Pain Drug Can Kill Resistant Tuberculosis

Posted Sep 10 2012 6:14pm

An off-patent anti-inflammatory drug that costs around two cents for a daily dose in developing countries has been found by researchers at Weill Cornell Medical College to kill both replicating and non-replicating drug resistant tuberculosis in the laboratory — a feat few currently approved TB drugs can do, and resistance to those is spreading.

Their findings, published online by the journal PNAS, point to a potential new therapy for the more than 500,000 people worldwide whose TB has become resistant to standard drug treatments. But the researchers worry that the effective drug, oxyphenbutazone, may never be tested in TB clinical trials.

Weill Cornell’s Dr. Carl Nathan and his research team found what they call the “completely surprising” ability of oxyphenbutazone to kill drug resistant TB after testing thousands of approved drugs against the bacteria. This repurposing of agents already on the market can lead to quicker testing for new uses.
