[Influence of serotonin (5-HT) 2A-receptor and transporter (5HTT) gene polymorphism upon the effect of olanzapine]

Abstract

We investigated the relationship between the genetic polymorphism (s/l) of 5-HT2A receptors (A-1438G) and 5-HTT (s/l), and the drug effects among 31 patients who are administering olanzapine, as a help of the tailor made medical care in a time. As for the genetic polymorphism of 5-HT2AR, G/G group showed a significantly improvement tendency in the PANSS positive syndrome score in comparison with the group which did not have a G gene (AA and AG). It may be possible that this finding help to predict the drugs effect of olanzapine on the patients with excite state, who are used many antipsychotics together out of necessity.
