MIDOZALAM HYDROCHLORIDE vs PAXIPAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Midazolam hydrochloride is a benzodiazepine that enhances the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA-A receptor, resulting in increased chloride ion conductance, neuronal hyperpolarization, and inhibition of neuronal transmission. This produces sedative, anxiolytic, amnestic, and anticonvulsant effects.
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.
2.5-10 mg IV bolus for induction; 0.05-0.2 mg/kg/h IV infusion for sedation. IM: 0.07-0.08 mg/kg (max 5 mg) 30-60 min pre-procedure.
5-10 mg orally every 8-12 hours as needed; maximum 40 mg/day.

Terminal elimination half-life: 1.5-3 hours in healthy adults; prolonged in elderly (up to 6 hours), obesity, hepatic cirrhosis (up to 20 hours), and congestive heart failure.
Terminal elimination half-life is 30-40 hours in healthy adults; prolonged in elderly and hepatic impairment.
Renal excretion of metabolites (approximately 90% as glucuronide conjugates, with less than 1% unchanged drug) and biliary/fecal excretion (approximately 5-10%).
Renal excretion of unchanged drug and glucuronide metabolites accounts for 60-70%; fecal excretion accounts for 20-30%.
