What is Pentosan Polysulfate?
Pentosan Polysulfate (PPS) is a semi-synthetic heparin-like compound derived from beechwood. It is FDA-approved (as Elmiron) for the treatment of interstitial cystitis (painful bladder syndrome). It is also approved in veterinary medicine (as Cartrophen) for osteoarthritis in dogs. It is discussed in the peptide space for its potential joint and cartilage health benefits.
Why People Talk About It
Joint and cartilage support
ModerateInterstitial cystitis (FDA-approved)
StrongAnti-inflammatory effects
ModerateHow It Works
PPS works by coating and protecting damaged tissue surfaces, reducing inflammation, and potentially supporting cartilage repair. In the bladder, it helps restore the protective lining. In joints, it may support the health of cartilage and synovial fluid.
Common Questions
Safety Information
Common Side Effects
Cautions
- • FDA warning about pigmentary maculopathy with long-term oral use
- • Regular eye exams recommended for long-term users
- • May increase bleeding risk
What We Don't Know
The mechanism of retinal toxicity is not fully understood. Risk factors for developing maculopathy are being studied.
