What is "naproxcinod"

Naproxcinod (nitronaproxen) is a non-steroidal anti-inflammatory drug (NSAID) developed by the French pharmaceutical company NicOx. It is a derivative of naproxen with a nitroxybutyl ester to allow it to also act as a nitric oxide (NO) donor. This second mechanism of action makes naproxcinod the first in a new class of drugs, the cyclooxygenase inhibiting nitric oxide donators (CINODs), that are hoped to produce similar analgesic efficacy to traditional NSAIDs, but with less gastrointestinal and cardiovascular side effects.

On December 2006, Scientific American distinguished naproxcinod as one of the ten most promising treatments for the world's biggest health threats; however, in 2010 the U.S. Food and Drug Administration determined that further clinical trials would be needed to obtain approval.
