Tegaserod
Tegaserod is a serotonin type-4 (5HT4) receptor partial agonist. Tegaserod binds with high affinity at human 5HT4 receptors, present on caudate membranes, whereas it has no appreciable affinity for human recombinant 5HT3 receptors or human recombinant dopamine D2 receptors. In vitro and animal study has revealed that Tegaserod can trigger the peristaltic reflex via 5HT4 receptor activation and thereby enhance basal motor activity and normalize impaired GI motility.
Patient should be advised to take Tegaserod (6 mg twice daily) 30 minutes before meal.Patient should also be made aware of the possible occurrence of diarrhea during therapy. In most cases, the diarrhea occurred early, is transient, is most often observed as a single episode during the 12 week treatment period, and resolved with continued therapy.Patients should be instructed to consult their physician if they experience new or worsening abdominal pain not typical of their IBS symptoms.
No clinically relevant drug-drug interactions have been observed with dextromethorphan, theophylline, digoxin, oral contraceptives, and warfarin.
