Comprehensive Veterinary Anti Inflammatory Drugs List

Managing your furry friend's pain and discomfort can be a daunting task, especially when it comes to choosing the right medication. Fortunately, there are many effective veterinary anti-inflammatory drugs available.

For mild cases of arthritis and joint pain, non-steroidal anti-inflammatory drugs (NSAIDs) like carprofen and meloxicam are often prescribed. These medications work by blocking the production of prostaglandins, which are hormone-like substances that cause inflammation and pain.

Some common NSAIDs used in veterinary medicine include Rimadyl and Metacam. These medications are available in various forms, including tablets, capsules, and injectables, making them convenient for pet owners.

While NSAIDs are effective, they may not be suitable for all pets, especially those with kidney or liver disease. In these cases, alternative medications like corticosteroids, such as prednisone, may be recommended.

NSAIDs are a type of medication that can be used to relieve pain and inflammation in animals.

All NSAIDs, except for acetaminophen, are antipyretic, analgesic, and anti-inflammatory. They're commonly used to treat conditions like osteoarthritis in dogs and horses, as well as colic, navicular disease, and laminitis in horses.

The use of NSAIDs for perioperative pain in companion animals is a standard practice. They provide symptomatic relief from pain and inflammation, but don't significantly alter the course of pathologic damage.

As antipyretics, NSAIDs reduce body temperature in febrile states, which can improve appetite and provide symptomatic relief. In the EU, NSAIDs have been used in conjunction with antimicrobials to treat acute respiratory diseases in cattle.

Some NSAIDs, including aspirin, naproxen, and ibuprofen, are considered chondrotoxic because they inhibit the synthesis of cartilage proteoglycans. Others, like carprofen and meloxicam, may be considered chondroneutral or even stimulate the production of cartilage matrix.

NSAIDs can be divided into three broad groups: carboxylic acid and enolic acid derivatives, and the COX-2 inhibitors. The carboxylic acid subgroups include salicylates, propionic acids, fenemates, phenylacetic acids, and aminonicotinic acids.

The newer coxib class of selective COX-2 inhibitors has been developed in recent decades, with a checkered track record in human medicine. In veterinary medicine, COX-2 inhibitors like deracoxib, firocoxib, and robenacoxib have become available.

Grapiprant is a novel PGE2 antagonist, acting at the EP4 receptor, and is not a COX-1 or COX-2 inhibitor.

Aspirin is a salicylate NSAID commonly used in humans, but its use in animals is limited due to its potential for gastrointestinal toxicity. It's not recommended for use in dogs or cats.

Phenylbutazone (PBZ) is a pyrazolone derivative used to treat acute laminitis in horses, with dosages ranging from 2.2 to 4.4 mg/kg every 12 hours. PBZ is also used in dogs, but its use is associated with bleeding dyscrasias, hepatopathies, and nephropathies.

Tolfenamic acid is a fenemate NSAID approved for use in the EU and other countries, and is used for fever, postoperative pain, and acute and chronic inflammatory conditions in cats, dogs, cattle, and pigs. Its mechanism of action is not fully understood, but it's thought to inhibit COX enzymes.

NSAIDs are a type of medication that can provide relief from pain and inflammation in animals. They are often used to treat conditions such as osteoarthritis in dogs and horses.

All NSAIDs, except for acetaminophen, are antipyretic, analgesic, and anti-inflammatory. This means they can help reduce fever, ease pain, and reduce inflammation.

In veterinary medicine, NSAIDs are commonly used to manage severe pain, especially when combined with an opioid. They're also used to treat conditions like colic, navicular disease, and laminitis in horses.

Some NSAIDs, like aspirin, naproxen, and ibuprofen, can be chondrotoxic, which means they can harm cartilage cells. On the other hand, carprofen and meloxicam may be considered chondroneutral or even stimulate cartilage production.

Carprofen, in particular, has been shown to be effective in managing pain and inflammation in dogs. It's available in various formulations, including caplets, chewable tablets, and an injectable form.

Mavacoxib, another NSAID, has a unique dose regimen due to its long half-life of 17 days in young dogs. This means it's only given once a month for up to seven doses, or around six and a half months.

As with other NSAIDs, carprofen and mavacoxib can have potential side effects, such as gastrointestinal issues and liver damage. However, these are relatively rare and can be managed with proper monitoring and care.

Specific NSAIDs are divided into three broad groups: carboxylic acid and enolic acid derivatives, and the COX-2 inhibitors. Carboxylic acid subgroups include the salicylates (aspirin), propionic acids (ibuprofen, naproxen, carprofen, ketoprofen, and vedaprofen), fenemates (tolfenamic and meclofenamic acids), phenylacetic acids (acetaminophen), and aminonicotinic acids (flunixin).

The propionic acid derivative ketoprofen is available in the US and other countries as a 10% injectable solution for horses, and in the EU and Canada as tablets and a 1% injectable solution for dogs and cats. It's used for acute pain in dogs and cats, and for pain and inflammation associated with osteoarthritis and colic in horses.

