benserazide

benserazide /ben-ser′ah-zīd/ , an inhibitor of the decarboxylation of peripheral levodopa to dopamine, having actions similar to those of carbidopa. When given with levodopa, benserazide produces higher brain concentrations of dopamine with lower doses of levodopa, thus lessening the side effects seen with higher doses. It is used orally in conjunction with levodopa as an antiparkinsonian agent.
