The regulation of therapeutic goods, that is drugs and therapeutic devices, varies by jurisdiction. In some countries, such as the United States, they are regulated at the national level by a single agency. In other jurisdictions they are regulated at the state level, or at both state and national levels by various bodies, as is the case in Australia.
The role of therapeutic goods regulation is designed mainly to protect the health and safety of the population. Regulation is aimed at ensuring the safety, quality, and efficacy of the therapeutic goods which are covered under the scope of the regulation. In most jurisdictions, therapeutic goods must be registered before they are allowed to be marketed. There is usually some degree of restriction of the availability of certain therapeutic goods depending on their risk to consumers.
Modern drug regulation has historical roots in the response to the proliferation of universal antidotes which appeared in the wake of Mithridates' death. Mithridates had brought together physicians, scientists, and shamans to concoct a potion that would make him immune to poisons. Following his death, the Romans became keen on further developing the Mithridates potion's recipe. Mithridatium re-entered western society through multiple means. The first was through the Leechbook of the Bald (Bald's Leechbook), written somewhere between 900 and 950, which contained a formula for various remedies, including for a theriac. Additionally, theriac became a commercial good traded throughout Europe based on the works of Greek and Roman physicians.
The resulting proliferation of various recipes needed to be curtailed in order to ensure that people were not passing off fake antidotes, which led to the development of government involvement and regulation. Additionally, the creation of these concoctions took on ritualistic form and were often created in public and the process was observed and recorded. It was believed that if the concoction proved unsuccessful, it was due to the apothecaries’ process of making them and they could be held accountable because of the public nature of the creation.
In the 9th century, many Muslim countries established an office of the hisba, which in addition to regulating compliance to Islamic principles and values took on the role of regulating other aspects of social and economic life, including the regulation of medicines. Inspectors were appointed to employ oversight on those who were involved in the process of medicine creation and were given a lot of leigh weigh to ensure compliance and punishments were stringent. The first official 'act', the 'Apothecary Wares, Drugs and Stuffs' Act (also sometimes referred to as the 'Pharmacy Wares, Drugs and Stuffs' Act) was passed in 1540 by Henry VIII and set the foundation for others. Through this act, he encouraged physicians in his College of Physicians (founded by him in 1518) to appoint four people dedicated to consistently inspecting what was being sold in apothecary shops. In conjunction with this first piece of legislation, there was an emergence of standard formulas for the creation of certain ‘drugs’ and ‘antidotes’ through Pharmacopoeias which first appeared in the form of a decree from Frederick II of Sicily in 1240 to use consistent and standard formulas. The first modern pharmacopoeias were the Florence Pharmacopoeia published in 1498, the Spanish Pharmacopoeia published in 1581 and the London Pharmacopoeia published in 1618.
In the United States, regulation of drugs was originally a state right, as opposed to federal right. But with the increase in fraudulent practices due to private incentives to maximize profits and poor enforcement of state laws, increased the need for stronger federal regulation. President Roosevelt signed the Federal Food and Drug Act (FFDA) in 1906 which established stricter standards. A 1911 Supreme Court decision, United States vs. Johnson, established that misleading statements were not covered under the FFDA. This directly led to Congress passing the Sherley Amendment which established a clearer definition of ‘misbranded’.
Another key catalyst for advances in drug regulation were certain catastrophes that served as calls to the government to step in and impose regulations that would prevent repeats of those instances. One such instance occurred in 1937 when more than a hundred people died from using sulfanilamide elixir which had not gone through any safety testing. This directly led to the passing of the Federal, Food, Drug, and Cosmetic Act in 1938. One other major catastrophe occurred in the late 1950s when Thalidomide, which was originally sold in Germany (introduced into a virtually unregulated market) and eventually sold around the world, led to approximately 100,000 babies being born with various deformities.
