Ritanserin is a serotonin antagonist with possibilities for the treatment of many neurological disorders.

When used together with typical antipsychotics in the treatment of schizophrenia, it is able to decrease negative symptoms and adds some "atypicality" as parkinsonism is slightly decreased.

Ritanserin may also be effective in the prophylaxis of chronic migraine headaches. Its efficacy may be explained by its ability to antagonize 5-HT2 receptors.[1]


Ritanserin acts as a 5-HT2A (Ki=0.45nM) and 5-HT2C receptor (Ki=0.71nM) antagonist, with higher affinity for the former site.[2]
