    Lec 30 - Esomeprazole as an Example of Drug Testing and Usage

    "Lec 30 - Esomeprazole as an Example of Drug Testing and Usage" Freshman Organic Chemistry (CHEM 125) The chemical mode of action of omeprazole is expected to be insensitive to its stereochemistry, making clinical trials of the proposed virtues of a chiral switch crucial. Design of the clinical trials is discussed in the context of marketing. Otolaryngologist Dr. Dianne Duffey provides a clinician's perspective on the testing and marketing of pharmaceuticals, on the FDA approval process, on clinical trial system, on off-label uses, and on individual and institutional responsibility for evaluating pharmaceuticals. 00:00 - Chapter 1. Introduction: The Chemical Properties and Reactivity of Prilosec 06:58 - Chapter 2. The Economics of Clinical Trials 19:57 - Chapter 3. Duffey: How Do I Know that the Drug is Effective? 30:26 - Chapter 4. The Phases of Clinical Trials, Results for Esomeprazole and Omeprazole, and Off-Label Use 42:01 - Chapter 5. Pharmaceutical Marketing Mentality and Q&A Complete course materials are available at the Open Yale Courses website: http://open.yale.edu/courses This course was recorded in Fall 2008.
