Inactive substance resembling a medication?

Inactive substance resembling a medication?

• A. Enteric-coated
• B. Gtt.
• C. Suspension
• D. Placebo

Answer: (D)

The main idea is an inert substance that mimics a real medication in appearance and administration. A placebo is designed to look like the active drug but contains no pharmacologically active ingredient, which makes it ideal for use as a control to measure the true effect of the drug versus expectations or placebo effect. Why the other terms don’t fit as well: an enteric-coated form is a real drug with a coating that delays release in the stomach, so it’s not inert. Gtt. refers to drops, a dosage form that may contain active medication or could just be a vehicle, but the term itself doesn’t denote an inert substance. A suspension is a liquid containing dispersed drug particles, again typically containing an active ingredient, not an inert mimic. So the option that describes an inactive substance resembling a medication is the placebo.
