  • Drugs are tested in the lab to find if they are toxin
  • They are then trialled on human volunteers to discover any side effects and what the highest safe dose is
  • They are then tested on people who have the illness it is meant to treat to find out if it makes people feel better

Thalidmide is a drug that was developed asa sleeping pill. it was also found to relieve morning sickness in pregnant women.it had not been tested for use in pregnant women. unfortunatly,many babies born to mothers who took the drug were born severe limb abnormalities. the drug was then banned.it is now used to treat leprosy.
