Chondroitin tablets are a kind of health care product, not a regular drug. The main function of chondroitin tablets is to prevent and treat arthritis in patients, and the principle of treating arthritis is to promote the metabolism of cartilage and the formation of cartilage surface so as to play a role in protecting the bone tissue, which can play a role in preventing arthritis. In addition, chondroitin has a protective effect on the heart, and when applied together with lipid-lowering drugs, it can promote the discharge of blood lipids and prevent high blood lipids. Chondroitin has a pain-relieving effect when applied together with painkillers after abdominal surgery, which can minimize the pain of abdominal surgery patients. Chondroitin also has the effect of promoting the absorption of fluid in the knee joints, which is, on the whole, a kind of health care product rather than a medicine.
