Foreløbige kliniske data tyder på, at den adefovirforbundne resistensmutation rtA181V kan medføre nedsat følsomhed over for lamivudin, og at den lamivudinforbundne mutation rtA181T kan medføre reduceret følsomhed over for adefovirdipivoxil.
Preliminary clinical data suggest the adefovir-associated resistance mutation rtA181V may confer a reduced susceptibility to lamivudine, and the lamivudine-associated mutation rtA181T may confer a reduced susceptibility to adefovir dipivoxil.
