Summary
Eslicarbazepine may lower saquinavir concentrations, risking virologic failure and resistance. Saquinavir exposure is highly dependent on CYP3A4.
What this interaction means in plain words
Eslicarbazepine and Saquinavir can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
CYP3A4 induction by eslicarbazepine increases saquinavir metabolism.
What to do
Use a non-inducing antiepileptic where possible. If combined, monitor viral load and consider saquinavir level monitoring.
