Study Notes
Drug Design, Testing, Manufacturing, and Marketing
- Drug discovery is a time-consuming and expensive process, evaluating thousands of chemicals before FDA approval.
- Drug discovery involves identifying candidates, synthesis, characterization, screening, and assays for therapeutic efficacy. This process flows through different stages.
- Research & Early Development: Understanding the disease mechanism and finding new chemicals/molecules effective against biological targets.
- Preclinical Research: Determining a product’s safety profile through testing on animals for pharmacodynamics, pharmacokinetics, ADME (absorption, distribution, metabolism, excretion), and toxicity.
- Chemical & Pharmaceutical Development: Designing the quality product and its manufacturing process meeting all specifications and controls.
- Clinical Research (4 Phases): Gathering safety and efficacy data for new drugs. These trials only occur after adequate non-clinical safety information and health authority approval have been granted. The drug is submitted for regulatory approval after the trials.
- Chemical & Pharmaceutical Production: Building a full-scale manufacturing plant based on the scientific understanding from the earlier stages.
- In vitro testing: Laboratory testing in glass tubes and Petri dishes.
- In vivo testing: Testing on living humans or animals.
- Placebo: Used in double-blind tests and is a substance appearing to be a medical treatment, but is not.
- Isomer: Compounds with the same formula but a different arrangement of atoms and thus different properties.
- Drug Manufacturing: FDA monitors both generic and trade name drug quality and consistency across all drug companies. Generic and trade names of drugs must contain the same exact active ingredients. Variations among manufacturers for inert ingredients, preservatives, antioxidants, and buffers are allowed. A manufacturer cannot change ingredients, manufacturing processes, labeling, packaging, and dosage once approved by the FDA. Packaging includes tamper-evident, child-resistant, amber glass, blister packs, and sealed containers.
- Drug Marketing: Over-the-counter (OTC) drug advertising is regulated by the FTC. Prescription drug advertising is regulated by the FDA based on the Federal Food, Drug, and Cosmetic Act. Drug companies have used doctor visits, samples, and promotional tools in the past. Direct-to-consumer marketing is growing.
- Drug Patents: Trade names are registered with the U.S. Patent Office as trademarks. The patent protects the drug company for 17 years, preventing other drug companies from producing an identical drug. Once the patent expires, any company can manufacture the drug under either the original generic name or a new trade name. An original drug's trade name can only be used by the original company.
- National Drug Code (NDC): A unique identifier for drugs, given in three segments. The first segment represents the drug company determined by the FDA, the second is the drug's specific strength/dose, and the third is the package code.
- Phases 0-4 of human testing:
- Phase 0: Small-scale research to test if the drug behaves as expected.
- Phase 1: Dosage testing on few patients to determine the best dose and side effects.
- Phase 2: Examining the safety profile in a larger group alongside the treatment effectiveness.
- Phase 3: Comparing the new treatment with the standard treatment.
- Phase 4: Monitoring the drug’s safety and effectiveness after licensed.
Reasons for Pulling a Drug From the Market
- Risk of health problems (studies after market show unexpected links to complications)
- Drug interactions (mixing drugs or food can cause unforeseen issues)
- Manufacturing/packaging errors (contamination or faulty packaging processes).
