What effect would a drug that inhibits dopamine β-hydroxylase likely have if combined with cocaine?

Question

Quizplus · Accepted Answer

Dopamine β-hydroxylase is an enzyme that converts dopamine into norepinephrine. Inhibiting this enzyme would lead to increased dopamine levels because its conversion to norepinephrine is blocked. Cocaine increases the amount of dopamine by blocking its reuptake, so inhibiting dopamine β-hydroxylase would exacerbate the effects associated with elevated dopamine levels, such as paranoia.
