[Analysis of regulatory status changes of drugs in France: 2010-2019]

The existence of borderline products between the status of a medicinal product and other less regulated products allows some products to have different statuses or even to change from one status to another. In order to quantify these changes, a review of medicines that have changed from drug status to other statuses (medical device, cosmetic product or food supplement) in France between 2010 and 2019 was performed.

The lists of medicinal products with archived or revoked marketing authorization (MA) from the French National Authority's Register of Medicinal Products were analyzed in order to identify the medicinal products withdrawn from the market between January 1, 2010 and September 30, 2019 that could be considered as products with a "potential for status change". Then, we searched on the official websites of the MA holders and other firms, for a possible return to the market with a different status, marketed by the same firm (self-change of status) or a different firm (hetero-change of status).

Out of a list of 206 drugs identified as "with potential for status change", we detected a total of 101 status changes, including 36 auto-changes and 65 hetero-changes. These changes mainly concern vitamin or herbal drugs later marketed as food supplements (30 cases of auto-changes and 60 cases of hetero-changes). There are also 6 cases of switching to cosmetic product and 5 cases of switching to medical device.

The existence of no clear distinction between the different statuses of health products facilitates their status changes. The increasing shift from "medicines" to less regulated products, the trivialization of their use by the public and their increasing consumption make them a fundamental issue of social pharmacology, requiring to raise the awareness of consumers and health professionals.
