Abstract

A solid pharmaceutical dosage form has micro- or nanostructures impressed on the surface thereof or an interface thereof. The dosage form includes a suitable quantity and distribution of ingredients, such as one or more dyes, so as to enhance the optical contrast effect 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.
