    Abstract:
    Noninfectious rhinitis and the clinical pharmacology of drugs used in its treatment, including specific treatment recommendations, are reviewed. Characterized by hyperreactivity of the nasal mucosa to a variety of stimuli, noninfectious rhinitis can be classified either as seasonal or perennial allergic rhinitis (when antigens can be identified) or as vasomotor or nonallergic rhinitis (when antigens are not identifiable). However, noninfectious rhinitis is probably better viewed as a continuum between these extremes rather than as definitive categories. Treatment measures include removal of offending agents when possible, and injection of allergenic extracts to decrease sensitivity to inhalant allergens. Among the pharmacologic alternatives, the classical H1 antihistamines competitively inhibit the action of mast-cell histamine at its receptor sites and thus decrease sneezing, nasal pruritus, rhinorrhea, and conjunctivitis. Orally bioavailable alpha-adrenergic agents such as pseudoephedrine and phenylpropanolamine decrease nasal congestion that responds poorly to antihistamines. Topical vasoconstrictors are contraindicated in chronic rhinitis because of the complications of rebound congestion. Systemic corticosteroids are effective but rarely appropriate for chronic rhinitis. Potent topical corticosteroids such as intranasal beclomethasone dipropionate are useful for severe nasal congestion. Cromolyn sodium, an inhibitor of histamine release from mast cells, appears to have some efficacy in suppressing symptoms of allergic rhinitis and conjunctivitis when used topically. Anticholinergics have occasionally been recommended to reduce rhinorrhea, but little data on their efficacy are available.
