              Pharmacology

              Mechanism of Action

              Binds receptors at several sites within the CNS, including the limbic system and reticular formation. Effects may be mediated through the GABA receptor system. Increase in neuronal membrane permeability to chloride ions enhances the inhibitory effects of GABA; the shift in chloride ions causes hyperpolarization (less excitability) and stabilization of the neuronal membrane

              Absorption

              Bioavailability: Slow and erratic following IM admin

              Onset: 1-5 min (IV)

              Duration: 15-60 min (IV)

              Plasma peak time: Within 2 hr

              Distribution

              Protein bound: 90-98%

              Vd: 3.3 L/kg

              Metabolism

              Metabolites: Demoxepam, desmethylchlordiazepoxide, desmethyldiazepam, oxazepam

              Elimination

              Half-life: 6-25 hr (normal liver and renal function); 5-30 hr (end-stage renal disease); 30-63 hr (liver cirrhosis)
