United States Department of Health and Human Servicesand is responsible for the safety regulation of most types of foods, dietary supplements, drugs, vaccines, biological medical products, blood products, medical devices, radiation-emitting devices, veterinary products, and cosmetics. The FDA also enforces section 361 of the Public Health Service Actand the associated regulations, including sanitationrequirements on interstate travel as well as specific rules for control of disease on products ranging from pet turtlesto semendonations for assisted reproductive medicine techniques.
The FDA is an agency within the
United States Department of Health and Human Servicesresponsible for protecting and promoting the nation's public health. The FDA is headquartered in Rockville, MD with 223 field offices [cite web|url=http://www.fda.gov/oc/oms/ofm/budget/2009/Narratives/8_ORA.pdf|title=FDA 2008 ORA Field Activities|accessdate=2008-09-13|publisher=US FDA] supported by 13 laboratories located throughout the United States, the U.S. Virgin Islands, and Puerto Rico.
The agency is organized into the following major subdivisions, each focused on a major area of regulatory responsibility:
* The Office of the Commissioner (OC)
Center for Drug Evaluation and Research(CDER)
Center for Biologics Evaluation and Research(CBER)
Center for Food Safety and Applied Nutrition(CFSAN)
Center for Devices and Radiological Health(CDRH)
Center for Veterinary Medicine(CVM)
National Center for Toxicological Research(NCTR)
Office of Regulatory Affairs(ORA)
The FDA frequently works in conjunction with other Federal agencies including the Department of Agriculture,
Drug Enforcement Administration, Customs and Border Protection, and Consumer Product Safety Commission. Often local and state government agencies also work in cooperation with the FDA to provide regulatory inspections and enforcement action.
The FDA's federal budget request for 2008 totaled $2.1 billion, a $105.8 million increase from what it received in 2007. [ [http://www.fda.gov/oc/oms/ofm/budget/2008/summary.html Summary of FDA’s FY 2008 Budget ] ]
FDA is also funded by user fees submitted with
New Drug Applicationsunder the Prescription Drug User Fee Act (PDUFA)Fact|date=June 2008 in which the industry pays a fee for the review of the new product. A similar process is used for medical devices under the Medical Device User Fee and Modernization Act (MDUFMA)Fact|date=June 2008 and for animal drugs under a similar act. These fees are typically waived or reduced for small businesses.
Most federal laws administered through the FDA are codified into the Food, Drug and Cosmetic Act, [ Food, Drug and Cosmetic Act Web Version [http://www.fda.gov/opacom/laws/fdcact/fdctoc.htm] ] also called Title 21, Chapter 9 of the United States Code. Other significant laws enforced by the FDA include the
Public Health Service Act, Controlled Substances Act, and Federal Anti-Tampering Act.
The programs for FDA safety regulation vary widely by the type of product, its potential risks, and the regulatory powers granted to the agency. For example, the FDA regulates almost every facet of prescription drugs, including testing, manufacturing, labeling, advertising, marketing, efficacy and safety, yet FDA regulation of cosmetics is focused primarilly on labeling and safety. The FDA regulates most products with a set of published standards enforced by a modest number of facility inspections.
Food and dietary supplements
Center for Food Safety and Applied Nutritionis the branch of the FDA which is responsible for ensuring the safety and accurate labeling of nearly all food products in the United States. [http://www.cfsan.fda.gov/~lrd/cfsan4.html Overview of the Center for Food Safety and Applied Nutrition] One exception is meat products derived from traditional domesticated animals, such as cattle and chickens, which fall under the jurisdiction of the United States Department of Agriculture Food Safety and Inspection Service. Products which contain minimal amounts of meat are regulated by FDA, and the exact boundaries are listed in a memorandum of understanding between the two agencies. However, medicines and other products given to all domesticated animals are regulated by the FDA through a different branch, the Center for Veterinary Medicine. Other consumables which are not regulated by the FDA include beverages containing more than 7% alcohol (regulated by the Bureau of Alcohol, Tobacco, Firearms and Explosivesin the Department of Justice), and non-bottled drinking water (regulated by the United States Environmental Protection Agency(EPA)).
