ANSPOR vs ARBLI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cephalexin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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.
250-500 mg orally every 6 hours for 10-14 days; maximum 4 g/day.
10 mg orally once daily.

1.5–2 hours in adults with normal renal function; prolonged to 20–30 hours in severe renal impairment (CrCl <10 mL/min)
Terminal elimination half-life of 26 hours (range 20-32 h), supporting once-daily dosing; prolonged in hepatic impairment.
Primarily renal (90–95%) as unchanged drug via glomerular filtration and tubular secretion; biliary excretion negligible (<1%)
Primarily biliary (>70%) and fecal elimination; renal excretion accounts for <5% of unchanged drug.
