This is a summary of the Public Assessment Report (PAR) for
Levodopa/Carbidopa/Entacapone film-coated tablets (PL 36687/0161-0166). It
explains how Levodopa/Carbidopa/Entacapone film-coated tablets were assessed and
their authorisation recommended, as well as the conditions of use. It is not intended to
provide practical advice on how to use these products.
For practical information about using Levodopa/Carbidopa/Entacapone film-coated
tablets, patients should read the package leaflet or contact their doctor or pharmacist.
What are Levodopa/Carbidopa/Entacapone film-coated tablets and what are
they used for?
These medicines are the same as Levodopa/Carbidopa/Entacapone Torrent Tablets
(PL 36687/0125-0130), authorised to the same Marketing Authorisation Holder
(Torrent Pharma (UK) Ltd).
Levodopa/Carbidopa/Entacapone film-coated tablets are used for the treatment of
Parkinson’s disease.
How do Levodopa/Carbidopa/Entacapone film-coated tablets work?
Parkinson’s disease is caused by low levels of a substance called dopamine in the
brain.
Levodopa/Carbidopa/Entacapone film-coated tablets contain three active substances
(levodopa, carbidopa and entacapone) in one film-coated tablet. Levodopa increases
the amount of dopamine and hence reduces the symptoms of Parkinson’s disease.
Carbidopa and entacapone improve the antiparkinson effects of levodopa.
How are Levodopa/Carbidopa/Entacapone film-coated tablets used?
Levodopa/Carbidopa/Entacapone film-coated tablets are taken by mouth.
Levodopa/Carbidopa/Entacapone film-coated tablets can only be obtained with a
prescription. The tablets should be taken exactly as told by the doctor or pharmacist.
The patient should check with the doctor or pharmacist if not sure.

I Introduction The Medicines and Healthcare products Regulatory Agency (MHRA) granted Torrent
Pharma (UK) Ltd, Marketing Authorisations for the medicinal products
Levodopa/Carbidopa/Entacapone 50 mg/12.5 mg/200 mg, 75 mg/18.75 mg/200 mg,
100 mg/25 mg/200 mg, 125 mg/31.25 mg /200 mg, 150 mg/37.5 mg/200 mg and 200
mg/50 mg/200 mg film-coated tablets (PL 36687/0161-0166) on 21 July 2016. These
products are prescription only medicines (POM) indicated for the treatment of adult
patients with Parkinson’s disease and end-of-dose motor fluctuations not stabilised on
levodopa/dopa decarboxylase (DDC) inhibitor treatment.
These applications were submitted as abridged simple applications, according to
Article 10c of Directive 2001/83/EC, as amended. The applicant has cross-referred to
Levodopa/Carbidopa/Entacapone Torrent Tablets (PL 36687/0125-0130), which were
first authorised to Torrent Pharma (UK) Ltd on 12 September 2014.
The active ingredients in these products are levodopa, carbidopa and entacapone.
Levodopa mediates the antiparkinsonian effect whereas carbidopa and entacapone
inhibit the peripheral metabolism of levodopa.
Levodopa is a precursor of dopamine and is given as replacement therapy in
Parkinson's disease.
Carbidopa is a peripheral DOPA-decarboxylase inhibitor. It prevents metabolism of
levodopa to dopamine in the peripheral circulation, ensuring that a higher proportion
of the dose reaches the brain, where dopamine acts. A lower dose of levodopa can be
used, reducing the incidence and severity of side effects.
Entacapone is a reversible, specific and mainly peripherally acting catechol-O-
methyltransferase (COMT) inhibitor. Entacapone decreases the metabolic loss of
levodopa to 3-O-methyldopa (3-OMD) mainly in peripheral tissues. The amount of
levodopa available to the brain is increased, thus prolongs the clinical response to
levodopa.
No new data were submitted nor were they necessary for these simple applications, as
the data are identical to those of the previously granted cross-reference products.
The MHRA has been assured that acceptable standards of Good Manufacturing
Practice (GMP) are in place for these product types at all sites responsible for the
manufacture and assembly of these products.
A Risk Management Plan (RMP) and a summary of the pharmacovigilance system
have been provided with these applications, and these are satisfactory.
