An
agonist is a class of drug that often
works by mimicking the action of a naturally occurring substance,
such as a neurotransmitter
in the brain. For example, patients
with Parkinson’s disease
experience the loss of brain cells that normally produce the
neurotransmitter dopamine. Such
patients are often treated by dopamine agonists, which mimic
the some of the effects of dopamine.
