Levetiracetam (LEV) is a newly developed antiepileptic drug (AED) with a broad spectrum of efficacy against partial and generalized seizures. [1]
The mode of action of LEV seems to be different from other AED. Synaptic vesicle protein 2A which can block calcium release from intraneuronal stores is shown to be the binding site of levetiracetam. Thus, it works against the negative modulators of gamma-aminobutyric acid and glycin-gated currents. Moreover, LEV does not have the ablility to induce cytochrome P450 isoenzyme.[2]
A study has shown that an oral dose of LEV can’t bind to plasma proteins, while no hepatic metabolism was observed. One-third of the metabolized drug was found to be hydrolyzed and the others were excreted unchanged in the urine.[3]

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

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.
