Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits viral DNA polymerase and DNA synthesis of herpes simplex virus (HSV-1 and HSV-2).
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.
Apply a thin layer to the affected area 5 times daily for 4 days.
40 mg orally once as a single dose; for patients weighing ≥80 kg, 80 mg orally once as a single dose.

Due to minimal systemic absorption, an elimination half-life cannot be accurately determined in humans. Following intravenous administration in animals, the terminal half-life is approximately 10 hours, but this is not clinically relevant for topical use.
The terminal elimination half-life of baloxavir marboxil is approximately 79.1 hours (range 53–107 hours), supporting single-dose therapy for influenza.
Docosanol is minimally absorbed after topical application; systemic absorption is negligible. Any absorbed drug is primarily metabolized and excreted via bile and feces. Renal excretion is insignificant. Less than 1% of the applied dose enters systemic circulation, and nearly all elimination occurs via biliary/fecal routes.
Baloxavir marboxil is primarily excreted via feces (80.1%) and urine (14.7%) after oral administration, with <1% as unchanged drug in urine.