The UK's Chief Medical Officer had established a group to look into safety of drugs on the market in 1959 prior to the crisis and was moving in the direction of address the problem of unregulated drugs entering the market. The crisis created a greater sense of emergency to establish safety and efficacy standards around the world. The UK started a temporary Committee on Safety of Drugs while they attempted to pass more comprehensive legislation. Though compliance and submission of drugs to the Committee on Safety of Drugs was not mandatory immediately after, the pharmaceutical industry larger complied due to the thalidomide situation. The European Economic Commission also passed a directive in 1965 in order to impose greater efficacy standards before marketing a drug. The United States congress passed the Drug Amendments Act of 1962 The Drug Amendments Act required the FDA to ensure that new drugs being introduced to the market had passed certain tests and standards. Both the EU and US acts introduced the requirements to ensure safety and efficacy. Of note, increased regulations and standards for testing actually led to greater innovation in pharmaceutical research in the 1960s, despite greater preclinical and clinical standards.
In 1989, the International Conference of Drug Regulatory Authorities organized by the WHO, officials from around the world discussed the necessity for streamlined processes for global drug approval.
Various other events throughout history have demonstrated the importance of drug and medicine regulation keeping up with scientific advances. In 2006, the challenges associated with TGN 1412 highlighted the shortcomings of animal models and paved the way for further advances in regulation and development for biological products. Rofecoxib represents a drug that was on the market that had not clearly represent the risks associated with the use drug which led to the concept of 'risk management planning' within the field of regulation by introducing the need to understand how various safety concerns would be managed. Various cases over recent years have demonstrated the need for regulation to keep up with scientific advances that have implications for people's health.
Therapeutic goods in Australia are regulated by the Therapeutic Goods Administration (TGA). The availability of drugs and poisons is regulated by scheduling under individual state legislation, but is generally under the guidance of the national Standard for the Uniform Scheduling of Drugs and Poisons (SUSDP).
Under the SUSDP, medicinal agents generally belong to one of five categories:
In Canada, regulation of therapeutic goods are governed by the Food and Drug Act and associated regulations. In addition, the Controlled Drugs and Substances Act requires additional regulatory requirements for controlled drugs and drug precursors.
The regulation of drugs in China is governed by the China Food and Drug Administration.
German law classifies drugs into
Medicines for Human Use in the United Kingdom are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). The availability of drugs is regulated by classification by the MHRA as part of marketing authorisation of a product.
The United Kingdom has a three-tiered classification system:
Within POM, certain agents with a high abuse/addiction liability are also separately scheduled under the Misuse of Drugs Act 1971 (amended with the Misuse of Drugs Regulations 2001); and are commonly known as Controlled Drugs (CD).
Medicines in Norway are divided into five groups:
Class A Narcotics, sedative-hypnotics, and amphetamines in this class require a special prescription form:
Class B Restricted substances which easily lead to addiction like:
Class C - All prescription-only substances
Class F - Substances and package-sizes not requiring a prescription
Unclassifieds - Brands and packages not actively marketed in Norway
Medicines in Iceland are regulated by the Icelandic Medicines Control Agency.
Medicines in the Republic of Ireland are regulated according to the Misuse of Drugs Regulations 1988. Controlled drugs (CDs) are divided into five categories based on their potential for misuse and therapeutic effectiveness.
Medicines in Switzerland are regulated by Swissmedic. The country is not part of the European Union, and is regarded by many as one of the easiest places to conduct clinical trials on new drug compounds.
There are five categories from A to E to cover different types of delivery category:
Medicines in India are regulated by Central Drugs Standard Control Organization (CDSCO) Under Ministry of Health and Family Welfare. Headed by Directorate General of Health Services, CDSCO regulates pharmaceutical products through Drugs Controller General of India (DCGI) at Chair.
Drugs are classified under five headings. Under retail and distribution:
Under manufacturing practice:
Prohibited. Brands and packages not actively marketed in Sri Lanka National Dangerous Drugs Control Board
Therapeutic goods in the United States are regulated by the U.S. Food and Drug Administration (FDA), which makes some drugs available over the counter (OTC) at retail outlets and others by prescription only.
The prescription or possession of some substances is controlled or prohibited by the Controlled Substances Act, under the FDA and the Drug Enforcement Administration (DEA). Some US states apply more stringent limits on the prescription of certain controlled substances C-V and BTC (behind the counter) drugs such as pseudoephedrine.
