Active clinical trials for "Rhinitis, Allergic"

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.

The primary objective will be to compare the impact of the study formulations on alergic rhinitis carriers.

The purpose of this study is to see if a nasal steroid drug delivered to the nose with the NasoNeb™ inhaler improves the symptoms of people with perennial allergic rhinitis (year round allergy symptoms).

The purpose of this study is to determine the onset of action of two commercially available over-the-counter antihistamines (Loratadine and Fexofenadine) in a model of seasonal allergic rhinitis (SAR). Participants undergo sensitization exposures to Mountain Cedar (juniperus ashei) pollen in a Biogenics Research Chamber; those who demonstrate an adequate allergic response determined by the Major Symptom Complex (MSC) score will then receive drug.

This study is to assess the onset of action of fixed drug combination of azelastine hydrochloride and fluticasone propionate nasal spray (MP-AzeFlu) in treating the nasal symptoms of seasonal allergic rhinitis (SAR) induced by an allergen challenge in an Environmental Exposure Chamber (EEC).

This study aimed to assess the impact of air cleanser on allergic rhinitis patients and indoor air quality. Air cleaners will be installed in the bedrooms and living rooms of the mite allergic rhinitis patients who aged 18-60 years. Main parameters: - Symptom medication score of allergic rhinitis Supportive parameters: Visual analog scale of allergic rhinitis Quality of life score of allergic rhinitis Indoor air quality measurement Indoor allergen level measurement

To compare patient perceptions of the sensory attributes, including taste and aftertaste, of Olopatadine relative to azelastine when administered as a single dose in patients with allergic rhinitis.

After a nasal allergen challenge it should be possible to measure markers of inflammation that may be useful to assess the properties of future drugs. If these markers are reproducible and impacted by the study drugs they could be useful for future drug development.

The purpose of the study is to find out if montelukast can be used to treat the various symptoms of allergic syndrome.

The objectives of this study are to evaluate and compare patient preference for FF (Fluticasone Furoate) and FP (Fluticasone Propionate Aqueous)nasal sprays in the treatment of allergic rhinitis following single-dose administration.
