Biochem/physiol Actions

Peripheral inhibitor of L-aromatic amino acid decarboxylase.

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.
