Abstract

In summary, many of the most promising preclinical data on novel approaches to improve antiepileptic drug delivery are aimed at either disrupting or bypassing the BBB, including Trojan horse technology that would allow targeting of large (and water insoluble) molecules through the BBB to epileptic brain regions responsible for seizure generation. The most important aspect is that such novel delivery approaches will allow clinical testing for antiepileptic activity of large molecules that were previously barred from development of epilepsy drugs. There may be a whole new world of effective epilepsy drugs that were excluded from experimental, and clinical evaluation simply because they could not cross the BBB. Researchers and practitioners in the field eagerly await the results—with cautious optimism and with high hopes.