CFSAN's activities include establishing and maintaining food standards, such as standards of identity (for example, what the requirements are for a product to be labeled, "yogurt"). CFSAN also sets the requirements for nutrition labeling of most foods. Both food standards and nutrition labeling requirements are part of the
Code of Federal Regulations.
Dietary Supplement Health and Education Actof 1994 mandated that the FDA regulate dietary supplements as foods, rather than as drugs. Therefore, dietary supplements are not subject to safety and efficacy testing and there are no approval requirements. The FDA can take action against dietary supplements only after they are proven to be unsafe. Manufacturers of dietary supplements are permitted to make specific claims of health benefits, referred to as "structure or function claims" on the labels of these products. They may not claim to treat, diagnose, cure, or prevent disease and must include a disclaimer on the label. [http://www.fda.gov/opacom/laws/dshea.html Text of the Dietary Supplement Health and Education Act of 1994] . Accessed 5 Feb 2007.]
Bottled water is regulated in America by the FDA. [PDFlink| [http://a257.g.akamaitech.net/7/257/2422/04nov20031500/edocket.access.gpo.gov/cfr_2001/aprqtr/pdf/21cfr165.110.pdf] |106 KiB Title 21 of the Code of Federal regulations] State governments also regulate bottled water. Tap water is regulated by state and local regulations, as well as the United States EPA. FDA regulations of bottled water generally follow the guidelines established by the EPA, and new EPA rules automatically apply to bottled water if the FDA does not release an explicit new rule. [PDFlink|http://www.dwrf.info/documents/recent_dev_bw_quality.pdf|217 KiB ] Water bottlers in the US are subject to inspection similar to other food firms, but quality controls for the bottled water industry are not nearly as stringent as those for municipal water supplies.
Center for Drug Evaluation and Researchhas different requirements for the three main types of drug products: new drugs, generic drugs and over-the-counter drugs. A drug is considered "new" if it is made by a different manufacturer, uses different excipientsor inactive ingredients, is used for a different purpose, or undergoes any substantial change. The most rigorous requirements apply to "new molecular entities": drugs which are not based on existing medications.
New drugs receive extensive scrutiny before FDA approval in a process called a
New Drug Applicationor NDA. New drugs are available only by prescription by default. A change to Over the Counter (OTC) status is a separate process and the drug must be approved through an NDA first.
A drug that is approved is said to be "safe and effective when used as directed."
Advertising and promotion
The FDA reviews and regulates prescription drug advertising and promotion. (Other kinds of advertising, including for over-the- counter drugs, are regulated by the
Federal Trade Commission).The drug advertising regulation [ 21 CFR 202: Prescription Drug Advertising.] contains two key requirements. Under most circumstances, a company may only advertise a drug for the specific indication or medical use for which it was approved. "Off-label use", using a drug for other than its approved purpose, is common in medical practice. Also, an advertisement must contain "fair balance" between the benefits and risks of a drug.
Post market safety surveillance
After approval of an NDA, the sponsor must review and report to the FDA every patient adverse drug experience of which it learns. Unexpected serious and fatal adverse drug events must be reported within 15 days; other events on a quarterly basis. [21 CFR 314.80: Postmarketing Reporting of Adverse Drug Experiences] The FDA also receives directly adverse drug event reports through its MedWatch program. [MedWatch: The FDA Safety Information and Adverse Event Reporting Program [http://www.fda.gov/medwatch/index.html] . Accessed October 9, 2007] These reports are called '"spontaneous reports" because reporting by consumers and health professionals is voluntary.While this remains the primary tool of postmarket safety surveillance, FDA requirements for postmarketing risk management are increasing.As a condition of approval, a sponsor may be required to conduct additional
clinical trials, called Phase IV trials.In some cases the FDA requires risk management plans for some drugs that may provide for other kinds of studies, restrictions, or safety surveillance activities.
Generic drugs are prescription drugs whose patent protection has expired, and therefore may be manufactured and marketed by other companies.For approval of a generic drug, the FDA requires scientific evidence that the generic drug is interchangeable or therapeutically equivalent with the originally approved drug.cite web|url=http://www.fda.gov/cder/news/nightgenlett.htm|title=Therapeutic Equivalence of Generic Drugs|accessdate=2007-10- 10|publisher=U.S. Food and Drug Administration|year=1998] This is called an "ANDA" (Abbreviated New Drug Application).
