Exactly. The label says something along the lines of "IMP-#####" where "IMP" stands for 'investigational medicinal product' and the number is unique and tracked. Below that will be a dosage statement, a label with the patient's name and patient ID on it, and (in the UK at least) the legally-mandated words "keep out of sight and reach of children".
For orally dosed RCTs, often the pill making process is the way the blinding is done -- i.e. they're either in brightly-coloured gelcaps or a film or sugar coating. If it is a double-blind RCT it must be double blind. All of this will have been explicitly examined in the ethics statement for a trial and very, very prescriptively laid out.
That's interesting. I am only speaking from experience working in the ED as an RN and do not have any experience with studies like this that give medications that are not positively known (by myself). What you (and others say) actually does make sense. Thanks.
