Ok... All my medicine of Bromocriptine for Parkinson's disease says "Bromocriptine Mesylate Tablets contain bromocriptine mesylate (C32H40BrN5O5┬ĚCH4SO3) equivalent to 2.5mg Bromocriptine." I was told CAS numbers as well.

Bromocriptine mesylate (CAS 22260-51-1)
Bromocriptine (CAS 25614-03-3)

Suddenly I am expected to weigh the powder of BM instead of taking 10 pills at one time. I have no idea the equivelency! I am reading 90 to 110%.

I need 25mg dose of Bromocriptine. How much powder of the Mesylate do I measure out?

Thanks!

Looking at the formula the molecular weight is 750, 654 of which is bromocriptine and 96 is the mesylate, so your BM powder is 87.2% by mass bromocriptine. To get 25 mg of bromicriptine you therefore need 28.67 mg of BM powder.

Edit: damn just realised the thread is a year old! Will be more careful not to necro dead threads in future!

If the thread remains unanswered, don't forget that necro'ing it with a proper response may help a future user.
