About Antitussives (Opioid Antitussives and DM).

The phrase "Antitussives (Opioid Antitussives and DM)" represents a combined functional category rather than a single standardized pharmacological class, grouping centrally acting opioid suppressants—principally codeine and hydrocodone—with dextromethorphan (DM), a synthetic morphinan derivative.

These agents act primarily within the central nervous system to elevate the cough reflex threshold in the brainstem, with opioids stimulating central mu-opioid receptors and dextromethorphan exerting non-opioid antitussive effects largely via sigma-1 receptor agonism and NMDA receptor antagonism.

Clinically, medications in this grouping are indicated for the short-term, symptomatic suppression of nonproductive cough associated with acute upper respiratory tract infections, allergies, and bronchitis.
