A-POXIDE vs PAXIPAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GABA-A receptor positive allosteric modulator; increases chloride ion influx and neuronal hyperpolarization.
PAXIPAM (flurazepam) is a benzodiazepine that enhances GABA-A receptor activity by binding to the benzodiazepine site, increasing chloride ion conductance and producing CNS depression.
GERD: 20 mg orally once daily for 4-8 weeks. Erosive esophagitis: 40 mg once daily for 8 weeks. H. pylori eradication: 20 mg twice daily with amoxicillin and clarithromycin for 14 days.
5-10 mg orally every 8-12 hours as needed; maximum 40 mg/day.

Terminal elimination half-life is 12-18 hours (mean 15 hours) in adults with normal renal function. Prolonged to 24-36 hours in elderly or moderate renal impairment (CrCl < 50 mL/min).
Terminal elimination half-life is 30-40 hours in healthy adults; prolonged in elderly and hepatic impairment.
Renal excretion accounts for 60-70% of elimination, predominantly as unchanged drug. Biliary/fecal excretion accounts for 20-30%, with approximately 10% eliminated in feces as metabolites.
Renal excretion of unchanged drug and glucuronide metabolites accounts for 60-70%; fecal excretion accounts for 20-30%.
