27This requirement is intended to fulfil the objectives which Directive 2001/83 seeks to attain, namely, first, the elimination of hindrances to trade in medicinal products between the Member States and, second, the protection of public health (see Case C-84/06Antroposana and Others [2007] ECR I-7609, paragraph 36).
