Alizapride Hydrochloride is primarily used as an antiemetic agent to prevent and treat nausea and vomiting. It is particularly effective in managing symptoms associated with chemotherapy, radiotherapy, and postoperative recovery. The compound works by blocking dopamine receptors in the brain, which helps to reduce the sensation of nausea and the urge to vomit.

In clinical settings, it is often administered to patients undergoing cancer treatment, as these therapies frequently induce severe nausea and vomiting. Additionally, it is used in surgical patients to prevent postoperative nausea, enhancing recovery comfort.

Alizapride Hydrochloride is also beneficial in treating nausea and vomiting caused by gastrointestinal disorders or other medical conditions. Its relatively low sedative effect makes it a preferred choice in situations where maintaining patient alertness is important.

Overall, it plays a crucial role in improving the quality of life for patients experiencing nausea and vomiting due to various medical treatments or conditions.
