In case of combination with CYP3A4 inhibitors, the occurrence of docetaxel adverse reactions may
increase, as a result of reduced metabolism. If the concomitant use of a strong CYP3A4 inhibitor (e.g.,
ketoconazole, itraconazole, clarithromycin, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir,
telithromycin and voriconazole) cannot be avoided, a close clinical surveillance is warranted and a
dose-adjustment of docetaxel may be suitable during the treatment with the strong CYP3A4 inhibitor
(see section 4.4). In a pharmacokinetic study with 7 patients, the co-administration of docetaxel with
the strong CYP3A4 inhibitor ketoconazole leads to a significant decrease in docetaxel clearance by
49%.

Theoretically the metabolism of toremifene is inhibited by drugs known to inhibit the CYP3A enzyme
system which is reported to be responsible for its main metabolic pathways. Examples of such drugs
are antifungal imidazoles (ketoconazole); other antifungal agents (itraconazole, voriconazole,
posaconazole); protease inhibitors (ritonavir, nelfinavir), macrolides (clarithromycin, erythromycin,
telithromycine). Concomitant use of those drugs with toremifene should be carefully considered.

Due to the large therapeutic window of clarithromycin no dose reduction should be
necessary in patients with normal renal function. Clarithromycin doses greater than
1 g per day should not be co-administered with ritonavir dosed as an antiretroviral
agent or as a pharmacokinetic enhancer. For patients with renal impairment, a
clarithromycin dose reduction should be considered: for patients with creatinine
clearance of 30 to 60 ml/min the dose should be reduced by 50%, for patients with
creatinine clearance less than 30 ml/min the dose should be reduced by 75%.

Substances that inhibit the cytochrome P450 isoenzyme CYP3A4 activity (e.g. protease inhibitors
such as indinavir, lopinavir/ritonavir, ritonavir, saquinavir, telaprevir, nelfinavir, boceprevir; azole
antifungals including ketoconazole, itraconazole, posaconazole, voriconazole; certain macrolides such
as erythromycin, clarithromycin and telithromycin) could decrease metabolism and increase imatinib
concentrations. There was a significant increase in exposure to imatinib (the mean Cmax and AUC of
imatinib rose by 26% and 40%, respectively) in healthy subjects when it was co-administered with a
single dose of ketoconazole (a CYP3A4 inhibitor). Caution should be taken when administering
Glivec with inhibitors of the CYP3A4 family.

Cytochrome P450 inhibitors
Tadalafil is principally metabolised by CYP3A4. A selective inhibitor of CYP3A4, ketoconazole
(200 mg daily), increased tadalafil (10 mg) exposure (AUC) 2-fold and Cmax by 15 %, relative to the
AUC and Cmax values for tadalafil alone. Ketoconazole (400 mg daily) increased tadalafil (20 mg)
exposure (AUC) 4-fold and Cmax by 22 %. Ritonavir, a protease inhibitor (200 mg twice daily), which
is an inhibitor of CYP3A4, CYP2C9, CYP2C19, and CYP2D6, increased tadalafil (20 mg)
exposure (AUC) 2-fold with no change in Cmax. Although specific interactions have not been studied,
other protease inhibitors, such as saquinavir, and other CYP3A4 inhibitors, such as erythromycin,
clarithromycin, itraconazole and grapefruit juice should be co-administered with caution as they would
be expected to increase plasma concentrations of tadalafil (see section 4.4).
Consequently the incidence of the adverse reactions listed in section 4.8 might be increased.
