Description

General description

Carbidopa is used for treating restless legs (RL) syndrome and periodic leg movements in sleep (PLMS). Carbidopa along with levodopa is used to treat Parkinson′s disease.

Biochem/physiol Actions

Peripheral inhibitor of L-aromatic amino acid decarboxylase. When co-administered with L-DOPA, it prevents extra-CNS conversion to dopamine, thereby increasing CNS concentrations of effective compounds. Selectively cytotoxic to human pulmonary carcinoid and small cell lung carcinoma cells by increasing H₂O₂ in these cell lines, which are sensitive to reactive oxygen species.

Peripheral inhibitor of L-aromatic amino acid decarboxylase.
