Medicine Description phenytoin-el-nasr 50mg
Phenytoin 50mg Capsule is a medication that primarily stabilizes neuronal membranes and decreases the excitability of the brain's nerve cells. It achieves this by selectively inhibiting voltage-gated sodium channels during the action potential phase of neurons. By prolonging the inactivation phase of these channels, phenytoin reduces the influx of sodium ions, which in turn diminishes repetitive neuronal firing and helps stabilize electrical activity in the brain. This action is crucial for controlling seizures and preventing their occurrence.

Patient Advice and Precautions
Patients should have their blood levels monitored regularly to prevent toxicity. It's important to inform healthcare providers of any other medications being taken, as phenytoin can interact with various drugs. Patients should not abruptly discontinue the medication without consulting their doctor, as this can lead to increased seizure frequency. Additionally, maintaining good oral hygiene is vital to reduce the risk of gingival hyperplasia.
