General description

Clobazam is a benzodiazepine, comprising of B ring nitrogen placed in positions 1 and 5 contrary to 1,4-benzodiazepines. It is a ligand for γ-aminobutyric acid type A (GABAA) receptor and is metabolized by cytochrome P450 in the liver.

Application

Clobazam has been used as a benzodiazepine to test its effect on the activation of the human immunodeficiency virus type 1 (HIV-1) long terminal repeat (LTR).

Biochem/physiol Actions

Anxiolytic; ligand for the GABAA receptor benzodiazepine modulatory site.
Clobazam interacts at α and γ2 subunits junction of the GABAA receptor. It is less sedative and elicits anxiolytic and anticonvulsant effects. Clobazam is more selective on the α2 subunit of the GABAA receptor than the α1 subunit. It is an antiseizure drug and is associated with antiepileptic activity. Clobazam is useful in treating chronic epileptic encephalopathy disorder, Lennox‐Gastaut syndrome. It is employed in epilepsy and seizure prevention adjunctive therapy.
