LORAZ vs MIDAZOLAM HYDROCHLORIDE PRESERVATIVE FREE
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 neuronal hyperpolarization.
2-6 mg orally or intravenously daily in divided doses; usual range 2-10 mg/day
0.5-2 mg slow IV over 2 minutes, may repeat q2-3min; typical total dose 2.5-5 mg. IM: 0.07-0.08 mg/kg (usual 5 mg).

Terminal elimination half-life: 12–15 hours in healthy adults. Extended in elderly (15–20 hours), hepatic impairment (up to 50 hours), and obesity.
Clinical Note
moderateClorazepic acid + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Clorazepic acid is combined with Fluticasone propionate."
Clinical Note
moderateLorazepam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Lorazepam is combined with Fluticasone propionate."
Clinical Note
moderateLorazepam + Haloperidol
"The risk or severity of adverse effects can be increased when Lorazepam is combined with Haloperidol."
Clinical Note
moderateTerminal elimination half-life is 1.8-2.5 hours in healthy adults. In critically ill patients or those with hepatic impairment, half-life may extend to 2-6 hours. Obesity may prolong half-life due to increased volume of distribution.
Renal: ~85% as glucuronide conjugates and ~10% as unchanged drug. Biliary/fecal: ~5%.
Primarily renal elimination of hydroxylated metabolites (midazolam 1-hydroxymidazolam and 4-hydroxymidazolam) as glucuronide conjugates. Only 0.03% of unchanged drug is excreted renally. Fecal excretion accounts for <2%.
