Placebo: a fake drug that looks like the real drug but does nothing
Volunteers who take the placebo might claim to be suffering from side effects due to anxiety during testing and noticing changes in their body
Human trials: testing for the drug is done on healthy patients to check for any side effects
Blind trials: patients do not know who is receiving the drug or the placebo
Double-blind trials: doctors and patients do not know who is getting the real drug or the placebo
It is beneficial to conduct double-blind trials to prevent bias from doctors and to avoid patients subconsciously influencing the results
When testing for a drug, scientists look for 4 major points:
Efficiency: do they work
Toxicity: are they poisonous/toxic
Dosage: how much is safe
Side effects: what are they and how severe are they
Stages of drug testing:
Drugs are tested using computer models and human cells in a lab
Animal testing: animals are given a known dosage of the drug to monitor for side effects
Volunteers and people: the drug is tested on healthy volunteers first to check safety at a low dosage and find any side effects. Then tested on people with the illness to see if they are safe and effective
Licensing: after passing all tests, drug companies get approval to produce more of the drug. This process can take 10-15 years as scientists need to look for any severe side effects
