The term INERT DRUG can be summarized as a PLACEBO, which is a seven-letter word. A PLACEBO is an inactive substance or treatment that is given to a patient in order to deceive them into thinking they are receiving a real medication or treatment. Placebos are often used in clinical trials to compare the effects of a real drug or treatment to the effects of a PLACEBO. Placebos are also sometimes used in medical practice to help patients feel better without actually providing any medical benefit.
