Ans: The strategy could include anything that would diminish dopamine neurotransmission or specifically counteract amphetamine. For example, the drug could inhibit an enzyme used in dopamine synthesis or it could serve as an antagonist at dopamine receptors. The drug could also prevent amphetamine from binding to vesicular or membrane transporters.
