Calmactin Uses, Dosage, Side Effects, Food Interaction and all others data.

Calmactin is a 5HT-3 antagonist made by Solvay Pharmaceuticals that is currently under trial phase in the EU and US.

Calmactin is an orally formulated medication that blocks the action of 5-hydroxy-tryptamine 3 (5-HT3) receptors. Phase III studies of cilansetron had been suspended by Solvay in order to assess whether the drug possesses safety concerns similar to alosetron. Alosetron, also a 5-HT3 antagonist, was withdrawn from the market due to questions regarding its safety. Phase III testing with cilansetron has since resumed. In June 2005 the company announced that they were reviewing the priority of the cilansetron program.

How Calmactin works

Calmactin is a potent and selective 5-HT₃ receptor antagonist. 5-HT₃ receptors are nonselective cation channels that are extensively distributed on enteric neurons in the human gastrointestinal tract, as well as other peripheral and central locations. Activation of these channels and the resulting neuronal depolarization affect the regulation of visceral pain, colonic transit and gastrointestinal secretions, processes that relate to the pathophysiology of irritable bowel syndrome (IBS). 5-HT₃ receptor antagonists such as cilansetron inhibit activation of non-selective cation channels which results in the modulation of the enteric nervous system.
