antitussive
antitussive
An agent that suppresses cough. Antitussives have a central or a peripheral action on the cough reflex, or a combination of both. Compare with  <em>expectorants</em>, which are considered to increase the volume of secretions in the respiratory tract, so facilitating their removal by ciliary action and coughing, and <em>mucolytics</em>, which decrease the viscosity of mucus, facilitating its removal by ciliary action and expectoration.
