Agroup of nursing students are preparing for a class presentation to discuss drugs used to treat parkinson disease. which drug would the group include when discussing dopaminergic agents?

The group could include the drug levodopa as well as the dopamine agonists. Levodopa is a precursor of dopamine.

The dopamine agonists work alike, binding directly to the dopamine receptors, mimetising its action.

All of them are man made
