Grapiprant is primarily used in veterinary medicine as a non-steroidal anti-inflammatory drug (NSAID) specifically designed for dogs. It is effective in managing pain and inflammation associated with osteoarthritis, a common condition in older dogs. By selectively targeting the EP4 prostaglandin receptor, it helps reduce discomfort and improve mobility without the gastrointestinal side effects often seen with traditional NSAIDs. This makes it a safer option for long-term management of chronic pain in pets. Additionally, its targeted action minimizes the risk of adverse effects on the kidneys and liver, which is particularly beneficial for dogs with pre-existing conditions.
