Pharmacy claiming to have no problem getting Pergolide?

She's wrong.

These little companies haven't tried to reorder any yet.


- Unless they have some really shady black market source (not good),
the pharmacies order "raw" (bulk) from drug wholesalers. Drug
wholesalers order from foreign chemical manufacturers (there actually
are some in the US too - for $2 to $3 PER MG - so you know it's not
coming from there!).
- There is no such thing as the "animal version" of a bulk drug. Both
the compounded versions and the human pills were being made from the
same "raw"/bulk drug.

Even the big compounders that were initially saying they had large
supplies and didn't expect any problems with getting the bulk drug
are panicing now.

For your own (or rather, your horse's) safety, if you run into a
pharmacy that says "no problem", ask them who their supplier is. If
they won't tell you, run.


Great Personalized Letter

My letter to Senator McCain

I worked on McCain's first bid for US Senate - though I no longer live in AZ,
thought maybe this might help...


Dear Senator McCain,

Think way back to 1986 - I was that cute redhead at your headquarters in
Phoenix with whom you would flirt on occasion. (All in good fun, and even with
your wife present.) Anyway, I've been telling people for years that I hoped you
would be elected to the highest office so that I could say the President used to
flirt with me. (And of course that meant something before Clinton.)

At any rate, 20 years later and not nearly as cute (and now married to soon to
be retired Lt. Colonel Karl W******), I am writing to ask a favor...

I know you are very very busy, but...

We horse owners are facing a crisis. Pergolide, the only drug that manages
Equine Cushing's disease, has been pulled from the market. For people, there
are other alternatives, but for the horses there are none. A group of over
3,000 of us have signed a petition and sent it to the FDA without satisfactory
response to date. Thousands of horses' lives depend on this drug.

Below is the letter that has been sent along with the contact information; I
am hoping that you can do something to help usher a life-saving response soon.

Thank you,
And best of everything to you.

"Time is running out for these horses. We urge the FDA to immediately
institute the provision for regulatory discretion as detailed in CVM
Program Policy and Guidelines Manual, Guide 1240.4170 by publishing
an exception from the prohibition on compounding from bulk drug with
specific reference to horses with Cushing's Disease as at least an
interim solution. We have fulfilled the requirements for
documentation of impending shortage, documentation of need and
absence of alternatives for horses. To allow even one horse to suffer
needlessly is an outrage. Human pharmacies with generic pills - those

Can I Bring Pergolide into the US from Another Country?

> Can a person physically go to another country and

No, because to be eligible for importation (even if you go yourself
and get it, it's still importation) it has to be an approved drug
that is identical in every way, including product labelling and
language, to the US form of the drug and has to be manufactured
according to US standards. Because there is no longer an "approved"
form of pergolide, you can't bring it into the country without a

What's interesting though is that all the importation rules apply to
**HUMAN** use. Not a peep about drugs for veterinary use. When
omissions in legislation and guidance documents like this occur, the
FDA will typically make a statement either way depending on what they
favor, rather than any legal basis. For example, the DSHEA (Dietary
Supplements Health and Education Act) protected human access to
things like glucosamine, but because it didn't specifically mention
animals there was a push a few years back to ban these things for
animals. In the case of the drug importation laws, odds are they
would declare the opposite - that they really did mean to include
animal drugs in all the importation restrictions.

By not specifically including animals, any action they might take to
stop your husband bringing it in would be subject to legal
questioning in court - but who has the time or money for that! It
might be an interesting test of the system for him to try it though.
Take your vet's prescription with you, marked clearly "for equine
use", buy just a very small amount and see what happens at customs.

Pergolide Action!

