However, the availability of generic lamivudine in the context of the current economic crisis has raised a new issue in some Spanish public hospitals: breaking up the once-daily FDAC of efavirenz/tenofovir/emtricitabine, tenofovir/emtricitabine, or abacavir/lamivudine, in order to administer their components separately and thus allowing the use of generic lamivudine instead of branded emtricitabine or lamivudine. Thus, the change is not that of an ART based on a brand FDAC towards a bioequivalent generic FDAC, but of a brand FDAC towards the separated components, generic or branded, included in the coformulation. This brings up a new challenge in the history of ART.</p><p id="par0030" class="elsevierStylePara elsevierViewall">This paper attempts to determine the legal, economic, and ethical implications associated with a change in the treatment of HIV-1-infected subjects receiving a FDAC, and particularly those receiving a once-daily STR, to a split treatment administering the components separately, including generic surrogates of some components.
