En klinisk undersøgelse hos levertransplanterede patienter har vist, at der ikke forekommer nogen farmakokinetisk interaktion, når adefovirdipivoxil 10 mg én gang daglig indgives samtidig med tacrolimus, som er et immunsuppressivt middel, der hovedsagelig metaboliseres via CYP450- systemet.
A clinical study in liver-transplant patients has shown that no pharmacokinetic interaction occurs when adefovir dipivoxil 10 mg once daily is administered concomitantly with tacrolimus, an immunosuppressant which is predominantly metabolised via the CYP450 system.