Posted by Dr. Kellon to EC List 4/29/2007 Msg #90858

Since the FDA apparently isn't doing it's homework on how much pergolide is out there in any form, I'd like as many people as possible to call 5, 10 or more pharmacies in your local area, ask them if they have any pergolide pills and if they do, how many, what strength. Jot down the date, pharmacy name and how much, if any, they have. Send that information to the "big 5" below, with a cc to me. If you are uncomfortable doing that, please send it to me and I'll forward it identified only by your city/town. [You can enter your results in a comment at the end of this article and it will be forwarded to Dr. Kellon.]

The only legal source in the FDA's eyes is the pills. The sooner we can document they are gone, or about to be, the better.

Update April 26, 2007

Posted to EC List 4/26/2007 Msg #90692

Such as it is, here goes.

The Veterinary side of the FDA (CVM - Center for Veterinary Medicine), did prepare a proposal for an interim solution. I spoke to the officer (that's what they call them at the FDA, "officer") in charge of that. He would not tell me what was in it but did tell me that he had sent it over to FDA "main" for approval. The approval was expected to have occurred by last Friday at the latest (that was the announcement we were expecting) but never appeared. On Tuesday, he said he was hoping to see it "soon".

Part of the problem is priority. They're a tad distracted by the contaminated pet food fiasco ... but even more important is that none of the immediate available options are very appealing to the FDA. Below is a list of the possible solutions that I just put together for a Horse Journal article:

1. The FDA could publish a specific exemption from the prohibition on compounding from bulk drugs with regard to pergolide and horses with Cushing's Disease. This would immediately free drug wholesalers to supply compounders. Drug should still only be produced upon receipt of a prescription from the treating veterinarian. This would be entirely legal and there are precedents for issuing exceptions. Certain chemicals used in treatments of poisonings have already been granted exceptions. We favor this as a short term solution.

2. The former USA manufacturers of pergolide pills in this country could be encouraged to resume production specifically for veterinary use.

3. The FDA could allow importation of pergolide pills produced in other countries.

4. A drug company could begin the drug approval process for pergolide as a treatment for equine PPID. This is time consuming and expensive, but preliminary communications with the FDA CVM staff in the division of MUMS – Minor Uses and Minor Species – indicates they may be able to help. This division was created to help fill the special needs of relatively uncommon species, or uncommon diseases. While the number of horses with Cushing's Disease is certainly not small, the market size can't compare to the need for things like dewormers and antibiotics. The program provides financial incentives and allows for sales of the drug before the entire approval process has been completed.

5. In the event the FDA does not offer even a short term solution
quick enough, and an owner/vet find themselves unable to source the
drug, the veterinarian can apply for a Medically Necessary Veterinary
Drug exception. Details for this application can be found at: Once approved, this would enable the veterinarian to import drug to treat his or her patient(s). Because of inherent delays in petitions being approved, and a likely large volume of petitions once the supply begins to dry
up, you shouldn't wait until the last minute to get started on this.


In speaking with the FDA on Tuesday, it was abundantly clear that
granting an exception for bulk compounding was the last thing they
wanted to do. The current compounding furor, with abuses on both
human and veterinary ends, haven't helped us any. Still, this would
be the quickest solution. The FDA would prefer to see 2. happen, but
no interest from that sector so far. Number 3. is probably the
solution that CVM proposed (I'm guessing at that), but FDA main
wouldn't be wild about that idea either.

Number 4. is something I'm actively working on, identifying companies that are already making "specialty" drugs (smaller market than big sellers like dewormers or antibiotics), small companies, companies with experience producing drugs that are potent in small doses in a loose powder form.

Number 5. is your safety net. There's no way to tell how much
pergolide is still out there, or how long it will last. Pharmacies
that seem to have a good supply now could find it disappearing
quickly as other pharmacies run out. If this drags on too long, you
could also easily be looking at a problem with black market drug of
god knows what quality and coming from god knows where. If the
availability of drug through approved suppliers doesn't change,
sooner or later you're going to have be highly suspicious of anyone
who claims they have no problem getting the drug. The FDA is not
interested in having to process a huge volume of these applications,
but may try to stall on doing anything until they actually start to
get them.

