Embodiment Construction

[0058] Other characteristics and advantages of the invention will become more apparent on reading the following description of a preferred embodiment of the invention given by way of example and with reference to the accompanying drawings.

[0059] Most unexpectedly, the Applicant has developed new dressings comprising a microadhesive interface comprising polysulfated oligosaccharides with a high sustained release of active ingredients.

[0060] These dressings are obtained using a method comprising the steps of depositing or incorporating in said dressing interface at least one polysulfated oligomeric compound having 1 to 4 saccharide units at the interface of the dressing intended to come into contact with the skin or the wound. For sugar compounds, the method further comprises treating with ethylene oxide.

[0061] These dressings comprise at least one compound selected from polysulfated oligosaccharides comprising 1 to 4 sugars and show a more sustained release of these ac...

Abstract

The present invention relates to novel dressings containing polysulfated oligosaccharides and having the controlled release of said active ingredients. The invention also relates to a method for preparing same, wherein the method comprises a treatment step using ethylene oxide. The invention also relates to the uses thereof for caring for wounds and for treating and / or preventing scars and stretch marks.

Description

[0001] The present invention relates to novel dressings comprising polysulfated oligosaccharides for the sustained release of said active ingredients. It also relates to a method for preparing said dressing comprising a treatment step with ethylene oxide. It also relates to the use of said dressing for wound care and for the treatment and / or prevention of cicatrices and stretch marks. Background technique [0002] Oligosaccharides are carbohydrates whose hydrolysis provides only oses. It is a sugar formed by combining at least two molecules of monosaccharides (or sugars). Oligosaccharides include sucrose (also known as saccharose), which is a disaccharide formed by the condensation of two sugars: one molecule of glucose and one molecule of fructose. [0003] A variety of sulfated oligosaccharide compounds are known in the literature and possess a variety of biological, cosmetic and / or therapeutic activities. These compounds include in particular the different salts of sucro...
