New drugs are first tested for
safety and effectiveness using human cells grown in the laboratory and animals.
Human trials may then be
carried out on healthy volunteers to test for safety and on people with the
illness to test for safety and effectiveness.
Make sure that you can
describe and explain the use of 'blind' or 'double-blind' human trials in the
testing of a new medical treatment. |
