Nanocarriers-based therapeutic strategy for drug-resistant epilepsy: A systematic review

Background

Nanocarriers have been proposed as a solution for drug-resistant epilepsy.

Methods

A systematic review of animal and in vitro studies was conducted to evaluate the efficacy, toxicity, and biological properties of nanocarriers. Searches were performed in PubMed/Medline and Scopus from March 2023 to March 2024.

Results

Eighteen studies were identified: 2 in vitro, 9 in vivo, and 7 combined. While epilepsy models and seizure control assessments were consistent, there was variability in evaluating the potential toxicity of nanocarriers. Only one study did not show a reduction in brain inflammation, seizures, and cell loss. Nanocarrier toxicity was evaluated just in six studies, all of which indicated low toxicity both in vitro and in vivo.

Conclusions

Nanocarriers with antiseizure drugs manage seizures, inflammation, oxidative stress, and behavior impairment in drug-resistant epilepsy. Furthermore, nanocarriers are a safe option for delivering antiseizure drugs, though more research is needed to confirm these findings.
