You should never skip any doses and finish the full course of treatment even if you feel better as stopping the medication without talking to the doctor may cause non-stop seizures and can endanger life.

It controls seizures or fits by decreasing the abnormal and excessive activity of the nerve cells in the brain.

Indications

• Epilepsy/Seizures

Mechanism of action

Fosphenytoin is a diphosphate ester salt of phenytoin which acts as a water soluble prodrug of phenytoin. After admin, plasma esterases convert fosphenytoin to phosphate, formaldehyde, and phenytoin as the active moiety; phenytoin stabilises neuronal membranes and decreases seizure activity by increasing efflux or decreasing influx of Na ions across cell membranes in the motor cortex during generation of nerve impulses.
