Mucolytics

Mucolytics Mucolytics

Mucolytics are prescribed to facilitate expectoration by reducing sputum viscosity. In some patients with chronic obstructive pulmonary disease and a chronic productive cough, mucolytics can reduce exacerbations; mucolytic therapy should be stopped if there is no benefit after a 4-week trial. Steam inhalation with postural drainage is effective in bronchiectasis and in some cases of chronic bronchitis.

Mucolytics should be used with caution in those with a history of peptic ulceration because they may disrupt the gastric mucosal barrier.

Reduces the viscosity of mucus in the tracheobronchial tree; this is expected to make carriage of mucus up the tracheobronchial tree by the mucociliary clearance mechanism easier, and also to increase ease of expectoration of mucus during coughing.

To assist in control of respiratory disease involving production of excessive tenacious mucus.
