Grundlaget for indbringelsen af sagen var, at der var afvigelser mellem de produktresuméer for Neurontin (og tilknyttede navne), der var godkendt i de forskellige EU- medlemsstater, Island og Norge, især med hensyn til indikationer, dosering, kontraindikationer, bivirkninger og de afsnit, som omhandler anbefalingerne om anvendelsen, som følge af divergerende nationale beslutninger.
The basis for referral was that there were divergences in the Summaries of Product Characteristics (SPC) of Neurontin (and associated names) approved across EU Member States, Iceland and Norway, in particular with respect to indications, posology, contra-indications, undesirable effects and sections dealing with the recommendations for use due to divergent national decisions.
