ALPRAZOLAM vs LIBERVANT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Positive allosteric modulator of GABA-A receptors; enhances GABA inhibitory neurotransmission by binding to benzodiazepine site on GABA-A receptor, increasing chloride ion conductance.
GABA-A receptor positive allosteric modulator; enhances inhibitory neurotransmission.
0.25-0.5 mg orally 3 times daily; maximum 4 mg/day in divided doses.
0.25 mg intravenously over 2 minutes, may repeat once after 15 minutes if inadequate response; maximum total dose 0.5 mg.

12-15 hours (mean ~13 hours); prolonged in elderly (up to 19 hours) and hepatic impairment (up to 20-30 hours); clinical context: allows once- to twice-daily dosing, but risk of accumulation with high doses or in vulnerable populations
Clinical Note
moderateAlprazolam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Alprazolam is combined with Fluticasone propionate."
Clinical Note
moderateAlprazolam + Haloperidol
"The risk or severity of adverse effects can be increased when Alprazolam is combined with Haloperidol."
Clinical Note
moderateAlprazolam + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Alprazolam."
Clinical Note
moderateAlprazolam + Erythromycin
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).
Renal (approximately 80% as metabolites, <20% unchanged); fecal (minor, ~7%)
Primarily renal excretion of unchanged drug (approximately 85%) and glucuronide conjugates (approximately 10%); biliary/fecal excretion accounts for less than 5%.
