- Aromatic L-amino acid decarboxylase inhibitor
-
An aromatic L-amino acid decarboxylase inhibitor (synonyms: DOPA decarboxylase inhibitor, DDCI and AAADI) is a drug which inhibits the synthesis of dopamine by the enzyme aromatic L-amino acid decarboxylase (AAAD, or DOPA decarboxylase, DDC).
Indications
Peripheral DDCIs incapable of crossing the protective blood-brain-barrier (BBB) are used in augmentation of L-DOPA (Levodopa) in the treatment of Parkinson's disease (PD) to block the peripheral conversion of L-DOPA into dopamine for the purpose of reducing adverse side effects.[1] Combined l-dopa and DDCI therapy does not inherently decrease peripheral cardiovascular side effects of l-dopa administration; however, combined therapy potentiates the central effects of l-dopa by decreasing the dose-dependency 4-5 fold, therein allowing for effective Parkinson's Disease treatment without cardiovascular risk associated with high peripheral dopamine.[2][3]
List of DDCIs
- Benserazide (Madopar, Prolopa, Modopar, Madopark, Neodopasol, EC-Doparyl, etc)
- Carbidopa (Lodosyn, Sinemet, Parcopa, Atamet, Stalevo, etc)
- Methyldopa (Aldomet, Aldoril, Dopamet, Dopegyt, etc)
