FUZEON vs LETERMOVIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fusion inhibitor; binds to gp41 of HIV-1, preventing conformational changes required for fusion with host CD4+ T-cell membrane.
Letermovir is an antiviral agent that inhibits the human cytomegalovirus (CMV) terminase complex, specifically the pUL56 subunit, thereby preventing viral DNA processing and packaging.
90 mg subcutaneously twice daily
480 mg orally once daily (two 240 mg tablets).

Terminal elimination half-life: 3.8 hours; clinically, steady-state plasma concentrations are achieved within 2-3 days with subcutaneous administration
Clinical Note
moderateLetermovir + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Letermovir."
Clinical Note
moderateLetermovir + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Letermovir."
Clinical Note
moderateLetermovir + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Letermovir."
Clinical Note
moderateLetermovir + Dronedarone
The terminal elimination half-life is approximately 12 hours (range 10–18 hours) in healthy subjects, allowing once-daily dosing.
Renal: approximately 70% as unchanged drug via glomerular filtration; fecal: <5% as metabolites
Letermovir is primarily eliminated via biliary/fecal excretion (approximately 93% of the dose recovered in feces, with <2% as unchanged drug) and renal excretion accounts for <7% (mostly as metabolites, <1% unchanged).
