Fosphenytoin is a prodrug of phenytoin and its anticonvulsant effects are attributable to phenytoin. It is thought to work by modulating voltage-dependent sodium channels of neurons, inhibiting calcium flux across neuronal membranes, modulating voltage-dependent calcium channels of neurons, and enhancing sodium-potassium ATPase activity of neurons and glial cells. 

Fosphenytoin Sodium Injection is available as 75mg/mL (50mg phenytoin sodium equivalents [PE]/mL), packaged in 100mg PE/2mL and 500mg PE/10mL single-use vials.
