MIDAZOLAM HYDROCHLORIDE (AUTOINJECTOR) vs TEMAZ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Midazolam is a short-acting benzodiazepine that potentiates GABA-A receptor activity by binding to the benzodiazepine site, enhancing chloride ion conductance and neuronal hyperpolarization, leading to anxiolytic, sedative, amnestic, anticonvulsant, and muscle relaxant effects.
Temazepam, a benzodiazepine, enhances the effect of gamma-aminobutyric acid (GABA) at the GABA-A receptor, increasing chloride ion conductance and causing neuronal hyperpolarization, leading to anxiolytic, sedative, and hypnotic effects.
10 mg intramuscularly once via autoinjector for acute seizure control.
Temazepam 15-30 mg orally at bedtime, up to 60 mg if needed.

Terminal elimination half-life is 1.8–6.4 hours (mean ~3 hours) in healthy adults; prolonged in elderly, obese, hepatic impairment (up to 15–20 hours), and critical illness.
Terminal elimination half-life: 1.5–2 hours; in severe renal impairment (CrCl <30 mL/min), half-life may extend to 4–6 hours, requiring dose adjustment.
Renal excretion of metabolites (glucuronide conjugates) accounts for approximately 90% of elimination; less than 1% excreted unchanged; minimal fecal excretion (< 5%).
Renal: ~80% as unchanged drug and metabolites; biliary/fecal: ~20%.
