Adding vitamin-C to some drugs may help to improve the treatments available to people suffering from diseases that effect the brain, say a team of Italian researchers. The blood-brain barrier helps to protect the brain from potentially harmful molecules by filtering them out of the blood. However, Stefano Manfredini and his colleagues found that Vitamin-C effectively fast tracks certain drugs through the barrier, as well as enabling drugs normally denied entry by the blood-brain barrier to gain access to the brain. Manfredini believes that vitamin-C could be used to smuggle drugs capable of treating illnesses as diverse as viral infections, neurodegenerative diseases, and epilepsy. The blood brain barrier is a major obstacle to scientists as many drugs are unable to pass through it.
