The Landscape of Products for Diabetic Peripheral Neuropathy: A Scientific and Patent Systematic Review.

Background: Diabetic peripheral neuropathy (DPN) is a complication of diabetes that occurs in 40 - 60 million individuals worldwide and is associated with other chronic diseases. However, there are no review studies that present the state-of- the- art and technologies developed to circumvent this important health problem.

Material and methods: This review was conducted based on scientific papers and patents. The papers were retrieved from Lilacs, PubMed, and Web of Science databases, and the patents from INPI, ESPACENET, WIPO, and GOOGLE PATENTS. Thus, a sample consisting of 14 scientific articles and 667 patents was analyzed.

Results: From the analysis of the data, we drew an overview of the development of biomedical technologies for DPN and detected the pioneering spirit of China, the USA, and Japan in the area, with a focus on the treatment of DPN. Based on this, we carried out a SWOT analysis to help direct future efforts in the area, which should focus primarily on developing technologies for prevention, early diagnosis, and, above all, cure of the disease to reduce the important impact of this disease in various sectors of society.

Conclusion: This study finds a concentration of diabetic peripheral neuropathy products, especially therapeutic drugs, in high-income countries. It highlights the need for global collaboration and strategic focus on therapeutic adherence and preventive strategies to effectively manage DPN.
