CENTRAX vs LORAZEPAM INTENSOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to benzodiazepine site on GABA-A receptors, enhancing chloride ion influx and hyperpolarization of neurons, resulting in anxiolytic, sedative, and muscle relaxant effects.
Benzodiazepine that enhances GABA-A receptor activity by increasing the frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
10-30 mg orally, 3-4 times daily.
0.5-2 mg orally every 6-8 hours as needed. Maximum 4 mg/day.

60-120 hours (mean 100 hours); long half-life leads to accumulation upon multiple dosing and prolonged sedation.
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in elderly (15-20 hours) and patients with hepatic impairment (up to 30-40 hours).
Renal (primarily as glucuronide conjugates; <1% unchanged); biliary/fecal: minimal (less than 5%).
Renal excretion of glucuronide conjugates; <1% unchanged drug excreted renally. Fecal elimination accounts for approximately 10% of administered dose.
