Study Overview

Brief Summary

The purpose of this study is to understand how the different formulation of phenytoin is taken up into the blood in Healthy Adults.

This study is seeking healthy adult participants. All the study participants will receive Phenytoin 50 mg chewable tablets manufactured at Ascoli and Vega Baja manufacturing site.

We will measure how the phenytoin will be taken up into the blood in Healthy Adults following oral dosing of Phenytoin.

This will help us determine if the Phenytoin 50 mg chewable tablets manufactured at Ascoli and Vega Baja manufacturing site are similar or not.
