Class 1 antiarrhythmics inhibit the fast Na channels in non-nodal myocardial tissues and are subdivided into 3 categories (A, B, and C) on the basis of their speed of dissociation from the Na channels and electrophysiologic effects. All drugs in class 1 reduce cardiac conduction velocity to some degree by slowing phase 0 depolarization.Abstract. Fetal hydantoin syndrome is a rare disorder that is believed to be caused by exposure of a fetus to the anticonvulsant drug phenytoin. The classic features of fetal hydantoin syndrome include craniofacial anomalies, prenatal and postnatal growth deficiencies, underdeveloped nails of the fingers and toes, and mental retardation.The risk for neuropsychiatric effects is greater for people with a history of psychiatric problems or learning difficulties. The serum concentration of brivaracetam can decrease with the concomitant use of CYP450 inducers, such as phenytoin, carbamazepine, and phenobarbital.

On the other hand, levetiracetam can lead to agitation in some patients. Pregnancy is a critical factor when prescribing AEDs, as certain antiepileptics, such as valproic acid and phenytoin, are known teratogens. Notably, phenytoin is a Na channel blocker and P450 inducer, associated with complications like cardiac arrhythmias and SJS/TENS.Phenytoin is a highly effective anticonvulsant medication that is considered to be the treatment of choice for generalized major motor and focal epileptic seizures. An understanding of the pharmacokinetic properties of phenytoin greatly facilitates the management of seizure patients.
