How to Use this NSAID to Treat Arthritis in Dogs?


Carprofen is an anti-inflammatory, nonsteroidal, and non-narcotic agent. Carprofen has characteristic antipyretic and analgesic activities. It is the only FDA-approved drug in the United States to take care of arthritis in dogs. The application of this drug to treat inflammation and pain in other animals or birds happens ‘off label.’ You must adhere to the instructions given by the veterinarian regarding the same.

Special Precautions

The drug is a cyclooxygenase inhibitory NSAID and can have renal, gastrointestinal, and hepatic toxicity. It can happen due to the inhibition of the cyclooxygenase enzyme and a decrease in prostaglandin production. The inhibition of the action of these enzymes can often impact the normal functioning of homeostatic functions. Patients who have an underlying disease can have a situation where their conditions worsen due to anti-prostaglandin effects. Therefore, it is ideal to be cautious while using the drug on a diseased pet Vis-à-vis normal pets.

Mechanism of Action

Like other NSAIDs available in the market, Carprofen also helps to stop cyclooxygenase activity. The constitutive cyclooxygenase helps in normal renal and gastrointestinal functions by synthesizing prostaglandins. These have COX-1 as their identifier.

The inducible cyclooxygenase helps in the generation of inflammation-related prostaglandins. These have COX-2 as their identifier. Any alteration or seizure of COX-1 can lead to renal and gastrointestinal toxicity, and for COX-2, it can lead to anti-inflammation. The intensity of action of a specific NSAID can vary from one species to another. Carprofen exhibits a selective inhibition of COX-2 vis-a-vis COX-1. 

Carprofen also helps stop the release of numerous prostaglandins of the inflammatory cell systems that impact chronic and acute inflammatory reactions. These inflammatory cell systems are human rheumatoid synovial cells and rat polymorphonuclear leukocytes. 

Known Drug Interactions

Medications for which caution is advisable if the same is in recommendation with Carprofen include desmopressin, anticoagulants, tricyclic antidepressants, ACE inhibitors, methotrexate, aspirin, loop diuretics, corticosteroids, oral antidiabetics, cyclosporine, insulin, other NSAIDs, highly protein-bound medications, other nephrotoxic medications, dinoprost, dacarbazine, digoxin, or dactinomycin.

Since studies suggest there are cases of interactions of these drugs with Carprofen, you must be cautious while using them together.
