Which formulation of Phenytoin can be administered IV and IM?

Cerebyx, also known as fosphenytoin, is a prodrug that is converted to phenytoin in the body. Its formulation allows for intravenous (IV) and intramuscular (IM) administration, making it suitable for situations where quick and effective anticonvulsant treatment is necessary, such as in the case of status epilepticus. IV and IM routes are advantageous because they provide rapid absorption and response, which is critical in emergencies.

The other options, such as chewable tablets, capsules, and sprinkle capsules, are designed for oral administration only. They do not provide the flexibility needed for urgent medical scenarios where IV or IM delivery is essential. Therefore, Cerebyx stands out as the correct choice due to its unique formulation that supports both IV and IM routes, ensuring prompt therapeutic action for patients requiring immediate seizure control.
