Eight Drugs a Week, Episode 5 – TDM of antiretroviral drugs: The continuing story (of Bungalow Bill)…

This episode is about the TDM of antiretroviral drugs, an area with a boom in research output in the late 90s and early 2000s, generating enough randomized controls trials for a substantial systematic Cochrane review on the topic (a rare thing for TDM research!). It’s an ever-evolving space, but we have learned a lot through concentration monitoring, and TDM continues to be very useful in optimizing treatment. As our title suggests, this is a continuing story, and our guests, Natella Rakhmanina and Dario Cattaneo, have both been closely involved with it over their careers.


In this episode we hear about:

  • The usefulness and limitations of using TDM to monitor adherence.
  • Diverse niche patient scenarios where TDM can be very helpful, which are not at all uncommon.
  • Interesting challenges where TDM can be helpful, some that are particular to paediatric patients, and others to elderly HIV patients.
  • Learnings from TDM for long-acting drugs in psychiatry, and the implications for novel depot antiretroviral formulations.
  • Drug interaction attributable to antiretrovirals, and those that affect them.
  • Why, despite viral monitoring, TDM for antiretrovirals can still be very useful.
  • What Paxlovid tastes like.
