Which statement is true about how drugs for Parkinson's disease work?
a. Dopaminergic drugs decrease the amount of dopamine activity in the brain.
b. COMT inhibitors allow a larger amount of levodopa to reach the brain, which lowers the brain's dopamine levels.
c. MAO-B inhibitors facilitate the enzyme monoamine oxidase B that breaks down dopamine in the brain.
d. Anticholinergic drugs block cholinergic nerve impulses to minimize tremors and rigidity.
D
Dopaminergic drugs increase the amount of dopamine activity in the brain. COMT (cate-chol-o-methyltransferase) inhibitors allow a larger amount of levodopa to reach the brain, which increases the brain's dopamine levels. MAO-B inhibitors inhibit the enzyme monoamine oxidase B that breaks down dopamine in the brain. Anticholinergic drugs are effective against tremors and rigidity by blocking cholinergic nerve impulses that help control the muscles of the arms, legs, and body.
