Understanding the Blood-Brain Barrier
The blood-brain barrier (BBB) is a highly selective semipermeable border that separates the circulating blood from the brain and extracellular fluid in the central nervous system. It plays a crucial role in protecting the brain from harmful substances, but it also presents a challenge for delivering therapeutic drugs to the brain. The BBB is composed of endothelial cells that are tightly packed together, making it difficult for large molecules and most medications to pass through.
Challenges in Drug Delivery to the Brain
One of the main challenges in drug delivery to the brain is finding a way to bypass the BBB without causing damage or compromising its protective function. Traditional methods of drug delivery, such as oral ingestion or intravenous injection, are often ineffective for brain-related conditions. Additionally, the systemic delivery of drugs can lead to off-target effects and diminished therapeutic efficacy.
