What Is Galliprant?
Galliprant is a first-of-its-kind targeted pain reliever for osteoarthritis in dogs. It comes in a flavored chewable tablet that's administered daily and can be used during all stages of arthritis. Dogs won't develop a tolerance to Galliprant, which means it can be used for as long as necessary and consistently deliver pain relief. It's approved for use in dogs that weigh more than eight pounds and are nine months of age or older.1
Active Ingredient & Mechanism Of Action
Galliprant's active ingredient is grapiprant, a selective non-steroidal anti-inflammatory drug (NSAID) that specifically targets the EP4 receptor. Prostaglandins, naturally occurring compounds in the body, regulate pain and inflammation. They're released in response to injury, causing redness and swelling. Of the four receptors involved in the body's pain reaction, the EP4 receptor plays a primary role in canine arthritis pain and inflammation. By targeting only the EP4 receptor, Galliprant ensures pain relief while permitting the other prostaglandin receptors to function normally.2
Conventional NSAIDs, such as ibuprofen and naproxen, are non-selective. They block both COX-1 and COX-2 enzymes, preventing pain signals from reaching the brain. While these enzymes are prostaglandins and bind to their receptors, blocking COX-1 can lead to blood clotting issues and stomach lining complications. On the other hand, while COX-2 selective inhibitors primarily target inflammation, they've been associated with severe side effects like heart attacks, strokes, and liver damage, leading to many being withdrawn from the U.S market.3 Galliprant, focusing solely on the EP4 receptor, effectively manages pain without the associated risks of COX-1 and COX-2 inhibitors.4
Galliprant chewable tablets are typically beef-flavored to make them more palatable and appealing for dogs, facilitating easier administration by pet owners.1
Galliprant is a specialized medication commonly prescribed for the treatment of osteoarthritis pain and inflammation in dogs.
Joint pain, particularly from conditions like osteoarthritis, can significantly impact a dog's quality of life. It can limit their mobility, decrease their enthusiasm for activities they once loved, and lead to noticeable behavioral changes. Continuous discomfort can make them more irritable or withdrawn, changing the dynamics of their relationship with their human companions and other pets in the household. Addressing joint pain not only eases their physical discomfort but also ensures their emotional and behavioral well-being.1
Some of the more common side effects associated with Galliprant use in dogs include:
- Decreased appetite
- Soft stool
- Incoordination or stumbling
Less common side effects include gastrointestinal ulceration or bleeding, liver or kidney issues, and allergic reactions.
Contact your vet immediately for assistance if you see your dog exhibiting any of these side effects.
Galliprant comes in strengths of 20mg, 60mg, and 100mg. It's available in package sizes of 30 and 90 tablets.
According to the manufacturer’s website, the dose for Galliprant is 0.9 mg/lb or 2 mg/kg once daily. You can also provide your dog Galliprant based on the below information, but always consult your vet first.
- Dogs weighing 8 to 15 lbs: Half a 20 mg tablet
- Dogs weighing 15.1 to 30 lbs: One 20 mg tablet
- Dogs weighing 30.1 to 45 lbs: Half a 60 mg tablet
- Dogs weighing 45.1 to 75 lbs: One 60 mg tablet
- Dogs weighing 75.1 to 150 lbs: One 100 mg tablet1
Galliprant is suitable for puppies aged over nine months and weighing more than eight pounds. For extended use, regular monitoring is advisable. It's essential not to combine Galliprant with other NSAIDs, such as carprofen. Store the medication at room temperature, preferably below 86°F.1
What Is Rimadyl?
Rimadyl is an FDA-approved NSAID specifically formulated to alleviate arthritis-related joint pain and post-operative discomfort in dogs. Depending on the severity of pain, it's administered once or twice daily.
