According to the Federal Register Notice that announced the guidance revision (here), the FDA notes that “This revised draft guidance reflects the FDA’s intent to recognize the differences between outsourcing facilities and conventional drug manufacturers and to tailor CGMP requirements to the nature of the specific compounding operations conducted by outsourcing facilities while maintaining the minimum standards necessary to protect patients from the risks of contaminated or otherwise substandard drug products.” The FR Notice also provides additional background on its thinking in making the revisions to the draft guidance.
