Metabolite Identification
Common Name4-Hydroxyphenytoin glucuronide
Description4-Hydroxyphenytoin glucuronide, also known as HPPH glucuronide, belongs to the class of organic compounds known as phenylhydantoins. These are heterocyclic aromatic compounds containing an imiazolidinedione moiety substituted by a phenyl group. 4-Hydroxyphenytoin glucuronide is a metabolite of phenytoin. 4-Hydroxyphenytoin glucuronide is an extremely weak basic (essentially neutral) compound (based on its pKa). 4-hydroxyphenytoin glucuronide and uridine 5'-diphosphate can be biosynthesized from hydroxyphenytoin and uridine diphosphate glucuronic acid through its interaction with the enzymes UDP-glucuronosyltransferase 1-1, UDP-glucuronosyltransferase 1-4, UDP-glucuronosyltransferase 1-6, and UDP-glucuronosyltransferase 1-9. In humans, 4-hydroxyphenytoin glucuronide 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 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.
