Advantages of the Two Proposed Naming Systems for Interchangeable Biologics (29–31)

Same Four-Letter Suffix	Different Four-Letter Suffix
• Less confusion; can mitigate medication errors • Less resistance to substitution; easier to accept designated status of interchangeability • Current tracking and safety alert systems can recognize new products	• Easier to track and associate adverse events and/or change in disease to correct product • Facilitates having accurate records of automatic substitutions (e.g., insurance-mediated switch) • Lower costs due to marketing competition of different products
