DescriptionAn anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of gamma-aminobutyric acid receptor responses. [PubChem]

Pharmacology
IndicationClonazepam is used as an anticonvulsant in the treatment of the Lennox-Gastaut syndrome (petit mal variant), akinetic and myoclonic seizures. It can also be used for the treatment of panic disorders.
Structured Indications
PharmacodynamicsClonazepam, a benzodiazepine, is used primarily as an anticonvulsant in the treatment of absence seizures, petit mal variant seizures (Lennox-Gastaut syndrome), akinetic and myoclonic seizures, and nocturnal myoclonus. It enhances the activity of gamma aminobutyric acid (GABA), which is a major inhibitory neurotransmitter in the central nervous system. In animals, convulsions are antagonized occurs following administration of clonazepam. In humans, clonazepam suppresses the spike and wave discharge in absence seizures (petit mal) and decreases the frequency, amplitude, duration, and spread of discharge in minor motor seizures.
Mechanism of actionAllosteric interactions between central benzodiazepine receptors and gamma-aminobutyric acid (GABA) receptors potentiate the effects of GABA. As GABA is an inhibitory neurotransmitter, this results in increased inhibition of the ascending reticular activating system. Benzodiazepines, in this way, block the cortical and limbic arousal that occurs following stimulation of the reticular pathways.

AbsorptionClonazepam is rapidly and completely absorbed after oral administration. The absolute bioavailability of clonazepam is about 90%. Cmax, oral administration = 1 -4 hours.
Volume of distributionNot Available
Protein binding85% bound to plasma proteins.
Metabolism

Hepatic (cytochrome P450, including CYP3A). Biotransformation occurs mainly by reduction of the 7-nitro group to the 4-amino derivative. This derivative can be acetylated, hydroxylated, and glucuronidated.

Route of eliminationClonazepam is highly metabolized, with less than 2% unchanged clonazepam being excreted in the urine. Metabolites of Klonopin are excreted by the kidneys. Clonazepam also undergoes acetylation via NAT2.
Half life30-40 hours
ClearanceNot Available
ToxicitySomnolence, confusion, coma, and diminished reflexes. The most commonly reported adverse event when clonazepam is used for seizure disorders is CNS depression. LD50, oral, rats = >15000 mg/kg.

General Function:
Inhibitory extracellular ligand-gated ion channel activity
Specific Function:
Component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the vertebrate brain. Functions also as histamine receptor and mediates cellular responses to histamine. Functions as receptor for diazepines and various anesthetics, such as pentobarbital; these are bound at a separate allosteric effector binding site. Functions as ligand-gated chloride channel (By similarity).

General Function:
Cholesterol binding
Specific Function:
Can bind protoporphyrin IX and may play a role in the transport of porphyrins and heme (By similarity). Promotes the transport of cholesterol across mitochondrial membranes and may play a role in lipid metabolism (PubMed:24814875), but its precise physiological role is controversial. It is apparently not required for steroid hormone biosynthesis. Was initially identified as peripheral-type benz...

General Function:
Toxic substance binding
Specific Function:
Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc.
