• Drug Groups: approved
• Description: An anticonvulsant that is used in a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs. [PubChem]
• Indication: For the control of generalized tonic-clonic (grand mal) and complex partial (psychomotor, temporal lobe) seizures and prevention and treatment of seizures occurring during or following neurosurgery.
• Pharmacology: Phenytoin is an antiepileptic drug which can be useful in the treatment of epilepsy. The primary site of action appears to be the motor cortex where spread of seizure activity is inhibited. Phenytoin reduces the maximal activity of brain stem centers responsible for the tonic phase of tonic-clonic (grand mal) seizures. Phenytoin acts to dampen the unwanted, runaway brain activity seen in seizure by reducing electrical conductance among brain cells. It lacks the sedation effects associated with phenobarbital. There are some indications that phenytoin has other effects, including anxiety control and mood stabilization, although it has never been approved for those purposes by the FDA. Phenytoin is primarily metabolized by CYP2C9.
• Toxicity: Oral, mouse: LD₅₀ = 150 mg/kg; Oral, rat: LD₅₀ = 1635 mg/kg. Symptoms of overdose include coma, difficulty in pronouncing words correctly, involuntary eye movement, lack of muscle coordination, low blood pressure, nausea, sluggishness, slurred speech, tremors, and vomiting.
• Affected Organisms: Humans and other mammals
• Biotransformation: Primarily hepatic
• Absorption: Bioavailability 70-100% oral, 24.4% for rectal and intravenous administration. Rapid rate of absorption with peak blood concentration expected in 1½ to 3 hours.
• Half Life: 22 hours (range of 7 to 42 hours)
• Protein Binding: Highly protein bound, 90%
• Elimination: Most of the drug is excreted in the bile as inactive metabolites which are then reabsorbed from the intestinal tract and excreted in the urine. Urinary excretion of phenytoin and its metabolites occurs partly with glomerular filtration but, more importantly, by tubular secretion.

Research Area: Neurological Disease
Biological Activity:
Phenytoin (Lepitoin; NSC 8722; Phenytek; Phenytoine; Sodanton; Zentropi) is an inactive voltage-gated sodium channel stabilizer. Phenytoin (Lepitoin; NSC 8722; Phenytek; Phenytoine; Sodanton; Zentropi) blocks voltage-dependent sodium channels to inhibit propagation from active electrical foci, an effect more useful for nontoxicological seizures. Phenytoin (Lepitoin; NSC 8722; Phenytek; Phenytoine; Sodanton; Zentropi) acts to suppress the abnormal brain activity seen in seizure by reducing electrical conductance among brain cells. Aside from seizures, Phenytoin sodium (Lepitoin; NSC 8722; Phenytek; Phenytoine; Sodanton; Zentropi) is an option in the treatment of trigeminal neuralgia in the event that carbamazepine or other 1st line treatment is deemed inappropriate.
