CLINICAL PARTICULARS
4.1
THERAPEUTIC INDICATIONS
Entacapone is indicated as an adjunct to standard preparations of
levodopa/benserazide or
levodopa/carbidopa for use in adult patients with Parkinson’s
disease and end-of-dose motor
fluctuations, who cannot be stabilised on those combinations.
4.2
POSOLOGY AND METHOD OF ADMINISTRATION
Entacapone should only be used in combination with
levodopa/benserazide or levodopa/carbidopa.
The prescribing information for these levodopa preparations is
applicable to their concomitant use
with entacapone.
Posology
One 200 mg tablet is taken with each levodopa/dopa decarboxylase
inhibitor dose. The maximum
recommended dose is 200 mg ten times daily, i.e. 2,000 mg of
entacapone.
Entacapone enhances the effects of levodopa. Hence, to reduce
levodopa-related dopaminergic
adverse reactions, e.g. dyskinesias, nausea, vomiting and
hallucinations, it is often necessary to
adjust levodopa dosage within the first days to first weeks after
initiating entacapone treatment. The
daily dose of levodopa should be reduced by about 10–30% by
extending the dosing intervals and/or
by reducing the amount of levodopa per dose, according to the clinical
condition of the patient.
If entacapone treatment is discontinued, it is necessary to adjust the
dosing of other antiparkinsonian
treatments, especially levodopa, to achieve a sufficient level of
control of the parkinsonian
symptoms.
Entacapone increases the bioavailability of levodopa from standard
levodopa/benserazide
preparations slightly
