FAQs

Is Polyglycan a generic product?

No. Polyglycan® is a patented 3-component formula which has demonstrated characteristics beyond any of these components used individually. Polyglycan is specifically formulated to have the same viscosity and lubricating properties as natural equine synovial fluid.

Is Polyglycan considered a medical device or a drug?

Polyglycan is a medical device – it achieves therapeutic effect by mimicking the physical properties of equine synovial fluid. The mechanical lubrication and cushioning provided by Polyglycan helps by protecting the joint in a non-chemical/non-metabolic manner.

Is Polyglycan manufactured in an FDA-registered facility?

Yes! The Polyglycan manufacturing facility achieved Current Good Manufacturing Practice (CGMP) status over 10 years ago, and is routinely inspected by FDA.

Are products similar to Polyglycan ever used in humans?

Yes! In fact, all hyaluronic acid products currently used in humans for intra-articular joint treatments are also medical devices.

What is a medical device?

FDA determines a medical device as: "an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is:

  1. recognized in the official National Formulary, or the United States Pharmacopoeia, or any supplement to them,
  2. intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals, or
  3. intended to affect the structure or any function of the body of man or other animals which does not achieve its primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of its primary intended purposes.”

What are the label claims for the uses of Polyglycan?

Polyglycan is specifically formulated to mimic the physical properties of normal equine synovial fluid. The product’s intended use is in the synovial space (directly in the joint) in horses as a post-surgical lavage, a synovial fluid replacement, or as a viscosupplement.

I use Polyglycan exclusively (other than biologics) in joint therapy. In other words, Polyglycan is my "go to" medication.

I have used Polyglycan since 2010.  Since then our clinic has used over 70,000 doses in both post-surgical and treatment of typical inflammatory conditions of the joint.  In my experience, I have very good to acceptable outcomes using Polyglycan in routine joint therapy.  Additionally, we have not experienced the occasional joint flair seen in other products.  We have not had any problems with any type of proliferative arthritic conditions.  Currently, I use Polyglycan exclusively (other than biologics) in joint therapy.  In other words, Polyglycan is my "go to" medication.

"In the treatment efficacy portion, joints of Polyglycan® treated horses had fewer microscopic articular cartilage abnormalities as well.

There has apparently been no report of any clinical or radiographic consequences in this location with clinical use in the horse.”

Polyglycan is administered intra-articularly and intravenously in my pracitce. I administer Polyglycan intra-articularly during and after joint surgery, and the horses are administered Polyglycan weekly for, at least, 4 weeks after surgery

"Polyglycan (hyaluron, sodium chondroitin, N-acetyl-D-glucosamine) is administered in my practice. I administer Polyglycan during and after joint surgery (arthroscopy or arthrotomy), and the horses are administered Polyglycan weekly for, at least, 4 weeks after surgery, if financially feasible. A large part of my practice is arthroscopic removal of OCD lesions and chip fractures in Thoroughbred yearlings. The vast majority of these joints do not have radiographic or clinical signs of osteoarthritis prior to surgery. I routinely perform post-operative films within 30 days after surgery, and a large number of these horses have radiographs taken for use at auction several months after surgery. I have not observed osteophyte formation after administering Polyglycan in these cases for the past 9 years.

In my opinion, there is decreased joint morbidity in the cases where Polyglycan is administered after surgery versus the cases that do not receive Polyglycan. I also observe decreased joint morbidity and quicker resolution of effusion in the race horses and yearlings that have clinical and radiographic evidence of osteoarthritis prior to surgery."

Polyglycan® is the primary product for joint injections in my equine practice since 2006.

Polyglycan® has been administered extensively to horses competing in a variety of disciplines. This population includes professional rodeo horses, cutting horses, reining horses, working cow horses, racehorses, and horses in the English disciplines ... We’ve used over 50,000 mL of Polyglycan® in our practice giving us a high level of comfort and confidence in its applications. To date there have been no adverse events to be reported by our clients or our practice. Through my peer group I have not had conversations to suggest that their experience has been different.

I have continued to use Polyglycan as a standard postoperative parenteral treatment as well for essentially all of my orthopedics.

"I began using Polyglycan in a clinical setting over 10 years ago, initially as a post-surgical lavage following arthroscopic surgery. Soon afterward I began routine administration on a weekly or bi-weekly basis on athletes with musculoskeletal maintenance issues as well as young developing horses with developmental orthopedic disease. I have continued to use Polyglycan as a standard postoperative treatment as well for essentially all of my orthopedics. I have encountered no adverse effects from either route of administration of Polyglycan.

In addition to using Polyglycan in racing athletes and sport horses, I routinely recommend its use in weanlings and yearlings with synovitis and joint effusions that are the result of osteochondrosis lesions. I also frequently administer Polyglycan in foals undergoing treatment for septic arthritis. I have not experienced any adverse reactions with the use of Polyglycan."
