The Durham-Humphrey Amendment of 1951 created two classes of medications: prescription and nonprescription. This amendment updated the Food, Drug, and Cosmetic Act of 1938, which was itself a replacement for Theodore Roosevelt's Pure Food and Drug Act (1906). The 1951 amendment established a legal framework differentiating between medications that can be sold without a prescription and those that require a doctor's prescription. This law played a crucial role in modern pharmaceutical practices and promoted safer drug use, allowing the FDA to regulate and categorise drugs according to safety concerns.

What You'll Learn
The Durham-Humphrey Amendment of 1951
The law gave the U.S. Food and Drug Administration (FDA) the authority to regulate which drugs required a doctor's prescription, enhancing drug safety and appropriate usage. It ensured that potentially dangerous medications could only be accessed with medical supervision and addressed safety concerns for medications that could pose risks if used improperly. Before the amendment, there was less regulation on which medications could be sold over the counter, and manufacturers were allowed to determine the drugs' categories.
The amendment was co-sponsored by Senator (and later Vice President) Hubert H. Humphrey Jr., a pharmacist in South Dakota before his political career, and Carl Durham, a pharmacist representing North Carolina in the House of Representatives. It required any drug that is habit-forming or potentially harmful to be dispensed under the supervision of a health practitioner as a prescription drug. These prescription drugs were required to carry the statement: "Caution: Federal law prohibits dispensing without a prescription."
The Durham-Humphrey Amendment was a significant development in pharmaceutical regulation and drug safety, ensuring that patients received proper guidance when taking medications with significant effects on their health. It played a crucial role in modern pharmaceutical practices and promoted safer drug use, reflecting a commitment to safe medication and the importance of medical oversight.

Divided drugs into prescription and non-prescription
The Federal Food and Drug Administration (FDA) is the primary regulatory body for all medications in the United States. The Food, Drug, and Cosmetic Act (FDCA) of 1938 first expanded the FDA's role in medication regulation. This act, along with prior laws like the 1906 Food and Drug Act, did not initially define drug classifications.
The Durham-Humphrey Amendment of 1951 was the legislation that established two distinct classes of medications: prescription drugs and over-the-counter (OTC) drugs. This amendment was a significant milestone in drug regulation, addressing the need for medical oversight when certain drugs were deemed unsafe for self-medication.
Before this amendment, medications were not clearly classified, posing challenges to safety and medical supervision. The Durham-Humphrey Amendment required that medications potentially unsafe for self-medication be dispensed only with a physician's prescription. These prescription medications are subject to the new drug application (NDA) approval process under the Food and Drug Administration Modernization Act of 1997 (FDAMA).
The two main classes of drugs are prescription and non-prescription drugs. Prescription drugs, also known as legend drugs, require a prescription from a licensed healthcare practitioner because they are considered potentially harmful without supervision. Non-prescription drugs, commonly called OTC drugs, can be purchased without a prescription.
In addition to these two main categories, the Controlled Substances Act (CSA) further categorizes prescription medications based on their potential for abuse or addiction. This act establishes a scheduling system ranging from Schedule I to Schedule V, with Schedule I drugs having the highest potential for abuse and no acceptable medical use.

The FDA categorises and regulates drugs
The US Food and Drug Administration (FDA) is responsible for regulating and approving drugs to ensure they are safe, effective, and of high quality. The FDA was founded as a consequence of Theodore Roosevelt's Pure Food and Drug Act (1906), which prohibited misleading and fraudulent labelling of foods and drugs. The Food, Drug, and Cosmetic Act of 1938 replaced this legislation, and in 1951, the Durham-Humphrey Amendment further updated it by establishing two classes of medication: prescription and non-prescription.
The FDA categorises drugs as prescription or non-prescription medications. Prescription medications are drugs that may be harmful or create poor habits if used without professional supervision. Antibiotics and certain pain relievers are examples of prescription drugs. Non-prescription drugs, on the other hand, can be safely used without medical guidance. Ibuprofen, for example, is a non-prescription drug. Before the Durham-Humphrey Amendment, manufacturers determined the classification of drugs. Now, if manufacturers disagree with the FDA's assigned classification, they may submit a supplemental application, petition, or undergo a review process.
The FDA does not conduct clinical trials or develop new therapies. Instead, it establishes rules and regulations to ensure the safety of clinical trials and the volunteers involved. Once a drug maker has conducted clinical trials and gathered sufficient data to demonstrate safety and efficacy, they can submit a New Drug Application for FDA approval. The FDA also approves generic, biosimilar, and over-the-counter drugs.
In addition to its approval process, the FDA continues to monitor approved drugs for safety and quality. The FDA does not, however, control the cost of drugs or intervene in interactions between patients and healthcare providers. The FDA also does not regulate the distribution and sale of drugs, as this falls under the jurisdiction of state and local governments. Nevertheless, the FDA plays a crucial role in promoting safe medication practices and influencing how medications are managed in healthcare.

