Effect of tolcapone on the metabolism of other drugs
Due to its affinity for cytochrome CYP2C9 in vitro, tolcapone may interfere with drugs whose clearance
is dependent on this metabolic pathway, such as tolbutamide and warfarin. In an interaction study,
tolcapone did not change the pharmacokinetics of tolbutamide. Therefore, clinically relevant interactions
involving cytochrome CYP2C9 appear unlikely.

Although specific interaction studies were not conducted for all medicinal products, population
pharmacokinetic analysis showed no effect of concomitant treatment on sildenafil pharmacokinetics
when grouped as CYP2C9 inhibitors (such as tolbutamide, warfarin, phenytoin), CYP2D6 inhibitors
(such as selective serotonin reuptake inhibitors, tricyclic antidepressants), thiazide and related
diuretics, loop and potassium sparing diuretics, angiotensin converting enzyme inhibitors, calcium
channel blockers, beta-adrenoreceptor antagonists or inducers of CYP450 metabolism (such as
rifampicin, barbiturates). In a study of healthy male volunteers, co-administration of the endothelin
antagonist, bosentan, (an inducer of CYP3A4 [moderate], CYP2C9 and possibly of CYP2C19) at
steady state (125 mg twice a day) with sildenafil at steady state (80 mg three times a day) resulted in
62.6% and 55.4% decrease in sildenafil AUC and Cmax, respectively. Therefore, concomitant
administration of strong CYP3A4 inducers, such as rifampin, is expected to cause greater decreases in
plasma concentrations of sildenafil.

Nicorandil is a hybrid of potassium channel activator and nitrate. Due to the nitrate component it has

Administration of Pegasys 180 micrograms once weekly for 4 weeks in healthy male subjects did not
show any effect on mephenytoin, dapsone, debrisoquine and tolbutamide pharmacokinetics profiles,
suggesting that Pegasys has no effect on in vivo metabolic activity of cytochrome P450 3A4, 2C9,
2C19 and 2D6 isozymes.

Induction
As a mild inducer of CYP2C9, CYP3A4 and glucuronidation, aprepitant can decrease plasma
concentrations of substrates eliminated by these routes within two weeks following initiation and
treatment. This effect may become apparent only after the end of a 3-day treatment with EMEND. For
CYP2C9 and CYP3A4 substrates, the induction is transient with a maximum effect reached 3-5 days
after end of the EMEND 3-day treatment. The effect is maintained for a few days, thereafter slowly
declines and is clinically insignificant by two weeks after end of EMEND treatment. Mild induction of
glucuronidation is also seen with 80 mg oral aprepitant given for 7 days. Data are lacking regarding
effects on CYP2C8 and CYP2C19. Caution is advised when warfarin, acenocoumarol, tolbutamide,
phenytoin or other active substances that are known to be metabolised by CYP2C9 are administered
during this time period.

Tolbutamide
EMEND, when given as 125 mg on Day 1 and 80 mg/day on Days 2 and 3, decreased the AUC of
tolbutamide (a CYP2C9 substrate) by 23 % on Day 4, 28 % on Day 8, and 15 % on Day 15, when a
single dose of tolbutamide 500 mg was administered orally prior to the administration of the 3-day
regimen of EMEND and on Days 4, 8, and 15.

Based on data from a clinical interaction study with 80 mg nitisinone at steady-state, nitisinone is a
moderate inhibitor of CYP2C9 (2.3-fold increase in tolbutamide AUC), therefore nitisinone treatment
may result in increased plasma concentrations of co-administered medicinal products metabolized
primarily via CYP2C9 (see section 4.4).
Nitisinone is a weak inducer of CYP2E1 (30% decrease in chlorzoxazone AUC) and a weak inhibitor
of OAT1 and OAT3 (1.7-fold increase in AUC of furosemide), whereas nitisinone did not inhibit
CYP2D6 (see section 5.2).