Over-the-counter (OTC) drugs are drugs and combinations that do not require a doctor's prescription.The FDA has a list of approximately 800 approved ingredients that are combined in various ways to create more than 100,000 OTC drug products.Many OTC drug ingredients had been previously approved prescription drugs now deemed safe enough for use without a medical practitioner's supervision. [FDA CDER Handbook: Over-the- Counter Drug Products [http://www.fda.gov/cder/handbook/otcintro.htm] Accessed October 9, 2007]
Vaccines, blood and tissue products, and biotechnology
Center for Biologics Evaluation and Researchis the branch of the FDA responsible for ensuring the safety and efficacy of biological therapeutic agents. [ [http://www.fda.gov/cber/about.htm FDA/CBER - About CBER ] ] These include blood and blood products, vaccines, allergenics, cell and tissue-based products, and gene therapy products. New biologics are required to go through a pre-market approval process similar to that for drugs. The original authority for government regulation of biological products was established by the 1902 Biologics Control Act, with additional authority established by the 1944 Public Health Service Act. Along with these Acts, the Federal Food, Drug, and Cosmetic Actapplies to all biologic products as well. Originally, the entity responsible for regulation of biological products resided under the National Institutes of Health; this authority was transferred to the FDA in 1972.
Medical and radiation-emitting devices
Center for Devices and Radiological Health(CDRH) is the branch of the FDA responsible for the premarket approval of all medical devices, as well as overseeing the manufacturing, performance and safety of these devices. [PDFlink| [http://www.fda.gov/cdrh/radhealth/initiative/rhprogram.pdf 2005 report of the CDRH Radiological Health Program Core Group] |90.3 KiB ] The definition of a medical device is given in the FD&C Act, and it includes products from the simple toothbrushto complex devices such as implantable brain pacemakers. CDRH also oversees the safety performance of non-medical devices which emit certain types of electromagnetic radiation. Examples of CDRH-regulated devices include cellular phones, airport baggage screening equipment, television receivers, microwave ovens, tanning booths, and laser products.
CDRH regulatory powers include the authority to require certain technical reports from the manufacturers or importers of regulated products, to require that radiation-emitting products meet mandatory safety performance standards, to declare regulated products defective, and to order the recall of defective or noncompliant products. CDRH also conducts limited amounts of direct product testing.
Cosmetics are regulated by the
Center for Food Safety and Applied Nutrition, the same branch of the FDA that regulates food. Cosmetic products are not generally subject to pre-market approval by the FDA unless they make "structure or function claims" which make them into drugs (see Cosmeceutical). However, all color additives must be specifically approved by the FDA before they can be included in cosmetic products sold in the U.S. The labeling of cosmetics is regulated by the FDA, and cosmetics which have not been subjected to thorough safety testing must bear a warning to that effect.
Center for Veterinary Medicine(CVM) is the branch of the FDA which regulates food, food additives, and drugs that are given to animals, including food animals and pets. CVM does not regulate vaccines for animals; these are handled by the USDA.
CVM's primary focus is on medications that are used in food animals and ensuring that they do not affect the human food supply. The FDA's requirements to prevent the spread of
Mad Cow Diseaseare also administered by CVM through inspections of feed manufacturers.
On [December 19] , 2007, the FDA announced plans to create a database to track cloned animals through the food system and enable an effective labeling process [http://www.chron.com/disp/story.mpl/ap/fn/5392722.html] . This system will be part of the National Animal Identification System, which will track all livestock in the United States from farm to fork [http://www.thenation.com/doc/20071231/pentland_gumpert] .

