Answer: a placebo is a dummy pill that looks like a statin drug but has no active ingredients.
Explanation:A placebo is an inert substance which is designed to have no therapeutic value. Common placebos include inert tablets and inert injections. In the experiment to determine if statin drugs reduce the chance of having a heart attack placebo is used to create the placebo effect which is the tendency of any medication or treatment, even an inert or ineffective one, to exhibit results simply because the recipient believes that it will work.
