Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Binds to gamma-aminobutyric acid (GABA) type A receptors at the benzodiazepine binding site, potentiating the effect of GABA, leading to increased chloride ion influx, neuronal hyperpolarization, and inhibition of neurotransmission.
Benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and producing sedative, anxiolytic, anticonvulsant, and muscle relaxant effects.
2-6 mg orally or intravenously daily in divided doses; usual range 2-10 mg/day
0.5-2 mg orally every 6-8 hours as needed; maximum 4 mg/day. IV: 0.044 mg/kg (max 4 mg) every 6-8 hours for acute anxiety or sedation.
