OZOBAX DS vs PARAFLEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Baclofen, a gamma-aminobutyric acid (GABA) analog, acts as an agonist at GABA-B receptors in the spinal cord, leading to decreased excitatory neurotransmitter release and reduced muscle spasticity.
Centrally acting muscle relaxant; inhibits polysynaptic reflexes at the spinal cord level, possibly by depressing the central nervous system.
Adults: 600 mg orally twice daily; if efficacy not achieved after 2–3 weeks, may increase to 600 mg three times daily.
250-500 mg orally once daily, may increase to 500 mg twice daily if needed. Maximum 500 mg/day.

Terminal elimination half-life is 1.0-1.5 hours in patients with normal renal function; prolonged to 8-12 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 2–3 hours, allowing for multiple daily dosing.
Renal: 70-80% unchanged; fecal: 20-30%; biliary: <5%
Renal excretion of unchanged drug and metabolites accounts for approximately 50% of an oral dose; fecal excretion accounts for about 20%.
