Understanding Clinical Trials: Testing Medicines for Safety and Effectiveness

Clinical trials are essential tests involving volunteers to assess the safety and effectiveness of new medicines before public release. These trials utilize placebos as controls, allowing researchers to compare responses. Key components include sample size, which impacts the reliability of results, and simulations that replicate experimental conditions. Data collected from these trials helps draw evidence-based conclusions about new treatments. A well-designed trial requires a large sample size and effective data graphing to identify patterns in human responses, which can vary widely.

Presentation Transcript

  1. Activity #3 Testing Medicines: A Clinical Trial

  2. Key Words • Clinical Trial – a test performed on volunteers, typically to test medicines, before the products are made available to the public • Control – a standard used for comparison that is not changed throughout the experiment • Placebo – a control that simulates a medicine but doesn’t have the active ingredient

  3. Key Words • Sample Size – the amount of people or thing being tested • Simulation – an experience that is meant to mimic, or be like, another experiment • Trade-Off – an exchange of one thing in return for another

  4. Purpose of Clinical Trials • Include a placebo group. • Used to test safety and effectiveness of medicines. • Evidence gathered from these trials can be used to make conclusions.

  5. Summary • Human responses vary. • One part of a good scientific design is a large sample size. • Graphing data can reveal patterns about the experiment.
