  • drug trials
    • drugs are first tested in a lab
      • new drugs are often developed using human cells that are grown in the lab
        • means you can measure the effect the drug has on real human cells
        • you can not create the whole organism // system
          • can not be 100% sure
        • drugs must be tested on 2 live species of mammal
          • rats & monkeys
          • this way potentially harmful substances are usually weeded out before given to human volunteers
          • mammal systems are similar to those of a human
    • drugs are then tested on humans in clinical trials

            • mammal systems are similar to those of a human
      • if the lab does not pick up anything that could limit how useful the drug can be then it will go on to be tested oon HUMAN VOLUNTEERS
        • these are called clinical trials
        • first the drug is tested for safety on healthy volunteers
          • to make sure it has no harmful side effects when the body is  working normally.
            • sick people are more vunlerable to the damage
            • if  the results on healthy volunteers are good
              • drugs are then tested on people suffering from the illness
                • tests are for safety and effectiveness
    • placebos are often used
    • blind
    • double blind
    • open label
