After scientific research verified the painkiller nimesulide’s harmful effects on vultures, an endangered species, India bans nimesulide formally prohibiting it. Under Section 26A of the Drugs and Cosmetics Act of 1940, the Central Drugs Standard Control Organisation (CDSCO) published a notice in the gazette that forbade the production, distribution, and sale of any medication formulations containing nimesulide. The Central Government and the Drugs Technical Advisory Board were consulted before making the decision. Small dosages of nimesulide produced renal toxicity in Gypsy vultures, which resulted in serious health problems and population decreases, according to research from the Indian Veterinary Research Institute.

Nimesulide’s Role in Vulture Mortality and Alternatives

In India, the use of nimesulide in veterinary medicine has been connected to dead vultures, which are frequently observed exhibiting symptoms of visceral gout. Its harmful effects were confirmed by captive vulture experiments, which strengthened the case for its prohibition. India bans nimesulide as a non-steroidal anti-inflammatory medicine (NSAID) due to these findings, despite its widespread use to reduce pain and inflammation globally. Safer substitutes, such as tolfenamic acid and meloxicam, have been identified and are recommended for use in veterinary medicine. At dosages that vultures could experience in the wild, these alternatives are safe for them.

The former prohibition of diclofenac, another NSAID connected to severe renal failure and vulture mortality, set the foundation for the current restriction on nimesulide. Diclofenac was prohibited for veterinary use in Bangladesh in 2010 and in India, Pakistan, and Nepal in 2006 due to the organ damage it caused in a matter of days. Due in part to these prohibitions, Nepal partially recovered and slowed down vulture declines.

Broader Implications for Wildlife and Livestock Health

Animals with osteoarthritis, such as dogs, were frequently treated with nimesulide to reduce pain and inflammation. It controls inflammation, inhibits immunological responses, and targets COX-2 enzymes. However, experts pointed out that it poses threats to wildlife and is inappropriate for animals with liver or renal problems. To lessen damage to cattle and wildlife, authorities have urged the greater use of safer substitutes.

The government’s decision to outlaw nimesulide emphasizes how important it is for veterinarians to practice ecologically conscious medicine. In order to safeguard India’s endangered animals and encourage the use of drugs that are safe for wildlife, this decision is essential.