Until they have a solution in front of them that they like, the FDA is going to drag its feet. We need to keep putting pressure on them. All of you who cross-post and generate new signatures on the petition are helping. Several members are also getting breed associations involved and/or getting articles in magazines. I've been interviewed by The Horse, Equus and got a request late yesterday from Horse Illustrated. There will be an article in the next issue of Horse Journal. Also trying to get a national news service to pick it up.

By the way, in response to the reply from the FDA that some of you
got, basically saying it's not their problem and it's up to the
manufacturers to supply the drug, that's not true. No manufacturer is
obligated to make any drug. Few firms would be interested in
this "small" a market, compared to something that the entire equine
population uses on a regular basis.

The FDA does acknowledge that it has the responsibility to prevent or alleviate both real and potential shortages of essential drugs. Read:

This *is* their problem, but it's up to us to see that they deal with
it before even one horse runs out of pergolide.

Plan "B" if US Supply Dries Up (plan ahead)

Posted on EC List 4/28/2007 Msg #90807

Re: Plan B - Pergolide

To stay on pergolide, your vet can apply for a Medically Necessary
Veterinary Drug exception. The details on how to do this are here:

In fact, that pathway was the initial suggestion we got from the FDA
before they realized the magnitude of the problem and decided they
didn't want to process thousands of these applications but if that's
what it takes to make them move, so be it. Please note that your vet,
or presumably your vet's office at least, has to call to request the
necessary forms. They won't send them out to owners. That document is
worth reading. It states that the FDA recognizes they have a
responsibility to get drugs out to the people or animals that need

This process would allow your vet to import pergolide (e.g. from
Canada) for your horse. Price will be higher than compounded, but
nothing like what one member told she just paid yesterday for generic
pergolide pills that she located at a US pharmacy - ***OVER $6.00 PER
MG*** - more than double what she was paying. At 1 mg/day, at current
pricing, a 30 day supply would run about $60

Another alternative, although highly experimental at this point,
would be to try cabergoline (brand name Dostinex) instead. You can
legally order this from a Candian pharmacy, generic version, at a
very low cost, possibly as low as $20/month. I apologize for not
sending out those cabergline files to those that requested them yet.
It was sounding so hopeful for an early solution a while back that I
held off, then got caught up in the pergolide problem again. Will do
that as soon as I finish this post. [If you require information on cabergoline
for your equine patients, please enter a comment at the end of this article
and you will be contacted.]

There are other dopamine agonists also, but we have ZERO information
on what dosages might be appropriate, safety, etc.

Vitex agnus-castus/Chastetree berry: Good track record for
symptomatic control (laminitis, coat quality, etc.) but not all
respond, those that do respond may become refractory to it. Also
concerning that the blood work doesn't necessarily reflect the
clinical improvements.

Now, back to plan A! Don't get too discouraged yet. The FDA is
sensitive to its public image. If it wasn't for the controversy over
compounding, they wouldn't be dragging their feet like they are. It's
not over yet.

Cypro would be 3 steps backwards I'm afraid. Several studies have now

benefits as pergolide.

April 18, 2007 - AAEP is On Board !!!

Posted to EC List 4/18/2007 Msg #90405

Dear AAEP Members:

As you may be aware, the FDA has withdrawn the drug pergolide from
the market for use in humans. In order for the drug to continue to be
available for use in veterinary medicine, the FDA must approve an
exception for pergolide to be used by veterinarians and to be
compounded in bulk quantities.

The AAEP, through its Drug Compounding Task Force, has been in
contact with the FDA, and they are aware of the significant impact of
pergolide's withdrawal from the market on equine medicine. The FDA
Center for Veterinary Medicine is working with its counterpart for
human medicine, the Center for Drug Evaluation and Research, to allow
importation of pergolide for use by compounding pharmacies. The FDA
expects to have an official announcement by the end of this week.

