Hi Ian,

Here is the post from Dr. Kellon regarding the pergolide mesylate/Prascend "mystery".

This is the reply from BI:

Thank you for contacting Boehringer Ingelheim Veterinary Technical Services. You raised a very good question that, frankly, took a few days to circulate and find the answer.


The brief answer is, Prascend is the same worldwide. So, as you identified, the language is different from US & UK. No matter US or UK, there is 1.3 mg of pergolide mesylate (the salt) and once metabolized, 1 mg of pergolide.


So, to answer your question below, 1 tablet contains 1 mg of actual pergolide (1.3 mg of pergolide mesylate).


Let us know if you have further questions.


Best regards,
