| Common Name | Phenytoin methylcatechol |
|---|
| Description | Phenytoin methylcatechol belongs to the class of organic compounds known as phenylhydantoins. These are heterocyclic aromatic compounds containing an imiazolidinedione moiety substituted by a phenyl group. Phenytoin acts to suppress the abnormal brain activity seen in seizure by reducing electrical conductance among brain cells by stabilizing the inactive state of voltage-gated sodium channels. Phenytoin methylcatechol is an extremely weak basic (essentially neutral) compound (based on its pKa). phenytoin methylcatechol and S-adenosylhomocysteine can be biosynthesized from phenytoin catechol and S-adenosylmethionine; which is mediated by the enzyme catechol O-methyltransferase. In humans, phenytoin methylcatechol is involved in the metabolic disorder called the phenytoin (antiarrhythmic) action pathway. It is sometimes considered a class 1b antiarrhythmic. Aside from seizures, it is an option in the treatment of trigeminal neuralgia in the event that carbamazepine or other first-line treatment seems inappropriate. Phenytoin sodium is a commonly used antiepileptic. Phenytoin methylcatechol is a metabolite of phenytoin. |