The AAEP will continue to communicate with the FDA on this issue. For
updates, please visit the AAEP Web site at or call the AAEP office at

April 13, 2007 Clarification of Pergolide Supply

>Do you have email correspondence from these
> wholesalers that you can share, as you have letters from the FDA?

Yes, I do, but they're private e-mails (not government agencies) and
I don't have permission to broadcast them...

Without identifying the sender, here is an excerpt:

"...Here is what we know and/or what we suspect might happen.
- the FDA has not told us we cannot import the material so far
- the FDA issued a Human Compliance Policy Guideline (CPG)
about 4 years ago that specifically identified 20+ chemicals that
were banned or restricted for use in compounding due to safety
reasons. Presumably the withdrawal of pergolide for safety reasons
would fall under this CPG due to precedent.
- the FDA issued at Veterinary CPG shortly after the Human
CPG that stated all compounding from bulk chemicals for vet purposes
was illegal. There was talk at the time that they would issue a
short list of approved chemicals but according to people that saw the
list it was limited to chemicals commonly used to treat poisoning.
The FDA frequently cites AMDUCA as the rational for why bulk
chemicals are illegal.
- the judge in the Midland case did rule that vet compounding
from bulk chemicals is legal with the restriction that it be done for
non-food chain animals. Unfortunately, the way the federal district
courts operate this ruling only applies to the states within that
- the FDA routinely asks us to provide intended use (and
names of likely customers) in writing for chemicals we import before
they will allow the chemical to clear customs. Given the withdrawal
for safety reasons in humans and the ban on the use of bulk chemicals
in vet practice it is entirely possible that they could refuse to let
this material into the country or into our hands."

If there was no issue here, why would the FDA be working on a
solution? You can review some of the controversies here:

Maybe large pharmacies with big stockpiles are saying no problem,
maybe some pharmacies import drug directly in quantity and haven't
been stopped (yet). Maybe pharmacies are operating under the
impression that they won't be stopped because they haven't been in
the past (as in the link above), but if suppliers don't stock and
ship, there won't be an issue about whether what they are doing is
legal or not. There will be no supply.

We just have to wait and see what the FDA press release says next

The last I heard from a wholesaler (and this information is a week old
so maybe things have changed), the FDA has not taken any action to stop
movement of pergolide, and really would have no reason to do that since
the legal demand for the drug is gone. The finished product (pergolide
pills) manufacturers have ceased production.

The FDA theoretically could seize pergolide or ban importation, but as
far as I know that has not occurred. The reason the wholesalers are no
longer wanting to carry it is simply that there is no legal avenue for
them to sell it.

The compounding of veterinary drugs from bulk powder like this is
considered illegal by the FDA. There is one court decision that
disagrees with that stance, two that uphold it. The only reason it's
even a point of contention is that the original legislation permitting
veterinary compounding did not specifically mention compounding from
bulk drugs. However, a later Compliance Guideline policy statement by
the FDA specifically prohibits compounding from bulk drugs. To put it
another way, even if the human manufacturers hadn't withdrawn the drug
from the market, it could still be illegal for compounding pharmacies
to make pergolide for equine use from bulk drugs. The reason for this
policy is that compounded drugs are not checked for potency and purity
the way manufactured drugs are. We've already seen multiple times on
this list how that can cause problems.

The wholesalers are caught in the middle. They can't legally sell bulk
pergolide to compounding pharmacies.

The only way around this would be for the FDA to make an exception in
the case of pergolide for Cushing's horses. They might also decide to
try to encourage one of the previous pill manufacturers to start
production again. Until this is sorted out, the other option you and
your vets all have individually is to submit a MNVD request as I
outlined yesterday. Post 90108.

The sooner they start getting these requests, the sooner they'll
realize there's a problem.


Update April 12, 2007 (Includes correspondance with FDA/CVM)

Posted to EC List 4/12/2007 Msg #90108

Below is the early stages of an exchange with the FDA. Bottom line
situation here is that the compounded pergolide most of you rely on
is, according to an FDA policy statement, illegal.

