Yen. Bromocriptine is an agonist. What that means is that it functions like dopamine on the receptor. Therefore it and/or other agonists can either substitute for or combine with sinemet (carbidopa-levodopa) to produce the effect of the reduced amount of dopamine in PD. Selegiline, also known as Eldepryl, blocks the breakdown of dopamine in the synapse therefore increasing the amount and duration of action of the dopamine in the synapse. It also is thought to slow the progression of the disease. I hope this is helpful, Check website http://www2.onu.edu/~ksehlhor/drugs.html for a better explanation of most of the PD drugs Also Yen, where do you live?
