Official title
A Randomized Placebo Control Trial to Evaluate the Efficacy of Chlorpheniramine Maleate Nasal Spray vs. Placebo for Acute or Chronic Rhinitis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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
