Description

Curator's Comment: Description was created based on several sources, including http://www.accessdata.fda.gov/drugsatfda_docs/label/2013/020450s020lbl.pdf

Phenytoin is an anti-epileptic drug. Phenytoin has been used with much clinical success against all types of epileptiform seizures, except petit mal epilepsy. Phenytoin is a available for oral administration (tablets, capsules, suspension). CEREBYX® (fosphenytoin sodium injection) is a prodrug intended for parenteral administration; its active metabolite is phenytoin. CEREBYX should be used only when oral phenytoin administration is not possible. Although several potential targets for phenytoin action have been identified within the CNS (Na-K-ATPase, the GABAA receptor complex, ionotropic glutamate receptors, calcium channels and sigma binding sites) to date, though, the best evidence hinges on the inhibition of voltage-sensitive Na channels in the plasma membrane of neurons undergoing seizure activity.

Sample Use Guides

In Vivo Use Guide

Dilantin-125® (Phenytoin Oral Suspension, USP), each 5 ml of suspension contains 125 mg of phenytoin: Patients who have received no previous treatment may be started on one teaspoonful (5 mL) of Dilantin-125 Suspension three times daily, and the dose is then adjusted to suit individual requirements. An increase to five teaspoonfuls daily may be made, if necessary. CEREBYX® (fosphenytoin sodium injection) is a prodrug intended for parenteral administration; its active metabolite is phenytoin. 1.5 mg of fosphenytoin sodium is equivalent to 1 mg phenytoin sodium, and is referred to as 1 mg phenytoin sodium equivalents (PE). CEREBYX should be used only when oral phenytoin administration is not possible. Dosage (Status Epilepticus): The loading dose of CEREBYX is 15 to 20 mg PE/kg administered at 100 to 150 mg PE/min.

Route of Administration: Other

In Vitro Use Guide

Exposure of human adult keratinocytes (HaCaT cells) for 48 h to alkyd nanoemulsions producing phenytoin concentrations of 3.125-200 μg/mL resulted in relative cell viability readings using tetrazolium dye 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide of 100% confirming nontoxicity and suggesting cell proliferation activity.
