    Excessive respiratory mucus, rich in glycoproteins, causes airway diseases like asthma. Current treatments focus on underlying conditions, secretion clearance, or reducing mucus production.

    Area of Science:

    • Pulmonary Medicine
    • Respiratory Physiology

    Background:

    • Respiratory mucous glycoproteins are crucial for airway protection.
    • However, excessive secretions contribute to significant morbidity in diseases such as asthma, chronic bronchitis, and cystic fibrosis.
    • These secretions are complex mixtures influencing viscosity and elasticity.

    Purpose of the Study:

    • To review the physiological control of mucous glycoprotein secretion.
    • To explore the mechanisms of respiratory mucus hypersecretion.
    • To outline current therapeutic strategies for managing excessive respiratory mucus.

    Main Methods:

    • Literature review of physiological mechanisms.
    • Analysis of inflammatory mediators and cellular involvement.
    • Summary of existing treatment modalities.

    Main Results:

    • Mucous glycoproteins determine respiratory secretion viscosity and elasticity.
    • Cholinergic, alpha-adrenergic, and beta-adrenergic stimuli influence secretion.
    • Mediators from hypersensitivity/inflammatory states and phagocytic cells contribute to hypersecretion.

    Conclusions:

    • Effective management of respiratory mucus hypersecretion requires addressing underlying diseases.
    • Improving secretion clearance is a key therapeutic goal.
    • Reducing mucus secretion via glucocorticosteroids or anticholinergic drugs offers treatment options.
