2. Our Hyaluronic Acid Products

As pioneering pharmaceuticals, ARTZ and OPEGAN are products that take advantage of the unique properties of hyaluronic acid.

ARTZ^® 25 mg / ARTZ Dispo^® 25 mg - Intra-articular injections for improving joint functions

ARTZ 25 mg is the world's first joint function improving agent whose main ingredient is hyaluronic acid. It was developed based on the knowledge that hyaluronic acid is an important component of joint fluid. By being directly injected into the joint, the drug can help improve osteoarthritis, periarthritis of the shoulder^*1, and knee pain from chronic rheumatoid arthritis^*2, which are diseases common among seniors.

ARTZ Dispo 25 mg is a pre-filled syringe type product, eliminating the time required to withdraw the drug solution (hyaluronic acid) from the ampule.

ARTZ has obtained regulatory approval in 21 countries. With more than 200 million injections having already been administered internationally, it is earning trust for its ability to improve “Quality of Life” for people all over the world.

OPEGAN, OPEGAN Hi - Ophthalmic Surgical Aids

The ophthalmic surgical aid OPEGAN was the first domestically produced hyaluronic acid formulation. High-viscosity hyaluronic acid is used to facilitate cataract surgery by protecting the corneal endothelium and retaining the intraocular space.

OPEGAN Hi achieves a higher level of viscoelasticity by increasing the molecular weight of hyaluronic acid. Since its release, it has contributed to the increased number of cataract surgery by simplifying the procedure.
