Importance of Testing Raw Materials

Drug components differ in purity, specifications and quality. According to FDA draft guidance, it's important for compounding pharmacies and outsourcing facilities to verify drug components purchased from suppliers.

Pharmacists verify drug components by:

  • reviewing the supplier's certificates of analysis (COA)s;
  • establishing reliability of the supplier's analyses through vendor qualification; and,
  • testing drug components before use in compounding.
