Anovulatory Webinar

Additional Q&A

Q: Are there specific lights recommended for the artificial light? Wattage etc or the type of light doesn’t matter.

A: The light source must provide at least 200 foot candles of light. One should be able to read a news paper in the darkest area of the stall. Incandescent lights work well.

Q: Deslorelin, Histrelin and Buserelin are best ordered and available from the UK or USA?

A: Bet Pharm can provide you with Histrelin at both 50ug per ml (to stimulate follicular growth when given BID)and 0.5 mg/ml( for induction of ovulation).


EMS: My horse has Equine Metabolic Syndrome…what to do?

What is EMS?

Equine metabolic syndrome (EMS) can lead to a number of other issues with your horse including laminitis that can be traced back to insulin dysregulation (ID – or Insulin Resistance – IR). Also, as horses age they’re at an increased risk developing Pituitary Pars intermedia Dysfunction (PPID) which also may impact their weight and general health.

But WHY?

Similar to humans with type 2 diabetes, horses tend to exhibit many of the same symptoms when they have insulin resistance (e.g. obesity). Also like humans, there is likely a genetic link in some horses to gain and retain weight easier than others. These horses are often referred to as “easy keepers.”

Insulin is the hormone that allows the body’s cells to take in sugars from the blood. Genetically, some of us are predisposed to secrete more insulin than others when eating a meal (especially one made up of carbohydrates). Additionally, all of the cells that bind insulin (muscle and fat – for the purposes of this post) may also have reduced sensitivity to its effects. This creates a vicious cycle where the body is releasing more and more insulin (hyperinsulinemia – elevated levels of insulin in blood); which reduces the breakdown of FAT stores from the body (insulin inhibits lipolysis).

Does this mean that your horse is destined to be overweight eventually developing laminitis? Not necessarily.

Diagnosing whether your horse actually has EMS and insulin dysregulation if fairly simple. In a recently published article by Dr. Nicholas Frank, DVM, PhD, the diagnostic testing and criteria are outlined. The fasting Oral Sugar Test (OST – we love acronyms in medicine!) is the preferred method for stimulating insulin release because it allows practitioners to compare a horse’s insulin release with a known amount of sugar with the “normal” amount of insulin that SHOULD be released when the average horse is given the same quantity of sugar. The OST consists of giving 75 ml of Karo syrup orally per 1000 pounds body weight , collecting serum samples at 60 and 90 minutes and in some breeds such as Crillio at 120 minutes to assay Insulin concentrations.

Treatment options depend on the severity of the insulin dysregulation; which is why it’s important to perform OST before starting any kind of therapy. Cornell’s Animal Health Diagnostic Center has a nice synopsis of all of the currently recommended diagnostic tests for EMS; it can be found HERE.  To summarize:

  1. Assess insulin levels
  2. Oral Sugar Test
  3. Assess leptin levels (Which quantitates the extent of obesity)
  4. Assess Thyroid levels (T3, T4 & Free T4)

Dietary Management of EMS

The overall goal in EMS is to reduce the insulin levels in the body which can be achieved by reducing the amount of simple sugars in the diet. If any sweet feeds are being used, discontinue and replace with hay. There are numerous hypoglycemic concentrate rations are available on the market. Supplement any other energy requirements with some form of vegetable oil (1-2 cups/day). A grazing muzzle may also be necessary to limit the amount of grass and the associated fructans ,which are elevated by seasonal climatic changes, consumed.

Exercise is also warranted for treatment as it can reduce obesity and improve insulin sensitivity which results in a lowering of serum Insulin concentrations in as little as 4 days.  Moderate exercise  such as hand walking or swimming is highly recommended.

In severe cases of insulin dysregulation, a major concern is developing laminits; this is where medication therapy is indicated. Levothyroxine is a thyroid hormone that affects metabolism. A commercially available product by Lloyd is readily available in powder form. The starting dose is 0.1 mg/kilogram but it can also be administered at fairly high doses (48 mg of Levothyroxine Sodium – or 4 scoops) to quickly increase metabolic rate and fat stores.

Compounded flavored oral and MP injectable (once per month injection)  thyroxine can also be prescribed to reduce obesity. It usually takes 3 to 4 months of appropriate thyroxine therapy to achieve significant loss of body fat resulting in lowering of serum insulin. Several research studies have clearly shown that prolonged elevation of serum Insulin can cause laminitis. The target level of fasting serum insulin levels is 20 uU/ml .

