What is dopamine as a medication?

Dopamine is an important neurotransmitter that plays a key role in the central nervous system. Dopaminergic drugs primarily include dopamine receptor agonists, which directly stimulate dopamine receptor sites and thereby influence physiological processes. These drugs are divided into two main categories: ergot-derived and non-ergot-derived agents. Ergot derivatives include cabergoline and bromocriptine, while non-ergot derivatives include piribedil and pramipexole. Dopaminergic drugs are mainly used to treat psychiatric disorders, increase blood pressure, and affect blood vessels and blood pressure regulation. These medications may also cause certain side effects, such as arrhythmias and generalized weakness or fatigue, and should be used under medical supervision.
