Metabolite Identification

Common Name

Phenobarbital

Description

Phenobarbital is only found in individuals that have used or taken this drug. It is a barbituric acid derivative that acts as a nonselective central nervous system depressant.Phenobarbital acts on GABAA receptors, increasing synaptic inhibition. This has the effect of elevating seizure threshold and reducing the spread of seizure activity from a seizure focus. Phenobarbital may also inhibit calcium channels, resulting in a decrease in excitatory transmitter release. The sedative-hypnotic effects of phenobarbital are likely the result of its effect on the polysynaptic midbrain reticular formation, which controls CNS arousal.