The fenemate tolfenamic acid is approved for use in the EU and other countries, and is used for fever, postoperative pain, and acute and chronic inflammatory conditions in cats, dogs, cattle, and pigs. It's also a structural analogue of flunixin.

Flunixin is a nonselective COX inhibitor, and is approved for use in horses as oral and parenteral formulations in the US. It's used for the treatment of musculoskeletal inflammation and visceral pain associated with colic in horses.

Meloxicam is a potent inhibitor of prostaglandin synthesis, and is used for the treatment of acute and chronic inflammation associated with musculoskeletal disease and for the management of postoperative pain. It's approved for use in dogs, cats, cattle, pigs, and horses in the EU and other countries.

Vedaprofen is an arylpropionic acid derivative, and is available in the EU in a gel formulation for horses and dogs and in an injectable formulation for horses. It's used for the treatment of pain and inflammation associated with musculoskeletal disorders in dogs and horses.

Firocoxib is a coxib-class NSAID, and is approved for the control of pain and inflammation associated with osteoarthritis and for the control of postoperative pain and inflammation associated with soft-tissue and orthopedic surgery in dogs. It's also approved for use in horses for the treatment of osteoarthritis.

Grapiprant is a novel PGE2 antagonist, acting at the EP4 receptor, and is not a COX-1 or COX-2 inhibitor.

Ibuprofen is not recommended for use in dogs or cats due to their increased sensitivity to gastrointestinal adverse effects.

Indomethacin is highly toxic to a dog's GI tract and can cause severe ulceration, hematemesis, and melena at therapeutic doses.

Piroxicam undergoes extensive enterohepatic recycling in dogs, resulting in a prolonged plasma half-life and increased risk of gastrointestinal ulceration and bleeding.

Dogs receiving piroxicam at dosages of 0.3–1 mg/kg per day may experience gastrointestinal ulceration and bleeding, as well as renal papillary necrosis.

Naproxen has been used in horses at a dosage of 5–10 mg/kg, once to twice daily, but its bioavailability is lower in horses compared to other NSAIDs.

The elimination half-life of naproxen in horses is approximately 5 hours, whereas in dogs, it ranges from 35 to 74 hours.

Dogs are extremely sensitive to the adverse effects of naproxen due to its prolonged half-life, making it essential to exercise caution when administering this medication.

Celecoxib and valdecoxib, COX-2 selective drugs, have shown reduced incidence of gastrointestinal ulceration in human patients compared to naproxen, but their use in animals has not been fully investigated.

NSAIDs are weak acids that are well absorbed after oral administration, but food can impair their absorption in some cases.

Most NSAIDs are highly protein-bound, with up to 99% of the drug bound to plasma proteins, leaving only a small proportion available to be active in the tissues. This means that they tend to concentrate in areas of inflammation, making their duration of action typically exceed their elimination half-life.

Some NSAIDs, such as mavacoxib, are excreted unchanged in the bile, while others undergo extensive biotransformation in the liver to inactive metabolites that are excreted by the kidney or bile.

Here's a list of some key characteristics of NSAIDs:

It's worth noting that age and species variation plays an important role in the pharmacokinetics of NSAIDs, making it difficult to safely extrapolate dosages from one species to another.

NSAIDs are weak acids that are well absorbed after oral administration, but food can impair the absorption of some NSAIDs, such as phenylbutazone, meclofenamate, flunixin, and robenacoxib.

Most NSAIDs are highly protein bound, with up to 99% of the drug bound to plasma proteins, leaving only a small proportion of unbound drug available to be active in the tissues.

Some NSAIDs are available as parenteral formulations for intravenous, intramuscular, or subcutaneous administration, but these formulations can be highly alkaline and may cause tissue necrosis if injected perivascularly.

NSAIDs are biotransformed in the liver to inactive metabolites that are excreted either by the kidney via glomerular filtration and tubular secretion or by the bile, except for mavacoxib, which is mostly excreted unchanged in the bile.

The elimination half-lives of NSAIDs vary significantly by species, and in some cases, by breed or strain, such as with some COX-2 inhibitors in Beagles.

Here are some key pharmacokinetic properties of NSAIDs:

It's worth noting that some NSAIDs, such as naproxen, undergo extensive enterohepatic recirculation in some species, resulting in prolonged elimination half-lives.

Aspirin is a salicylate and a carboxylic acid derivative, commonly used in humans for its anti-inflammatory properties.

The newer coxib class of selective COX-2 inhibitors, such as celecoxib, has been developed for use in human medicine, but its use in animals has yet to be fully investigated.

Carprofen is a propionic acid derivative and a nonsteroidal anti-inflammatory drug (NSAID) used in veterinary medicine.

Ibuprofen is an arylpropionic acid derivative used in dogs as an anti-inflammatory agent, but dogs are much more sensitive to its gastrointestinal adverse effects than humans.
