Bromocriptine and Blood Brain Barrier

[Laurie Davison]

Actually, this was my concern and my reason for asking. I understand that 
dopamine itself cannot pass the blood-brain barrier, which is why L-dopa 
is used instead in Parkinson's patients. It concerned me that 
bromocriptine may have a similar enough structure to dopamine that it 
would not pass the barrier. I appreciate your responses!