The FDA cannot police every compounding pharmacy, but they can more
easily target the wholesalers. The wholesalers know this. No
wholesale shipments, no drug available to the compounders.

The FDA has proposed two solutions which appear below. One is to
convince the prior pill manufacturers to produce the drug for
veterinary use. This hasn't happened yet, and if it does it will be
the ONLY legal source of pergolide and your costs will more than
likely go up. Second option is to have your veterinarian petition the
FDA for an urgent need exemption for use of pergolide in your horse:

Since compounding from bulk is the only available option at the
moment, they would have to grant that permission but so far are
offering it only on a case by case basis. Considering the thousands
of horses that are probably on it, there's a chance that if we get
the ball rolling with these petitions they will quickly see the size
of the need and publish an exemption that allows bulk compounding of
pergolide for horses. This is a link to the process of getting an
exemption for an individual horse:

Urge your vets to do this.

Third thing is that I have sent a letter and background information
to every state's Board of Pharmacy. The FDA Compliance Guidelines
reference two court decisions that upheld the illegality of
compounding from bulk drugs. However, a recent Federal Court decision
in Texas found that it was legal. We can't wait for the courts to
hash it out, but the differences of opinion do leave the door open
for any individual state to make an exception. Susie Gordon found a
roster of state pharmacy boards yesterday. All the e-mails work. I
just put it up as a .pdf file. Anyone with a horse that needs
pergolide should contact your state board and let them know. Ask your
vets to do the same. If we keep the pressure on, there should be some
resolution of this before supplies disappear.

We need to keep the petition Kellie put up rolling too. It's the
documentation of need. Kellie is adding the FDA Ombudsman and all the
state pharmacy boards to her list of people that get copies of the
signatures every few days. Contact your local horse groups, 4-H
clubs, breed organizations - anyone you can think of. Send them to
the library to sign if you have to, but keep the signatures coming.

We can do this!

OK, below is a mail I put up on a vets' list this morning. It has the
exchange with the FDA in it, and what I wrote on that list.


Below is a copy of the first stages of an exchange with the FDA
regarding pergolide. It is important to remember that the pergolide
compounded from bulk drug that most are using is actually an illegal
product. The FDA does not have the manpower to police every
compounding pharmacy, but they can keep track of what goes into and
out of a handful of wholesale supply houses. Now that there is no
longer any legal market for the drug, the supply will dry up.

The first option the FDA suggested was to convince manufacturers of
the pills to resume production. So far, they're not interested in
doing that. Maybe with FDA intervention they will. However, in that
case the only option will be the manufactured pills, likely to
considerably increase the cost to owners.

Their second suggestion was for individual veterinarians to petition
for a medically necessary veterinary drug exemption which, if I am
understanding her correctly, would need to be done on a case by case
basis. This could be an agonizingly slow and laborious process but
if it comes to that I wanted all of you to know there may be hoops to
jump through before you can get pergolide to your clients. Since
there aren't any other options, you could be granted permission to
use bulk compounded pergolide - assuming your compounder could get

I'm hoping that the sheer magnitude of the need will lead to the FDA
publishing a specific exemption for compounding of pergolide from
bulk sources for use in horses with PPID, although that's probably
the last thing they want to do.

Letters and background information have also been sent to each
state's board of pharmacy, to hopefully open the door for exemptions
on a state by state basis. The 1994 AMDUCA legislation permitting
compounding did not specifically mention compounding from bulk drug
one way or the other. The compliance guidelines are FDA policy
statements, not law. They reference two court decisions that upheld
the ban on compounding from bulk drug, but a recent decision in a
Texas federal court ruled that veterinary compounding from bulk drug
was not illegal.

Thank you for your reply.

