Clinical Detail From Health Canada Resources

In more clinical terms, Zyprexa acts as an atypical antipsychotic, exerting its effects mainly through antagonism of dopamine D2 and serotonin 5-HT2A receptors. Detailed pharmacodynamics can be reviewed through Health Canada resources for those interested in more in-depth information about how this medication interacts with brain chemistry.
