He also reported phenytoin to prevent intracellular increase of sodium caused by maximal electroshock seizures and by hyponatremia
Data from a randomized, double-blind, placebo-controlled trial in patients with serious head trauma support the use of phenytoin to prevent posttraumatic

DILANTIN (phenytoin) is related to the barbiturates in chemical structure, but has a five-membered ring
However, newer antiepileptic drugs (AEDs) have emerged as safer alternatives for the suppression of seizures
In 1908 phenytoin (5,5-diphenylhydantoin) was first synthesized as a barbiturate derivative in Germany by professor Heinrich Biltz (1865–1943) and subsequently resynthesized by an American chemist of the pharmaceutical company Parke-Davis in 1923 in Detroit
The primary site of action appears to be the motor cortex where spread of seizure activity is inhibited
The interval between first drug exposure and symptoms is usually 2–4 weeks but has been reported in individuals receiving anticonvulsants for 3 or more months

Phenytoin and phenytoin sodium, oral
The generally accepted mechanism for the synthesis of phenytoin considers the intermediacy of potassium ureate (A), 12b a stronger nucleophile than urea (Scheme 2a)

Phenytoin, which was discovered in 1938, was the first anti-seizure medication and is still being used to control seizures
Recent evidence suggests that phenytoin inhibits dysfunctional RyR2, reduces
CYP2C9 (major) and CYP2C19 (minor), thus several drugs may inhibit or induce the

This action leads to a delay in neuronal electrical recovery from inactivation
Phenytoin is highly protein-bound and is metabolized by cytochrome P450 (CYP) enzymes, in addition to
