Okay, I think I understand what your saying Wilson. It basically comes down to the word compounded. I will make sure that I refer to it as bulk, powdered Itra from now on. I know that a lot of dogs are lost on the brand name too. Some are just too sick to respond to anything.
Like I said, I think its a personal decision, but in order to make an informed decision you have to understand all the facts.
If there was no affordable alternative, I would encourage the use of bulk, powdered Itra. But there are alternatives. You just never really know what your getting, the extent it is already degraded or the extent for which bulk, powdered Itra it is being absorbed. My understanding is that the FDA only approved compounders to make up capsules of bulk, powdered Itra for veternarian use to treat mange. While mange is uncomfortable, its not usually deadly like Blasto. Compounders don't test the effectiveness of the bulk, powdered Itra before distributing it capsules and the bulk, powdered form. It is primarily distributed to be used in manufacturing of Spornax, generics and suspensions. During this process it is all used at one time and degregation is minimized. Everytime the jug of bulk is opened and exposed to light, air, glass it is degraded. The bulk that is touching the sides of the jug has been degraded. I just wonder how many times a compounder is opening up a jug of bulk, powdered Itra and taking out enough to make 30- 125mg capsules. If you think about it, that is not very much product. How long is the product sitting on the compounders shelves? I seriously doubt that the compounder is throwing away a half used jug of bulk powder Itra just because it has degraded. If its not expired or yellowed, or bad, they are going to continue making it into caps regardless of how effective it may or may not be.
Its a crap shoot as to what your are getting. And the reasearch shows that dogs who were successfully treated with the bulk, powdered Itra had a greater chance of relapse. In consideration of the research done and my personal experience with it, I could not recommend it in clear conscious.
When Lola got her Mira Vista report after being on the bulk, powdered Itra for 3 months, her numbers were still off the charts. The Itra Lola was taking was ALWAYS took with lots of fats, her entire diet revolved around fats at that point. It was kept in sealed, opaque bottles and used correctly. Confused as to how she could appear to be doing so well and still have numbers off the chart, I phoned Mira Vista and talked to them personally. I talked to them about running the test to check for absorbtion (to see if enough Itra was being absorbed). They asked me if I was using bulk, powdered and I told them yes. And they told me to save my money, the test was pricey and they could already tell me that enough wasn't being absorbed. They told me that they have had very, very few absorbtion tests come back good when bulk, powdered Itra was used. Lola didn't get her first positive until we completed the first 18 days on Spronax. They explained that they had changed the way they produced their numbers between Lolas first test and this second test after she had been on the powdered Itra for 3 months. But in correlating the two, their was very little, if any change and that they would expect to see a minimum of 1-2 point decrease per month if the levels were adaquate.
Im not sure if the Mira Vista test is perfect either, but its the most perfect that we have and I know that you didn't discontinue Wilsons meds until he had a negative Mira Vista test. So you must have had some faith in the test.

However, during compounding, inactivation may occur. Itraconazole is insoluble in water and cannot be formulated into aqueous vehicles. Itraconazole may also adsorb to plastic and glassware, decreasing product drug concentrations. Recently in our laboratory, a clinician requested an assay of a 100-mg capsule of itraconazole that was formulated by a compounding pharmacist. We found that the concentrations of itraconazole or the metabolite hydroxyitraconazole were undetectable from the compounded capsule.
