Tridione, a new addition to the treatment of the cerebral dysrhythmias, is helpful in the control of psychomotor seizures. While effective in certain instances if used alone, it is most helpful if used in combination with sodium diphenylhydantoinate and/or phenobarbital.Toxic symptoms are infrequent in patients who respond to the drug, and do not constitute an important contraindication to its use.Further research on the oxazolidine-2,-4-dione derivatives and related drugs may afford further advances in the therapy of epilepsy.Abstract Teaser
