Narcotine is primarily used in the pharmaceutical industry for its antitussive properties, effectively reducing coughing by acting on the central nervous system. It is often incorporated into cough syrups and other respiratory medications to provide relief from persistent or severe coughs. Additionally, narcotine has been studied for its potential role in reducing inflammation and its mild analgesic effects, making it a component in some pain-relief formulations. Research is ongoing to explore its broader therapeutic applications, including its effects on certain neurological conditions.
