CENTRAX vs MIDAZOLAM
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.
Midazolam is a benzodiazepine that potentiates gamma-aminobutyric acid (GABA) activity by binding to the benzodiazepine site on GABA-A receptors, enhancing GABA's inhibitory effects, leading to increased chloride ion conductance, hyperpolarization, and neuronal inhibition.
10-30 mg orally, 3-4 times daily.
IV: 0.5-2 mg initial, titrate by 0.5-1 mg increments every 2-3 min; typical total 2.5-5 mg. IM: 0.07-0.08 mg/kg (usual 5 mg). Oral: 7.5-15 mg as a single premedication dose.

Clinical Note
moderateMidazolam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Midazolam is combined with Fluticasone propionate."
Clinical Note
moderateMidazolam + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Midazolam."
Clinical Note
moderateMidazolam + Erythromycin
"The serum concentration of Erythromycin can be increased when it is combined with Midazolam."
Clinical Note
moderateMidazolam + Cyclosporine
60-120 hours (mean 100 hours); long half-life leads to accumulation upon multiple dosing and prolonged sedation.
Terminal elimination half-life: 1.5-2.5 hours in healthy adults; prolonged in elderly (5-6 hours), obesity, hepatic cirrhosis (up to 20 hours), and critical illness.
Renal (primarily as glucuronide conjugates; <1% unchanged); biliary/fecal: minimal (less than 5%).
Renal: approximately 45-57% as metabolites (primarily 1-hydroxymidazolam glucuronide) and <1% unchanged; fecal: 2-10% via biliary excretion.
