    Summary
    This summary is machine-generated.

    Cromolyn sodium helps prevent allergic asthma attacks by stopping chemical mediators from being released. It is not effective for acute attacks but reduces overall symptoms and medication needs in severe cases.

    Area of Science:

    • Immunology
    • Pulmonology
    • Pharmacology

    Background:

    • Allergic asthma involves antigen-IgE interaction on mast cells, releasing mediators that cause bronchoconstriction.
    • Key mediators include histamine and slow-reacting substance of anaphylaxis.
    • Current prophylactic treatments include antigen avoidance and desensitization.

    Purpose of the Study:

    • To evaluate the prophylactic efficacy of cromolyn sodium in managing allergic asthma.
    • To understand the mechanism of action of cromolyn sodium in preventing mast cell mediator release.

    Main Methods:

    • The study focuses on the mechanism of mast cell mediator release in allergic asthma.
    • It examines the effect of cromolyn sodium on this release process.

    Main Results:

    • Cromolyn sodium appears to inhibit the release of chemical mediators from mast cells.
    • This agent is ineffective during acute asthma attacks.
    • It significantly reduces the frequency of asthma attacks and the requirement for other medications in severe perennial asthma patients.

    Conclusions:

    • Cromolyn sodium is a valuable prophylactic treatment for severe perennial allergic asthma.
    • Its mechanism involves impeding mast cell mediator release, not treating acute symptoms.
