Exam 1-chapter 2 Law
Pure Food and Drug Act of 1906
- Concern public health and safety - Prohibited the adulteration and misbranding of foods and drugs in interstate commerce ----In 1912, the Act was amended to prohibit false and fraudulent efficacy claims. ----The act failed to achieve its purpose. ----Difficult to enforce because it required the government to prove fraudulent intent of false statements on the label manufacturer. *****The 1906 law had not granted the FDA the authority to ban unsafe drugs---->FDA removed the elixir on a technicality. (Elixirs must contain alcohol, the elixir of sulfanilamide did not contain alcohol)
Supplemental New Drug Applications: Minor changes
.such as editorial changes in the labeling or changes in container size.
Food and Drug Administration Modernization Act of 1997 (FDAMA) Impetus
--FDA was criticized for being not efficiently administrating its statutory responsibilities and being burdensome a regulatory system for drug approval. FDAMA: - to streamline regulatory procedures to ensure the expedited availability of safe and effective drugs and devices. 1/eliminate backlogs in the approval process 2/ ensure timely review of applications.
Supplemental New Drug Applications: Production
.synthesis of drug, manufacturing process of the drug most labeling a "prior approval' supplement is required .FDA must approve the change before the manufacturer can implement it
DSHEA Criticism
-allows the marketing of unsafe dietary supplements prevents the FDA from acting aggressively enough to protect the public. --Lack of consumer information about the dangers of taking supplements with certain OTC and Rx medications. --Lack quality standards for strength and purity
Current Good Manufacturing Practice (CGMP)
..A drug is adulterated unless it is manufactured in accordance with CGMP. ..CGMP is a set of regulations that establishes the minimum requirements for the methods, facilities, or controls used to manufacture, processing, packaging, or holding of a drug product.
Adulterated Drugs
..A drug may be adulterated under the FDCA, even if it is pure, because a drug is deemed adulterated if it is: ..prepared, packed, or held in conditions where it may have been contaminated ..exposed to a container that may have been contaminated it ..or manufactured under conditions that do not conform to current Good Manufacturing Practice (CGMP) ..Apply to manufacturers, however, a pharmacy may be deemed a manufacturer if: ..it repackages or ..compounds medications for sale under certain conditions. ..A drug is adulterated if it contains an unsafe color additive, or if its strength, quality or purity differs from standards, unless stated on the label.
Imitation Drugs
..A product is an imitation if it is: ..identical in shape, size and color ..similar or virtually identical in gross appearance ..similar in effect to controlled substances
Substantial Evidence
..Adequate and well controlled investigations by experts qualified by scientific training and experience to evaluate the drug's effectiveness.
Two major offenses under FDCA
..Adulteration ..Misbranding ..Violations are Strict Liability in nature (no excuse e.g: speeding)
Supplemental New Drug Applications
..After the approval of an NDA, a manufacturer may not make any changes in the drug or it production. ..Three procedural categories: production, labeling changes, minor changes
Labeling 21 USC sec 321 (m)
..All labels and other written, printed, or graphic matter ..upon any article or any of its containers or wrappers, or ..accompanying such article
New Drug Application
..Also known as NDA ..Contains the complete evaluation of the drug's safety and efficacy. ..Hundred of thousands of pages ..FDA has 180 days to act on a completed NDA ..Delays are common ..Manufacturers rarely launch a legal challenge ..FDA proposes to disapprove an NDA, notify the applicant and provide an opportunity for hearing
Approved Drugs as "New Drugs"
..An Approved drug may become a new drug if: ..The drug contains a new substance (e.g. active ingredient, excipient, carrier or coating) ..There is a new combination of approved drugs ..The proportion of ingredients in combination is changed ..There is a new intended use for the drug ..The dosage, method, or duration of administration or application is changed.
FDA Approval Process
..Applicant must submit evidence to the FDA that shows that the drug is safe and effective. ..Conduct animal and clinical studies.
Labeling
..Broad application ..Includes the label and information accompanying the drug ..Package insert ..Accompanying = labeling ..Not accompanying = advertising
Tamper Resistant Package
..Defined as one having an indicator or barrier to entry which, if breached or missing, can reasonably be expected to provide visible evidence to consumers that tampering has occurred.
Tampering
..Defined in the act as improper interference with the product for the purpose of making objectionable or unauthorized changes.
Clinical Study Phase III
..Drug is tested for safety and efficacy in hundreds or even thousands of patients. ..Clinical settings ..Usually the study is double blinded and compared with a control group. ..Phase IV ..Postmarketing surveillance activities ..FDA required manufacturers to conduct clinical studies after the drug is approved ..The FDA may terminate testing of an IND at any time if studies show that the drug is too toxic under the agency's benefit/risk ratio.
FDA Rating and Classification System
..FDA utilizes a priority classification system that rates new drugs by chemical type and therapeutic potential. ..Determines how rapidly the drug will proceed through the NDA process.
Informed Consent
..FDCA requires investigators to obtain the informed consent of the study subject or a representative for the administration of an experimental drug. ..Informs the subject about the risks, benefits and alternative treatments. ..IRB approval of the study
Clinical Study Phase II
.Tested on a limited number of patients who actually have the disease for which the drug is an intended treatment. .Purpose is to determine the efficacy of the drug and the dosages at which efficacy occurs. .Pharmacological testing to determine the drug's safety.
Product Tampering
..Federal Anti-Tampering Act (18 USC sec 1365) ..Federal offense to tamper with consumer products ..Requires certain OTC drugs, cosmetics, and devices be manufactured with tamper resistant packaging. ..Violation may result in misbranding, adulterated, or both. ..Tylenol poisoning in 1980's Product Tampering ..Federal Anti-Tampering Act (18 USC sec 1365) ..Federal offense to tamper with consumer products ..Requires certain OTC drugs, cosmetics, and devices be manufactured with tamper resistant packaging. ..Violation may result in misbranding, adulterated, or both. ..Tylenol poisoning in 1980's

Thalidomide
1950's a popular sedative was being marketed in Europe. The FDA withheld final approval of the new drug application (NDA) pending safety information. In 1961, confirmed that thalidomide caused a birth defect, in thousand of infants. Due to the FDA refusal to allow marketing of the drug in the US, the number of birth defects in the US was low. Congress enacted the Kefauver-Harris Amendment
Federal Food, Drug, and Cosmetic Act (FDCA) 1938
21 USC 301 et seq provides for the comprehensive regulation of all drugs introduced into interstate commerce. The intent of the law is to protect consumers from adulterated or misbranded foods, drugs, cosmetics, or devices. Under the Act, no new drug may be marketed and sold unless it has been proved both safe and effective for its intended use and approved by the federal Food and Drug Administration. The FDCA with Amendments forms the nucleus of today's law. Provided that no new drug could be marketed until proved safe for use under the conditions described on the label and approved by the FDA. The law expanded the definition of misbranding and adulteration under the earlier act. Labels must contain adequate directions for use and warnings about the habit-forming properties of certain drugs. Applies to cosmetics and devices as well.

Manufacturers may make limited health claims for dietary substances that describe the relationship between a food substance and a disease. "folic acid may reduce the risk of neural tube birth defects" To make the claims, the manufacturer must receive FDA approval for the health claim as judged by the "significant scientific agreement" standard. Today, the FDA has appeared to relax its standard for evaluation, stating it would approve such claims if the scientific evidence in support of the claim outweighs the evidence against the claim.
Orphan Drug Act of 1983
Pharmaceutical manufacturers had urged Congress to recognize that the NDA process was too expensive to warrant development and marketing of drugs for diseases that affected few people.
