Measurement of Drugs in Microdialysates 06/04/2016 11:40

RenaSci have recently joined forces with pharm-analyt to offer our clients a new service – measurement of drugs and neurotransmitters in the same microdialysate sample.   

Pharm-analyt is a fully-independent bioanalytical company based in Vienna, Baden. The company have been measuring small molecules and their metabolites in a variety of biological tissues for over 30 years. For this purpose, they employ state-of-the-art instrumentation including mass spectrometry technology. This enables them to quantify drug concentrations in minimal sample volumes with very high sensitivity. 

RenaSci employs dual-probe microdialysis to measure extracellular levels of neurotransmitters in different brain regions of freely-moving rats. For example, we have recently measured the effects of d-amphetamine 0.5 mg/kg sc on dopamine levels in the nucleus accumbens and on acetylcholine levels in the prefrontal cortex. Microdialysate samples from this study were sent to pharm-analyt for analysis. The results show an excellent correlation between d-amphetamine concentrations and dopamine levels in the nucleus accumbens and a weaker though still strong relationship between d-amphetamine concentrations and acetylcholine levels in the prefrontal cortex.

The ability to measure drug concentrations and neurotransmitter levels in the same microdialysate sample provides important information regarding the pharmacodynamics-pharmacokinetic properties of the drug.
