Summary
Letermovir increases pitavastatin concentrations, and the effect is magnified when cyclosporine is also given. This raises the risk of myopathy and rhabdomyolysis.
What this interaction means in plain words
Letermovir and Pitavastatin 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.
Letermovir belongs to Anti Virals; Pitavastatin belongs to Cardiovascular.
Why it happens
Letermovir inhibits hepatic uptake transporters OATP1B1/3, raising pitavastatin exposure.
What to do
Avoid coadministration where possible; it is contraindicated if cyclosporine is also used. Otherwise, consider holding the statin during letermovir therapy and monitor for muscle toxicity.
