Tegaserod (3‐(5‐methoxy‐1H‐indol‐3ylmethylene)‐N‐pentyl‐carbazimidamide), an aminoguanidine indole derivative of serotonin, is a selective partial agonist highly selective for 5‐HT4 receptor with an affinity constant in the nanomolar range. Tegaserod, by acting as an agonist at neuronal 5-HT4 receptors, triggers the release of further neurotransmitters such as calcitonin gene-related peptide from sensory neurons. The activation of 5-HT4 receptors in the gastrointestinal tract stimulates the peristaltic reflex and intestinal secretion, as well as inhibits visceral sensitivity. In vivo studies showed that tegaserod enhanced basal motor activity and normalized impaired motility throughout the gastrointestinal tract. Zelnorm® (tegaserod maleate) is indicated for the short-term treatment of women with irritable bowel
syndrome (IBS) whose primary bowel symptom is constipation. In addition Zelnorm® is indicated for the treatment of patients less than 65 years of age with
chronic idiopathic constipation.

Sample Use Guides
IBS with Constipation: The recommended dosage of Zelnorm® (tegaserod maleate) is 6 mg taken
twice daily orally before meals for 4 to 6 weeks. For those women who respond to therapy at 4-6
weeks, an additional 4-6 week course can be considered.
Chronic Idiopathic Constipation: The recommended dosage of Zelnorm is 6 mg taken twice daily
orally before meals. Physicians and patients should periodically assess the need for continued therapy.
Route of Administration:
Oral
Exposure of rat colonic mucosa to tegaserod in the range of 5 nM to 5 muM for 5 or 10 min caused rapid time- and concentration-dependent desensitization of the peristaltic reflex induced by mucosal stroking.
Samples of whole blood-citrate mixtures were incubated with different tegaserod concentrations mimicking human Cmax values (10 nM), 3.3 times, and 10 times Cmax for at least 1 hour.
