Clonazepam

Overview

Basic Info

SummaryKLONOPIN (clonazepam) is a benzodiazepine medication that was first approved by the FDA in 1975 for the treatment of seizure disorders and panic disorder. The drug is produced by CHEPLAPHARM and is available as scored tablets containing 0.5 mg of clonazepam, and unscored tablets containing 1 mg or 2 mg of clonazepam. Clonazepam is a GABAA receptor agonist, which means that it enhances the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that slows down brain activity, resulting in its calming effects. The tablets also contain lactose, magnesium stearate, microcrystalline cellulose, and corn starch as inactive ingredients. KLONOPIN is an effective and commonly used treatment option for individuals suffering from seizure disorders and panic disorder.
