Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
5-HT2 [1]
D2 receptor [1]
In vitro

Olanzapine interacts with key receptors of interest in schizophrenia, having a nanomolar affinity for dopaminergic, serotonergic, alpha 1-adrenergic, and muscarinic receptors. This compound has a receptor profile that is similar to that of clozapine: it is relatively nonselective at dopamine receptor subtypes and it shows selectivity for mesolimbic and mesocortical over striatal dopamine tracts (electrophysiology; Fos). [1]

In vivo

Olanzapine is a potent antagonist at DA receptors (DOPAC levels; pergolide-stimulated increases in plasma corticosterone) and 5-HT receptors (quipazine-stimulated increases in corticosterone), but is weaker at alpha-adrenergic and muscarinic receptors. [1] This compound combined with fluoxetine produces robust, sustained increases of extracellular levels of dopamine ([DA](ex)) and norepinephrine ([NE](ex)) up to 361% and 272% of the baseline in rat prefrontal cortex, respectively, which are significantly greater than either drug alone. [2] It at 0.5 mg/kg, 3 mg/kg and 10 mg/kg (s.c.) dose-dependently increases the extracellular dopamine (DA) and norepinephrine (NE) levels in rat prefrontal cortex, nucleus accumbens and striatum. This chemical also increases extracellular levels of a DA metabolite, DOPAC, and tissue concentrations of a released DA metabolite, 3-methoxytyramine. [3] It results in an 8-11% reduction in mean fresh brain weights as well as left cerebrum fresh weights and volumes in macaque monkeys. [4] This agent results in substantial increases in adiposity: increased total body fat reflecting marked increases in subcutaneous and visceral adipose stores. It results in marked hepatic insulin resistance. [5]
