2. A method as recited in claim 1 , wherein the pentosan comprises pentosan polysulfate.
3. A method as recited in claim 1 , further comprising hyaluronic acid or a physiologically acceptable ester or salt thereof.
4. A method as recited in claim 1 , further comprising chondroitin sulfate.
5. A method as recited in claim 1 , wherein the liposomal carrier comprises liposomes having a mean diameter of 50 nanometers or less.
6. A method as recited in claim 1 , wherein the cystitis is interstitial cystitis, infectious cystitis, radiation cystitis, or chemical cystitis.
7. A method as recited in claim 1 , wherein the cystitis is interstitial cystitis.
8. A method as recited in claim 1 , wherein the cystitis is radiation cystitis.
9. A method as recited in claim 1 , wherein the cystitis is chemical cystitis.
10. A method as recited in claim 1 , further comprising co-administering DMSO with the pentosan in the liposomal carrier.
