Filter by:The purpose of this replicate study to FFU105924 is to provide data on subject preference of FFNS as compared with FPNS.
The purpose of this study is to establish whether MRI scanning is a sensitive measure of the effects of existing drug treatments on nasal dimensions following challenge with intranasal allergen in subjects with hayfever. If successful this technique could be applied to increase confidence for internal decision making and ultimately may be used to assess how effective a new drug treatment is.
This study will evaluate whether multiple nasal antigen challenges with dust mite allergen produces increases in nasal symptoms and local allergic inflammatory cells in the nose and the blood.
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 primary objective of the study is to compare nighttime symptom relief of fluticasone furoate nasal spray versus oral fexofenadine
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.
This study will hope to show that the treatment of the patient's perennial allergic rhinitis (PAR) using Nasonex® (mometasone furoate nasal spray) will result in improvement of the nasal symptoms of PAR and of nighttime sleep-disordered breathing, thereby resulting in improved sleep quality, less daytime sleepiness, improved daytime functioning, and improved quality of life.
Study objective is to verify the superiority of CTZ DS to the placebo groups in the change of total nasal symptom score (TNSS) over the total treatment period from the score of the baseline assessment period.
The aim of this study is to compare the effect of montelukast and cetirizine on allergic inflammation measured by exhaled nitric oxide concentration in children with seasonal allergic rhinitis.
The investigators wish to evaluate the onset of tolerance to nasal decongestants like oxymetazoline (available over the counter) and the mechanism of tolerance particularly with differential effects on alpha 1 and alpha 2 adrenoreceptors on the nose. The investigators will 'tease' out by using an alpha 1 blocker called Prazosin. The investigators hypothesize that alpha 1 receptors mediate arterial constriction and this will be captured by measuring nasal blood flow. The investigators also hypothesize that alpha 2 receptors mediate venous sinusoid constriction and this the investigators will capture by airflow parameters like Peak Nasal Inspiratory Flow, Rhinomanometry, Oscillometric indices etc.
