Scientists use nanotech to 'upgrade' TB drugs

Abstract:
South African scientists have used nanotechnology to enhance the absorption of tuberculosis (TB) drugs in the body so that fewer, smaller doses are needed.

Clinical trials for the antibiotic, Rifanano — a combination of the four main first-line TB drugs — are scheduled for 2012 and the drug should be available in government clinics in 2016, Hulda Swai, principal researcher in biomaterials research told SciDev.Net.

The new drug is coated with nano-sized particles which are in turn coated with chemicals that make them stick to the intestine wall, enabling the drug to be far more easily absorbed.
