As a result, the overall share of generics in pharmaceutical use in France remained around one third in 2015, despite a substitution rate close to 80% within authorised classes of drugs (Panel B). Adopting a broader list of drugs for which generics may substitute and, more generally, allowing greater use of generics, would be helpful (Cour des comptes, 2014c). Indeed, the authorities plan a limited expansion of the list of dings that generics may substitute (ministere des Affaires sociales, de la Sante et des Droits des femmes, 2015). Share in the reimbursed pharmaceutical market.
