Case 23. Managing Directly (Inter)Acting Medications
Download MP3Chris presents a 62-yr-old man with HIV for >30 yrs, with viral suppression and many drug resistance mutations, whose ART must be changed due to a drug-drug interaction, but also for simplification. As part of their discussion, Chris and Eileen review reasons to change ART regimens, and work through the evidence-based options for this patient based on his history and resistance mutations profile.
