Aminosugars are mainly used to treat and prevent osteoarthritis in various parts of the body, such as the more common arthritis of the knee, hip, wrist and ankle joints. Aminosugars include glucosamine sulfate and glucosamine hydrochloride, both of which have similar effects and are mainly used for the prevention and treatment of arthritis. The mechanism of action of glucosamine is to stimulate the synthesis of cartilage cells in the joint by acting on the joint, and also to inhibit the destruction of joint cartilage, which can reduce the damage to joint cartilage cells by certain drugs and specific adverse triggers. By nourishing the cartilage surface and promoting synthesis, it ultimately prevents and treats osteoarthritis.
