Geodon is an atypical anti-psychotic and tranquilizing agent with multiple mechanisms of action. The drug is an antagonist at dopamine D2, serotonin 5HT1D and 5HT2A receptors, and an agonist at serotonin (5HT1A) receptors. Geodon also moderately inhibits re-uptake of norepinephrine and serotonin and has anti-histamine activity. This drug has fewer documented side effects - including extrapyramidal symptoms - than typical antipsychotics such as haloperidol.
