Claims57
(canceled)
The method according to claim 47, wherein the hydrogel comprises at least one gel-forming substance selected from the group consisting of agar, alginates, alginic acids, Arabic gum, gelatine, starch, tragacanth gum, methylcelluloses, hydroxyethylcelluloses, carboxymethylcelluloses, polyacrylic acids and combinations thereof.
The method according to claim 47, wherein the preparation further comprises a liposome forming material.
The method according to claim 47, wherein the preparation further comprises a film forming substance.
The method according to claim 47, wherein the preparation further comprises at least one antiseptic agent.
The method according to claim 47, wherein the preparation further comprises one or more additives selected from the group consisting of adjuvants, conserving agents, antioxidants, consistency forming additives and pH-adjusting agents.
The method according to claim 47, wherein the preparation further comprises a wound-healing promoting agent.
The method according to claim 47, wherein the preparation further comprises a suitable pharmaceutically acceptable medium.
The method according to claim 47, wherein the preparation releases at least 8%, of the liquid from a test substrate.
The method according to claim 47, wherein liquid absorption of the hydrogel is less than 15%.
The method according to claim 47, wherein the hydrogel is formed from a pre-gel at the desired locus by evaporation of at least one volatile component or by absorption of a liquid component by body tissue.
(canceled)
The method according to claim 57, wherein the preparation is free of particulate carriers.
The method according to claim 57, wherein the preparation is free of antiseptic agents.
The method according to claim 57, wherein the preparation is free of anti-inflammatory agents.
The method according to claim 57, wherein the preparation is free of pharmaceutically active agents.
The method according to claim 57, wherein the preparation is free of film-forming substances.
The method according to claim 57, wherein the hydrogel comprises at least one gel-forming substance selected from the group consisting of agar, alginates, alginic acids, Arabic gum, gelatine, starch, tragacanth gum, methylcelluloses, hydroxyethylcelluloses, carboxymethylcelluloses, polyacrylic acids and combinations thereof.

A preparation for wound healing comprising a hydrogel wherein the capability of the preparation to release liquid is greater than its capability to absorb liquid and wherein the preparation does not contain liposomes and iodine.
A method for treating a wound, wherein said method comprises administering, to the wound, a preparation comprising a hydrogel;
- wherein the capability of the hydrogel to release liquid is greater than its capability to absorb liquid.
The method for treating a wound, wherein said method comprises administering, to the wound, a preparation comprising a hydrogel;
- wherein
- (a) the capability of the hydrogen to release liquid is greater than its capability to absorb liquid, and
- (b) the preparation is free of liposomes and iodine.
