Tegaserod Maleate 5-HT Receptor agonist

Name: Tegaserod Maleate
Brand: Selleck Chemicals
SKU: S5401
Rating: 5 (2 reviews)

Cat.No.S5401

Tegaserod Maleate(HTF-919) is a hydrogen maleate salt form of tegaserod, which is a 5-HT4 receptor partial agonist and binds with high affinity to 5-HT4 receptors. It has limited affinity for 5-HT1 receptors and no appreciable affinity for other 5-HT receptors, muscarinic, adrenergic, dopaminergic or opiate receptors.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	5-HT4 receptor
In vitro	In guinea-pig and rat colon, luminal application of tegaserod activates 5-HT4 receptors on intrinsic primary sensory neurons that release calcitonin gene-related peptide which in turn activates cholinergic interneurons stimulating the peristaltic reflex. In isolated segments of guinea-pig colon, intraluminal tegaserod increased the velocity of propulsion of artificial faecal pellets through the stimulation of the same receptor. In rat distal colon, intraluminal tegaserod stimulated 5-HT4 4 receptors on colonocytes to secrete chloride and water through an adenylyl cyclase-dependent pathway.
In vivo	In a study in dogs tegaserod 0.1 or 0.3 mg/kg i.v. increased the motility of the antrum, duodenum and jejunum in both fasting and fed conditions. In a model of delayed gastric emptying, the same doses of tegaserod restored normal gastric transit time. Tegaserod 0.3 mg/kg in rats was able to increase gastric and small bowel motility while in a model of postoperative ileus it was able to restore gastric motility. In humans, pharmacokinetic analysis reveals that tegaserod is rapidly absorbed following oral administration. Absolute bioavailability is 11 ± 3% and is decreased by 50% under fed conditions. The time to reach peak plasma concentration ranges from 1-1.3 h. In the bloodstream, tegaserod is predominantly bound by α1-glycoprotein and does not cross the blood-brain barrier to any significant extent. The terminal elimination half time is 11 ± 5 h. Age and gender do not influence the pharmacokinetics of tegaserod and tegaserod has the potential for good tolerability.
