Abstract
Biochemical modifications and local delivery methods may enhance drug transport across the blood-brain barrier (BBB) for central nervous system diseases.
- Methods such as focused ultrasound and microbubbles could disrupt the BBB to facilitate drug delivery.
- Targeting receptors that allow transport across the BBB may enable noninvasive delivery of both small molecule and biological cancer therapies.
- Local delivery techniques could allow for high doses while minimizing systemic exposure.
- Clinical trials indicate potential for these innovative approaches but highlight ongoing challenges in CNS drug development.