Many dogs experience pain relief shortly after their initial dose, with continued improvement over a two-week span. After this period, with consistent dosing at the prescribed intervals, Rimadyl maintains an effective level in a dog's bloodstream for continuous relief. Owners often observe a notable resurgence in their dog's energy, happiness, and mobility after commencing treatment with Rimadyl.5
Active Ingredient & Mechanism Of Action
Rimadyl's active ingredient is carprofen, a medication exclusively used in animals. While Rimadyl inhibits both COX-1 and COX-2 enzymes, it's generally well-tolerated by canines. Its safety profile is underscored by over 25 years of research, and it has been prescribed to nearly 30 million dogs with a solid track record.5
While carprofen's mechanism of action has parallels with grapiprant, it doesn't discriminate between receptors, binding to all equally. Furthermore, it curtails the production of prostaglandins, which are responsible for pain and inflammation.5
Rimadyl offers multiple administration options to suit various needs. It's available in palatable chewable tablets for easy dosing, traditional caplets for those dogs that might be treat-wary, and an injectable form ideal for immediate relief, often used post-operatively.5
Rimadyl is chiefly prescribed to alleviate pain and inflammation stemming from arthritis, fever, and post-surgical discomfort. In a comparison between Galliprant vs. Rimadyl for dogs, Galliprant is primarily used for a specific purpose, whereas Rimadyl boasts a broader range of applications.5
The side effects of Rimadyl include:
- Loss of appetite
- Urinary incontinence
- Black or tarry stools
- Increase or decrease of thirst
If you observe any of these side effects after administering Rimadyl to your dog, please get in touch with your veterinarian for assistance.
The right Rimadyl dosage is based on your dog's weight. Your vet will assist your dog in finding the best dose, considering their current health, medical history, and more.
According to the manufacturer, here's the recommended dosing for chewables and tablets:
- Dogs weighing 5 to 10 lbs: Half a 25 mg tablet
- Dogs weighing 11 to 15 lbs: One 25 mg tablet
- Dogs weighing 16 to 20 lbs: Half a 75 mg tablet
- Dogs weighing 21 to 30 lbs: Half a 100 mg tablet
- Dogs weighing 31 to 40 lbs: One 75 mg tablet
- Dogs weighing 41 to 60 lbs: One 100 mg tablet
- Dogs weighing 61 to 90 lbs: One and a half 100 mg tablets
- Dogs weighing 91 to 120 lbs: Two 100 mg tablets5
Rimadyl should not be given to dogs with known hypersensitivity to carprofen or other NSAIDs. It is also not recommended for dogs with pre-existing liver or kidney disease, or those with a history of gastrointestinal bleeding. Pregnant, nursing, or breeding dogs should only be administered Rimadyl under the direct supervision and advice of a veterinarian.5
Comparing Galliprant And Rimadyl For Dogs
Galliprant acts as a selective inhibitor, targeting a specific pain pathway, whereas Rimadyl is a non-selective NSAID affecting multiple pathways. The key distinction between Rimadyl and Galliprant lies in this mechanism of action. While both medications address osteoarthritis pain, Rimadyl has broader applications for various pain types, whereas Galliprant is specialized for arthritis-related discomfort.
Which Medication Is Right For Your Dog?
Consulting a vet is pivotal in determining the most suitable medication for your dog. In the process of choosing between Galliprant vs. Rimadyl, your vet takes a multi-faceted approach, starting with a thorough diagnosis. This involves a physical examination to pinpoint the root cause of the pain, paired with a review of your dog's medical history to identify any past injuries or conditions that might influence the present ailment.
Your vet will also assess potential allergies or sensitivities to drugs and evaluate any possible drug interactions if your dog is on other medications. The type and severity of pain play a crucial role in dosage determination as well, ensuring that the medication provides relief without being excessive.
Additionally, factors like age, which can affect drug metabolism, and weight, which directly influences dosage, are also considered. Potential side effects of both Galliprant and Rimadyl are weighed against your dog's overall health profile.
Moreover, the cost may also be a factor. If one medication is more affordable than the other, the vet might discuss the pros and cons of each option with you. It's essential to engage in open dialogue with your veterinarian, asking questions to ensure your dog receives the optimal care.
Other Ways To Comfort A Dog In Pain
