Risk of HIV Escape using Sub-Optimal Antiretroviral Dual or Monotherapy

Budget constrictions have pushed some researchers to explore whether antiretroviral therapy with one or two drugs instead of the well-established triple-drug regimens may be able to maintain undetectable viremia in HIV-infected individuals, at least used as simplification in patients already with viral suppression under standard triple therapy. With the advent of co-formulations and the improved safety of the newest antiretroviral agents, there is no other reason than cost to justify moving from triple to dual or monotherapy.
