What is Fosphenytoin Sodium?

Fosphenytoin Sodium is a water-soluble prodrug of phenytoin, primarily used for the management of generalized convulsive status epilepticus and for the short-term prevention and treatment of seizures during neurosurgery. It is administered parenterally and rapidly converts to phenytoin in the body, offering a more predictable pharmacokinetic profile and reduced risk of local tissue toxicity compared to intravenous phenytoin.
