Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Acyclic nucleotide analog of adenosine monophosphate; inhibits hepatitis B virus (HBV) DNA polymerase by competing with the natural substrate dATP, causing DNA chain termination after incorporation into viral DNA.
Remdesivir is a nucleotide analog prodrug that, after intracellular metabolism, incorporates into nascent viral RNA chains causing synthesis termination and inhibition of RNA-dependent RNA polymerase (RdRp). It targets the SARS-CoV-2 RdRp with selectivity over human RNA polymerases.
10 mg orally once daily.
200 mg IV on Day 1, then 100 mg IV once daily for 5 to 10 days.

Terminal elimination half-life is approximately 6-9 hours in patients with normal renal function. In renal impairment, half-life is prolonged (up to 18 hours in moderate impairment, >30 hours in severe impairment). Steady-state is achieved within 5-7 days.
Remdesivir: ~1 hour (parent); GS-441524: ~27 hours (terminal). Context: GS-441524 accumulation may occur with daily dosing.
Primarily renal; 70-90% of an oral dose is excreted unchanged in urine via active tubular secretion and glomerular filtration. Biliary/fecal elimination accounts for <5%.
Renal: 10% unchanged remdesivir; 49% as metabolite GS-441524; 18% as other metabolites. Fecal: 47.5% as metabolites. Biliary: minor.
