Brain-targeted drug delivery is a field of research that seeks to develop new methods for delivering drugs the brain. This done by overcoming blood-brain barrier (BBB), network cells tightly regulate flow substances between blood and Most time lipophilic are easily cross brain but few them less soluble in lipid therefore they don’t barrier. After review we concluded can improve solubility using...