To date, none of the previous manufacturers of pergolide mesylate
tablets has expressed an interest in continued production of the drug
for veterinary use. One of the reasons for the petition at

which currently has almost 1400 signatures from both owners and
veterinarians, was to document that there is, indeed, a sizeable
market and need. We are periodically sending the previous
manufacturers spread sheet copies of the signatures. That option has
not opened up to us so far, but we will keep trying.

As for your second option, I will notify owners and veterinarians of

How long does the case review process take? That is, if veterinarians
were to wait until they actually had no other options, how long could
they expect to be without medication until a solution is achieved?

In the event manufacturers continue to express no interest in
resuming production, there would be no legal options available
according to Sec 608.400, CPG 7125.40 which specifically prohibits
compounding from bulk drug substances. Am I correct in assuming that
if the pharmaceutical industry continues to have no interest that
permission to use pergolide compounded from bulk drug may be granted
on a case by case basis, or does "case by case" actually mean for a
particular drug rather than each individual animal? Is there a way
the veterinary community at large could help expedite this process
for all horses with the need, rather than on an individual basis?
Would publishing a specific exemption for compounding of pergolide
from bulk drug for use in horses with PPID/Cushing's disease be a
viable option?

Use of pergolide in horses, a nonfood animal, poses no threat to
human health, and is of no environmental concern. We feel the
petition, which represents only a fraction of the horses impacted,
establishes the need and with voluntary withdrawal of the drug by
prior manufacturers we have a de facto loss of availability and no
approved avenues for obtaining it. Please advise whether individual
veterinarians/practices should begin the MNVP process for their
patients, or if there is a way this can be resolved on a larger scale.

Subject: Urgent Matter

Dear Dr. Larkins,
I apologize in advance if your office is not the proper place for
this issue, but since it involves the FDA proper and CVM on several
levels I am not sure where to turn. Please see the attached file. In
brief, the voluntary withdrawal of pergolide mesylate from the human
market is poised to have a disastrous impact on the health, even
survival, of many horses with pituitary dysfunction (pituitar pars
intermedia dysfunction, aka Equine Cushing's Diease). Owners of
horses that were relying on Permax or the generic tablets are already
having difficulty sourcing the drug from remaining supplies on the
market. Wholesalers supplying veterinary compounding pharmacies have
either decided to no longer stock it or are concerned/confused about
We are in desperate need of a clarification.

Thank you.

Update April 10, 2007

Posted on EC List 4/10/2007 Msg #90005

In speaking with some upper level management at drug wholesalers
yesterday, they came up with a variety of reasons for not stocking,
or considering not stocking, pergolide. Some of them were flat out
incorrect. Most, however, centered over concern about what the FDA
would do. They are saying they wouldn't be surprised if a prohibition
was put on the importation of pergolide (not there yet), and also
concerned for their own liability if they sell pergolide in bulk to a
compounding pharmacy (although obviously they've been doing this for
years). Problem is the FDA has been increasingly vigilant about
asking the wholesalers to identify where the drugs are going. With
the human market shut down, it would be obvious it's going to
veterinary compounders. Problem is, according to a Compliance
Guideline Document (this is *not* a law, it's a statement of action
the FDA might be inclined to take under a given set of
circumstances), compounding of veterinary prescriptions from bulk
drugs is a violation.

Here's where it gets sticky. A federal court decision in a Texas
district found that compounding of veterinary prescriptions from bulk
drug was not illegal. The official law on compounding of drugs for
nonfood animals, the 1994 AMDUCA (Animal Medicinal Drug Use
Clarification Act) permits compounding of drugs within the framework
of a valid veterinarian-client-patient relationship, i.e. your horse
is sick, your vet prescribes something for you, his/her client, to
give. AMDUCA doesn't mention compounding from bulk drug ingredients.

So, bottom line is that while we have to keep informing drug
wholesalers and generic pill manufacturers of the size of the market,
we also need to make the FDA very much aware of the need. Wholesalers
that fear prosecution are not going to stock this drug. That's why we
have moved the FDA to the top of the contact list on the petition.

