Chemical Properties

White or almost white, crystalline powder, slightly hygroscopic.





brand name

Diphenylan (Lannett); Phenytek (Mylan); Phenytex (Watson) [Name previously used: Diphenylhydantoin Sodium.].

General Description

Phenytoin sodium, 5,5-diphenyl-2,4-imidazolidinedione, 5,5-diphenylhydantoin,diphenyl-hydantoin sodium (Dilantin), has been used fordecades in the control of grand mal types of epilepticseizure. It is structurally analogous to the barbiturates butdoes not possess their extensive sedative properties. Thecompound is available as the sodium salt. Solutions for parenteraladministration contain 40% propylene glycol and10% alcohol to dissolve the sodium salt.

Clinical Use

Phenytoin sodium’s cardiovascular effects were uncoveredduring observation of toxic manifestations of the drugin patients being treated for seizure disorders. Phenytoinsodium was found to cause bradycardia, prolong the PRinterval, and produce T-wave abnormalities on electrocardiograms.It is a class IB antiarrhythmic agent. Today,phenytoin sodium’s greatest clinical use as an antiarrhythmicdrug is in the treatment of digitalis-induced arrhythmias.34 Its action is similar to that of lidocaine. It depressesventricular automaticity produced by digitalis, without adverseintraventricular conduction. Because it also reversesthe prolongation of AV conduction by digitalis, phenytoinsodium is useful in supraventricular tachycardias caused bydigitalis intoxication.

Safety Profile

Confirmed carcinogen. Experimental teratogen. Other experimental reproductive effects. Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: anorexia, respiratory depression, nausea or vomiting, hemorrhage, dermatitis, and endocrine effects. Mutation data reported. An anticonvulsant and cardiac depressant used for the treatment of grand mal and psychomotor seizures. When heated to decomposition it emits very toxic fumes of NOx and Na2O.


Phenytoin and its sodium salt are reasonably anticipated to be human carcinogens based on sufficient evidence from studies in experimental animals.
