during 4 weeks.

This is a 14-day, randomized, placebo-controlled, parallel group, masked clinical trial of oral guaifenesin for the therapy of Chronic Rhinitis (CRS) in 36 children between the ages of 7 and 18 years. The study investigates the effectiveness of guaifenesin in the relief of nasal symptoms in children with CRS using the sinonasal 5 survey (SN-5) in comparison to nasal airway volume, and biophysical properties of nasal secretion. The investigators hypothesize that Guaifenesin use over a period of 14 days improves subjective nasal complaints in pediatric patients with chronic rhinitis and nasal congestion, as measured by the SN-5 survey compared to use of placebo. There will be an observed improvement in nasal volume and cross-sectional area following use of guaifenesin, and nasal secretions will have more favorable mucociliary and sneeze clearability compared to use of placebo.

The term idiopathic rhinitis (IR) is used in this study to describe a patient group with following characteristics: patients with complaints of nasal obstruction, sneezing and/or rhinorrhea for a period of over 1 year, which cannot be attributed to allergy, nasal or paranasal infection, anatomical disorders, pregnancy or lactation and/or systemic disorders. These patients are non-smokers and do not use medication affecting nasal function. They have no beneficial effect of intranasal steroid spray (INS) treatment. The population incidence of IR is estimated to be as high as 10%. The pathophysiology of IR is largely unknown. Several hypotheses have been put forward. In general it is assumed that neurogenic mechanisms play an important role. Neuropeptides like CGRP, SP, NKA/B, NPY, NGF are released from afferent neurons in the nasal mucosa after activation by unspecific stimuli and can be responsible for the symptoms of IR. For this group of IR-patients, there is until now only one treatment option: intranasal capsaicin application. Capsaicin, the pungent agent in hot pepper, is supposed to exert its' therapeutic effect via degeneration or desensitization effect on the afferent C-fibers. The hypothesis is that nasal capsaicin treatment reduces neurogenic inflammation and reduces in that way nasal symptoms.

This study compared the safety and efficacy of a generic fluticasone furoate (Lek Pharmaceuticals) nasal spray to the reference listed drug in the treatment of seasonal allergic rhinitis. Additionally both the test and the reference formulations were tested for superiority against a placebo nasal spray.

This study will investigate the effectiveness of desloratadine in treating subjects with allergic rhinitis who meet the criteria for persistent allergic rhinitis (PER)

This is a randomized, double blind, active and placebo controlled, 4 way crossover study in patients with seasonal allergic rhinitis. Patients will receive a single dose of bilastine 20 mg, Cetirizine 10 mg, Fexofenadine 120 mg, and placebo in the Vienna Challenge Chamber.

This study is designed to assess the effectiveness of mometasone furoate nasal spay (MFNS) once daily (QD) compared with placebo in subjects with seasonal allergic rhinitis (SAR) in reducing the total nasal symptom score and the total ocular symptom score.

The objective of the study is to evaluate the efficacy and tolerability of Bilastine 20 mg, compared to Cetirizine and placebo for the treatment of seasonal allergic rhinitis.

The objective of this trial is to evaluate the clinical effectiveness of the administration of a depigmented and polymerized allergen extract of Phleum pratense in the rhinoconjunctivitis and/or asthma of slight or moderate intensity, due to allergy to grass pollen.
