• Indian scientists have developed a novel nose-to-brain drug delivery method for treating Central Nervous System Tuberculosis (CNS-TB), a severe form of the disease.
• The method utilizes chitosan nano-aggregates to transport TB drugs directly to the brain, bypassing the blood-brain barrier and improving drug bioavailability.
• In mice studies, nasal delivery of nano-aggregates significantly reduced bacteria in the brain compared to untreated subjects, demonstrating therapeutic effectiveness.
• This approach could potentially be applied to treat other brain infections, neurodegenerative diseases, brain tumors, and epilepsy by enabling efficient drug delivery.
