Placebo in clinical drug trials--a multidisciplinary review.
The use of placebo in controlled clinical trials is a very difficult matter from an ethical point of view. Scientifically it offers probably the best way of obtaining fast and valid conclusions, thus promoting medical progress for the benefit of future patients. On the other hand, some patients may stand the risk of obtaining a suboptimal therapy in a placebo-controlled trial. In general, this latter aspect must be given precedence. Therefore the use of placebo control should be minimized and other control methods encouraged. However, in certain well-defined instances the use of a placebo control can be justified, provided the ethical implications can be handled.
