Docetaxel is highly protein bound (> 95%). Although the possible in vivo interaction of docetaxel
with concomitantly administered medicinal product has not been investigated formally, in vitro
interactions with tightly protein-bound agents such as erythromycin, diphenhydramine, propranolol,
propafenone, phenytoin, salicylate, sulfamethoxazole and sodium valproate did not affect protein
binding of docetaxel. In addition, dexamethasone did not affect protein binding of docetaxel.
Docetaxel did not influence the binding of digitoxin.

oxidation by CYP2C9 and glucuronidation and as a result is expected to decrease
the plasma concentrations of anticonvulsants. Careful monitoring of serum levels or

Rifampicin, a potent inducer of CYP3A4, but also CYP2C8, acts both as an inducer and inhibitor of
the metabolism of repaglinide. Seven days pre-treatment with rifampicin (600 mg), followed by co-
administration of repaglinide (a single dose of 4 mg) at day seven resulted in a 50% lower AUC
(effect of a combined induction and inhibition). When repaglinide was given 24 hours after the last
rifampicin dose, an 80% reduction of the repaglinide AUC was observed (effect of induction alone).
Concomitant use of rifampicin and repaglinide might therefore induce a need for repaglinide dose
adjustment which should be based on carefully monitored blood glucose concentrations at both
initiation of rifampicin treatment (acute inhibition), following dosing (mixed inhibition and
induction), withdrawal (induction alone) and up to approximately two weeks after withdrawal of
rifampicin where the inductive effect of rifampicin is no longer present. It cannot be excluded that
other inducers, e.g. phenytoin, carbamazepine, phenobarbital, St John’s wort, may have a similar
effect.

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
the potential to result in a serious interaction with sildenafil.
