ARBLI vs CEFAZOLIN AND DEXTROSE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ARBLI (arbaclofen placarbil) is a prodrug of baclofen, a GABA-B receptor agonist. It acts presynaptically to inhibit excitatory neurotransmitter release and postsynaptically to reduce neuronal excitability, leading to muscle relaxation.
Bactericidal agent inhibiting bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis. Dextrose provides osmotic diuresis and energy source.
10 mg orally once daily.
1-2 g IV/IM every 8 hours; maximum 12 g/day.

Terminal elimination half-life of 26 hours (range 20-32 h), supporting once-daily dosing; prolonged in hepatic impairment.
1.8 hours (prolonged to 20-40 hours in severe renal impairment, CrCl <10 mL/min)
Primarily biliary (>70%) and fecal elimination; renal excretion accounts for <5% of unchanged drug.
Renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal (<5%)
