ABOUT ADEQUAN® CANINE

What is Adequan® Canine? Arrow Up
Adequan® Canine (polysulfated glycosaminoglycan) is the only FDA-approved disease-modifying osteoarthritis drug (DMOAD) for dogs. It is recommended for intramuscular injection for the control of signs associated with non-infectious degenerative and/or traumatic arthritis of canine synovial joints, also known as canine osteoarthritis (OA).
What is a DMOAD? Arrow Up
A disease-modifying osteoarthritis drug or “DMOAD” is a pharmaceutical that’s capable of making a positive impact on altering or reducing the progression of osteoarthritis (OA).1 Adequan® Canine is characterized as a DMOAD because it is clinically proven to modify the disease in addition to treating the signs of OA. This classification distinguishes Adequan® Canine from other pharmaceuticals or therapies designed to treat the signs of osteoarthritis (OA) alone and not the underlying disease progression. Ask your veterinarian about the possible benefits of using a DMOAD for treating your dog’s OA.
Are there age or breed restrictions for Adequan® Canine? Arrow Up
No age or breed restrictions.
Can Adequan® Canine be used in pregnant, breeding or lactating female dogs? Arrow Up
The use of Adequan® Canine in pregnant, breeding or lactating animals has not been evaluated.
How fast does Adequan® Canine work? Arrow Up
It begins to reach a dog’s joint synovial fluid within 2 hours and detectable levels are maintained in the synovial fluid and articular cartilage for up to 3 days (72 hours).2 Consult your veterinarian if you have any additional questions.




WHY USE ADEQUAN® CANINE

Why is it important to TREAT the osteoarthritis disease? Arrow Up
Canine osteoarthritis is a progressive disease happening over time. According to canine osteoarthritis (OA) experts, the optimal management of OA focuses on strategies which can slow down the clock.3 Adequan® Canine is a disease-modifying osteoarthritis drug (DMOAD) which is proven to bind to and help promote key components of the cartilage matrix and inhibit damaging enzymes to help slow OA degradation in synovial joints. By treating the disease early in its cycle, there may be a profound positive impact on the progression and severity of the OA disease cycle over your dog’s lifetime.

A treatment program which focuses only on managing the signs of OA will not address the underlying disease state responsible for causing the disease progression. Consult with your veterinarian to determine the best treatment methods for your dog.
How is Adequan® Canine different from the non-steroidal anti-inflammatory drugs (NSAIDs)? Arrow Up
While NSAIDs are FDA approved drugs for use in dogs, none of the current non-steroidal anti-inflammatory drugs available today are approved as disease-modifying osteoarthritis drugs. They are only approved to help control the pain and inflammation associated with osteoarthritis. Adequan® Canine (polysulfated glycosaminoglycan) is a disease-modifying osteoarthritis drug (DMOAD) that modifies the course of the disease process.
Why did my veterinarian recommend treatment for my dog which only started showing clinical signs? Arrow Up
Adequan® Canine used early, at the first clinical signs of osteoarthritis, sometimes referred to as degenerative joint disease (DJD), slows progression of the disease before cartilage is irreversibly damaged. Adequan® Canine (polysulfated glycosaminoglycan) is the only FDA-approved disease-modifying osteoarthritis drug (DMOAD) that inhibits cartilage loss in a dog’s synovial joint, and may help to:4 Restore joint lubrication, relieve inflammation, and renew the building blocks of healthy cartilage.
How is Adequan® Canine different from products I can buy over the counter? Arrow Up
There are many supplements and over-the-counter products making similar claims to Adequan® Canine. These products and their manufacturing have not been evaluated by the FDA. Adequan® Canine (polysulfated glycosaminoglycan) is the only FDA-approved disease-modifying osteoarthritis drug (DMOAD) for use in dogs and is recommended for intramuscular injection for the control of signs associated with non-infectious degenerative and/or traumatic arthritis of canine synovial joints.




HOW TO USE

How can I learn whether Adequan® Canine may be right for my dog? Arrow Up
Consult your veterinarian on whether Adequan® Canine may be appropriate for your dog’s osteoarthritis. Federal law restricts this drug to use by or on the order of a licensed veterinarian.
When is the best time to start my dog on Adequan® Canine? Arrow Up
Adequan® Canine is beneficial to dogs diagnosed at all stages of OA, but the earlier in the disease cycle it is started, the greater the overall impact for the dog. Adequan® Canine used early, at the first clinical signs of osteoarthritis (OA), can help slow the progression of the disease before cartilage is irreversibly damaged. This may have a profound positive impact on the progression and severity of the OA disease cycle over the dog’s lifetime. Be sure to talk with your veterinarian to discover if Adequan® Canine is right for your dog.
Why is Adequan® Canine administered as a series of injections? Arrow Up
It all has to do with how Adequan® Canine works. While the specific mechanism of action of Adequan® in canine joints is not known, clinical data shows that Adequan® Canine reaches all synovial joints within 2 hours to begin helping to restore joint tissues that are damaged or inflamed — and lasts for approximately 3 days.2 By administering Adequan® Canine twice weekly for up to 4 weeks (maximum of 8 injections), the drug levels are sustained in the synovial joints for an extended period of time —giving the active ingredients time in the joint to help slow the disease progression.
Why did my veterinarian prescribe another series of injections for my dog? What does “maintenance” mean in this context? Arrow Up
Adequan® Canine does not “cure” osteoarthritis. Unfortunately, there is no cure. But Adequan® Canine can help slow the disease progression. When used correctly, it can help extend a dog’s mobility over a lifetime.

After the initial series of injections with Adequan® Canine, it is important for veterinarians and owners to work together to keep monitoring the dog’s joint health and mobility. If time passes and the dog shows clinical signs of osteoarthritis recurrence, a veterinarian will likely repeat the dosing regimen to help get their patient back on track. A veterinarian may refer to these subsequent series of injections as "maintenance."

Adequan® Canine (polysulfated glycosaminoglycan) is recommended for intramuscular injection for the control of signs associated with non-infectious degenerative and/or traumatic arthritis of canine synovial joints.
What is the treatment protocol for a dog starting with Adequan® Canine? Arrow Up
Consult your veterinarian on treatment protocol and whether Adequan® Canine may be an appropriate treatment for your dog.
The literature says use within 28 days and 10 puncture limit, how long past this can it be used? Arrow Up
Guidelines for usage are the following with whichever comes first: The expiration date printed on the bottle or within 28 days of the first puncture with a maximum of 10 punctures.
What is the 28-day expiration based on? Arrow Up
