A solid pharmaceutical dosage form [19] has micro- or nanostructures [10a, lOb, lOc, lOd] impressed on the surface thereof or an interface thereof. The dosage form [19] includes a suitable quantity and distribution of ingredients, such as one or more dyes, so as to enhance the optical contrast effect, C, caused by the micro- or nanostructures so that the micro- or nanostructures are observable by the human eye and thereby able to provide anti- counterfeiting characteristics to the dosage form.

L'invention concerne une forme posologique pharmaceutique [19] qui présente des micro- ou nanostructures [10a, 10b, 10c, 10d] imprimées à sa surface ou sur une de ses interfaces. La forme posologique [19] contient une quantité appropriée et une distribution appropriée d'ingrédients, tels qu'un ou plusieurs colorants, pour optimiser l'effet de contraste optique C causé par les micro- ou nanostructures, afin que les micro- ou nanostructures soient visibles par l'oeil humain et afin de fournir ainsi des caractéristiques anti-contrefaçon à la forme posologique.
