Serotonin antagonist

From Wikipedia, the free encyclopedia

A serotonin antagonist acts to inhibit the action at serotonin receptors.

Many of the most important medications of this class selectively act at the 5-HT3 receptor, and thus are known as 5-HT3 antagonists. However, other drugs such as ketanserin act upon other types of serotonin receptors.
