Function of Granisetron Hydrochloride

 

Granisetron hydrochloride is an antiemetic drug, mainly suitable for nausea and vomiting caused by radiotherapy, cytotoxic drug chemotherapy, and surgery. It has a better preventive and therapeutic effect. The mechanism of controlling nausea and vomiting is mainly through antagonism Central chemoreceptors and related receptors of neurotransmitters in the peripheral nervous system can inhibit the occurrence of nausea and vomiting. The selectivity of drug treatment is relatively high, and the adverse reactions to the central nervous system are relatively few. Less cause excessive sedation and other adverse reactions.

 

Granisetron hydrochloride is also used for surgical prevention. Generally, it only needs to be administered once. The preventive effect on nausea and vomiting can be more than 24 hours, so the effect time is relatively long. When using it, you need to pay attention to the gastrointestinal tract. Patients with obstruction are contraindicated.
