- Entacapone High Concentration(ENT-High) after 24hrs of incubation, refers to the drug concentration given to the six healthy adult individuals after twenty-four hours of incubation. Entacapone is a catechol-O-methyltransferase (COMT) inhibitor that acts by preventing the degradation of levodopa. It is the main drug used in the treatment of Parkinson’s disease. High concentration was based on estimated colon concentration and was included to better reflect the exposure of gut microbes to drugs in the large intestine.
