Application

Entacapone has been used in high-performance bioaffinity chromatography.

Actions biochimiques/physiologiques

Entacapone acts predominantly in the intestine. It increases the bioavailability of levodopa. Levodopa is known to be associated with many complications such as motor fluctuations. COMT inhibitors have been used to overcome these adverse effects of levodopa by reducing its metabolism. Entacapone exhibits its inhibition action on COMT in the peripheral nervous system.
Entacapone is a catechol-O-methyl transferase (COMT) inhibitor. Used in treatment of Parkinson′s disease, entacapone is administered with L-DOPA to inihibit COMT from converting L-DOPA into a compound that cannot cross the blood brain barrier.

There is robust evidence that people with schizophrenia show elevated dopamine (DA) synthesis capacity in the striatum. This finding comes from positron emission tomography (PET) studies using radiolabelled l-3,4-dihydroxyphenylalanine (18F-DOPA). DA synthesis capacity also appears to be elevated in the

Positron emission tomography (PET) using the radiotracer [18F]-FDOPA provides a tool for studying brain dopamine synthesis capacity in animals and humans. We have previously standardised a micro-PET methodology in mice by intravenously administering [18F]-FDOPA via jugular vein cannulation and assessment

IPX066, an investigational extended-release carbidopa-levodopa (CD-LD) preparation, has demonstrated a rapid attainment and prolonged maintenance of therapeutic LD plasma concentrations in advanced Parkinson's disease (PD). This phase-3 crossover study assessed its efficacy and safety vs. CD-LD plus entacapone (CL + E). At
