Arthritis, encompassing osteoarthritis and rheumatoid arthritis, represents a substantial global health burden that requires advanced therapies. Flavonoids, naturally occurring compounds found widely in fruits, vegetables, and medicinal plants, show considerable potential for mitigating inflammatory processes. Specific compounds under investigation include quercetin, epigallocatechin-3-gallate (EGCG), apigenin, luteolin, fisetin, silibinin, kaempferol, naringenin, and myricetin. While clinical and experimental studies demonstrate their therapeutic efficacy and distinct mechanisms of action, poor bioavailability remains a primary barrier to their use. Nanoparticle delivery vehicles offer a way to overcome these limitations by enabling targeted delivery to inflamed joint tissues. Preclinical evidence demonstrates that nanoformulations of quercetin, EGCG, fisetin, and naringenin, as well as synergistic combinations with other compounds, could substantially improve therapeutic outcomes in arthritis management.
Arthritis affects millions worldwide, causing chronic pain and disability. Conventional treatments often carry unwanted side effects, prompting interest in natural anti-inflammatory compounds. Establishing how nanotechnology can overcome the poor absorption of plant flavonoids helps researchers design targeted treatments that deliver natural therapeutic agents directly to diseased joint tissues, improving efficacy and patient comfort.
This research informs drug developers and pharmaceutical formulators creating advanced delivery systems for inflammatory joint disorders. The primary applications involve flavonoid-based nanoparticles that enhance targeted delivery and therapeutic bioavailability for compounds such as quercetin and fisetin. Because the supported formulations are supported largely by preclinical evidence, commercial development remains at an early stage, needing extensive translational testing and clinical trials before reaching the market.

Arthritis, a global health burden comprising osteoarthritis and rheumatoid arthritis, demands advanced therapeutic approaches. In this context, flavonoids, a diverse group of naturally occurring compounds abundant in fruits, vegetables, and medicinal plants, have emerged as promising candidates for mitigating the inflammatory processes associated with arthritic conditions. This review aims, first, to provide a comprehensive exploration of the potential of flavonoids, focusing on specific compounds such as quercetin, epigallocatechin-3-gallate (EGCG), apigenin, luteolin, fisetin, silibinin, kaempferol, naringenin, and myricetin. The second section of this review delves into the anti-arthritic activities of these flavonoids, drawing insights from clinical trials and scientific studies. Each flavonoid is scrutinized individually to elucidate its mechanisms of action and therapeutic efficacy in the context of both osteoarthritis and rheumatoid arthritis. The third section of this review highlights the challenges associated with harnessing flavonoids for anti-inflammatory purposes. Bioavailability limitations pose a significant hurdle, prompting the exploration of innovative strategies such as the use of nanoparticles as delivery vehicles. In response to these challenges, the fourth section focuses on the emerging field of flavonoid-based nanoparticles. This includes detailed discussions on quercetin, EGCG, fisetin, and naringenin-based nanoparticles, highlighting formulation strategies and preclinical evidence supporting their potential in arthritis management. The targeted delivery to inflammatory sites and the exploration of synergistic combinations with other compounds are also discussed as promising avenues to enhance the therapeutic impact of flavonoids. This review consolidates current knowledge on flavonoids and their nanoformulations as potential therapeutic interventions for osteoarthritis and rheumatoid arthritis. By addressing challenges and presenting future research directions, this review aims to contribute to the advancement of innovative and effective strategies for alleviating the global burden of arthritis.