Origins of federal food and drug regulation
Up until the 20th century, there were few federal laws regulating the contents and sale of domestically produced food and pharmaceuticals, with one exception being the short-lived
Vaccine Act of 1813. A patchwork of state laws provided varying degrees of protection against unethical sales practices, such as misrepresenting the ingredients of food products or therapeutic substances. The history of the FDA can be traced to the latter part of the 19th century and the U.S. Department of Agriculture's Division of Chemistry(later Bureau of Chemistry). Under Harvey Washington Wiley, appointed chief chemist in 1883, the Division began conducting research into the adulteration and misbranding of food and drugs on the American market. Although they had no regulatory powers, the Division published its findings from 1887 to 1902 in a ten-part series entitled "Foods and Food Adulterants". Wiley used these findings, and alliances with diverse organizations such as state regulators, the General Federation of Women's Clubs, and national associations of physiciansand pharmacists, to lobby for a new federal law to set uniform standards for food and drugs to enter into interstate commerce. Wiley's advocacy came at a time when the public had become aroused to hazards in the marketplace by muckraking journalists like Upton Sinclair, and became part of a general trend for increased federal regulations in matters pertinent to public safety during the Progressive Era. The 1902 Biologics Control Act was put in place after tetanus antitoxin was collected from a horse named Jim who also had diphtheria, resulting in several deaths.
The 1906 Food and Drugs Act and creation of the FDA
In June 1906, President
Theodore Rooseveltsigned into law the Food and Drug Act, also known as the "Wiley Act" after its chief advocate. The Act prohibited, under penalty of seizure of goods, the interstate transport of food which had been "adulterated", with that term referring to the addition of fillers of reduced "quality or strength", coloring to conceal "damage or inferiority," formulation with additives "injurious to health," or the use of "filthy, decomposed, or putrid" substances. The act applied similar penalties to the interstate marketing of "adulterated" drugs, in which the "standard of strength, quality, or purity" of the active ingredient was not either stated clearly on the label or listed in the "United States Pharmacopoeia" or the "National Formulary". The act also banned "misbranding" of food and drugs. [ [http://www.fda.gov/opacom/laws/wileyact.htm] Original Text of the 1906 Food and Drugs Act and Amendments] The responsibility for examining food and drugs for such "adulteration" or "misbranding" was given to Wiley's USDA Bureau of Chemistry.
Wiley used these new regulatory powers to pursue an aggressive campaign against the manufacturers of foods with chemical additives, but the Chemistry Bureau's authority was soon checked by judicial decisions, as well as by the creation of the Board of Food and Drug Inspection and the Referee Board of Consulting Scientific Experts as separate organizations within the USDA in 1907 and 1908 respectively. A 1911 Supreme Court decision ruled that the 1906 act did not apply to false claims of therapeutic efficacy, [cite court |litigants= United States v. Johnson |vol= 221 |reporter=U.S. |opinion=488 |pinpoint= |court=31 S. Ct. 627 |date=May 29, 1911, decided |url=http://web.lexis-nexis.com/universe/document?_m=45e93d4ecf899e8ddacfc1288d2b2e55&_docnum=3&wchp=dGLbVlb-zSkVA&_md5=0c2cf1f63b450204 6df1b297de555a5c ] in response to which a 1912 amendment added "false and fraudulent" claims of "curative or therapeutic effect" to the Act's definition of "misbranded." However, these powers continued to be narrowly defined by the courts, which set high standards for proof of fraudulent intent. In 1927, the Bureau of Chemistry's regulatory powers were reorganized under a new USDA body, the Food, Drug, and Insecticide organization. This name was shortened to the Food and Drug Administration (FDA) three years later. [http://www.fda.gov/opacom/backgrounders/miles.html] Milestones in U.S. Food and Drug Law History at FDA.gov]
The 1938 Food, Drug, and Cosmetics Act
By the 1930s, muckraking journalists, consumer protection organizations, and federal regulators began mounting a campaign for stronger regulatory authority by publicizing a list of injurious products which had been ruled permissible under the 1906 law, including
radioactivebeverages, cosmeticswhich caused blindness, and worthless "cures" for diabetesand tuberculosis. The resulting proposed law was unable to get through the Congress of the United Statesfor five years, but was rapidly enacted into law following the public outcry over the 1937 Elixir Sulfanilamidetragedy, in which over 100 people died after using a drug formulated with a toxic, untested solvent. The only way that the FDA could even seize the product was due to a misbranding problem: an "Elixir" was defined as a medication dissolved in ethanol, not the diethylene glycolused in the Elixir Sulfanilamide.
