Method of attenuating neurogenic swelling or neurogenic inflammation

1. A method of attenuating neurogenic swelling or neurogenic inflammation within the tissue of a patient, the method comprising applying a composition comprising a hydrophilic foam substrate and a hydrophilic agent to a portion of the surface of the skin of the patient in an amount and at a location sufficient to attenuate swelling or inflammation within the tissue, wherein the neurogenic swelling or neurogenic inflammation is associated with skin tissue other than the portion of the surface of the skin where the composition is applied or the neurogenic swelling or neurogenic inflammation is associated with a tissue other than skin.

2. The method of claim 1 , wherein the neurogenic swelling or neurogenic inflammation is a response to a noxious stimulus.

3. The method of claim 1 , wherein the neurogenic swelling or neurogenic inflammation is a symptom of a disease.

4. The method of claim 1 , wherein the tissue is muscle, bone, ligament, or skin.

5. The method of claim 1 , wherein the hydrophilic foam comprises the in situ reaction product of an isocyanate-capped polyether prepolymer.

6. The method of claim 5 , wherein the prepolymer is selected from the group consisting of isocyanate-capped polyether polyols having an isocyanate equivalent weight of from about 0.5 meq/g to about 3.0 meq/g, and mixtures thereof.

7. The method of claim 1 , wherein the hydrophilic agent is capable of absorbing water.

8. The method of claim 1 , wherein the hydrophilic agent is polymeric.

9. The method of claim 1 , wherein the hydrophilic agent is selected from the group consisting of starch grafted copolymers of acrylate salts, starch grafted copolymers of acrylamide salts, polyacrylate salts, and mixtures thereof.

10. The method of claim 1 , wherein the hydrophilic agent comprises an additive selected from the group consisting of methylcellulose, guar gum, pectin, karaya gum, chitosan, agar, acacia powder, carrageenan, gelatin, and mixtures thereof.

11. The method of claim 1 , wherein the hydrophilic agent is incorporated into the foam substrate.

12. The method of claim 1 , wherein the composition further comprises an alcohol.

13. The method of claim 12 , wherein the alcohol is selected from the group consisting of water soluble monols, diols and polyhydric alcohols.

14. The method of claim 12 , wherein the alcohol is selected from the group consisting of ethanol, isopropyl alcohol, propylene glycol, polyethylene glycol, polypropylene glycol, glycerin, 1,2,4-butanetriol, trimethylolpropane, sorbitol, pentaerythritol, and mixtures thereof.

15. The method of claim 12 , wherein the alcohol is incorporated into the foam substrate.

16. The method of claim 1 , wherein the composition further comprises a therapeutic agent.

17. The method of claim 16 , wherein the therapeutic agent is selected from the group consisting of soluble collagen, hydrolyzed collagen, collagen amino acids salt free, hydrolyzed animal protein and hyaluronic acid, an ointment including methyl salicylate and menthol and hydrocortisone acetate, polymers with medicinal properties, and trans-retinoic acid.

18. The method of claim 16 , wherein the therapeutic agent is incorporated into the foam substrate.

19. The method of claim 1 , wherein the composition further comprises a wetting agent.

20. The method of claim 19 , wherein the wetting agent is a non-ionic surfactant selected from the group consisting of block copolymers of ethylene oxide and propylene oxide, ethoxylated sorbitan fatty acid esters, glycerol esters, polyglycerol esters, silicone fluids, and mixtures thereof.

21. The method of claim 19 , wherein the wetting agent is incorporated into the foam substrate.

22. The method of claim 1 , wherein the patient is a human.

23. The method of claim 1 , wherein the entirety of the portion of skin is unbroken.
