Background:

Olanzapine is a high affinity for 5-HT2 serotonin and D2 dopamine receptor antagonist.


The 5-HT2 serotonin and D2 dopamine receptor s are subfamily of G protein-coupled receptors(GPCRs) [1].


In vitro: Binding studies showed that olanzapine interacted with keyreceptorsof interest in schizophrenia, exihibiting a nanomolar affinity for dopaminergic, serotonergic, alpha 1-adrenergic, and muscarinic receptors [1].


In vivo: Olanzapine was a potent antagonist at DAreceptorsand 5-HT receptors, but showed weaker activity at alpha-adrenergic and muscarinic receptors [1].Administration of Olanzapine at 0.5, 3 and 10 mg/kg (s.c.) increased the extracellulardopamine(DA) and norepinephrine (NE) levels in all three brain areas in a dose-dependent manner.The increases reached peaks 60-90 min after olanzapine administration and lasted for at least 2 h. The highest DA increases in the Acb and Cpu were induced by olanzapine at 3 mg/kg but at 10 mg/kg in the Pfc while the highest NE increase in the Pfc (414% ± 40) induced by 10 mg/kg olanzapine [2].In macaque monkeys, olanzapine treatment resulted in an 8-11% reduction in mean fresh brain weights as well as left cerebrum fresh weights and volumes [3].
