Chapter 16 The Food and Drug Administration

FDA Prehistory • 1862, President Lincoln appointed first director of Department of Agriculture • 1883 Request for petition to pass laws prohibiting adulteration & misbranding of foods and drugs. • For serious drinking, the drugstore was the place to go. Lydia E. Pinkham's Vegetable Compound, a popular nostrum for women, was depending on the formula, 15 to 20 percent alcohol (VU).

Advertising Cards • A common method for medicine-makers to hawk their products was to provide druggists with postcard-sized advertisements with a picture on one side and a description of the glories of the product on the other. • Ayer's Sarsaparilla • Dr. Morse's Indian Root Pills • Hires' Root Beer • Lydia E. Pinkham's Vegetable Compound (First Card) • Lydia E. Pinkham's Vegetable Compound (Second Card) • Pond's Extract • Rumford Yeast Powder • Wells, Richardson, & Co. 's Lactated Food http: //www. mc. vanderbilt. edu/biolib/hc/nostrums/cards. html

The Jungle, Upton Sinclair, 1906 …with the hot weathere descended upon Packingtown a veritable Egyptian plague of flies; there could be no describing this--the houses would be black with them. There was no escaping; you might provide all your doors and windows with screens, but their buzzing outside would be like the swarming of bees, and whenever you opened the door they would rush in as if a storm of wind were driving them. (Chapter 10)

FDA History • 1906: FDA formed, banned interstate commerce in adulterated misbranded food, drink, and drugs • 1938 107 deaths of (primarily) children due to ingestion of Elixir of Sulfanilamide, a toxic combination of diethylene glycol and sulfa. • =>1938 Federal Food, Drug and Cosmetic Act

FDA Act 1938 • requiring that new drugs be shown to be safe before marketing. • extending FDA’s control to cosmetics and therapeutic devices. • authorizing factory inspections and standards of identity for food staples. • eliminating a requirement to prove intent to defraud in drug misbranding cases. • adding court injunctions to the previous penalties of seizures and prosecutions

Drug Testing Guidelines: 1. Chemical Composition 2. Acute toxicity studies in two species 3. Chronic toxicity studies with different doses in different species 4. Observation of animals 5. Pathological examination of animals 6. Studies on the absorption and elimination of the chemical 7. Study of interactions 8. Knowledge of idiosyncrasies and untoward reactions

The Crystaldyne Pain Reliever, 1996 Similar to The Stimulator is essentially an electric gas barbecue grill igniter outfitted with finger grips. When pressed against the skin, the devices sparks and causes a small electric shock. Makers of the device claim it can relieve headaches, back pain, arthritis, stress, menstrual cramps, earaches, sinus, nosebleeds, flu and other ailments. Because of its medical claims, the Stimulator is considered a medical device. The manufacturers, however, have not complied with any FDA regulations that govern the marketing of medical devices. The companies have submitted no information to FDA showing that the device is either safe or effective. . .

FDA History Continued • 1962 sale/use of thalidomide banned in U. S. based upon thousands of birth defects, primarily in Europe & South America – amendment for efficacy & safety • 1969 – hearings re injuries (10, 000) & deaths (731) in a 10 year period [heart valves, pacemakers, IUDs, … (Nader)]

FDA History Continued • => 1976 Medical Device Amendments [new=> review, old=>grandfathered, new equivalent=>grandfathered] • =>1978 Good Manufacturing Practices • =>1984 Medical Device Reporting • =>1988 Device Recall/Rebuild • =>1990 Safe Medical Devices

FDA History Continued • =>1992 Medical Device Amendments [tracking, surveillance, reporting, refund, . . ] • =>1997 Modernization Act: …public health is a responsibility shared by the entire health care community. The law directs the agency to carry out its mission in consultations and cooperation with all FDA stakeholders, including consumer and patient groups, the regulated industry, health care professionals, and FDA’s regulatory counterparts abroad…

Labeling …FDA (also) regulates the labeling of products under its jurisdiction. This information, which must be rigorously truthful, well documented, and not misleading, plays a major role in protecting consumers and the public health. The FDAregulated food label is helping shoppers eat a healthy diet; the labeling of drugs and medical devices gives prescribers and patients reliable guidance about the safety and effectiveness of health care products.

Recent TV Ad (October 2001) • • (several photos of couples, …) 3 bottles of male virility compounds! Free three month supply, 3 bottles! Simply pay $8. 50 shipping and handling charges for each bottle! • No health claims are made for these pills in accordance with FDA regulations.

A medical device is: "an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related article, including a component part, or accessory which is: - recognized in the official National Formulary, or the United States Pharmacopoeia, or any supplement to them, - intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals, or - intended to affect the structure or any function of the body of man or other animals, and which does not achieve any of it's primary intended purposes through chemical action within or on the body of man or other animals and which is not dependent upon being metabolized for the achievement of any of its primary intended purposes.
