Carbidopa-d3 is intended for use as an internal standard for the quantification of carbidopa (Item No. 23783) by GC- or LC-MS. Carbidopa is a peripherally restricted inhibitor of dopamine decarboxylase, the enzyme that converts L-DOPA (Item No. 13248) to dopamine.{41269} Administration of carbidopa (100 mg/kg) prior to administration of L-DOPA in dogs increases the plasma concentration of L-DOPA by 186% and prolongs the half-life in plasma by 48% and skeletal muscle extracellular fluid by 66%.{41270} Carbidopa also binds to and potentiates the activity of the aryl hydrocarbon receptor (AhR).{41271} It inhibits the proliferation of pancreatic cancer cells in vitro and tumor growth in vivo. Formulations containing carbidopa are used in combination with L-DOPA in the treatment of Parkinson’s disease to increase the amount of dopamine in the brain and reduce peripheral side effects associated with L-DOPA administration.
