Effects of other substances on bexarotene
No formal studies to evaluate interactions with bexarotene have been conducted. On the basis of the
oxidative metabolism of bexarotene by cytochrome P450 3A4 (CYP3A4), coadministration with other
CYP3A4 substrates such as ketoconazole, itraconazole, protease inhibitors, clarithromycin and
erythromycin may theoretically lead to an increase in plasma bexarotene concentrations. Furthermore,
co-administration with CYP3A4 inducers such as rifampicin, phenytoin, dexamethasone or
phenobarbital may theoretically cause a reduction in plasma bexarotene concentrations.

The effect of ketoconazole, a prototype of potent and competitive inhibitors of CYP3A4, on the
pharmacokinetics of repaglinide has been studied in healthy subjects. Co-administration of 200 mg
ketoconazole increased the repaglinide (AUC and Cmax) by 1.2-fold with profiles of blood glucose
concentrations altered by less than 8% when administered concomitantly (a single dose of 4 mg
repaglinide). Co-administration of 100 mg itraconazole, an inhibitor of CYP3A4, has also been
studied in healthy volunteers, and increased the AUC by 1.4-fold. No significant effect on the glucose
level in healthy volunteers was observed. In an interaction study in healthy volunteers, co-
administration of 250 mg clarithromycin, a potent mechanism-based inhibitor of CYP3A4, slightly
increased the repaglinide (AUC) by 1.4-fold and Cmax by 1.7-fold and increased the mean incremental
AUC of serum insulin by 1.5-fold and the maximum concentration by 1.6-fold. The exact mechanism
of this interaction is not clear.

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.

Bosentan is metabolised by CYP2C9 and CYP3A4. Inhibition of these isoenzymes may increase the
plasma concentration of bosentan (see ketoconazole). The influence of CYP2C9 inhibitors on
bosentan concentration has not been studied. The combination should be used with caution.

Fluconazole and other inhibitors of both CYP2C9 and CYP3A4: Co-administration with fluconazole,
which inhibits mainly CYP2C9, but to some extent also CYP3A4, could lead to large increases in
plasma concentrations of bosentan. The combination is not recommended. For the same reason,
concomitant administration of both a potent CYP3A4 inhibitor (such as ketoconazole, itraconazole or
ritonavir) and a CYP2C9 inhibitor (such as voriconazole) with Tracleer is not recommended.

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)
