Switching strategies in the recent era of antiretroviral therapy

ABSTRACT Introduction: Although antiretroviral therapy is highly effective, many patients may benefit from switching strategies. Rapid advances in the development of new antiretroviral drugs could enhance the success of these approaches. In this review, we build on a previous review from 2014 and summarize the current options for switching strategies in virologically suppressed HIV-infected patients. Areas covered: We conduct a critical analysis of scientific evidence for various switching strategies used in the modern era of antiretroviral therapy, as well as reasons for these approaches, other considerations to be taken into account, and alternative strategies. Expert opinion: Current antiretroviral regimens are effective and well tolerated in HIV patients. A number of options may provide benefit to patients, even virologically suppressed patients, possibly enhancing adherence and avoiding adverse effects and toxicities. Cost reduction may also be an important goal of switching strategies. The present scenario is excellent, as many good antiretroviral compounds and regimens allow clinicians to further improve on effective treatments now used in routine practice. Even the current paradigm of triple-drug regimens as the standard of care could change, at least in some patients.
