Active clinical trials for "Rhinitis, Allergic"

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 was to test the effectiveness and safety of desloratadine (Aerius) syrup in children with hayfever with or without asthma. Patients took desloratadine syrup once a day for 28 days. Once a week, the doctor measured the patient's hayfever symptoms. The doctor also rated how much relief the patient got from treatment and recorded any side effects.

This study will evaluate the efficacy and safety of ragweed sublingual tablet (SCH 39641/MK-3641) compared with placebo in participants with ragweed-induced rhinoconjunctivitis over a one-year period. It is expected that ragweed allergic participants on one of the active arms of the trial will have decreased allergic rhinoconjunctivitis symptoms and require less allergy rescue medications during ragweed pollen season.

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.

The objective of this study is to assess the efficacy and safety of cluster immunotherapy with highly polymerized allergen extracts.

The prevalence of allergic rhinitis is high and appears to be rising worldwide. Therefore, it is important and necessary to understand and visualize therapy effects on this disease. In this study we will demonstrate the effect of levocetirizine on nasal cavity dimensions by assessing not only standard nasal flow diagnostics such as rhinomanometry and acoustic rhinometry, but supplement exami¬nation procedures with long-term rhinometry and magnetic resonance imaging (MRI). With the aid of a virtual model and computer fluid dynamics, we are able to simulate nasal air flow and provide three-dimensional visualization of the computed flow. In previous trials ([Bachert], [deBlic], [Day] and [Deruaz]) it has been shown that allergic symptoms, especially nasal congestion, diminish significantly under treatment with levocetirizine. We will demonstrate this anti-obstructive effect by comparing the reaction to nasal allergen challenge before and after four-week treatment with levocetirizine.

Up to 40% of patients with asthma have allergic rhinitis and treatment of nasal airway inflammation with topical steroids improves the twitchiness of the airways (hyperresponsiveness) and overall asthma control. The use of inhaled corticosteroids reduces symptoms, severity of asthma attacks, improves quality of life, and reduces asthma related deaths. Similarly, treatment of rhinitis with nasal steroids reduces symptoms and improves quality of life. While there is evidence that combined treatment of the nose and the lungs with topical steroids improves symptoms and underlying inflammation, it is unclear whether such control can be achieved using a smaller dose of inhaled steroid in combination with nasal steroid. It is therefore the intention of this study to evaluate if combination steroid therapy (nose and lungs) has a steroid sparing effect in patients with asthma and rhinitis using sensitive markers of airway inflammation.

The purpose of this study is to evaluate the effect of as-needed treatment with nasal carbon dioxide in patients with Seasonal Allergic Rhinitis symptoms.

The purpose of the study is to determine whether VAK694 when combined with subcutaneous immunotherapy leads to long term immune tolerance to allergen in individuals with seasonal allergic rhinitis.

To assess the efficacy of the study product Noex in the treatment of allergic rhinitis by means of the Nasal Index Score (NIS) after 4 weeks of treatment with the drug.
