Chondroitin Sulfate Capsules are useful in two ways: First, the drug contains glucosamine sulfate, which inhibits cartilage degeneration and is effective in relieving pain and unfavorable activity symptoms in osteoarthritis of the knee, chondromalacia patellae, and arthritis of other joints, and can effectively prevent and treat cartilage degeneration. Secondly, this drug contains chondroitin, a mucopolysaccharide extracted from animal cartilage, which can effectively promote the metabolism of cells in the joints so that local inflammation and metabolites such as lactic acid do not accumulate and can be metabolized in a timely and effective manner, reducing the peripheral nerve irritation around the joints and therefore relieving the symptoms of pain and unfavorable activity. Therefore, amylose sulfate chondroitin capsule is a good treatment for neck, shoulder, lumbar and leg pain, pain in the joints and unfavorable movement symptoms.