Franklin Delano Rooseveltsigned the new Food, Drug, and Cosmetic Act (FD&C Act) into law on June 25, 1938. The new law significantly increased federal regulatory authority over drugs by mandating a pre-market review of the safety of all new drugs, as well as banning false therapeutic claims in drug labeling without requiring that the FDA prove fraudulent intent. The law also authorized factory inspections and expanded enforcement powers, set new regulatory standards for foods, and brought cosmetics and therapeutic devices under federal regulatory authority. This law, though extensively amended in subsequent years, remains the central foundation of FDA regulatory authority to the present day.
Regulation of human drugs and medical devices after 1938
Early FD&C Act amendments: 1938-1958
Soon after passage of the 1938 Act, the FDA began to designate certain drugs as safe for use only under the supervision of a medical professional, and the category of 'prescription-only' drugs was securely codified into law by the 1951
Durham-Humphrey Amendment. While pre-market testing of drug efficacy was not authorized under the 1938 FD&C Act, subsequent amendments such as the Insulin Amendmentand Penicillin Amendmentdid mandate potency testing for formulations of specific lifesaving pharmaceuticals. The FDA began enforcing its new powers against drug manufacturers who could not substantiate the efficacy claims made for their drugs, and the 1950 Court of Appealsruling in Alberty Food Products Co. v. U.S.found that drug manufacturers could not evade the "false therapeutic claims" provision of the 1938 act by simply omitting the intended use of a drug from the drug's label. These developments confirmed extensive powers for the FDA to enforce post-marketing recalls of ineffective drugs. Much of the FDA's regulatory attentions in this era were directed towards abuse of amphetamines and barbiturates, but the agency also reviewed some 13,000 new drug applications between 1938 and 1962. While the science of toxicologywas in its infancy at the start of this era, rapid advances in experimental assays for food additive and drug safety testing were made during this period by FDA regulators and others.
Expansion of premarket approval process: 1959-1985
In 1959, Senator
Estes Kefauverbegan holding congressional hearings into concerns about pharmaceutical industry practices, such as the perceived high cost and uncertain efficacy of many drugs promoted by manufacturers. There was significant opposition, however, to calls for a new law expanding the FDA's authority. This climate was rapidly changed by the thalidomidetragedy, in which thousands of European babies were born deformed after their mothers took that drug - marketed for treatment of nausea - during their pregnancies. Thalidomide had not been approved for use in the U.S. due to the concerns of an FDA reviewer, Frances Oldham Kelsey. However, thousands of "trial samples" had been sent to American doctors during the "clinical investigation" phase of the drug's development, which at the time was entirely unregulated by the FDA. Individual members of Congress cited the thalidomide incident in lending their support to expansion of FDA authority. [ [http://www.library.arizona.edu/exhibits/udall/congrept/87th/620817.html] Report of Congressman Morris Udall on thalidomide and the Kefauver hearings.]
Kefauver-Harris Amendmentto the FD&C act represented a "revolution" in FDA regulatory authority. [cite journal |author=Temple R |year=2002 |title=Policy developments in regulatory approval |journal=Statistics in Medicine |volume=21 |pages=2939–2948 |doi=10.1002/sim.1298] The most important change was the requirement that all new drug applications demonstrate "substantial evidence" of the drug's efficacy for a marketed indication, in addition to the existing requirement for pre-marketing demonstration of safety. This marked the start of the FDA approval process in its modern form. Drugs approved between 1938 and 1962 were also subject to FDA review of their efficacy, and to potential withdrawal from the market. Other important provisions of the 1962 amendments included the requirement that drug companies use the "established" or "generic" name of a drug along with the trade name, the restriction of drug advertising to FDA-approved indications, and expansion of FDA powers to inspect drug manufacturing facilities.
