Until recently, most ordinary people had never heard of “pharmacy compounding.” Then, a number of deaths and illnesses caused by a drug that was compounded in a Framingham, Massachusetts pharmacy propelled drug compounding to the national spotlight (see, e.g., Denise Grady et al., Scant Oversight of Drug Maker in Fatal Meningitis Outbreak, N.Y. Times, Oct. 6, 2012).
Compounding is the practice of preparing a drug for an individual patient’s needs, and is used when those needs cannot be met by a mass-produced drug. See Thompson v. Western States Medical Center, 535 U.S. 357, 360 (2002). For example, if a patient is allergic to a particular excipient (inactive ingredient) in an FDA-approved medicine, a doctor may order a special compounding pharmacy to prepare the medicine without that excipient. Because of the very small scale of compounding, Congress in 1997 attempted to exempt (via 21 U.S.C. § 353a) the industry from a number of provisions of the Food Drug and Cosmetic Act, including the requirement to submit a new drug application prior to interstate sale (21 U.S.C. § 355), the requirement that the drug labeling bear “adequate directions for use” (21 U.S.C. § 352(f)(1)), and the need to strictly follow good manufacturing practices, or GMP (see 21 U.S.C. § 351(a)(2)(B)). A number of controls on compounding were included, however, such as the requirement that there be a valid prescription from a licensed practitioner (21 U.S.C. § 353a(a)(1)), that the drug be compounded by a licensed pharmacist (or physician) (21 U.S.C. § 353a(a)(1)), and that the drug be compounded from ingredients that meet certain quality standards (21 U.S.C. § 353a(b)(1)(A)–(B)).
However, § 353a—and with it, all of the provisions and exemptions just mentioned—was held unconstitutional in its entirety in Western States Medical Center v. Shalala, 238 F.3d 1090 (9th Cir. 2001), aff’d 535 U.S. 357 (2002), on the basis of certain restrictions on free speech that were also contained within the statute and which, according to the Ninth Circuit, could not be severed from the remaining provisions because “Congress intended to exempt compounding from the FDCA’s requirements only in return for a prohibition on promotion of specific compounded drugs.” See 535 U.S. at 366. Thereafter, the FDA promulgated a policy by which it would primarily “defer to state authorities regarding less significant violations” but would enforce a number of provisions relating to ingredient standards, unapproved substances, commercial scale production, adulteration, and promotion. The FDA made clear that its enforcement activities “need not be limited to” these or any particular areas, however, thus negating any expectations that Congress’ now-invalidated exemptions might nevertheless provide a safe harbor through the weight of influence, if not law. Since then, the FDA has in fact exercised oversight of compounding pharmacies, as is evident from the handfuls of warning letters that it sends to non-compliant facilities each year. These letters have addressed, for example, promotion that made unsubstantiated efficacy claims, contamination, and the large-scale manufacture of what were essentially copies of FDA-approved drugs.
