Therefore, its prevention can help avoid abdominal pain and discomfort in IBS. To find candidate drugs for visceral hypersensitivity, we screened existing medicines for their ability to prevent visceral sensitivity induced by colorectal distension (CRD) in rats and identified chlorpromazine, a typical antipsychotic drug, as a candidate compound. In this study, we investigated the effect of chlorpromazine on visceral hypersensitivity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Experimental Approach<\/jats:title>\n                    <jats:p>Visceral sensitivity (visceromotor response) was monitored by measuring the electrical activity of the abdominal external oblique muscle contraction in response to CRD using a barostat apparatus.

Interestingly, atypical antipsychotic drugs, quetiapine and risperidone, ameliorated butyrate\u2010induced visceral hypersensitivity, whereas the typical antipsychotic drugs, haloperidol and sulpiride, did not. Pharmacological analysis using specific inhibitors showed that a selective 5\u2010HT\n                      <jats:sub>2A<\/jats:sub>\n                      receptor antagonist, ketanserin, suppressed butyrate\u2010induced visceral hypersensitivity, whereas a selective dopamine D\n                      <jats:sub>2<\/jats:sub>\n                      receptor antagonist, L\u2010741626, did not.