One of the most important statutes in establishing the modern American pharmaceutical market was the 1984
Drug Price Competition and Patent Term Restoration Act, more commonly known as the "Hatch-Waxman Act" after its chief sponsors. This act was intended to correct two unfortunate interactions between the new regulations mandated by the 1962 amendments, and existing patentlaw (which is not regulated or enforced by the FDA, but rather by the United States Patent and Trademark Office). Because the additional clinical trials mandated by the 1962 amendments significantly delayed the marketing of new drugs, without extending the duration of the manufacturer's patent, "pioneer" drug manufacturers experienced a decreased period of lucrative market exclusivity. On the other hand, the new regulations could be interpreted to require complete safety and efficacy testing for generic copies of approved drugs, and "pioneer" manufacturers obtained court decisions which prevented generic manufacturers from even beginning the clinical trial process while a drug was still under patent. The Hatch-Waxman Act was intended as a compromise between the "pioneer" and generic drug manufacturers which would reduce the overall cost of bringing generics to market and thus, it was hoped, reduce the long-term price of the drug, while preserving the overall profitability of developing new drugs. The act extended the patent exclusivity terms of new drugs, and importantly tied those extensions, in part, to the length of the FDA approval process for each individual drug. For generic manufacturers, the Act created a new approval mechanism, the Abbreviated New Drug Application (ANDA), in which the generic drug manufacturer need only demonstrate that their generic formulation has the same active ingredient, route of administration, dosage form, strength, and pharmacokinetic properties ("bioequivalence") as the corresponding brand-name drug. This act has been credited with essentially creating the modern generic drug industry.cite journal |author=Karki L |year=2005 |title=Review of FDA Law Related to Pharmaceuticals: The Hatch-Waxman Act, Regulatory Amendments and Implications for Drug Patent Enforcement |journal=Journal of the Patent & Trademark Office Society |volume=87 |pages=602–620]
FDA reforms in the AIDS era
Concerns about the length of the drug approval process were brought to the fore early in the
AIDSepidemic. In the mid- and late 1980s, ACT-UPand other HIVactivist organizations accused the FDA of unnecessarily delaying the approval of medications to fight HIV and opportunistic infections, and staged large protests, such as a confrontational October 11, 1988 action at the FDA campus which resulted in nearly 180 arrests. [ [http://www.actupny.org/documents/cron-88.html] ACT-UP NY timeline] In August 1990, Dr. Louis Lasagna, then chairman of a presidential advisory panel on drug approval, estimated that thousands of lives were lost each year due to delays in approval and marketing of drugs for cancer and AIDS. [ Faster Approval of AIDS Drugs Is Urged, The New York Times, August 16, 1990, Thursday, Late Edition - Final, Section B; Page 12, Column 4; National Desk, 830 words, By ROBERT PEAR, Special to The New York Times, WASHINGTON, Aug. 15]
Partly in response to these criticisms, the FDA issued new rules to expedite approval of drugs for life threatening diseases, and expanded pre-approval access to drugs for patients with limited treatment options. [ [http://www.fda.gov/oashi/aids/expanded.html] FDA Website: Expanded Access and Expedited Approval of New Therapies Related to HIV/AIDS] The first of these new rules was the "IND exemption" or "treatment IND" rule, which allowed expanded access to a drug undergoing phase II or III trials (or in extraordinary cases even earlier) if it potentially represented a safer or better alternative to treatments currently available for terminal or serious illness. A second new rule, the "parallel track policy", allowed a drug company to set up a mechanism for access to a new potentially lifesaving drug by patients who for various reasons would be unable to participate in ongoing clinical trials. The "parallel track" designation could be made at the time of IND submission. The accelerated approval rules were further expanded and codified in 1992. [cite journal |author=Orlando V |year=1999 |title=The FDA's Accelerated Approval Process: Does the Pharmaceutical Industry Have Adequate Incentives for Self-Regulation? |journal=American Journal of Law and Medicine |volume=25 |pages=543–68]
All of the initial drugs approved for the treatment of HIV/AIDS were approved through accelerated approval mechanisms. For example, a "treatment IND" was issued for the first HIV drug,
AZT, in 1985, and approval was granted just two years later in 1987. [ [http://www.fda.gov/fdac/special/newdrug/speeding.html] FDA report on accelerated approval process] Three of the first five drugs targeting HIV were approved in the United States before they were approved in any other country.

