Mucus Viscosity in the Respiratory Tract

Mucus viscosity in the respiratory tract refers to the thickness and flow properties of mucus, a viscoelastic gel that lines and protects airway surfaces. It is determined primarily by water and mucin content. Optimal viscosity is essential for mucociliary clearance. Increased viscosity, often due to increased mucin concentration and decreased water content, is a key feature of several respiratory diseases, leading to airway obstruction and infection. Therapeutic strategies aim to reduce viscosity through hydration, mucolytics, or modulation of ion transport.

Varies depending on the drug; hydrating agents increase water content, mucolytics break down disulfide bonds in mucins, CFTR modulators correct defective chloride transport.
