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.

The cytochrome P-450 isozymes responsible for metabolism of brinzolamide include CYP3A4 (main),
CYP2A6, CYP2C8 and CYP2C9. It is expected that inhibitors of CYP3A4 such as ketoconazole,
itraconazole, clotrimazole, ritonavir and troleandomycin will inhibit the metabolism of brinzolamide
by CYP3A4. Caution is advised if CYP3A4 inhibitors are given concomitantly. However,
accumulation of brinzolamide is unlikely as renal elimination is the major route. Brinzolamide is not
an inhibitor of cytochrome P-450 isozymes.

Ketoconazole: Co-administration for 6 days of bosentan 62.5 mg twice daily with ketoconazole, a
potent CYP3A4 inhibitor, increased the plasma concentrations of bosentan approximately 2-fold. No
dose adjustment of Tracleer is considered necessary. Although not demonstrated through in vivo
studies, similar increases in bosentan plasma concentrations are expected with the other potent
CYP3A4 inhibitors (such as itraconazole or ritonavir). However, when combined with a CYP3A4
inhibitor, patients who are poor metabolisers of CYP2C9 are at risk of increases in bosentan plasma
concentrations that may be of higher magnitude, thus leading to potential harmful adverse events.

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.
