Mechanism of action

Libexin (prenoxdiazine) works through a combination of local anesthetic effects on the airways and central cough suppression without opioid activity. It reduces the sensitivity of cough receptors in the respiratory tract, thereby decreasing the cough reflex while maintaining normal airway clearance and respiratory function.
