 The drug Kaleorid and the placebo tablets constitute the investigational drugs in this clinical trial on humans. The drug Kaleorid is purchased and delivered by the regional pharmacy of the Capital Region of Denmark. The placebo tablets are manufactured and delivered by the regional pharmacy of the Capital Region of Denmark. The same pharmacy is responsible for the randomization of the treatment, packing of the investigational drugs and labelling of the investigational drugs. The delivered tablet containers are not labelled with content, so the treatment is planned blinded for both study participants and investigators - so intentional double-blinded.
