- Pharmacodynamics
GlaxoSmithKline was investigating piboserod, a 5HT4 antagonist, for the treatment of atrial fibrillation. Phase II trials were ongoing in March 2004, but by December of that year, development had been discontinued. Piboserod had previously being investigated for the treatment of irritable bowel syndrome (IBS), but development for this indication was terminated in 1999.
- Mechanism of action
Piboserod appears to act as a specific antagonist of one of the receptors for 5-hydroxytryptamine, the 5-HT4 receptor. The 5-HT4 receptor antagonists are thought to antagonize both the ability of serotonin to sensitize the peristaltic reflex and 5-HT-induced defecation, at least in animal studies. As 5-HT4 receptors are present in human atrial cells and when stimulated may cause atrial arrhythmias, piboserod was under investigation in clinical trials for atrial fibrillation.
