Used as a cough suppressant in various countries, particularly in Japan and some parts of Asia. It acts on the central nervous system to reduce the urge to cough, making it effective for treating non-productive coughs associated with common colds, bronchitis, and other respiratory conditions. Unlike opioid-based cough suppressants, tipepidine hydrochloride is non-narcotic and does not carry the same risk of dependence, making it a favorable alternative in certain patient populations. Some studies have also explored its potential as a neuropsychiatric agent due to its activity on monoamine transporters, suggesting possible applications in treating conditions like depression and ADHD, though such uses remain investigational.
