9 Clinical Trials for Various Conditions
The purpose of this study is to determine if Astepro Nasal Spray (0.1% azelastine hydrochloride) is as safe as Astelin Nasal Spray (0.1% azelastine hydrochloride)
The purpose of this study is to examine safety and efficacy of Patanase and Astelin in treating the symptoms of non-allergic vasomotor rhinitis (VMR).
The purpose of this study is to determine the safety of the oral formulation of levocetirizine in children ages 1 to less than 6 years old who suffer from allergic rhinitis or chronic urticaria of unknown origin.
Post-market study to continue to evaluate the effectiveness of the RhinAer Stylus for chronic rhinitis and the effect of treatment on inflammatory biomarkers.
Allergic rhinitis is defined as the symptoms of sneezing, nasal itching, airflow obstruction, and, mostly, clear nasal discharge caused by IgE-mediated reactions against inhaled allergens and involving mucosal inflammation driven by T cells (Th2) auxiliary type 2. pollens and molds, as well as allergens from perennial interiors, such as dust mites, pets, pests, and some molds. The pattern of dominant allergens depends on the geographic region and degree of urbanization, but the general prevalence of sensitization to allergens does not vary among census districts in the United States. This research proposes to study a separate antihistamine in a nasal spray. It is important to note that this antihistamine is available without prescription (OTC) and has been studied intranasal since the 1950s1
Nasal glucocorticosteroids (GCS) are considered first-line therapy for both allergic and non-allergic rhinitis.1-3 Nasal congestion can persist despite maximum treatment with intranasal GCS. No other drugs are superior to intranasal GCS in relieving nasal congestion. For example, antihistamines are not effective in relieving congestion.1 Oral decongestants are somewhat beneficial in relieving nasal congestion but can elevate blood pressure, cause restlessness, and cause urinary retention. Oxymetazoline, however, is a potent decongestant and the addition of it to a nasal GCS should add a considerable decongestant benefit. It may also be beneficial in patients with persistent nighttime congestion despite maximum dosages of nasal GCS. Oxymetazoline is currently recommended for three days use because of the proposed risk of rhinitis medicamentosa,4 which is increased nasal congestion caused by prolonged use of nasal decongestant sprays.5-8 The term RM was coined early in the twentieth century after several case reports described patients developing rebound congestion after using first generation intranasal decongestants such as privine hydrochloride and ephedrine for prolonged periods6,7. The histopathology and mechanism of RM has been based on animal models which may not be pertinent to humans.9-13 Studies using oxymetazoline, a newer intranasal decongestant, in individuals without rhinitis have shown conflicting evidence for the development of RM.14-16 For example, normal individuals without rhinitis using oxymetazoline three times daily for four weeks did not develop RM.17 Also, it is unknown the frequency of administration and dosage of oxymetazoline it takes to induce RM or whether RM is just a return to a patient's baseline nasal congestion as present before beginning oxymetazoline. It is also unknown whether RM is more likely or only occurs with older vasoconstrictors such as privine hydrochloride and ephedrine rather than oxymetazoline. Nasal GCS reduce the amount of rebound congestion in patients with perennial allergic rhinitis who have reportedly developed RM.18 Nasal GCS decrease nasal mucosa edema, recruitment of neutrophils and mononuclear cells, cytokine production, and late-phase nasal mediators.19-21 They may offer a protective benefit from the risk of developing RM. Oxymetazoline may also decrease inferior turbinate hypertrophy thereby permitting better adsorption of the nasal GCS. Hypothesis The addition of oxymetazoline to a nasal GCS for fourteen days will decrease the amount of congestion in subjects with allergic or non-allergic rhinitis with persistent congestion despite maximum recommended dosages of a nasal GCS. It is also hypothesized that nasal GCS protect against the development of RM secondary to oxymetazoline.
To determine the safety of levocetirizine in children ages 6-11 months with symptoms of allergic rhinitis or chronic idiopathic urticaria.
Safety and effectiveness of sinus balloon dilation in patients 2-21 years old.
The goal of this research project is to explore the impact of the addition of budesonide to high-volume, low-pressure nasal sinus saline irrigation (aka "Neti-Pot"-type systems) for patients with chronic rhinosinusitis with or without nasal polyps.
