Tamil Nadu state government has banned Ketoprofen, a non-steroid anti-inflammatory drug (NSAID) to save
Vulture
Ketoprofen is extensively used for veterinary purposes and as an alternative to banned veterinary painkiller Diclofenac. It is believed that Ketoprofen causes same effect on the vulture population caused by Diclofenac.
Earlier in 2006, Union Government had banned the use of veterinary drug Diclofenac for treating cattle and in September 2015 its sale in multi-dose vial was banned for human use.
Vultures act as scavengers, preying on dead animals as they have a robust digestive system which can even digest disease-causing pathogens found in rotting meat of dead. But they are not able to break down Diclofenac and die of renal failure or kidney after eating carcasses of cattle administered drug.
