Dopamine agonists have also been studied for their effects in treating parkinson’s symptoms unlike levodopa, dopamine agonists do not require modification from brain enzymes to stimulate dopamine receptors dopamine agonists like pramipexole and ropinirole may be used in place of levodopa during the early stages of parkinson’s.

Just under half of all the impulse control events were related to dopamine receptor agonists (710, 449%) and the remainder to other drugs the reports related to dopamine receptor agonists occurred in people with an average age of 55 years, and over half of whom were male.
Both antagonists and agonists act on the post-synaptic neuron antagonists and agonists will pretend to be serotonin and engage the 5-ht receptors the agonist will activate the receptor as serotonin would and the antagonist will not activate the receptor but will block serotonin from from acting on the receptor.
