Describe the FDA

Overall responsibility for food safety regulation in the United States

what is phase 1 of drug trial?

Phase 1 is the initial administration of a drug to a human being. - Focuses on the pharmacology of the drug (absorption, metabolism, excretion) - Aims to establish dosage rage & route of administration - Examines safety issues and side effects - Short exposure to drugs - Small # of participants

What is Phase 3 in a drug trial?

Phase 3 trials are large, randomized control trials. Two independently performed, randomized controlled trials, unless not practical or ethical - Establish efficacy for one indication among a homogeneous group of patients compared to conventional treatment. Investigate short-term safety relative to conventional treatment

Describe the EPA

Regulation of pesticide usage and the establishment of water quality standards

what did the Food and Drug Administration Amendment Act of 2007 do?

The FDA Amendment Act provided new authority to the FDA to: 1. Require that more representative patients be included in randomized control trials 2. Require follow-up studies of drug to monitor their performance in clinical practice 3. Develop large database systems to link pharmacy records with electronic medical records to asses side effects on an on-going basis. 4. Place increased restrictions on who can prescribe a particular drug and what conditions need to be fulfilled before it can be prescribed 5. Approve and monitor drug advertising to clinicians and patients 6. Withdraw drugs from the market when serious issues of safety are raised.

What does the Foodborne Diseases Active Surveillance Network (FoodNet) do?

Works to prevent foodborne diseases. -Aims to identify and investigate foodborne disease from both outbreaks and routine exposure -Estimates the number of foodborne illnesses, monitors trends in incidence over time, attributes illnesses to specific foods and settings, and disseminates this information It is a collaboration between the CDC, FDA, and USDA.

phase 2 establishes the efficacy of the drug for a particular use. - Phase 2 trials are small, sometimes uncontrolled - establish proof of concept (does the drug actually lead to the expected and improved outcomes?)

what is phase 4 of a clinical drug trial?

phase 4 involves post-marketing surveillance and monitoring of side effects of the drug.

what needs to happen before any human beings receive a new drug?

preclinical research and testing of the drug

how are adverse effects of a drug monitored in phase 4 after FDA approval?

spontaneous reporting system: those who prescribe the drug as well as patients are encouraged to report side effects to the FDA, but they are not required to.

Who is most vulnerable to foodborne diseases?

the very young, very old, and immuno-compromised

What ways can food affect health and disease?

too little food, too much food, deficiencies of vitamins and minerals, contaminants, individual susceptibilities, foodborne communicable diseases

what are some drawbacks to phase 3 drug trial? what are some limitations to establishing safety?

trials are too small, too short, and too simple. phase 3 is very expensive, potentially harmful, and time-consuming
