What is the difference between ergot and non ergot dopamine agonist?
They are known as ‘ergot’ types and include bromocriptine, pergolide and cabergoline. Because of this risk, these Parkinson’s drugs are no longer recommended and we haven’t included them here. Newer dopamine agonists are known as non-ergot. These are pramipexole, ropinirole, rotigotine and apomorphine.
