Dextromethorphan is classified as which of the following?

Dextromethorphan is classified as an antitussive, which means it is used to suppress coughing. This classification is essential when considering its intended use for managing symptoms of coughs, particularly those associated with colds or other respiratory conditions. Dextromethorphan works by acting on the cough center in the brain, helping to alleviate the cough reflex, which can be particularly useful in providing relief for patients who have a persistent cough that disrupts their daily activities or sleep.

Understanding the specific classifications of medications like dextromethorphan is crucial for pharmacy technicians, as this knowledge helps in properly advising patients, filling prescriptions accurately, and recognizing potential contraindications or interactions with other medications. While other categories such as antidepressants, analgesics, and antihistamines address different medical concerns—like mood disorders, pain relief, or allergy symptoms—dextromethorphan's primary and most relevant function is its role as an antitussive.
