美國藥品監管的發展曆史,是一部血淚史。 中國人如果不想重複這部血淚史的話,實在應該看看。

第一個裏程碑:1906年,藥品要標明所有成分,不準添加有害成分。

The 1906 Food and Drug Act and creation of the FDA

In June 1906, President Theodore Roosevelt signed into law the Food and Drug Act, also known as the "Wiley Act" after its chief advocate.[1] 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 "mi*****randing" of food and drugs.[5] The responsibility for examining food and drugs for such "adulteration" or "mi*****randing" was given to Wiley's USDA Bureau of Chemistry.[1]


第二個裏程碑:1938年,藥品要安全,不能有虛假的功效聲稱。

The 1938 Food, Drug, and Cosmetic 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 radioactive beverages, the mascara Lash lure, which caused blindness, and worthless "cures" for diabetes and tuberculosis. The resulting proposed law was unable to get through the Congress of the United States for five years, but was rapidly enacted into law following the public outcry over the 1937 Elixir Sulfanilamide tragedy, 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 mi*****randing problem: an "Elixir" was defined as a medication dissolved in ethanol, not the diethylene glycol used in the Elixir Sulfanilamide. Had it been labeled a "solution" instead, it is argued, the agency could have done nothing to track down and confiscate what medication remained in the public's hands.[8]

President Franklin Delano Roosevelt signed the new Food, Drug, and Cosmetic Act (FD&C Act) into law on June 24, 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.[1]


第三個裏程碑:1962年,藥品除了安全還要有效(1/2/3期臨床試驗),經過FDA審批後才能上市。並且限製藥品廣告,授權FDA 檢查藥品生產商。

The 1962 Kefauver-Harris Amendment to the FD&C act represented a "revolution" in FDA regulatory authority.[10] 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.

第四個裏程碑:1984年,延長新藥的專利保護期(抵消臨床試驗產生的延誤)與降低仿製藥的臨床試驗要求

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 patent law (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.

中藥出事就是不按中醫理論用中藥,西方人拿龍膽瀉肝丸和麻黃去減肥,完全拋棄中醫理論,不出事才怪。 -kai2002- 給 kai2002 發送悄悄話 kai2002 的博客首頁 (0 bytes) () 06/16/2014 postreply 19:52:49

明白了。中藥不做臨床試驗,是怕毒副作用被檢測出來。隻要不做試驗就可以說沒有。 -26484915- 給 26484915 發送悄悄話 26484915 的博客首頁 (0 bytes) () 06/16/2014 postreply 19:02:57
