China to Renew Medical Sodium Hyaluronate\’s Administrative Classifications

On May 20, China National Medical Products Administration (NMPA) released the revised draft of the Announcement on the Administrative Classifications of Sodium Hyaluronate Products for Medical Use (hereafter referred to as the draft and the Announcement, respectively) for public comments. The draft renews the classification system of medical sodium hyaluronate products according to their intended uses and mechanisms of action.¹

Current Classifications of Medical Sodium Hyaluronate

The current classifications are based on the 2009 version of the Announcement. Medical sodium hyaluronate products are generally classified into two categories: administered as drugs and as medical devices.²

Medical Sodium Hyaluronate

Classification

Products that have clear pharmacological effects, e.g., treating arthritis, dry eyes, skin ulcer, etc.

Drug

Adjuvant products in eye surgery;

Anti-adhesion products in surgery;

Tissue filler and tissue volume-augmenting products, etc.

Medical Device

Classifications for Consultation

If following the current classification rules, some sodium hyaluronate products are difficult to classify because in terms of functions, they are on the boundaries between drugs, medical devices, and cosmetics. To address the difficulty, the draft defines the classifications of such \”boundary\” products, drug-device combination products, and relevant medical devices:

1. Products for treating arthritis or dry eyes should be administered as drugs;

2. Products should be administered as medical devices if they meet the following conditions and contain no medical ingredients that have pharmacological, metabolic, or immune functions. Such products\’ administrative classifications should be no lower than Class II.
