Clonazepam, sold under the brand name Klonopin, is a prescription medication that belongs to the class of drugs known as benzodiazepines. It is primarily used for the treatment of seizures and panic disorder, as well as certain types of anxiety disorders.

Clonazepam works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that helps to reduce excessive brain activity and promote a calming effect. By increasing GABA activity, clonazepam helps to reduce seizures and alleviate symptoms of panic and anxiety disorders.

Clonazepam is available in tablet form and is typically taken orally. The dosage and frequency of clonazepam use are determined by a healthcare professional based on the individual's condition and response to treatment.
