Drug interactions in people with HIV treated with antivirals for other viral illnesses.

INTRODUCTION

Background

People with HIV (PWH) have benefited tremendously from effective antiretroviral(ARV) treatments. However, PWH are at increased risk for other viral infections transmitted in the same way as HIV (such as hepatitis C and MPox) or that are opportunistic (e.g. cytomegalovirus). These coinfections contribute significantly to morbidity and mortality among PWH and require effective treatments to optimize patient outcomes. However, their management is complicated by drug-drug interactions (DDIs) with ARVs.

AREAS COVERED: Metabolism pathways and DDIs between approved ARVs and selected antiviral agents used for the treatment of common and clinically relevant viral coinfections are discussed. Literature review included search of published papers, conference abstracts (IAS, CROI, IDWeek, EACS, Glasgow) as well as unpublished data from approved drug prescribing information and regulatory submissions sourced from PubMed, Google, and Google Scholar available between June 30 1981 through June 1, 2024.

EXPERT OPINION: Management of drug interactions is essential for maintaining efficacy and safety of ARV and other co-administered antiviral therapies. Longer acting agents are now available for treatment of HIV and this lengthens the period during which drug interactions may occur. Emerging novel nanoparticle-carrier targeted hepatitis C and HIV treatments may mitigate, if not eliminate, their propensity for drug-drug interactions.
