Dược Lực Học :
Cilansetron 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 Alosetron, also a 5-HT3 antagonist, was withdrawn from the market due to questions regarding its safety.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.
Cơ Chế Tác Dụng :
Cilansetron is a drug that is a 5HT-3 antagonist currently under trial phase in the EU and US. It is manufactured by Solvay Pharmaceuticals INC. [Wikipedia]
Cilansetron 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.
Dược Động Học :

▧ Half Life :
The elimination half-life after 4- and 8-mg oral doses administered 3 times daily for 6 days was reported to be 1.6 to 1.9 hours.
Chỉ Định :
For the treatment of symptoms associated with irritable bowel syndrome.
