Pentosan Polysulfate Protocol Guide
Pentosan Polysulfate Sodium (PPS) is a semi-synthetic glycosaminoglycan derived from beechwood hemicellulose. It is FDA-approved for interstitial cystitis (Elmiron) and studied for osteoarthritis, joint repair, and cartilage protection. It exhibits anti-inflammatory, fibrinolytic, and glycosaminoglycan-replenishing properties.
Protocol Overview
- Compound
- Pentosan Polysulfate (Semi-Synthetic Heparinoid (FDA-Approved for IC))
- Category
- Glycosaminoglycan Compound
- Vial Size
- 250mg (250,000mcg)
- Reconstitution
- N/A - Injectable Solution bacteriostatic water
- Route
- Subcutaneous injection
- Frequency
- 2 days/week
Reconstitution Instructions
Pentosan Polysulfate is supplied as a ready-to-use injectable solution. No reconstitution with bacteriostatic water is required. Administer via intramuscular injection using sterile technique.
Materials Needed
- 250mg Pentosan Polysulfate 250mg vial (lyophilized powder)
- N/A - Injectable Solution bacteriostatic water (sterile, preserved with 0.9% benzyl alcohol)
- Sterile syringe and needle (18-22 gauge for drawing)
- Alcohol swabs
- Clean workspace
Step-by-Step Process
- Preparation: Allow the Pentosan Polysulfate 250mg vial and bacteriostatic water to reach room temperature. Wipe the rubber stoppers of both vials with an alcohol swab.
- Draw the Water: Using a sterile syringe, draw up exactly N/A - Injectable Solution of bacteriostatic water. Expel any air bubbles.
- Inject into Vial: Insert the needle through the rubber stopper at a slight angle, aiming toward the glass wall. Slowly inject the water down the side of the vial to avoid foaming.
- Mix Gently: Remove the needle. Gently swirl or roll the vial between your hands. Do not shake vigorously.
- Check for Clarity: The solution should be clear once fully reconstituted. Do not use if cloudy.
