Hi Scott,
>It would be preferable to use an active placebo.....
.....but what if the active drug produced a higher incidence of side effects than the active placebo. Due to the high incidence of side effects, people given the active drug may view it as being a 'powerful' drug, this may increase the placebo effect, thus suggesting that an (ineffective) drug was more effective than placebo.
>One might consider withdrawal of the active compound for two weeks after a response, and then rechallenge if a relapse ensues.
What about withdrawal symptoms?
Kind regards
