Evidence reviews

Drug Class Review: Newer Antihistamines: Final Report Update 2 [Internet]

Antihistamines inhibit the effects of histamine at H1 receptors. They have a number of clinical indications including allergic conditions (e.g., rhinitis, dermatoses, atopic dermatitis, contact dermatitis, allergic conjunctivitis, hypersensitivity reactions to drugs, mild transfusion reactions, and urticaria), chronic idiopathic urticaria (CIU), motion sickness, vertigo, and insomnia.

Drug Class Review: Nasal Corticosteroids: Final Report Update 1 [Internet]

Nasal corticosteroids are a safe and effective treatment option for both allergic and non-allergic rhinitis. There are currently 8 different nasal corticosteroid preparations on the U.S. market. The nasal sprays differ with respect to delivery device and propellant, as well as potency and dosing frequency. The purpose of this review is evaluating the comparative evidence on the benefits and harms of the nasal corticosteroids to help policy makers and clinicians make informed choices.

The quality of the evidence was generally poor. Evidence was insufficient to allow recommendation of a trial of any particular intervention. Further research is needed to establish a definition of ETD, its relation to broader middle ear ventilation problems and clear diagnostic criteria.
