sodium hyaluronate (Yooyoung Pharmaceutical)

HyaleXo is a high molecular weight sodium hyaluronate (hyaluronic acid) viscosupplement developed by Yooyoung Pharmaceutical for the symptomatic relief of pain in patients with knee osteoarthritis or degenerative joint diseases. As a major constituent of synovial fluid, hyaluronic acid provides essential viscosity and elasticity to the joint, facilitating lubrication and shock absorption. In degenerative joint conditions, the concentration and molecular weight of endogenous hyaluronic acid are typically reduced, leading to pain and decreased mobility. HyaleXo is administered via intra-articular injection to restore the viscoelastic properties of the synovial fluid, thereby attenuating pain and improving joint function. It is often regulated as a medical device (viscosupplement) in various jurisdictions.
