Amobarbital, Serum
Clinical Information: Amobarbital is an intermediate-acting barbiturate with hypnotic properties
used in short-term treatment of insomnia and to reduce anxiety and provide sedation preoperatively. (1, 2)
Amobarbital is administered by intravenous infusion or intramuscular injection. The duration of its
hypnotic effect is about 6 to 8 hours. The drug distributes throughout the body, with a volume of
distribution of 0.9 to 1.4 L/kg, and about 59% of a dose is bound to plasma proteins. Metabolism takes
place in the liver primarily via hepatic microsomal enzymes. Its half-life is about 15 to 40 hours (mean: 25
hours). Excretion occurs mainly in the urine. (2, 3)
Useful For: Monitoring amobarbital therapy
Interpretation: The therapeutic range of amobarbital is 1 to 5 mcg/mL, with toxicity typically
associated with concentrations >10 mcg/mL. (2)
Reference Values:
Therapeutic concentration: 1.0-5.0 mcg/mL
Toxic concentration: >10.0 mcg/mL
Concentration at which toxicity occurs varies and should be interpreted in light of clinical situation.
