LIBERVANT vs LORAZEPAM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GABA-A receptor positive allosteric modulator; enhances inhibitory neurotransmission.
Benzodiazepine that enhances GABA-A receptor activity by increasing frequency of chloride channel opening, leading to neuronal hyperpolarization and inhibition.
0.25 mg intravenously over 2 minutes, may repeat once after 15 minutes if inadequate response; maximum total dose 0.5 mg.
2-3 mg orally or IV, 3-4 times daily; maximum 10 mg/day. For anxiety, 0.5-2 mg orally 2-3 times daily. For procedural sedation, IV: 0.044 mg/kg or 2 mg total, may repeat.

Terminal elimination half-life is approximately 2–4 hours in patients with normal renal function; may be prolonged up to 8–12 hours in severe renal impairment (CrCl <30 mL/min).
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
moderateLorazepam + Probenecid
"The serum concentration of Probenecid can be increased when it is combined with Lorazepam."
Clinical Note
moderateLorazepam + Clemastine
Terminal elimination half-life is 12-18 hours. Clinically significant for once-daily dosing; may accumulate in elderly or hepatic impairment.
Primarily renal excretion of unchanged drug (approximately 85%) and glucuronide conjugates (approximately 10%); biliary/fecal excretion accounts for less than 5%.
Primarily renal excretion as glucuronide conjugates; less than 1% excreted unchanged. Approximately 60-80% eliminated in urine, with 15-20% in feces.
