Which agent is a nonsedating antihistamine

Investigators conducted a multicenter, double-blind, placebo-controlled, parallel-group trial13 in 204 children (six to 12 years of age) and adolescents (13 to 18 years of age) with allergic or nonallergic perennial rhinitis.Patients with nonallergic perennial rhinitis who used ipratropium had a 41 percent mean decrease in severity and a 37 percent decrease in duration of rhinitis with excellent tolerability, compared with decreases of 15 and 17 percent in severity and duration, respectively, in the placebo group.13Certain nasal corticosteroids, such as mometasone furoate (Nasonex), are approved by the U. Food and Drug Administration (FDA) for children older than two years and improve the symptoms of congestion and nasal obstruction.A stepwise pharmacologic approach may then be employed, choosing the initial intervention based on the patient’s predominant symptoms.If the presenting symptom is solely rhinorrhea, a topical anticholinergic is the logical first step.614 With nasal congestion and obstruction only, topical corticosteroids would be a wise starting point for therapy.6 If the patient presents with the full range of symptoms including rhinorrhea with sneezing, postnasal drip, and congestion, a topical antihistamine may be initiated.6 describes a possible approach.

The minimum level of diagnostic testing needed to differentiate between the two types of rhinitis also has not been established. Specific approaches to the management of rhinitis in children, athletes, pregnant women, and older adults are discussed.

An algorithm is presented that is based on a targeted history and physical examination and a stepwise approach to management that reflects the AHRQ evidence report and U. A = consistent, good-quality, patient-oriented evidence; B = inconsistent or limited-quality, patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, expert opinion, or case series.

In studies and in practice, allergic rhinitis is excluded or implicated as the cause of symptoms by using conventional skin testing or by evaluation for specific Ig E antibodies to known allergens.7 According to the AHRQ,6 the results of “only one small recent study suggest that total serum Ig E may be as useful as specific allergy skin prick tests, which, in turn, are more useful than radioallergosorbent testing in confirming a diagnosis of allergic rhinitis.”8 The lack of sensitivity and specificity of nasal cytology, total serum Ig E, and peripheral blood eosinophil counts, which have been favored in the past for differentiating among rhinitis syndromes, makes their clinical use problematic.1 The minimum level of testing needed to confirm or exclude a diagnosis of vasomotor rhinitis has not been established in the literature.6Once a working diagnosis of vasomotor rhinitis has been made, the patient can be empowered to avoid known environmental triggers as much as possible.

These may include odors (e.g., cigarette smoke, perfumes, bleach, formaldehyde, newspaper or other inks); auto emission fumes; light stimuli; temperature changes; and hot or spicy foods.

A topical antihistamine (e.g., azelastine [Astelin]), topical corticosteroids (e.g., budesonide), and topical anti-cholinergics (e.g., ipratropium) may be tried.
