Tamil Nadu state government has banned Ketoprofen, a non-steroid anti-inflammatory drug (NSAID) to save critically endangered vulture population in the state.

This drug has been banned in the three western districts of state viz in Erode, Coimbatore and Nilgiris where the vulture population is in danger.

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.
