CLOBAZAM vs LIBRIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clobazam is a benzodiazepine that enhances the effect of GABA at the GABA-A receptor, increasing chloride ion conductance and neuronal hyperpolarization. It has a high affinity for the α2 subunit, which may contribute to its anticonvulsant effects.
Binds to benzodiazepine site on GABA-A receptor, potentiating GABAergic inhibition and increasing chloride ion conductance.
10-60 mg orally once daily, divided into two doses. Typical starting dose: 10 mg twice daily.
5-25 mg orally 3-4 times daily; or 50-100 mg intramuscularly or intravenously initially, then 25-50 mg 3-4 times daily as needed.

Clobazam: 36–42 hours; N-desmethylclobazam: 71–82 hours. Steady state achieved in 5–10 days.
Clinical Note
moderateClobazam + Estrone sulfate
"The serum concentration of Estrone sulfate can be decreased when it is combined with Clobazam."
Clinical Note
moderateClobazam + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Clobazam is combined with Fluticasone propionate."
Clinical Note
moderateClobazam + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Clobazam."
Clinical Note
moderateClobazam + Erythromycin
Terminal elimination half-life of chlordiazepoxide is 24-48 hours; active metabolite desmethyldiazepam has half-life of 36-200 hours; with repeated dosing, effective half-life extends due to accumulation of active metabolites.
Renal: ~82% as metabolites (mainly N-desmethylclobazam and hydroxylated metabolites), unchanged clobazam <1%; fecal: ~11%.
Renal excretion of unchanged drug and metabolites (primarily glucuronide conjugates of chlordiazepoxide and demoxepam, <2% unchanged); approximately 60-70% of a dose appears in urine as metabolites, with 4-9% in feces via biliary elimination.
