Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in the control of gastrointestinal (GI) motility, sensitivity, secretion, and regulation of cell growth by the receptors (5-HT1∼5-HT7) on enterocytes, instrinsic enteric neurons, extrinsic afferents, and smooth muscle cells. Functional GI disorder may relate to abnormal 5-HT activities in the gut and brain. Agonists and antagonists of several 5-HT receptor subtypes and agents that prevent 5-HT reuptake have documented benefits in functional GI disorder, however, their usefulness is underestimated by side effects which may or may not relate to their actions on 5-HT receptors. This review focuses on the effects of agents act on the serotonin receptor and agents that modulate serotonin uptake and synthesis and describes their therapeutic potential of these actions with side effects for functional GI disorder.
