Alosetron Hydrochloride
Based on 1 publication(s) in Google Scholar
Alosetron Hydrochloride (GR 68755C) is a potent and highly selective serotonin 5-HT3 receptor antagonist. Alosetron Hydrochloride is used for the research of irritable bowel syndrome (IBS). Alosetron blocks the fast 5HT3-mediated depolarisation of guinea-pig myenteric and submucosal neurons, with IC50 at ~55 nM. Alosetron Hydrochloride attenuates the visceral nociceptive effect of rectal distension in conscious or anaesthetised dogs. Anti-inflammatory effects.
