HOS-085591 · Präparat HOS-083163
An additive effect on QT interval prolongation between Fareston and the following drugs and other
medicinal products that may prolong the QTc interval cannot be excluded. This might lead to an
increased risk of ventricular arrhythmias, including Torsade de pointes. Therefore co-administration
of Fareston with any of the following medicinal products is contraindicated (see also section 4.3):
- antiarrhythmics class IA (e.g. quinidine, hydroquinidine, disopyramide)
- antiarrhythmics class III (e.g. amiodarone, sotalol, dofetilide, ibutilide)
- neuroleptics (e.g. phenothiazines, pimozide, sertindole, haloperidol, sultopride)
- certain antimicrobials agents (moxifloxacin, erythromycin IV, pentamidine, antimalarials
particularly halofantrine)
- certain antihistaminics (terfenadine, astemizole, mizolastine)
- others (cisapride, vincamine IV, bepridil, diphemanil).

Induction of CYP1A2
The metabolism of olanzapine may be induced by smoking and carbamazepine, which may lead to
reduced olanzapine concentrations. Only slight to moderate increase in olanzapine clearance has been
observed. The clinical consequences are likely to be limited, but clinical monitoring is recommended
and an increase of olanzapine dose may be considered if necessary (see section 4.2).

serum concentrations may be increased when co-administered with ritonavir

HOS-086558 · Präparat HOS-083306
Tasmar, as a COMT inhibitor, is known to increase the bioavailability of the co-administered levodopa.
The consequent increase in dopaminergic stimulation can lead to the dopaminergic adverse reactions
observed after treatment with COMT inhibitors. The most common of these are increased dyskinesia,
nausea, vomiting, abdominal pain, syncope, orthostatic complains, constipation, sleep disorders,
somnolence, hallucination.

Catechols and other drugs metabolised by catechol-O-methyltransferase (COMT)
Tolcapone may influence the pharmacokinetics of drugs metabolised by COMT. No effects were seen
on the pharmacokinetics of the COMT substrate carbidopa. An interaction was observed with
benserazide, which may lead to increased levels of benserazide and its active metabolite. The magnitude
of the effect was dependent on the dose of benserazide. The plasma concentrations of benserazide
observed after co-administration of tolcapone and benserazide-25 mg/levodopa were still within the
range of values observed with levodopa/benserazide alone. On the other hand, after coadministration of
tolcapone and benserazide-50 mg/levodopa the benserazide plasma concentrations could be increased
above the levels usually observed with levodopa/benserazide alone. The effect of tolcapone on the
pharmacokinetics of other drugs metabolised by COMT such as -methyldopa, dobutamine,
apomorphine, adrenaline and isoprenaline have not been evaluated. The prescriber should be observant
of adverse reactions caused by putative increased plasma levels of these drugs when combined with
Tasmar.

Potassium supplements and potassium-sparing diuretics: based on experience with the use of other
medicinal products that affect the renin-angiotensin system, concomitant use of potassium-sparing
diuretics, potassium supplements, salt substitutes containing potassium or other medicinal products
that may increase serum potassium levels (e.g. heparin) may lead to increases in serum potassium and
is, therefore, not recommended (see section 4.4).

As with ACE inhibitors, concomitant use of angiotensin II antagonists and NSAIDs may lead to an
increased risk of worsening of renal function, including possible acute renal failure, and an increase in
serum potassium, especially in patients with poor pre-existing renal function. The combination should
be administered with caution, especially in the elderly. Patients should be adequately hydrated and
consideration should be given to monitoring renal function after initiation of concomitant therapy, and
periodically thereafter.
