Tegaserod: a serotonin 5-HT4 receptor agonist for treatment of constipation-predominant irritable bowel syndrome.

Activation of serotonin 5-HT(4) receptors has been proposed as treatment for irritable bowel syndrome, a common, complex and distressing gastrointestinal disorder. Abnormal intestinal motility and sensitivity in irritable bowel syndrome patients can result in diarrhea, constipation, abdominal pain, bloating, headache and fatigue; these and other symptoms can lead to exacerbation ...
of psychological stress, which may in turn induce further physiological abnormalities and patient discomfort. The serotonin agonist tegaserod binds with high affinity to 5-HT(4) receptors and has demonstrated potent pharmacological effects on the mid- and distal gut. Tegaserod has been safely employed in clinical trials where it has demonstrated efficacy in normalizing intestinal function, thereby improving irritable bowel syndrome symptoms.
