What is the primary ethical concern with using placebos in clinical trials?

• A. The high cost of alternative treatments
• B. The potential to withhold effective treatment from participants
• C. The possibility of participant bias
• D. The requirement for extensive pilot studies

Answer: (B)

The primary ethical concern with using placebos in clinical trials is the potential to withhold effective treatment from participants. In clinical research, the use of a placebo can be justified when no standard treatment exists, but when effective treatments are available, using a placebo raises ethical dilemmas. Researchers must consider the welfare of participants, as withholding effective treatment may expose them to unnecessary harm or prolong suffering unnecessarily. This concern is especially pertinent in trials for serious or life-threatening conditions, where the participants might suffer significantly by not receiving the standard treatment they need. Thus, ensuring that participants are not deprived of effective care is central to ethical research practices, making this concern highly significant in the context of clinical trials.
