Ondansetron Hydrochloride Dihydrate

**Ondansetronum hydrochloricum and d dicharlate** Ondansetronum hydrochloricum is an antiemetic with central action. It selectively blocks serotonin receptors in the brain, apparently at the level of neurons in the vomiting center. Reduces the stimulating effect of enkephalins, hyperpolarizes and inhibits the transmission of excitation in chemoreceptors. Withdrawal therapy with the drug prevents the development of vomiting (after cerulosis vomiting, after taking aminazine), reduces the duration and severity of the emetic effects of ethyl borates and alcohol. Effective in cases of vomiting due to cytostatics, radiation sickness, and early postoperative conditions.
