What term refers to a medically inert substance used for comparison in trials?

• A. Placebo
• B. Indication
• C. Toxicology
• D. NDA

Answer: (A)

Placebo is the term for a medically inert substance used for comparison in trials. It looks like the active treatment and is given in the same way, but it has no therapeutic effect. Using a placebo in randomized, blinded trials helps isolate the true effect of the investigational drug by controlling for the placebo effect and for natural disease progression. This creates a neutral baseline so researchers can see how much of any observed improvement is due to the drug itself rather than expectations or other non-specific factors. Indication refers to the condition a drug is approved to treat; toxicology addresses safety and adverse effects; an NDA is the formal submission file for approval.
