Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antisense oligonucleotide that binds to mRNA of human cytomegalovirus (HCMV), inhibiting viral replication by blocking protein synthesis.
Baloxavir marboxil is a prodrug that is converted to baloxavir acid, which inhibits the cap-dependent endonuclease activity of the influenza virus polymerase acidic protein, thereby preventing viral mRNA transcription and replication.
Intravitreal injection: 330 mcg (0.05 mL of 6.6 mg/mL solution) every 2 weeks for 2 doses, then every 4 weeks.
40 mg orally once as a single dose; for patients weighing ≥80 kg, 80 mg orally once as a single dose.

Terminal elimination half-life is approximately 2 hours in patients with normal renal function. In patients with renal impairment, half-life may be prolonged up to 10 hours.
The terminal elimination half-life of baloxavir marboxil is approximately 79.1 hours (range 53–107 hours), supporting single-dose therapy for influenza.
Primarily renal excretion. Approximately 40% of the dose is excreted unchanged in urine within 24 hours. Biliary/fecal excretion accounts for less than 5%.
Baloxavir marboxil is primarily excreted via feces (80.1%) and urine (14.7%) after oral administration, with <1% as unchanged drug in urine.
