Box 4135 > Topeka, KS 66604 > 785-233-3185 ****************************** Not long ago, I read about this low cost lupron that was being sold in Kansas, and I chose to check it out. I had a ferret that was clearly showing sig ns of Adrenal disease, and I wanted to try the Lupron injection to buy me some time before surgery. I made it clear to this vet that I wanted a 3 month supply, as I had surgery scheduled after the 3rd month. I received a 3 month supply (3 pre measured doses, in a syringe with a needle) via next day air Fed Ex from Dr Larry Snyder. I gave Shal Dee his first dose of it in January 2004. Soon after the first dose was given, I questioned the expiration dates of the 2 remaining injections. I was told by the vet (Larry) that this lupron basically did not have an expiration date, and that it could be stored in the refrigerator. I gave Shal Dee his second dose in February, and saw no improvements. I then decided to research this, as I had never used lupron before. I contacted a few others to help, Mike Janke was one of the people I contacted. Come to find out, the lupron that I was using for my ferret was the 24 hour lupron, not the monthly lupron that the vet told me he was selling. I was given the wrong information, and very well could have harmed my ferret. In March, Shal Dee had his surgery, he was bilateral, and recovered well, he is doing fine now. The reason why I am posting this, is to hopefully open some eyes, and make sure that you check things out before you buy it. Personally I would not recommend using the Lupron that is being sold by Dr Larry Snyder. Here is a post Mike Janke had written, soon after he discovered what had happened to Shal Dee and I, and thank you Mike for researching this for me!

Several emails were exchanged and this led to my learning that a pharmacy and vet in the Midwest is selling 24 hr. Lupron across the U.S. with the claim that it is effective for approximately one month. I was surprised to hear this and didn't believe this to be true, but since I'm not a vet or medical expert, I told this person that I would do some research before making any claims. I tried to get a better explanation from the vet and pharmacist prescribing this Lupron, to no avail. In their defense, I did not speak to them directly but through a second party. The only thing I knew was the claim that it worked long term because of, "the way it attaches to the adrenal receptors." I was looking for a little more detailed explanation how this works for a period longer than 24 hours but never found out any more than that. I wrote to several vets I know and whose names would probably be familiar to many here and the response I got was that 24 hr. Lupron works for 24 hrs., period. That was appreciated but their response did not include any real explanation as to why it could not work as claimed. I then decided to contact John Hines, who wrote, "Adrenal Disease and the Therapeutic Effect of Lupron." Since John studied the topic of Lupron usage and has a Ph.D. in Pharmacology, I felt I wouldn't find anyone more knowledgeable on the subject and definitely one with the credentials to offer an expert opinion. First a brief layman's description (mine!) of how Lupron works so some of John's comments might make a little more sense. Lupron desensitizes the pituitary gland and causes it to stop producing two hormones, LH and FSH. These two hormones (the primary problem is LH I believe) stimulate the adrenal glands into producing sex hormones which cause the adrenal disease symptoms we see. This is an extremely basic explanation. There are many more details in John's paper and if you'd like to read his paper and get a little more scientific explanation, go to http://www.miamiferret.org/fhc/lupron.htm. The main question to John was, how can 24 hr. Lupron be effective in ferrets for adrenal disease treatment if used as a monthly dose? John's comments on the topic were as follows... [all quoted material posted with John's permission] "... if the Lupron is of the type that all enters the bloodstream in 24 hrs., (24 hr. Lupron) what you get is a few hours of high pituitary activity followed by only several HOURS of inactivity (desensitized). Then the 24 hr. Lupron is gone shortly thereafter, and the pituitary RE-sensitizes and LH release to the natural GnRH resumes probably in a day or so. If the ferret is only getting the 24hr. shot once a month, it's useless. In fact, the use of the 24 hr. Lupron probably makes the adrenal disease worse because you don't get much therapeutic effect, but you are still getting that initial high pituitary activity when the Lupron is first administered. This initial burst of pituitary activity is of little consequence when it is followed by cessation of pituitary activity. But, with the 24 hr. Lupron, you get only the initial burst of pituitary high activity -- followed by normal pituitary activity. It's like adding a splash of gasoline to a fire." We had several discussions, particularly about the claim that the 24 hr. Lupron works for a month or more because of "the way it attaches to the adrenal receptors" to which John responded... "I did notice in your earlier correspondence that the vet and pharmacist had described their Lupron as binding to 'adrenal receptors'. I can see how a drug that binds to the pituitary and impacts on the adrenals could be misconstrued as binding to the adrenals by the average person; however, if the pharmacist or vet actually said to her that "Lupron binds to adrenals", then that immediately is cause for concern as it demonstrates a fundamental ignorance about how the drug works." And... "[pharmacist's name omitted] doesn't understand how Lupron works. He seems to know what its ultimate effect is, just not the mechanism. That's a shame, because he should know better than anyone. Leuprolide binds to receptors on the pituitary. The word "attach" could be misleading -- to some people it might imply a permanent joining of the leuprolide to the GnRH receptor, which is not the case. Leuprolide tightly associates ("binds") with the GnRH receptor, but it is a reversible process. It can dissociate ("unbind") as well." I want to thank John for putting up with all my questions and taking time out of his busy days to share his knowledge on this topic. I know that this vet does a lot of good for ferrets and I understand the intent is to offer an affordable alternative for treatment of this all too common disease. Does this Lupron work in some cases? So I hear. What worries me, besides the fact that this type of Lupron may not work, is that after hearing John's explanation, realizing that there is also the chance it could make the condition worse. The other important message I want to get across is, ask questions, know what you are getting and what you're treating your ferret with. This applies to ANY treatment, not just one for adrenal disease. In this case, I was told by the person that contacted me that she was not told that what she was getting was 24 hr. Lupron, only that it would work for a month or so. I am fairly sure that if the vet had been asked directly, "Is this 24 hr. Lupron?" or "What formulation of Lupron is this?" the vet would have been honest and upfront. Vets (even human doctors) often don't give us all the information unless we specifically ask for it. So don't be afraid to ask. If this 24 hr. Lupron is something you want to try for whatever reason, this probably won't change your mind. Just be aware that you may see no results and in fact, may make matters worse. mike Kris and the Fur Kids >^..^ [Posted in FML issue 4553]
