At a glance
Clonazepam is a benzodiazepine used for the treatment of epilepsy (seizures), panic disorder, and anxiety disorder.
Indications
- Panic disorder (with or without agoraphobia)
- Lennox-Gastaut Syndrome (petit mal variant)
- Akinetic and myoclonic seizures
- Absence seizures (petit mal) - in patients who have failed to respond to succinimides
Pharmacology
Clonazepam exhibits pharmacological properties which are common to benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects. The central actions of benzodiazepines are mediated through an enhancement of the GABAergic neurotransmission at inhibitory synapses. In the presence of benzodiazepines the affinity of the GABA receptor for the neurotransmitter is enhanced through positive allosteric modulation resulting in an increased action of released GABA on the postsynaptic transmembrane chloride ion flux.
