 Pharnasal has been shown to be effective at reducing inflammation and promoting the repair of articular cartilage following injury or aging. It does this by stimulating the production of type 2 collagen and glycosaminoglycans, two key components of healthy cartilage. This study found that when administered interarticulately, Pharnasal was able to reduce inflammation and promote the repair of damaged cartilage. Furthermore, it was found to have the most significant effect on the repair process when combined with hyaluronic acid nanoparticles.
