INDICATIONS AND USAGE
Carbidopa, levodopa and entacapone tablets, a combination drug consisting of levodopa (aromatic amino acid), carbidopa (aromatic amino acid decarboxylation inhibitor), and entacapone (catechol-O-methyltransferase (COMT) inhibitor) are indicated for the treatment of Parkinson's disease.
