Excipient sourcing: function, grade and documents
Excipient selection starts with the intended functional role and dosage-form process. The same broad excipient name can cover grades with different physical and processing characteristics.

Frequently asked questions
Are excipient grades with the same name equivalent?
Not necessarily. Physical properties, manufacturing controls and documentation can differ, so equivalence requires your technical and quality review.
Can MRT Materials review a current comparison grade?
Yes. Share the current product reference and the critical attributes that must be maintained for the sourcing review.
