What medications block dopamine?
Other examples of dopamine blockers and depletors include: chlorpromazine hydrochloride (Thorazine) domperidone droperidol (Inapsine) fluphenazine hydrochloride (Prolixin) metoclopramide (Reglan) perphenazine (Trilafon) prochlorperazine (Compazine) thiethylperazine (Torecan) trimethobenzamide (Tigan) reserpine (Serpalan)
What drugs raise dopamine levels?
There are several reasons for high levels of dopamine in the brain. Illegal or medicinal drugs can raise dopamine, such as the drug L-Dopa that is used to treat Parkinson’s disease. Cocaine and amphetamines elevate levels of dopamine, as does risk-taking. Both release dopamine in the brain, giving the person a "high.".

The data revealed an interaction such that openness to experience was more positively associated with divergent thinking in the dopamine blocker group (r=0.304) than in the placebo group (r=−0.002).

The prokinetic drug metoclopramide is a dopamine receptor blocker which should be avoided. Patients should be encouraged to take L-dopa on an empty stomach and avoid protein at the time of drug administration. DYSKINESIAS — Dyskinesias refer to a variety of involuntary movements which occur as a direct effect of L-dopa [18].

Control of the hypertension in these disorders can be achieved with phentolamine, labetalol, or nitroprusside. Ad- ministration of a ß-blocker alone is contraindicated, since inhibition of ß-receptor-induced vasodilation results in unop- posed alpha-adrenergic vasoconstriction and a further rise in BP.
