The possibility of interactions with other medicinal products administered concurrently should be
considered, particularly when the main route of elimination is active renal secretion via the organic
cationic transport system e.g. trimethoprim. Other medicinal products (e.g. ranitidine, cimetidine) are
eliminated only in part by this mechanism and were shown not to interact with lamivudine. The
nucleoside analogues (e.g. didanosine) like zidovudine, are not eliminated by this mechanism and are
unlikely to interact with lamivudine.

Renal clearance accounts for approximately 23% of total clearance of maraviroc when maraviroc is
administered without CYP3A4 inhibitors. In vitro studies have shown that maraviroc does not
inhibit any of the major renal uptake transporters at clinically relevant concentrations (OAT1,
OAT3, OCT2, OCTN1, and OCTN2). Additionally, co-administration of maraviroc with tenofovir
(substrate for renal elimination) and cotrimoxazole (contains trimethoprim, a renal cation transport
inhibitor), showed no effect on the pharmacokinetics of maraviroc. In addition, co-administration
of maraviroc with lamivudine/zidovudine showed no effect of maraviroc on lamivudine (primarily
renally cleared) or zidovudine (non-P450 metabolism and renal clearance) pharmacokinetics.
Maraviroc inhibits P-glycoprotein in vitro (IC50 is 183 μM). However, maraviroc does not
significantly affect the pharmacokinetics of digoxin in vivo. It may not be excluded that maraviroc
can increase the exposure to the P-glycoprotein substrate dabigatran etexilate.