Enhances drug safety and appropriate usage
The Durham-Humphrey Amendment of 1951 created two classes of medications: prescription and nonprescription. This law enhanced drug safety and appropriate usage by allowing the FDA to regulate which drugs required a doctor's prescription. It established a legal framework differentiating between medications that could be safely used without medical guidance (non-prescription) and those that were unsafe to use without a healthcare provider's supervision (prescription).
Prior to the amendment, there was less regulation regarding which medications could be sold over the counter. Manufacturers previously determined the categorization of drugs. The new law ensured that potentially dangerous medications could only be accessed with medical supervision, thereby reducing the risks associated with improper medication usage.
The creation of two classes of medications addressed safety concerns for drugs that could pose risks if used improperly. It ensured that patients received proper guidance when taking medications that could significantly impact their health. For example, antibiotics and certain pain relievers are prescription drugs requiring monitoring by healthcare professionals, while common pain relievers like ibuprofen are nonprescription and can be purchased over the counter.
The classification system reflects a commitment to safe medication practices and the importance of medical oversight, which continues to influence how medications are managed in healthcare today. This law played a pivotal role in modern pharmaceutical practices, promoting safer drug use. It is a recognized part of U.S. drug law and is routinely cited in discussions about pharmaceutical regulation. Additionally, the FDA also ensures child safety by enforcing laws that require child-resistant packaging for medications. Furthermore, studies have shown that inappropriate prescribing is common in older adults with multiple comorbidities and polypharmacy, leading to adverse health outcomes. To address this issue, interventions such as OPERAM aim to optimize pharmacotherapy and enhance patient outcomes by reducing inappropriate prescribing.

Influenced modern pharmaceutical practices
The Federal Food, Drug, and Cosmetic Act (FDCA) of 1938 categorised medications into two classes: over-the-counter (OTC) and prescription medications. This law has influenced modern pharmaceutical practices by providing a framework for regulating the safety and efficacy of drugs. It also ensures that patients and practitioners are aware of the ingredients and potential side effects of medications.
The FDCA established the Food and Drug Administration (FDA) as the main regulatory body for medications in the United States. The FDA's role is to protect the public health by ensuring the safety and efficacy of drugs, medical devices, and other products such as tobacco and vaccines. The FDA also regulates the marketing and distribution of pharmaceuticals, requiring wholesale retailers to obtain special licenses and allowing samples to be provided only upon request by a licensed prescriber.
The FDCA has been amended several times to meet changing needs and to further regulate medicine and pharmacy practices. For example, the Durham-Humphrey Amendment of 1951 distinguished between OTC and prescription drugs, requiring the latter to be dispensed only with a valid prescription from a licensed healthcare professional. The Kefauver-Harris Amendment, passed in response to the discovery of Thalidomide teratogenicity, provides the modern framework for pharmaceutical approval, including Phase 2 and Phase 3 trials.
Another example is the Orphan Drug Act, which incentivises the development of new medications for rare diseases with limited treatment options. The Medical Devices Amendment Act differentiated medical devices from pharmaceuticals and classified them based on patient risk, providing guidelines for approval and distribution. The Comprehensive Drug Abuse Prevention and Control Act, passed under Nixon's war on drugs, created the Drug Enforcement Administration (DEA) and regulated drug classification, procurement, distribution, prescription, and registration.
Overall, the FDCA and its amendments have had a significant influence on modern pharmaceutical practices by establishing a comprehensive framework for regulating medications and ensuring their safety and efficacy. These laws have also addressed issues such as quack medicine, faulty medical devices, and the abuse and dependency potential of drugs.
