Core Viewpoint - The article discusses the rise of monoclonal antibody (mAb) injections, also known as "biological agents," in the treatment of chronic diseases, highlighting the issues surrounding their online sale and the importance of proper medical supervision for their use [1][11]. Group 1: Market Trends - Monoclonal antibodies are becoming mainstream treatments for chronic diseases such as autoimmune disorders and skin diseases due to the expansion of indications and domestic production [1][11]. - The demand for effective treatments in rheumatology and dermatology is increasing, with mAbs being recognized for their significant therapeutic effects [11][12]. Group 2: Online Sales and Regulations - Some pharmaceutical e-commerce platforms are attempting to sell injectable mAbs online, despite regulations prohibiting the online retail of such prescription drugs [2][6]. - Many sellers use terms like "appointment for medication" and "contact customer service after payment" to imply that they are not directly selling the drugs online, which raises compliance concerns [3][6]. Group 3: Safety and Usage - The use of biological agents requires strict adherence to indications and contraindications, necessitating a doctor's assessment and prescription before use [1][5][8]. - Proper cold chain logistics are essential for the safe transport of these drugs, but safety also depends on medical supervision and monitoring during treatment [8][10]. Group 4: Efficacy and Limitations - Biological agents have shown remarkable efficacy in treating various autoimmune diseases, but they are not a cure and require ongoing management [12][13]. - The high cost of mAbs, often thousands of yuan per injection, poses a barrier to access, and their effectiveness can vary among patients [13].
