WechselwirkungenThe effect of pentosan polysulfate sodium on warfarin pharmacokinetics and pharmacodynamics was investigated in healthy subjects. Warfarin was titrated to an international normalized ratio between 1.4 and 1.8. Subjects continued their titrated dose of warfarin and received pentosan polysulfate sodium 100 mg or placebo every 8 hours for 7 days. The Cmax of R- and S-warfarin was approximately 840 to 890 ng/mL and 680 to 730 ng/mL, respectively, and was similar in the absence and presence of pentosan polysulfate sodium. The half-life for R- and S-warfarin was 52 to 56 hours and 36 to 40 hours, respectively. Prothrombin time, partial thromboplastin time, and the international normalized ratio for warfarin + placebo and warfarin + pentosan polysulfate sodium were comparable. The AUC(INR) indicated no treatment effect (P = .772)however, there was a period effect. Analysis of variance for the treatments by period indicated no treatment effect (P > .1). Adverse events were mild and included headache, epistaxis, and rash. Most adverse events were unrelated to treatment and were seen during warfarin titration. Pentosan polysulfate sodium did not affect warfarin pharmacokinetics or pharmacodynamics.The risk of hemorrhage may be increased when pentosan polysulfate sodium is used concurrently with drugs that affect hemostasis (e.g., oral anticoagulants, heparin, nonsteroidal anti-inflammatory agents (NSAIAs), thrombolytic agents [e.g., alteplase]). Patients receiving such concomitant therapy should be monitored for hemorrhage.
ToxizitätsübersichtIDENTIFICATION AND USE: Elmiron (Pentosan polysulfate) is a white powder. Elmiron is a weak anticoagulant (1/15 the activity of heparin). it is indicated for the relief of bladder pain or discomfort associated with interstitial cystitis. It is also used in veterinary medicine. HUMAN STUDIES: Elmiron, a highly sulfated, semisynthetic pentose polysaccharide with properties similar to heparin, is used for the treatment of interstitial cystitis. Overdose of Elmiron has not been reported. Based upon the pharmacodynamics of the drug, toxicity is likely to be reflected as anticoagulation, bleeding, thrombocytopenia, liver function abnormalities, and gastric distress. A case of severe thrombocytopenia and ischemic stroke following Elmiron treatment has been reported. The development of thrombocytopenia was reported in 25 patients receiving either heparin or Elmiron over a 7 month period. Based on platelet aggregation studies it was suggested that an immune allergic reaction to the anticoagulants occurred. ANIMAL STUDIES: Elmiron was orally administered once daily via gavage, 5 days per week, for up to 2 years. The dosages administered to mice were 56, 168 or 504 mg/kg. The dosages administered to rats were 14, 42, or 126 mg/kg for males, and 28, 84, or 252 mg/kg for females. Elmiron was carcinogenic to mice but not rats. Increased incidences of liver hemangiosarcoma, hepatocellular neoplasms (predominantly adenomas), and malignant lymphomas revealed carcinogenic activity of Elmiron in female mice. Reproduction studies have been performed in mice and rats with intravenous daily doses of 15 mg/kg, and in rabbits with 7.5 mg/kg. These studies did not reveal evidence of impaired fertility or harm to the fetus from Elmiron. Elmiron sodium was not clastogenic or mutagenic when tested in the mouse micronucleus test or the Ames test (Salmonella typhimurium).

Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ Overdose has not been reported. Based upon the pharmacodynamics of the drug, toxicity is likely to be reflected as anticoagulation, bleeding, thrombocytopenia, liver function abnormalities, and gastric distress./CASE REPORTS/ Pentosan polysulfate sodium (ElmironAlza Pharmaceuticals, Mountain View, Calif) is an oral preparation of pentosan polysulfate used in the symptomatic management of interstitial cystitis. While pentosan polysulfate has a known heparin-like effect in its parenteral form, there have been no previous reports of coagulopathy with oral use. We present an interesting case of inadvertent systemic anticoagulation resulting in serious bleeding complications in a young woman taking oral pentosan polysulfate for interstitial cystitis./CASE REPORTS/ We report a patient who developed severe thrombocytopenia and ischemic stroke following pentosan polysulfate treatment. An ELISA test employed in type-II heparin-induced thrombocytopenia was highly positive. To our knowledge, this is the first case in which this test has been performed in a pentosan polysulfate-induced thrombocytopenia (PIT). Our data suggest that the antibody against pentosan polysulfate-platelet complex also cross-reacts with heparin-platelet factor 4 complex. Due to its greater sensitivity and wider availability, this ELISA test should be used in cases where PIT is suspected./CASE REPORTS/ Pentosan polysulfate is a low-molecular-weight sulfated polysaccharide used as an antithrombotic drug. We present two patients who developed thrombocytopenia and venous thrombosis during treatment with pentosan polysulfate. The relationship between pentosan polysulfate and thrombocytopenia is supported by platelet aggregation and serotonin release tests. In the light of the literature and our two cases, it appears that pentosan polysulfate alone as standard heparin and low-molecular-weight heparin can induce thrombocytopenia and thrombosis. Platelet counts should therefore be periodically monitored during pentosan polysulfate treatment. In the case of pentosan polysulfate-induced thrombocytopenia, it seems that heparin or low-molecular-weight heparin should not be instituted during the acute phase even if platelet aggregation studies are negative, because of their low sensitivity. After remission of thrombocytopenia, whether or not glycosaminoglycans can be reinstituted, at least temporarily, after antibody had disappeared is still an open question.For more Human Toxicity Excerpts (Complete) data for Elmiron (9 total), please visit the HSDB record page.

Carcinogen ClassificationElmiron&regTR-512: Toxicology and Carcinogenesis Studies of Elmiron® (CASRN 37319-17-8) in F344/N Rats and B6C3F1 Mice (Gavage Studies) (2004 )09/05/02No EvidenceSome Evidence
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ Elmiron, a highly sulfated, semisynthetic pentose polysaccharide with properties similar to heparin, is used for the treatment of interstitial cystitis. Thirteen-week gavage studies were conducted by administering the drug in deionized water to F344/N rats and B6C3F1 mice once daily, 5 days per week for up to 13 consecutive weeks, at doses of 0, 63, 125, 250, 500, and 1,000 mg/kg body weight. No significant drug-related effects were observed in body weight, survival, clinical, and necropsy results. Significant organ weight increases were seen in the liver, lungs, and spleen of both species and the kidneys of rats, mainly in groups treated with 250 mg/kg/day and above. Hematological analysis indicated increases for both species in the white blood cell and lymphocyte counts. Sites of toxicity identified histopathologically were the rectum, liver, mesenteric and mandibular lymph nodes (both sexes), spleen (mice only), and lungs and kidneys (rats only). Lesions consisted mainly of infiltration into multiple tissues of vacuolated histiocytes, which, by histochemical investigation, indicated the presence of neutral and acidic mucins and lipidic material within the vacuoles. Transmission electron microscopy identified these vacuoles as lysosomal structures that exhibited a variety of contents. On the basis of our findings, we propose that Elmiron was absorbed through the focally disrupted rectal mucosa, was deposited in the lamina propria, accumulated within macrophages, and then was distributed by these cells or as a free chemical via the lymphatics and blood, to the various organ sites manifesting histiocytic infiltration. The cytoplasmic membrane-bound structures within macrophages were lysosomes containing membranous material of cellular origin and, perhaps, remnants of the deposited test material, Elmiron./LABORATORY ANIMALS: Chronic Exposure or Carcinogenicity/ Elmiron (sodium pentosan polysulfate) is used for the relief of urinary bladder pain associated with