Noscapine Hydrochloride Hydrate is primarily used in medical research and treatment due to its antitussive (cough-suppressing) properties. It is often employed as a non-opioid cough suppressant, making it a safer alternative for managing coughs without the risk of addiction associated with opioid-based medications. Additionally, it has been investigated for its potential anticancer properties, particularly in inhibiting the growth of certain cancer cells by interfering with microtubule dynamics. This makes it a subject of interest in oncology research, where it is studied for its ability to induce apoptosis (programmed cell death) in cancer cells while sparing normal cells. Its low toxicity profile further enhances its appeal for therapeutic applications.
