<p>A solid pharmaceutical dosage form [19] has micro- or nanostructures [10a, 10b, 10c, 1Od] 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.</p> |
