Product Description:
Fosphenytoin sodium is a water-soluble phosphate ester prodrug of phenytoin developed for intravenous and intramuscular administration. It is rapidly converted to phenytoin in the body and is used in the acute management of seizure disorders, particularly convulsive status epilepticus. Compared to intravenous phenytoin, fosphenytoin offers improved safety and tolerability, with a reduced risk of local tissue injury and cardiovascular complications.
In the United States, fosphenytoin sodium is approved for short-term use, typically for five days or fewer, in the treatment of epilepsy when oral or standard phenytoin administration is not feasible or is contraindicated. This includes clinical situations such as status epilepticus, repeated or cluster seizures, endotracheal intubation, persistent vomiting, or cases where the patient is unresponsive or unable to swallow.
Due to its rapid onset of action and flexible administration routes, fosphenytoin sodium is widely utilized in emergency and critical care settings. Its predictable conversion to phenytoin allows effective seizure control while providing enhanced safety during acute neurological emergencies.
