I believe there is a certain extent to where the placebo controlled trails are ethical. They are a “sugar pill” that sometimes can convince the human body to fix the problem itself but some diseases do not just fix itself. Sometimes clinical trials that require a placebo means that the patient does not get all the approved treatment that they could have received if they didn’t do the clinical trial. Depriving the patient of approved treatment that could help them is unethical because the patient wants some type of treatment given to them during the clinical trial. The patient looks for clinical trials because they want another option to help fix their disease and usually it’s their last chance so not giving them the treatment would mean they wouldn’t be getting better. I also do believe that placebo controlled trials are necessary because they determine whether or not the clinical trial works or if it’s just the patient thinking they’re getting better and feeling better. The advantages are that the patient has a better chance of getting better if they get the actual treatment but the disadvantage is if they get the placebo, they might not get better.
