On September 10, 2018, the federal Food & Drug Administration (”FDA”) released its revised draft standard Memorandum of Understanding (“MOU”) between states and the FDA addressing the interstate distribution of compounded drug products.  See 83 Fed. Reg. 175, 45631 et seq. (Sept. 10, 2018). The draft is the latest in the FDA’s decades-long effort to clarify state and federal roles in investigating and responding to complaints related to compounded drug products shipped between states.
