Convection-Enhanced Delivery (CED)
Direct brain drug delivery bypasses the blood–brain barrier using catheter-based convection-enhanced methods
30 Jan 2026
0
What is the primary advantage of convection-enhanced delivery (CED) over conventional drug delivery methods for treating central nervous system diseases?
CED relies on diffusion to spread drugs evenly throughout the entire brain tissue.
CED bypasses the blood–brain barrier and allows targeted drug delivery to specific brain regions using bulk flow.
CED delivers drugs systemically through the bloodstream to reach the brain indirectly.
