Claims (11)

1 . A method of lubricating a medical device for insertion into the body of a subject or a mucosal area of a subject, comprising applying to the medical device or the mucosal area of the subject in need an effective amount of a lubricating composition comprising an effective amount of chondroitin sulfate and hyaluronan.

2 . The method of claim 1 , wherein said chondroitin sulfate is CS4, chondroitin sulfate, CS6 chondroitin sulfate, or a mixture of CS4 and CS6 chondroitin sulfate.

3 . The method of claim 1 , wherein said effective amount of chondroitin sulfate is between about 0.1 grams to about 10 grams per unit dose of the lubricating composition.

4 . The method of claim 1 , wherein said effective amount of hyaluronan is about 10 mg to about 1000 mg of hyaluronan per unit dose of the composition per unit dose of the lubricating composition.

5 . The method of claim 1 , wherein said composition further comprises an effective amount of N-acetyl D-glucosamine.

6 . The method of claim 5 , wherein said effective amount of N-acetyl D-glucosame is between about 0.5 grams to about 10 grams per unit dose of the lubricating composition.

7 . The method of claim 1 , wherein said lubricating composition further comprises one or more physically acceptable excipients.

8 . The method of claim 1 , wherein said lubricating composition is in a formulation selected from a solution, emulsion, lotion, cream, suspensions, gel, semi-solid, and solid.
