Compaction process for manufacture of sodium phenytoin dosage form

摘要

A process for the roller compaction and manufacture of a pharmaceutical formulation comprises the steps of adding sodium phenytoin to a vessel of a blender and adding at least one excipient to the vessel. The mixture is blended and transferred to a roller compactor, where pressure is applied to the blend of sodium phenytoin and excipient. Next, the resultant compaction is milled to form a granulation, which is blended a second time and is suitable for further processing into a dosage form. Preferably, the excipients include magnesium stearate, sugar, lactose monohydrate, and talc. In an alternative embodiment, talc is added immediately prior to the granulation being blended for a second time.
