What is the primary function of an antitussive medication?

The primary function of an antitussive medication is to suppress or relieve cough symptoms. Coughing is a reflex action that helps clear the airway of irritants, mucus, or foreign particles. However, in some scenarios, such as a dry, persistent cough that does not help clear mucus or when a cough disrupts sleep or daily activities, an antitussive is beneficial. These medications act on the cough center in the brain to decrease the urge to cough, providing relief from discomfort associated with coughing.

Understanding this function is essential in medication administration, as choosing the appropriate class of medication for a patient's specific symptoms can significantly affect their comfort and recovery.
