Target snapshot

Levodopa/Carbidopa (LD/CD) (Levodopa/Carbidopa (LD/CD)) — AbbVie. Levodopa is converted to dopamine in the brain to replace deficient neurotransmitter levels, while carbidopa inhibits premature conversion in the periphery, allowing more levodopa to reach the central nervous system.
