One of the less acknowledged tools in the international guidelines of combination antiretroviral therapy (cART) for HIV-1 infection is therapeutic drug monitoring (TDM). Yet anywhere there is a Clinical Pharmacology Unit or other facility for measuring plasma drug concentrations, physicians often measure the plasma levels of antiretrovirals as well as of comedications and find it useful. The aim of this article is to provide an overview of how relevant it is for a clinician to assess individual drug levels. Moreover we wanted to investigate to what extent the field is already assisted by web-based tools (i.e.: drug interaction charts). Finally we tried to look how pharmacogenetics may reduce the need for TDM, and whether this diagnostics is cost-effective.
We searched PubMed by “drug interactions and HIV”, “drug level and HIV”, “therapeutic drug monitoring”, and we investigated the Liverpool Drug Interaction website, the DHHS Guidelines website, the UCSF website, and the AETC online Guide for HIV/AIDS Clinical care. Furthermore, we assessed the role that the main national and international guidelines for antiretroviral treatment attributed to TDM and searched for the various clinical subsets in which drug monitoring is particularly relevant.
Finally, we suggest that cross-sectional studies of subjects failing therapy or experiencing drug-related adverse events, as well as longitudinal studies of particular conditions, may show the importance of problem-targeted rather than routine TDM.
