  1. Effect of colour of drugs : systematic review of perceived effect of drugs and of their effectiveness.

    Article - En anglais

    Objectives-To assess the impact of the colour of a drug's formulation on its perceived effect and its effectiveness and to examine whether antidepressant drugs available in the Netherlands are different in colour from hypnotic, sedative, and anxiolytic drugs.

    Design-Systematic review of 12 published studies

    Six studies examined the perceived action of different coloured drugs and six the influence of the colour of a drug on its effectiveness.

    The colours of samples of 49 drugs affecting the central nervous system were assessed using a colour atlas.

    Main outcome measures-Perceived stimulant action versus perceived depressant action of colour of drugs ; the trials that assessed the effect of drugs in different colours were done in patients with different diseases and had different outcome measures.


    The studies on perceived action of coloured drugs showed that red, yellow, and orange are associated with a stimulant effect, while blue and green are related to a tranquillising effect.

    The trials that assessed the impact of the colour of drugs on their effectiveness showed inconsistent differences between colours.

    The quality of the methods of these trials was variable.
