S(−)-Carbidopa is an inhibitor of peripheral decarboxylase, the enzyme responsible for conversion of L-DOPA to dopamine. Administration of S(−)-Carbidopa with L-DOPA demonstrates a decrease in the effects associated with rapid conversion of L-DOPA to dopamine. S(−)-Carbidopa is also demonstrated to prolong the elimination half-life of L-DOPA from blood plasma and skeletal muscle.
