A placebo is an inactive substance, typically a tablet, capsule or other dose form that does not contain an active drug ingredient.
Placebos are often used in clinical trials as an inactive control so that researchers can better evaluate the true overall effect of the experimental drug treatment under study.
Typically, an experimental drug treatment needs to be statistically more effective than the placebo to be considered as a valid drug treatment. Including a placebo group in a study is also beneficial in evaluating treatment side effects.
Placebo effect is when a placebo treatment has a positive therapeutic effect in a patient, even though the pill or treatment is not active.