Kellie is going to send copies of the petition response to everyone
on the petition list every few days. Wouldn't hurt one bit for anyone
who is so inclined to also send a personal e-mail to the FDA, or a
fax. The information is on the petition. Regulation of equine issues
really isn't usually very high on the FDAs list of priorities and in
issues like this they are usually very responsive to public feedback.
A good example of this is the threat to pull supplements like
glucosamine off the market a few years back.

I haven't gotten any feedback from the FDA yet. Will let everyone
know as soon as I do. In the meantime, keep the pressure on. E-MAIL


Update April 9, 2007 (Includes letter to Wholesalers)

Posted to EC List 4/9/2007 Msg #89950

I'm already starting to get mails from people using the human generics
and Permax saying that their pharmacies are out. All three pill
producers have stopped manufacturing. It appears that the only way the
pills will be produced again is if one of the 3 manufacturers appeals
to the USDA for a special permit. If that happens, that single
manufacturer will be the only source of pill form pergolide. Anyone
currently using pills would be wise to switch to compounded.

*The most accurate way to dose compounded pergolide is in capsule form.
In addition, anyone making a switch to a compounder should make sure

1. The compounder is fully licensed.
2. The compounder only uses bulk drugs that come from FDA approved drug
wholesalers. Ask for the name of their pergolide bulk drug wholesaler.
If it's not on the list below, don't use that compounder.

The petition is going strong, creeping up on 700 signatures
representing thousands of horses. In addition to signing the petition,
I would encourage anyone who feels so inclined to contact the
wholesalers directly by phone, fax or e-mail. When you do, be sure to
mention the name of your compounding pharmacy. One or more of the
wholesalers will recognize them as their clients and will be able to
check their sales records. As soon as a wholesaler confirms they will
continue to stock pergolide and keep the supply uninterrupted, we'll
take them off our contacts list. Also provide a link to the petition
when you contact them. This will be the quickest way to let them know
we have a need - a BIG need! Remember, the drug is out there. The human
market in the USA was very small compared to the rest of the world.

This is what I sent the wholesalers over the weekend and this morning.
Directly below that is a list of the FDA approved wholesalers who were
stocking pergolide and all the contact info I currently have.

Make your voice heard!

I am a veterinarian and co-owner of the over 5000 member Yahoo Equine
Cushing's group. As you know, at the FDA's urging pergolide mesylate
has been removed from the human market. The three US suppliers of
pergolide tablets are no longer producing the drug. What you may not
realize is that bulk sales of pergolide to compounders are largely
going to the veterinary market.

Pergolide is the only effective pharmacological therapy for horses with
Cushing's Disease, pituitary pars intermedia dysfunction. I believe
that drug wholesalers are unaware of the size of the veterinary market.
It is critically important to keep pergolide available for veterinary
use. The FDA action does not impact off-label use in horses.

A web petition has been put up to collect signatures and comments
regarding the use of pergolide in horses:

The petition was put up noon on April 6. Despite the holiday weekend,
there are already 14 pages of signatures, reflecting the needs of
thousands of horses. This is only the tip of the iceberg. There are
currently 10 to 12 million horses in the United States, of which
approximately 10% are age 20 or older. It has been estimated that
virtually any equine that lives long enough will develop the
degenerative changes of dopaminergic neurons that leads to pituitary
dysfunction and Cushing's disease. This disease may begin much earlier
in some horses, in their teens. Pergolide is needed by these animals
for the remainder of their life.

We urge you to continue to stock pergolide mesylate. There is a market.
Owners that had been relying on Permax or generic human tablets are
already encountering shortages. There is an urgent need to keep an
uninterrupted flow of pergolide mesylate to compounders.

