Application

Phenobarbital sodium salt has been used:
  • to anesthetize mice for inducing ischemia-reperfusion injury
  • as a positive control for the activation of constitutive androstane receptor (CAR)
  • in bioluminescent yeast bioreporters (BLYAS) assay

Biochem/physiol Actions

Phenobarbital, a substituted barbituric acid is an antileptic drug and is not easily eliminated from circulation. It hyperpolarizes the synaptic neuronal membranes by favoring the activation of neuronal postsynaptic GABAA receptors by γ aminobutyric acid (GABA). Phenobarbital is also effective in treating neonatal seizures and status epilepticus.
Sedative; hypnotic; anticonvulsant; enhances GABAergic activity.
