Filter by:In a previous study the investigators found that many bakery workers were sensitized to storage mites, and many had rhinitis symptoms. The role of storage mites as an occupational allergen with clinical relevance has been questioned, and the investigators wanted to investigate whether a nasal provocation with a storage mite extract would trigger symptoms and objective signs of rhinitis in bakery workers and a control group.
This study is designed to look at the affect of SB-705498 on allergic rhinitis symptoms induced by an allergen chamber challenge.
Allergic rhinitis is an under diagnosed global health problem which affects up to 25% of the population worldwide. It has been reported as being one of the 10 most common causes for attendance to primary care clinics. It is clinically defined as a symptomatic disorder of the nose induced by an IgE mediated inflammation following allergen exposure of the membranes lining the nose and is characterized by varying combinations of nasal symptoms including sneezing, nasal blockage, rhinorrhoea and itching. Intra nasal corticosteroids form the cornerstone of anti-inflammatory therapy in allergic rhinitis and there is increasing interest in the role of intranasal beta 2 agonists in the management of allergic rhinitis. The question therefore arises as to whether salmeterol exhibits such synergistic activity in the nose in terms of potentiating the steroid response of fluticasone.
This is a study to evaluate the efficacy and safety of grass sublingual tablet (SCH 697243) versus placebo in the treatment of grass pollen-induced allergic hayfever symptoms. Participants will receive either the sublingual grass tablet or a placebo tablet during the study. It is expected that those participants receiving the active sublingual grass tablet will have less hayfever symptoms and need less medications to treat hayfever symptoms during the grass pollen season.
The primary objective will be to compare the impact of the study formulations on alergic rhinitis carriers.
This was an open label, three way study in participants with symptomatic allergic rhinitis. The following 3 treatments were administered to each subject during dosing periods 1, 2 and 3, respectively: - Treatment A: Single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 1. - Treatment B: Single intranasal dose of oxymetazoline hydrochloride followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) 30 minutes later on Day 1 of Period 2. - Treatment C: Seven days of treatment with intranasal fluticasone propionate (between Periods 2 and 3) followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 3. Subjects remained resident in the Clinical Unit from Day 1 until the morning of Day 2 in each period and there was a washout period of 2 to 7 days between periods. A post study medical was performed within 7 days of Period 3. The objectives of this study were: - To assess the pharmacokinetics (PK) of intranasal ketorolac in participants with symptomatic allergic rhinitis. - To assess the effects of a single dose of intranasal oxymetazoline hydrochloride on the pharmacokinetics and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis. - To assess the effects of chronic administration of fluticasone propionate on the bioavailability and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis.
The purpose of this research study is to investigate whether sublingual immunotherapy (SLIT, grass pollen tablets under the tongue) has long term effects in severe hay fever.
The overall development plan is to show that the combination of tried-and-proven decongestant/antihistamine ingredients (pseudoephedrine hydrochloride and chlorpheniramine maleate), plus a very small amount of belladonna alkaloids (.24 mg atropine sulfate) is a comprehensive, safe and effective B.I.D. drug treatment regimen, indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and children 12 years of age and older. Treated symptoms include nasal congestion, sneezing, rhinorrhea, itchy nose, itchy/watery eyes, and post nasal drip syndrome [reduction in tickly cough (acute or chronic), mucus in the back of the throat, sore throat, and hoarseness]. Considering the favorable safety and efficacy results of Phase 1 and Phase 2, the purpose of Phase 3 is to assess and compare the safety and efficacy of the study drug in a larger group comparatively with a placebo control group. Objectives: A) To report and compare total symptom scores (TSS) by SAR subjects rating the efficacy of STAHIST vs. placebo in relieving nasal congestion, rhinorrhea, nasal itching, sneezing, and post-nasal drip over the two-week study period. B) Report any side effects or adverse drug reactions and rate the severity of any incident. C) Compare and report each symptom score, total nasal symptom scores (TNSS), and post-nasal drip symptom scores (PND-S) between the two study arms.
Background: Nasal allergen challenge (NAC) is useful to study the pathophysiology of rhinitis, and multiple challenges may more adequately approximate natural exposure. Objective: To determine the effect of 4 consecutive daily NAC, on clinical and inflammatory parameters in rhinitics with or without asthma.
The purpose of this study is to determine whether a neuropeptide, substance P, when injected along with an allergen, such as ragweed, can reduce allergic reactivity.
