Name: | Clonazepam |
---|---|
PubChem Compound ID: | 11493440 |
Description: | An 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. |
Molecular formula: | C15H10ClN3O3 |
Molecular weight: | 318.69 g/mol |

Pharmacology: | Clonazepam, 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. |
Mechanism of Action: |
Allosteric 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 fo...

Absorption: | Clonazepam is rapidly and completely absorbed after oral administration. The absolute bioavailability of clonazepam is about 90%. |
Protein binding: | 85% |
Biotransformation: | 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 elimination: | Clonazepam is highly metabolized, with less than 2% unchanged clonazepam being excreted in the urine. Metabolites of Klonopin are excreted by the kidneys |
Half Life: | 30-40 hours |
Toxicity: | Somnolence, confusion, coma, and diminished reflexes |
Affected organisms: | Humans and other mammals |
