==Key Stage 4==
===Meaning===
A '''placebo''' is a fake [[drug]] given to [[patient]]s during a [[Clinical Trial|clinical trial]].
===About Placebos===
: [[Placebo]]s are used to prevent [[bias]] in research caused by people expecting a potential [[medicine]] to work or not.
: '''Placebos''' are known to have a positive effect on many illnesses. To ensure that a new potential [[medicine]] is not just a [[placebo]] some of the [[patient]]s are given a [[placebo]] so the results can be compared with the potential [[medicine]]. If the results of the [[placebo]] and the potential [[medicine]] are the same, then the potential [[medicine]] had no effect.
: When administering [[placebo]] that [[patient]] is unaware whether they are being given the real potential [[medicine]] or not. This is known as a [[Blind Trial]]. Most trials of potential [[medicine]]s are [[Double Blind Trial]]s which means neither the doctor giving the potential [[medicine]] nor the [[patient]] receiving it will know if they've got the real one or not.
