🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines glucosamine and chondroitin, which work together to support joint health. Glucosamine is a natural compound that provides raw material for the synthesis of glycosaminoglycans and proteoglycans, which are essential components of cartilage matrix. Chondroitin sulfate is a glycosaminoglycan that helps retain water in the cartilage, providing shock-absorbing properties and inhibiting enzymes that break down cartilage. Together, they may reduce inflammation, stimulate cartilage repair, and slow cartilage degradation. However, the exact mechanism by which they relieve osteoarthritis symptoms is not fully understood.
