Dilantin dī´lăntĭn [key], trade name for diphenylhydantoin, an anticonvulsant drug. The first nonsedative antiepileptic agent, it is still widely used to control the grand mal type of epilepsy . It is also useful against types of psychomotor epilepsy, i.e., epilepsy involving bizarre patterns of movement. In some cases Dilantin, in combination with phenobarbital, a barbiturate , is more effective than either drug used alone.
