Pentosan Polysulfate looks promising for knee joint pain – first look

gov/34225678/. The authors ran a 12‑week, double‑blind, placebo‑controlled in 80 patients with knee OA. They used 100 mg oral PPS three times daily, the same dose that the NHS uses for interstitial cystitis.

Patients on PPS reported a 30‑per‑cent drop in pain scores, and the MRI data showed a modest rise in cartilage thickness compared with baseline. Notably, there were no serious adverse events, except two mild GI upset cases. For me, the idea of a drug that can actually help the cartilage, not just mask pain, feels like a step in the right direction.

I’m still sceptical about long‑term safety, especially the maculopathy risk that shows up after years of high‑dose use. How long do you think you can stay on PPS before the eye risk starts creeping in?