Alternatively, a once a month Levothyroxine injection developed here at BET Pharm is available. It comes in a single dose vial and is injected just once every 30 days rather than daily oral administration. This has obvious benefits over a daily therapy but most of all lowers the chance for non-compliance. With an oral product, is the horse receiving the entire dose or is it falling to the bottom of the feed and being swept away? With a single dose given just once a month you can be sure that the horse is getting the entire dose and it is much less work.

Metformin has also been shown to improve insulin utilization however it’s poorly absorbed and can cause oral irritation (recommend rinsing mouth post administration to reduce irritation and prevent ulcers).


Next week we’ll be taking a closer look at PPID. We’ll discuss the signs and symptoms as well as diagnostic criteria and treatments.

FDA ALERT: Regumate, Matrix (altrenogest ORAL products) pose human health risk

As a compounding pharmacist and part time blogger, I’m subscribed to just about all of the FDA alerts related to drugs. The other day I received this email and it took me by surprise a little just because it mentions altrenogest, something I too compound with. As I read on though, none of the notification came as much of a shock. It relays the message that exposure to progestins (a form of progesterone, in this case: altrenogest is a synthetic progestin only approved for animal use – not human). The original FDA communication I received is below, including links to the FDA Alert.

Any female or male exposed to progestins can have adverse effects from that exposure. However, let’s keep in mind that more specifically, as the FDA notes here, is that this can especially be a problematic in teenage girls (their reproductive system). When you stop to think about it, Altrenogest is no different necessarily than any progestin-only birth control on the market, but remember this is for a HORSE (much larger than your average female teenager).

Many of these FDA approved products are made specifically to be readily and quickly absorbed through mucous membranes; skin exposure can mean a major disruption to a human female’s reproductive system. If proper precautions aren’t taken (i.e. wearing chemical resistant gloves, face shield and apron) this could mean detrimental health effects for anyone exposed. Whether administering to the horse directly, in their feed or even cleaning a stall that had Regumate sprayed on the feed; you must properly protect yourself or employees from exposure.

BETs two Altrenogest formulations: BioRelease Altrenogest 150 mg/mL and BioRelease Altrenogest 500 mg Microparticle are INJECTABLE forms of Altrenogest. Each are unique in their delivery system because of their long acting formulation (links to published research of these formulations below). Altrenogest 150 mg/mL is typically administered once every 2 weeks and our Microparticle formulation is given just ONCE a MONTH. Aside from the convenience, if theres a cost involved for administering the oral products daily this would also certainly cut labor costs as well.

Veterinarians typically use the Altrenogest 150 mg/mL as a progestin supplement for pregnancy maintenance while the Microparticle formulation is given once a month for estrus suppression. Aside from the cost difference, the once a month formulation (which is more expensive) also has a very low incidence of injection site reactions; which makes it ideal for use in horses DURING the race/show season.

In terms of safety, BOTH of our injectable formulations present the user with a much lower risk of exposure given the use of syringes and needles to administer the dose. There’s virtually no clean up (properly dispose of sharps in biohazardous waste) after it’s administered and a lower risk of our formulation being sprayed or splashed onto the human giving the injection.

FDA communication Received July 3, 2018:

FDA Animal Drug Safety Communication: FDA highlights potential health risks to people exposed to altrenogest products for horses or pigs

The U.S. Food and Drug Administration is alerting veterinary medical professionals, as well as those who work with horses and pigs, that a synthetic progesterone product commonly used in these animals may cause reproductive system disorders and other adverse effects in people who become exposed to the drug. The FDA is providing this alert because of the nature of the adverse events, some of which have occurred in teenage girls.

Altrenogest belongs to the class of drugs called progestins and is used to suppress estrus (commonly called “heat” or “season”) in mares (female horses), and to synchronize estrus in gilts (young female pigs). It is marketed under several brand names, including the equine products Regumate, Ovamed and Altren; and the swine products Matrix, Chronomate and Swinemate. The equine products are available via a veterinarian’s prescription and can be administered directly on the base of the mare’s tongue or on the mare’s feed. The swine products are available over-the-counter and are administered on a portion of the gilt’s feed. These liquid products may be administered to the animals on a daily basis for prolonged periods of time.

The agency has received 130 reports of accidental human exposure to altrenogest products between October 6, 1987 and May 30, 2018; 121 of those were for Regumate, approved in 1983, and nine reports were for Matrix, approved in 2003. Although the FDA has not received any reports for the other (generic) products, the agency’s alert includes these products because they are used in the same manner as Regumate and Matrix and on the same animal populations, and therefore have the same risk for adverse events.

