Active clinical trials for "Rhinitis, Allergic"

The purpose of this study is to help us to a better understanding of how nose and eye symptoms are related in patients with allergies.

The purpose of this study is to see whether ASP-1001 when given as a nasal spray is safe and can reduce the signs and symptoms of allergic rhinitis (hayfever) following nasal challenge with antigen.

The purpose of this study is to determine whether cetirizine (zyrtec), levocetirizine (xyzal), and placebo differ in the degree of sedation they produce and their relief of allergy symptoms.

Birch pollen allergy is one of the most common forms of respiratory allergy in the Nordic countries. Treatment consists of antihistamine use. Specific probiotic strains have been observed to modulate the immune system. Since the body has a common mucosal immune system; it was hypothesised that consumption of probiotics may affect also the respiratory mucosal immune response and hence affect respiratory allergy. Earlier studies with probiotics had been unable to show improvements in adults with pollen allergy. It was therefore hypothesised that children, who's immune system is not yet fully developed, might be better targets.

The trial will be conducted as a prospective, randomized, multinational, multicenter, double-blind, placebo and active controlled trial in 4 parallel-groups of patients suffering from seasonal allergic rhinitis.

This study will examine dose ranging characteristics of bepotastine besilate nasal spray compared to placebo nasal spray in 600 male or female subjects 12 years of age and older with active seasonal allergic rhinitis (SAR) and a demonstrated history of allergic sensitivity to Mountain Cedar pollen for at least 2 years prior to the study.

In this study researchers want to learn how quickly patients suffering from allergic rhinitis (also known as hay fever) can expect symptom relief after using Azelastine Hydrochloride 0.15% Nasal Spray. This study plans to enrol about 80 male or female participants in the age of 18 to 65 years suffering from an allergic rhinitis to ragweed pollen for at least 2 years. In a first phase participants will be exposed to ragweed pollen in a special study room to ensure they will be adequately symptomatic when they progress into the treatment phase of the study. In a second phase study participants will be divided in 2 groups. After exposure to ragweed pollen one group will receive Azelastine Hydrochloride 0.15% Nasal Spray and the other group will receive placebo (a nasal spray which does not contain any active drug substance). In the third phase of study the treatment will be switched: participants who received in the previous study Azelastine Hydrochloride 0.15% Nasal Spray will receive the nasal spray without any active drug substance and the other group will receive Azelastine Hydrochloride 0.15% Nasal Spray. During the second and third study phase the researchers will examine thoroughly over 4 hours the change of nasal symptoms such as runny nose, itchy nose, sneezing and nasal congestion after participants received the nasal spray.

This study is designed to look at the affect of SB-705498 on allergic rhinitis symptoms induced by an allergen chamber challenge.

This study seeks to prospectively demonstrate that Nasonex is better than placebo in relieving nasal congestion in patients with seasonal allergic rhinitis.

This was a one-day single dose trial conducted to compare patient's preference for Nasonex® (mometasone) versus Flonase® nasal spray. Each patient was randomized to take one dose (2 sprays in each nostril) of Nasonex or Flonase. Thirty minutes later, each patient was to take one dose of the opposite medication. Questionnaires were given to each patient after each drug dose to evaluate patient product preference.