Re: FDA Pergolide Withdrawal

If the continued availability of pergolide is not ensured, many horses with Cushing's disease (Pituitary Pars Intermedia Dysfunction or PPID) will be at risk to suffer the debilitating side effects of this disease. Cushing's is a "senior" disease - many with younger fit horses might not consider this important right now but any seasoned campaigner can be affected. Pergolide (obtained by veterinary prescription through compounding pharmacies or branded Permax which is no longer manufactured) is currently the only viable (effective and economical) treatment for this condition in horses. There currently are no alternatives.

For background:

Link to FDA notice

Link to article which summarizes the situation

Link to petition

This petition currently has over 3400 signatures, including many veterinarians. Eleanor Kellon, VMD, has spearheaded and is devoting countless hours to this effort in behalf of many thousands of Cushing's horses and their owners - contacting federal [FDA and CVM] and state officials, veterinary schools and organizations, writing articles, and working with pharmacists and research veterinarians in the U.S. and abroad.

This is a complex issue mired down in FDA rules and regulations beyond the scope of the average citizen or veterinarian.

Your attention and intervention into this current situation would be greatly appreciated by thousands of horse owners.

Claire's Letter to the FDA

Posted to EC Photos, reprinted with permission of author.

Dear Fellow Listers,

At Robin & Dr. Kellon's request I am posting a link to the letter I sent yesterday to Dr. Marcia Larkins and Dr. Stephen Sundlof at the FDA:

The reason I'm linking to it, rather than pasting it directly into this email is because it contains photos that I think are a very important and integral part of the message. And as you know we can't post photos directly into this list's messsages.
Read Claire's letter to the FDA.

Please understand that this letter is merely a SAMPLE of a personalized FDA plea. Please DO NOT copy my wording as it would really lessen the impact on those at FDA if they get letters that are very similarly worded -- BUT you can certainly use it as a starting point and modify it to fit your personal situation. The more letters they receive from horseowners talking about their specific horses, the more likely they are to view this as a very REAL threat to very REAL horses. Dr. Kellon has hit them with facts and numbers and hopefully educated them as to the value & importance of pergolide for treatment of these horses. You and I can make it real & personal. These are not just numbers, these horses are very real and part of our families.

Please write !! tell them your story...and specifically ask them to make a <<<"specific exemption from compounding from bulk drug for pergolide to be used to treat equine PPID">>>

If we lose just one horse due to the unavailability of pergolide's one too many !!!!! Jump on the band wagon and write to everyone who might have an impact.I have sent everyone in my address book the petition to sign and will continue to write letters until this issue is resolved.

At their request, I even wrote a story for a local AZ publication the "Bridle & Bit"...hope they can get in their next issue.We need to speak out ...loud & clear!!!!For my beloved Tamera and every horse out there that needs pergolide!!!!

Claire from AZ

[Claire's article in Bridle & Bit]

Time is Running Out

"There are an estimated 10 million or so horses in the United States, about 10% of which are in an age bracket that is classically high risk for Cushing's. If only 1% of those actually need and use pergolide, that's 10,000 horses that will likely have to be put down if (they don't have) medication," said Eleanor Kellon, VMD, co-owner of the Yahoo Equine Cushing's and Insulin Resistance Group. "The actual number is likely much higher. PPID is also being diagnosed much earlier now. It wouldn't surprise me if the actual number was closer to 50,000."
(quoted from The )

This could be my horse, your horse, the elite Olympic eventer or the school horse teaching kids to ride. No breed or type of horse is immune. This site has been started to keep you current on the latest information in the fight to keep pergolide available for our horses. There is at present no viable alternative to pergolide to control Cushing's Disease (PPID) or to stave off the debilitating, often painful and life-threatening side effects of this disease.

To begin - please sign the Save Pergolide petition, then encourage your friends and veterinarian to sign.

Then use the links to write to Federal and State officials, your elected representatives, equine veterinarian associations, your state horse councils and groups. If you can think of a link that should be added, let us know by adding a comment to this (or any) article.

Thank you.
