Sympathomimetics in nasal allergy.

    Summary

    Topical alpha-adrenoceptor agonists like phenylpropanolamine significantly reduce nasal congestion and airway resistance in allergic rhinitis patients. This offers a potential symptomatic treatment for mucosal congestion associated with the condition.

    Area of Science:

    • Allergy and Immunology
    • Pharmacology
    • Otorhinolaryngology

    Background:

    • Allergic rhinitis frequently causes significant nasal congestion and airway obstruction.
    • Current treatments may not fully address mucosal congestion symptoms.

    Purpose of the Study:

    • To evaluate the efficacy of a topical alpha-adrenoceptor agonist, phenylpropanolamine, in managing allergic rhinitis symptoms.
    • To assess the impact on nasal airway resistance and congestion.

    Main Methods:

    • A placebo-controlled, double-blind, crossover study was conducted.
    • 10 subjects with allergic rhinitis underwent nasal allergen challenge.
    • Nasal airway resistance was measured using anterior rhinomanometry; symptoms (blockage, secretion, sneezes) were scored.

    Main Results:

    • Topical phenylpropanolamine significantly reduced nasal airway resistance.
    • The degree of nasal blockage was also significantly decreased.
    • Symptom scores indicated a reduction in congestion.

    Conclusions:

    • Topical alpha-adrenoceptor agonists demonstrate potential for symptomatic relief in allergic rhinitis.
    • Phenylpropanolamine may be an effective treatment for mucosal congestion in allergic rhinitis.