Recent and ongoing reforms
Patients' rights to access unapproved drugs
A 2006 court case,
Abigail Alliance v. von Eschenbach, would have forced radical changes in FDA regulation of unapproved drugs. The Abigail Alliance argued that the FDA must license drugs for use by terminally ill patients with "desperate diagnoses," after they have completed Phase I testing. [PDFlink| [http://www.abigail-alliance.org/WLF_FDA.pdf] |119 KiB Abigail Alliance Citizen Petition to FDA] The case won an initial appeal in May 2006, but that decision was reversed by a March 2008 rehearing. The US Supreme Courtdeclined to hear the case, and the final decision denied the existence of a right to unapproved medications.
Post-marketing drug safety monitoring
The widely publicized recall of
Vioxx, a non-steroidal anti-inflammatory drugnow estimated to have contributed to fatal heart attacks in thousands of Americans, played a strong role in driving a new wave of safety reforms at both the FDA rulemaking and statutory levels. Vioxx was approved by the FDA in 1999, and was initially hoped to be safer than previous NSAIDs, due to its reduced risk of gastrointestinal tract bleeding. However, a number of pre- and post-marketing studies suggested that Vioxx might increase the risk of myocardial infarction, and this was conclusively demonstrated by results from the APPROVe trial in 2004. [ [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=15713943&query_hl=10&itool=pubmed_docsum] The APPROVe study (Pubmed)] Faced with numerous lawsuits, the manufacturer voluntarily withdrew it from the market. The example of Vioxx has been prominent in an ongoing debate over whether new drugs should be evaluated on the basis of their absolute safety, or their safety relative to existing treatments for a given condition. In the wake of the Vioxx recall, there were widespread calls by major newspapers, medical journals, consumer advocacy organizations, lawmakers, and FDA officialsPDFlink| [http://www.senate.gov/~finance/hearings/testimony/2004test/111804dgtest.pdf] |28.3 KiB David Graham's 2004 testimony to Congress] for reforms in the FDA's procedures for pre- and post- market drug safety regulation.
In 2006, a congressionally requested committee was appointed by the
Institute of Medicineto review pharmaceutical safety regulation in the U.S. and to issue recommendations for improvements. The committee was composed of 16 experts, including leaders in clinical medicinemedical research, economics, biostatistics, law, public policy, public health, and the allied health professions, as well as current and former executives from the pharmaceutical, hospital, and health insuranceindustries. The authors found major deficiencies in the current FDA system for ensuring the safety of drugs on the American market. Overall, the authors called for an increase in the regulatory powers, funding, and independence of the FDA. [cite news |first=Diedtra |last=Henderson |title=Panel: FDA needs more power, funds |work=Boston Globe |date=2006-09-23 [http://www.webcitation.org/5NkCrjdpd] ] [PDFlink| [http://books.nap.edu/execsumm_pdf/11750.pdf] |279 KiB Executive Summary of the 2006 IOM Report "The Future of Drug Safety: Promoting and Protecting the Health of the Public"] Some of the committee’s recommendations have been incorporated into drafts of the PDUFA IV bill which is expected to be passed by Congress in 2007.
Pediatric drug testing
Prior to the 1990s, only 20% of all drugs prescribed for children in the United States were tested for safety or efficacy in a pediatric population. This became a major concern of
pediatricians as evidence accumulated that the physiological response of children to many drugs differed significantly from those drugs' effects on adults. The reasons for the dearth of clinical drug testing in children were multifactorial. For many drugs, children represented such a small proportion of the potential market, that drug manufacturers did not see such testing as cost-effective. Also, because children were thought to be ethically restricted in their ability to give informed consent, there were increased governmental and institutional hurdles to approval of these clinical trials, as well as greater concerns about legal liability. Thus, for decades, most medicines prescribed to children in the U.S. were done so in a non-FDA-approved, "off-label" manner, with dosages "extrapolated" from adult data through body weight and body-surface-area calculations.
