Indications

Pentosan Polysulfate Sodium is used to relieve bladder pain or discomfort that comes with interstitial cystitis.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Pentosan polysulfate is a polymer of xylose hydrogen sulfate, with two sulfate groups on each carbohydrate monomer. It binds Fibroblast growth factors (FGFs) and other heparin-binding growth factors, and it has also been shown to interact with the heparin-binding site of FGFR-1. In laboratory work, pentosan polysulfate inhibits the growth of SW13 adrenocortical cells transfected with FGF-4. It also inhibits the tumorigenicity of MCF-7 breast carcinoma cells transfected with FGF-1 or FGF-4.

Pregnancy & Breastfeeding

Pregnancy

Pentosan Polysulfate Sodium has been tested in animals. Mice and rats were given 15 mg/kg intravenously every day, and rabbits were given 7.5 mg/kg. Compared with the daily oral dose in humans, and adjusted for body surface area, these doses were 0.42 and 0.14 times as high. The studies showed no sign of reduced fertility or harm to the fetus.

In a separate laboratory test, cultured mouse embryos were bathed directly in pentosan polysulfate sodium (PPS) at a concentration of 1 mg/mL. This may cause reversible limb bud abnormalities.

No adequate, well-controlled studies have been done in pregnant women. Animal studies don't always predict how humans will respond, so the medicine should be used in pregnancy only if clearly needed.

Nursing mothers

It isn't known whether this medicine passes into human milk. Many drugs do, so caution is needed when Pentosan Polysulfate Sodium is given to a breastfeeding woman.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: The recommended dose of Pentosan Polysulfate Sodium is 300 mg a day, taken as one 100 mg capsule by mouth three times daily. Swallow the capsules with water, at least 1 hour before meals or 2 hours after meals. Patients taking Pentosan Polysulfate Sodium should be reassessed after 3 months. If there's no improvement and no limiting adverse events, the treatment may go on for another 3 months. For patients whose pain hasn't improved by 6 months, the clinical value and risks of carrying on with treatment are not known. Pediatric Use: Safety and effectiveness in patients below the age of 16 years have not been established.