Once a week* ULCER ALTERNATIVE – BioRelease Omeprazole

RE-release of BioRelease Omeprazole, an ulcer alternative

This last quarter we started compounding our BioRelease Injectable Omeprazole; a single dose injection that lasts one week.* We always felt that this was an excellent formulation but stopped making it for a couple years while attempting to do more research. We learned some valuable information and decided to release it again. Now that it’s been out for several months we called the veterinarians who’ve ordered and dispensed (some of them being repeat clients) to see what they had to say about the compound. Out of the 150+ doses that we’ve dispensed, only a handful of veterinarians were available for comment, but we were pleased with what they had to say…

Out of the 2 horses injected we’ve seen great improvement; honestly, did not scope either horse but we’re very pleased with your compound. We did switch needles like instructed and saw a very minimal site reaction – Dr. Liebsch.

This touches on one of the lessons learned when we performed some of our research.  In order to minimize site reactions we recommend that the needle be changed prior to injecting into the horse. That is generally best practice for injections so the patient is getting a new sterile needle rather than one that has also breached the vial. We also learned that the injection site needs to be rotated from week to week.

My client was very pleased. After 3 doses of your BioRelease Omeprazole the horse’s colic has cleared. – Dr. C. Buchanan

This wasn’t the only veterinarian that made this comment.  A few other vets had noticed that it had an effect after just 1-2 doses and colic symptoms had completely abated.

I really appreciated the small volume to be injected... – Dr. C. Guardia

This particular veterinarian had used another injectable omeprazole formulation that had a much larger injection volume and chose not to purchase again because of a site reaction from that compound. Our injection volume is only 6 mL when reconstituted.

I was very impressed and pleased; used BioRelease Omeprazole on 4 horses and all responded very quickly. – Dr. A. Roberts

Thanks Dr. Roberts!

Other Info about BioRelease Omeprazole

Omeprazole powder can quickly degrade when exposed to light and not held at refrigerated temperatures. BioRelease Omeprazole is shipped in two separate vials: one vial filled with BioRelease Omeprazole powder and the other BioRelease diluent. If you’ve used omeprazole in suspension form or another injection you may have noticed that it can turn purple (this is partly the reason it has always been branded using purple – including Prilosec capsules – which are purple!); this occurs when omeprazole is breaking down and it’s a sign of loss of stability of the formulation. Because we have it in two separate dark colored vials, our formulation keeps it’s stability so you know you’re getting the dose your horse needs.

Proton Pump Inhibitors (PPIs), Omeprazole’s drug class, are typically only indicated for short-term use in both humans and non-human animals. We recommend using our injectable formulation for a maximum duration of 4 weeks. If further therapy is indicated we recommend switching to an oral formulation for maintenance dosing.

Continuous Improvement

Here at BET we’re always trying to innovate and improve our formulations, processes…and our customer’s experience! Give us a call to try our BioRelease Omeprazole and of course we’d love to hear your feedback. Alternatively, you could also order using our ONLINE PHARMACY!

The BET difference: BioRelease Cabergoline improves PPID in retired horse

An email…

Every so often we receive emails letting us know how much someone likes our 30 day Altrenogest Microparticle compound for keeping their mare out of heat and what a difference they’re seeing in the horse. This most recent email though, we just had to share. One of our newest formulations is used in horses with PPID, BioRelease Cabergoline. It’s an injection that is given once every 2 weeks rather than a daily orally administered regimen. We were aleady aware of the difference a dopamine agonist can have on the symptoms associated with PPID but this particular case stuck out because of the drastic transformation presented.

I’ll let the email and pictures speak for themselves from here on out:



We started using the Cabergoline on my Danish warmblood Rowin in December. Rowin was imported from Europe. I also have another warmblood, a 22 year old Hanoverian cross, AJ. He was born and bred in Illinois. He’s been retired for a dozen years (lives outside 24/7) due to lameness issues. I was going to put him down this spring. (the pictures below are of AJ from April 20, 2018 – Before Cabergoline administration)












When my other horse, Row, was no longer responding to his therapy at the time, I switched him to Cabergoline. I gave them to AJ. Not much happened. Couldn’t bring myself to put him down. Rowin then had a stroke right before Easter so I decided to give AJ the shot too since I wasn’t sure what was going to happen with Row.

Attached are pictures from April this year and last year and then 3 weeks ago after 6 – 3/4cc injections. AJ has had no feed, supplements etc.. just grass and hay in the winter since he lives outside. I didn’t bathe him, work him; nothing other than the shedding blade. I haven’t sat on him in a couple years.  Since he’s been turned I used to sit on him a couple times a year but haven’t the last 2 years because he looked so poorly. I think these pictures speak volumes!! He looks amazing and other than the shot he has had nothing but pasture or hay. (the pictures below are of AJ from June 14, 2018 – AFTER Cabergoline administration)




I can’t thank you enough!!

– K.E.
