Fosphenytoin is a disodium phosphate ester of 3-hydroxy-methyl-5,5 diphenylhydantoin, which is rapidly and completely converted to phenytoin (conversion half-life, 8-15 minutes)
Fosphenytoin is the disodium phosphate ester of phenytoin and is converted to phenytoin by phosphatases in the blood and various organs, principally liver
Fosphenytoin is a prodrug of phenytoin, which means it converts to phenytoin once it enters the body

Despite its higher cost and minor adverse effects when compared The median time-to-discharge difference between IV phenytoin vs IM fosphenytoin was 1:49 hours (95% confidence interval, 1:24-2:24 hours; P <
Its main mechanism is to block frequency-dependent, use-dependent and voltage-dependent neuronal sodium channels, and therefore limit repetitive firing of action The 2 study groups had similar baseline characteristics for neonatal variables as well as maternal antenatal complications
