Only in vitro interaction studies are available. In these,<unk>  used the concentrative nucleoside transporter 1 (CNT1) and equilibrative nucleoside transporters 1 (ENT1) and 2 (ENT2). Drugs that interact with these transporters could influence blood plasma concentrations of<unk> . Being a thymidine phosphorylase inhibitor,<unk>  could also interact with substrates of this enzyme such as zidovudine. For the eye drops,<unk>  absorption is negligible, rendering interactions basically irrelevant.
