Filter by:This was a study to measure the ability of desloratadine and levocetirizine to decrease nasal obstruction in subjects who had study-induced allergic rhinitis. Study participants had allergic rhinitis symptoms induced in a Vienna Challenge Chamber and then received desloratadine or levocetirizine for 8 days. After at least a 10 to 35-day washout period (time when no drug is given), subjects received the opposite treatment for 8 days. Subjects had their total nasal symptom measured.on the 8th day of each treatment period.
This study will compare the effectiveness of QAV680 against placebo in treating the symptoms of seasonal allergic rhinitis in an Environmental Exposure Chamber.
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.
This was a single-dose study to determine the time it takes for mometasone furoate nasal spray to go in effect, after a single dose of 2 sprays per nostril. Patients who are eligible were exposed to ragweed pollen for 3 hours on one or two occasions. Patients who experienced adequate symptoms during the pollen exposure phase came back for a Treatment Phase visit. During the Treatment Phase visit, patients were exposed to ragweed pollen for 2 hours and then received either mometasone or placebo nasal spray. Symptom evaluations began on the patients every hour for the next 11 hours.
This study was conducted to see if mometasone nasal spray is efficaceous for the treatment of perennial allergic rhinitis. Patients will be randomized to active mometasone, placebo mometasone, active fluticasone, or placebo fluticasone.
This was a randomized, double-blind, parallel-group, multicenter study that used both an active control (fexofenadine) and a placebo control to evaluate desloratadine 5 mg once daily during a 15-day treatment period. The active treatments and placebo were allocated in a 2:2:1 ratio.
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 was a randomized, double-blind, parallel-group, multicenter study that used both an active control (fexofenadine) and a placebo control to evaluate desloratadine 5 mg once daily during a 15-day treatment period. The active treatments and placebo were allocated in a 2:2:1 ratio.
This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.
This is a multicenter, open-label, randomized, parallel group comparison study to verify the clinical equivalency of the old formulation (50 mcg as mometasone furoate [MF] in 50 μL of solution per spray) to the new formulation (50 mcg as MF in 100 μL of solution per spray) in patients with perennial allergic rhinitis.
