Comment From Debbie: Please comment on compounded Omeprazole for ulcers in horses and how do we
know if lab that prepared it made it with effective doses (in individual packets)? Scott Stanley: The best practice is always to use the FDA approved formulation because the quality con-
trol and potency are support by the original pharma company.
Compounding omeprazole is illegal practice as the sole patent is owned by Merial LTD, therefore, the best choice is to use the gastroGard or UlcerGard products.
Comment From Jeffrey Berk: To broaden the discussion from compounded products to unapproved prod-
ucts in general, there seem to be an increasing number of unapproved products masquerading as post-surgical joint lavage “devices”. Clearly, these products are never used as post-surgical joint lavages, but are used IV and IA. Would you comment on the legality of “extralabel” use of unapproved products? Dr. John Tuttle: With the use of any product in an extralabel fashion, ie: not labeled for the intended
purpose, the Veterinarian assumes all liability for the use of that product in that fashion.
TheHorse.com: Kate: Which medications are most often compounded?
Scott Stanley: The “claimed” medical devices used either IV or IA therapeutics are very problematic.
They are, in fact, not “extralabeled usage” simply because they are not actually approved by the FDA so they can’t be used outside of the label claim.
Dr. John Tuttle: At the current time, pergolide mesylate (treatment for PPID/Cushings Dz) is probably
the most commonly compounded product.
Comment From Karen Briggs: Here in Canada, we occasionally have trouble obtaining meds which, for
one reason or another, are no longer allowed across the border. A recent example is Thyro-L, which I For more information on equine health, care and management, visit TheHorse.com

use for my IR pony. If we are forced to switch to a compounded product, how can we best ensure we are buying something safe and with similar levels of active ingredient? Scott Stanley: Ask lots of questions of the compounding pharmacy to establish a relationship and find
out who does the compounding and whetheionship.relatr they will compound already approved FDA products, If they won’t they have established some guidelines from which you can expand your trust.
Comment From Barbara: Tell me about products for ulcer use in horses. Gastrogard/Ulcergard are very
expensive products. What else can a horse owner use which is effective.
Dr. John Tuttle: Gastroguard and Ulcerguard are FDA-approved products for the treatment of ulcers.
With that approval comes proof of efficacy and safety. While there are other anecdotal reports of products which claim to decrease the incidence of ulcers, there is little to no research to back the claim up. I would recommend you discuss alternative treatment options with your veterinarian.
Comment From Jeffrey Berk: So therefore, when a company representative cites “extralabel” use for a
product that is not FDA-approved (like Polyglycan), that type of usage is illegal and can increase legal exposure for the veterinarian using the product in an unlabeled fashion.
Scott Stanley: Yes
Comment From brenda zoppo: If compounded omeprazole is done illegally , how can they get away with it?
Scott Stanley: FDA does not have the resources to shut down ever illegal compounding operation, how-
ever this does not make them a wise or ethical choice, Dr. John Tuttle: Unfortunately there are not available resources to adequately police illegal compounding
of an FDA-approved product. Whenever possible, always use an FDA-approved product indicated for that use. You are assured safety, efficacy, as well as company support.
Comment From Jeannie: What examples can you give of drugs that a vet wouls have to have compounded?
Scott Stanley: Pergolide Mesylate still need to be copounded for the time being.
Comment From Jeffrey Berk: PCAB (the Pharmacy Compounding Accreditation Board) is an organiza-
tion which functions as a form of quality control with regard to compounded medications. Why does PCAB condone the use of bulk product in the formulation of compounded drugs? Comment From Jeannie: What else?
Scott Stanley: Drugs no longer commercially available, Drugs not available on animal health market,
Reformulate drugs into suitable dosage forms Comment From Francesca: What should we look for in compounded antibiotic formulations, for cost
related issues (long term therapy, for example) or for flavoring? thank you Dr. John Tuttle: Antibiotic formulations should only be compounded from FDA-approved products.
Whenever the presentation of the product is changed, you cannot be be assured adequate delivery to your horse. Therefore you should only rely on compounded formulations whenever no other presenta-tion is available for the indicated use of your horse.