An initial attempt by the FDA to address this issue was the 1994 FDA Final Rule on Pediatric Labeling and Extrapolation, which allowed manufacturers to add pediatric labeling information, but required drugs which had not been tested for pediatric safety and efficacy to bear a disclaimer to that effect. However, this rule failed to motivate many drug companies to conduct additional pediatric drug trials. In 1997, the FDA proposed a rule to require pediatric drug trials from the sponsors of New Drug Applications. However, this new rule was successfully preempted in Federal court as exceeding the FDA's statutory authority. While this debate was unfolding, Congress used the 1997
Food and Drug Administration Modernization Actto pass incentives which gave pharmaceutical manufacturers a six-month patent term extension on new drugs submitted with pediatric trial data. The act reauthorizing these provisions, the 2002 Best Pharmaceuticals for Children Act, allowed the FDA to request NIH-sponsored testing for pediatric drug testing, although these requests are subject to NIH funding constraints. Most recently, in the Pediatric Research Equity Actof 2003, Congress codified the FDA's authority to mandate manufacturer-sponsored pediatric drug trials for certain drugs as a "last resort" if incentives and publicly funded mechanisms proved inadequate.cite journal |author=Politis P |year=2005 |title=Transition From the Carrot to the Stick: The Evolution of Pharmaceutical Regulations Concerning Pediatric Drug Testing |journal=Widener Law Review |volume=12 |pages=271]
Rules for generic biologics
Since the 1990s, many successful new drugs for the treatment of
cancer, autoimmune diseases, and other conditions have been protein-based biotechnology drugs, regulated by the Center for Biologics Evaluation and Research. Many of these drugs are extremely expensive; for example, the anti-cancer drug Avastincosts $55,000 for a year of treatment, while the enzyme replacement therapydrug Cerezyme costs $200,000 per year, and must be taken by Gaucher's Diseasepatients for life. Biotechnology drugs do not have the simple, readily verifiable chemical structures of conventional drugs, and are produced through complex, often proprietary techniques, such as transgenic mammalian cell cultures. Because of these complexities, the 1984 Hatch-Waxman Act did not include biologics in the Abbreviated New Drug Application(ANDA) process, essentially precluding the possibility of generic drug competition for biotechnology drugs. In February 2007, identical bills were introduced into the House [ [http://www.webcitation.org/5Nz4qt1oo] H. R. 1038: Access to Life-Saving Medicine Act. (Introduced 2/14/2007)] and Senate [ [http://www.webcitation.org/5Nz4sPPMP] S. 623: Access to Life-Saving Medicine Act. (Introduced 2/14/2007)] with bipartisan cosponsorship to create an ANDA process for the approval of generic biologics. The bills face opposition from biologic drug manufacturers, and other lawmakers are working to create compromise legislation. [ [http://www.webcitation.org/5Nz6SMDEP] Pear R.

The FDA currently has regulatory oversight over a large array of products that affect the health and life of American citizens. [http://www.fda.gov/oc/history/historyoffda/section1.html] A History of the FDA at FDA.gov] As a result, the FDA's powers and decisions are carefully monitored by several governmental and non-governmental organizations. There are many criticisms and complaints lodged against the FDA from patients, economists, regulatory bodies, and the pharmaceutical industry.
Regulation of living organisms
With acceptance of premarket notification 510(k) 033391 in January 2004, the FDA granted Dr. Ronald Sherman permission to produce and market
Medical maggotsfor use in humans or other animals as a prescription medical device in a medical procedure known as maggot therapyThe specific indications the FDA has allowed Medical maggotsto be employed in are as follows:
"For debriding non-healing necrotic skin and soft tissue wounds, including pressure ulcers, venous stasis ulcers, neuropathic foot ulcers, and non-healing traumatic or post surgical wounds."
Medical maggotsrepresent the first living organism ever allowed by the Food and Drug Administration for production and marketing as a prescription medical device.
In June 2004, the FDA cleared leeches (Hirudo medicinalis) as the second living organism to be used in modern medicine as medical devices. Surgeons who do plastic and reconstructive surgery find leeches especially valuable when regrafting amputated appendages, such as fingers or toes. Severed veins in such cases often are too damaged or too small to reconnect. In these cases, pooled blood around a wound can threaten tissue survival. The primary function of leeches is to drain the pooled blood and increase the chances of survival of the tissue in reattached appendages.
