I might be misremembering, but AFAIK, dopamine can’t cross the blood-brain-barrier, so even where you want to regulate dopamine (and not, e.g. serotonin like more commonly for depression) in the brain, you have to do so via different medication (e.g. amphetamine derivatives for ADHD or dopamine agonists for Parkinson’s).
