What is it about?

Dimethyl sulfoxide (DMSO) is a widely used solvent for water-insoluble molecules and it has antioxidant, neuroprotective and cryopreservative effects. While DMSO is a regularly used solvent in research and a therapeutic agent, several cases of DMSO evoked seizures were reported in the literature. Therefore, we investigated the effect of different doses of DMSO on the absence-like epileptic activity of Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats.

Why is it important?

We revealed that low doses of DMSO decreased whereas high doses of DMSO increased the absence-like epileptic activity of WAG/Rij rats.

Perspectives

As DMSO can modify the effects of the different antiepileptic drugs, particular care should be taken when evaluating the actions of these drugs administered in DMSO.
