Emerging antiretroviral drug interactions

Abstract

With HIV-infected patients living longer and recommendations to initiate antiretrovirals (ARVs) being made earlier, the likelihood for potential drug-drug interactions between ARVs and concurrent medications used to manage co-morbid conditions will increase. In order to maximize the clinical benefit and minimize potential toxicity of ARVs and co-administered medications, it is important for clinicians to recognize significant drug-drug interactions. This article highlights clinically significant drug-drug interactions with antituberculosis agents, antimalarials, anticoagulants, chemotherapeutic agents and pulmonary antihypertensive agents when they are co-administered with newer ARVs (e.g. darunavir, raltegravir, maraviroc and etravirine).
