Used as a non-opioid antitussive agent to suppress dry, non-productive coughs. It acts centrally on the cough reflex in the medulla oblongata, reducing the urge to cough without significant respiratory depression. Commonly found in over-the-counter cough syrups and tablets. Also exhibits mild bronchodilatory and anti-inflammatory effects, making it suitable for use in respiratory conditions like acute bronchitis, pharyngitis, and asthma-related cough. Not associated with sedation or addiction, offering a favorable safety profile compared to codeine-based cough suppressants.