interstitial cystitis. The National Toxicology Program (NTP) tested this compound because of its orphan drug status and lack of information about its chronic toxicity and carcinogenicity. Groups of 50 male and 50 female F344/N rats were given Elmiron in de-ionized water by gavage at doses of 0, 14, 42, or 126 mg/kg to males and 0, 28, 84, or 252 mg/kg to females once daily, 5 days per week, for up to 2 years. The same numbers of male and female B6C3F1 mice were dosed similarly with 0, 56, 168, or 504 mg/kg. Elmiron administration produced no effect on the body weight of rats, male mice, or low- and mid-dose groups of female mice. The body weights of the high-dose female mice were significantly decreased relative to those of controls. Pairwise comparison showed that survival of all dosed groups of rats and mice was similar to that of the controls. Elmiron was not carcinogenic in F344/N rats. An increased incidence of liver hemangiosarcoma provided evidence of some carcinogenic activity for Elmiron in male B6C3F1 mice. Increased incidences of liver hemangiosarcoma, hepatocellular neoplasms (predominantly adenomas), and malignant lymphomas revealed carcinogenic activity of Elmiron in female B6C3F1 mice. Elmiron administration produced elevated occurrences of nonneoplastic lesions, such as vacuolated histiocytes in the rectum, lung, spleen (males only), and mesenteric lymph node in rats and liver, rectum, mesenteric lymph node, and spleen in mice. Myxomatous change, chronic inflammation, and squamous metaplasia (mice only) were observed in the large intestine, and lymphohistiocytic hyperplasia was found to be increased in the spleen of rats of both sexes treated with the highest dose. In the latter lesion, the histiocytes contained pale, finely granular cytoplasm and were not considered to represent the same change as the vacuolated histiocytes seen in the mesenteric lymph node and rectum. Under the conditions of these 2-year studies, Elmiron was carcinogenic to mice but not rats./LABORATORY ANIMALS: Chronic Exposure or Carcinogenicity/ Long term carcinogenicity studies of Elmiron in F344/N rats and B6C3F1 mice have been conducted. In these studies, Elmiron was orally administered once daily via gavage, 5 days per week, for up to 2 years. The dosages administered to mice were 56, 168 or 504 mg/kg. The dosages administered to rats were 14, 42, or 126 mg/kg for males, and 28, 84, or 252 mg/kg for females. The dosages tested were up to 60 times the maximum recommended human dose (MRHD) in rats, and up to 117 times the MRHD in mice, on a mg/kg basis. The results of these studies in rodents showed no clear evidence of drug-related tumorigenesis or carcinogenic risk./LABORATORY ANIMALS: Developmental or Reproductive Toxicity/ The potential reproductive toxicity of Elmiron (sodium pentosan polysulfate) in Sprague-Dawley rats was evaluated using the Reproductive Assessment by Continuous Breeding protocol. Elmiron has orphan drug status in the U.S. for compassionate treatment of interstitial cystitis. Dose levels were set at 111, 333, and 1000 mg/kg/day (L, M, and H, respectively) based on data obtained from a 90-day gavage study. Body weights of F1 H males and females were significantly decreased as early as Postnatal Day 4 and continued lower as the second generation matured. No breeding, fertility, or necropsy endpoint related to reproduction was altered in either generation. No differences were noted in F0 or F1 epididymal sperm morphology or density, sperm motion parameters, testicular spermatid head counts, percent normal sperm, or F1 estrous cyclicity. Changes suggestive of hypochromic anemia, platelet activation, and hyperproteinemia were noted in F0 hematology (26% increase in platelets in H males and 15% increase in MPV in male groups), F1 hematology (20% increase in platelets in H males and 10% increase in MPV in H males and females), and F1 clinical chemistry (20% increase in globulin in male groups, and a 7% increase in total protein and 22% decrease in A/G in M and H males). Treatment-related increases (10-53%) were noted in kidney, liver, and spleen weights and organ/body weight ratios in most F0 and F1 treated groups. In the F1 generation there was a treatment-related increase in renal pelvis dilatation in males (5, 0, 30, 30% in O, L, M, H) and females (10, 20, 10, and 30% in O, L, M, H) and an increase in uterine dilatation in females (15, 10, 20, and 30 in the O, L, M, H). Dose-related increases in incidence of microscopic findings included hepatocytic cytoplasmic vacuolization, bile duct hyperplasia, renal tubule cytoplasmic vacuolization, and renal tubule degeneration/dilatation. No reproductive toxicity was noted in either generation at doses up to 1000 mg/kg/day.For more Non-Human Toxicity Excerpts (Complete) data for Elmiron (11 total), please visit the HSDB record page.

