Active clinical trials for "Rhinitis, Allergic"

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.

The purpose of this study is to evaluate how well mometasone furoate nasal spray (MFNS) works to relieve SAR symptoms compared to Placebo when symptoms are induced in a chamber setting. Evaluation will be based on subjects self-assessed nose symptoms. Other areas the study will evaluate are: 1) changes in eye symptoms (ocular symptom severity score) after dosing 2) how long MFNS works in relieving the nose (nasal) and eye (ocular) symptoms after 7 daily doses, 3) measurements of nose (nasal) blockage (obstruction), and 4) measurements of the subject's opinion of the study drugs by asking different questions. This study is could last up to 53 days for some subjects.

Allow physicians not familiar with anti-leukotriene based therapy to test it

The primary objective of this study was to compare Placebo to Captisol-Enabled Budesonide + Azelastine in a single spray and two separate sprays (Budesonide + Azelastine) in patients with Seasonal Allergic Rhinitis exposed to controlled ragweed pollen.

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 is a post marketing study to confirm the appropriate dose of loratadine in children by obtaining drug concentration data at multiple time points per child and adult patient, after the patient receives repeated administrations of the approved dose of loratadine.

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.