LegaL and etHiCaL issues
Scott Stanley: Bulk drugs compounding typically means they use chemical grade and not pharmaceuti-
cal grade raw materials. In addition, the FDA believes this is manufacturing a new drug without their approval.
Comment From Shari Godano: So you are saying it is ok to compound pergolide just because it is not
available? Even though you are suggesting it is not stable? Dr. John Tuttle: At the current time, compounded pergolide is the only available product. The powdered
or capsule form of the product appears to be more stable than the liquid based on stability data.
TheHorse.com: We’ve got some great questions coming in! Give us just a minute to type in the answers. :)
Comment From Jeffrey Berk: Approximately how many different compounded products do you think an
equine veterinarian would need in order to practice quality veterinary medicine? Scott Stanley: There isn’t any right answer but my guess would be variable from 5-7 different products
maximum for any equine practitioner.
Comment From Guest: My (20yr) horse has cushings, we are in the Caribbean. She is on Pergolide which
I purchase from a compounding lab in Florida…she did not respond very well to liquid but the powder has given her a real turn around (she looks great, lab tests not available down here)…should I be con-cerned about my supplier? How do I know if supplier is reputable or not? Jane in Antigua Dr. John Tuttle: Only speculating with your horse, but the stability of the liquid form of pergolide has
been shown to be less than the powder or capsule form. I would stick with the powder form. I would consult with your veterinarian with regards to the reputation of the compounding pharmacy. There are certain questions that he/she can ask, which can be found on the AAEP webite (aaep.org) under compounding.
Comment From Jeannie: If a drug is not available in the animal health market, does that mean it is not
safe in animals? Why would I want to use something that is not appropriate for my animal? Scott Stanley: The drug may have been withdrawn because of a complication with the human market/
product which does not affect the animals being treated.
Comment From Jeannie: Sounds like take home message is don’t use compounded drugs!
Scott Stanley: The use of compounded products need to be more closely considered then when using an
Comment From Bobbi: my horse had been on isoxsuprine tablets for almost a year. However, recently,
my vet had difficulty getting the tablets and now I am using a compounded power. Any comments on isoxsuprine in general? Thanks! Dr. John Tuttle: As long as isoxsuprine is compounded from an FDA-approved source, you should be
Comment From Jeanne: How did that pharmacy manage to stay in business (that contributed to the death
Scott Stanley: The compounding pharmacy responsible was shut down temporarily.

tion on nutritional supplements being compounded? Dr. John Tuttle: Nutritional supplements that do not make a specific medical claim are not regulated by

Comment From Lori: Is Acetyl-D Glucosamine safe to give to my young horse to help with his hocks?
TheHorse.com: Lori: I was told that that the acetyl d glucosamine is compounded and my vet said studies
Dr. John Tuttle: With compounded products, very rarely, if ever, will you have safety and efficacy data, as
compared to FDA-approved products. I am unaware of the studies supporting this.

Comment From Jeannie: But it’s not approved by the FDA
Dr. John Tuttle: That is correct.
Comment From Shari: Aren’t certain states allowed to have compounded meds for “office use”?
Scott Stanley: “Office use” means they can keep a portion on hand but not that they can compound any-
TheHorse.com: Hi Jeannie! Supplements and medications have two different regulatory situations; here
is some information on supplement regulation: I was told that that the acetyl d glucosamine is com-pounded and my vet said studies have been positive with its use.
Comment From Jeanne: I have little choice but to use compounded pergolide (capsules) for my Cushings
horses. The pharmacy I get it from is recommended by my vet, but how do I really know I’m getting what is labeled - is there any on-line resource “grading” compounding pharmacies? Scott Stanley: The best way is to monitor the horses progress and track with the drug response and al-
ways make sure to replace the product frequently (don’t order large quanitites).
Comment From James: why can’t compounders use bulk chemicals for horses? they are allowed to use

LegaL and etHiCaL issues
Dr. John Tuttle: Whenever there is an FDA-approved product available, compounded products should be
manufactured from the parent product. In only rare circumstances will FDA/CVM allow regulatory descretion with regards to the use of bulk product. An example is pergolide.
Comment From Shari: Thank you!

Comment From Jacquelin: How do these people get away with putting these compounded meds on the
market? Why are they not fined and/orput in jail? Scott Stanley: The compounders are not violating any criminal laws so they won’t go to jail at worst they
will be shut down and have their product taken by the FDA.

Comment From Francesca: thank you. Good webinar
TheHorse.com: Thank you Francesca! We’re glad you enjoyed it. :)
Comment From Jacquelin: I fail to understand how pergolide is supposed to help Cushing’s horses in the
first place. It is not used for humans any longer.
Dr. John Tuttle: Pergolide was used in the treatment in humans for Parkinsons dz. it no longer marketed
in the US for this purposes. While the mode of action is similar in both horses and humans, the end results, with regards to hormonal requlation is quite different. It still is considered the treatment of choice for PPID in horses.
Comment From mindy: in the omeprazole paste graph, one pharmacy actually exceeded the manufactured
Scott Stanley: The same product rapidly deteriorated which may explain why the compounder choose to