National Toxicology Program StudiesGroups of 50 male and 50 female /rats/ were administered Elmiron in deionized water by gavage at doses of 0, 56, 168, or 504 mg/kg, 5 days per week, for 104 or 105 weeks. Survival of all dosed groups of mice was similar to that of the vehicle control groups. Mean body weights of males were similar to those of vehicle controls. Mean body weights of 504 mg/kg females were progressively less than those of the vehicle controls during the second year of the study. Increased incidences of hemangiosarcomas of the liver and hepatocellular neoplasms were observed in male and female mice. The incidences of hemangiosarcomas in the 504 mg/kg groups exceeded the historical control ranges for males and femalesboth the trend and the incidence in the 504 mg/kg groups were significant for males. Hemangiosarcomas in males and females were attributed to Elmiron administration. The incidence of hepatocellular adenoma in 504 mg/kg females was significantly increased and exceeded the historical control rangethe trends for hepatocellular adenoma and for hepatocellular adenoma or carcinoma (combined) were also significant in females and were attributed to Elmiron administration. There was also a marginal increase in the incidences of hepatocellular neoplasms in male mice, which may have been associated with Elmiron administration. Malignant lymphomas occurred with a positive trend in female micethe incidence in the 504 mg/kg group was also significantly increased and matched the upper limit of the historical control range. These malignant lymphomas may have been associated with Elmiron administration. Nonneoplastic lesions related to the administration of Elmiron occurred in the liver, rectum, mesenteric lymph node, and spleen of 504 mg/kg mice and to a lesser extent in 168 mg/kg mice. These lesions were similar to those observed in the 3-month study.Groups of 50 male and 50 female /rats/ were administered Elmiron in deionized water by gavage at doses of 0, 14, 42, or 126 mg/kg to males and 0, 28, 84, or 252 mg/kg to females, 5 days per week, for 104 or 105 weeks. Survival of all dosed groups of rats was similar to that of the vehicle control groups. Mean body weights of all dosed groups were similar to those of the vehicle controls throughout the 2-year study. Microscopically, myxomatous changes were present in the rectum of 56% of 126 mg/kg males and 83% of 252 mg/kg females. The incidences of chronic active focal alveolar inflammation of the lung were increased in all dosed groups. The incidences of histiocytic cellular infiltration of the mesenteric lymph nodes were increased in 42 and 126 mg/kg males and in 84 and 252 mg/kg females, and lymphohistiocytic hyperplasia was present in the spleen of 126 mg/kg males and 252 mg/kg females.Groups of five male and five female rats were administered 0, 33, 111, 333, 1,000, or 3,000 mg Elmiron/kg body weight in deionized water by gavage, 5 days per week, for 16 days. Elmiron administration had no effect on survival or body weight gain. Activated partial thromboplastin time was significantly increased in 3,000 mg/kg rats. Liver weights of 3,000 mg/kg rats were significantly greater than those of the vehicle controls. Hepatocellular cytoplasmic vacuolization occurred in all 3,000 mg/kg females.Groups of five male and five female mice were administered Elmiron in deionized water by gavage at doses of 0, 33, 111, 333, 1,000, or 3,000 mg/kg, 5 days per week, for 16 days. All mice survived to the end of the study. Mean body weight gains of male mice administered 333 mg/kg or greater were significantly greater than that of the vehicle control group. Liver weights of 1,000 and 3,000 mg/kg males were significantly increasedFor more National Toxicology Program Studies (Complete) data for Elmiron (7 total), please visit the HSDB record page.
