Abstract
(EN)
A pharmaceutical preparation comprises a stable suspension of a water insoluble alginate for external application to a patient. A colloidal suspension of calcium alginate is conveniently stabilized by use of xantham gum, and/or gellam gum, and/or locust bean gum which act as suspending and gelling agents. The preparation may have a variety of physical forms, ranging from a thin runny gel capable of direct application to the body surface, through a thick gel, to a self-supporting slab, pad or wafer of desired size, shape and thickness which may be held in place with a surgical dressing. The preparation may also be presented in the form of a surgical dressing which carries, e.g. is impregnated with or contains in slab or wafer form, a preparation of the invention. The alginate is haemostatic and also has healing and regranulation properties. The preparation can thus be used in treatment of bleeding wounds and injuries and also non-bleeding wounds such as burns, ulcers and many other conditions.

Une préparation pharmaceutique se compose d'une suspension stable d'un alginate insoluble dans l'eau, destinée à une application externe sur un patient. Une suspension colloïdale d'alginate de calcium est bien stabilisée au moyen d'une gomme de xantham, et/ou une gomme de gellam, et/ou une gomme de fève locuste, qui agissent comme agents de suspension ou de gélification. La préparation peut revêtir une diversité de formes physiques, qui vont d'un gel fin et coulant qui peut être appliqué directement sur la surface du corps humain, en passant par un gel épais, à une plaque, pastille ou rondelle autoporteuse de taille, forme et épaisseur désirées qui peuvent être maintenues en place au moyen d'un pansement chirurgical. La préparation peut également se présenter sous forme d'un pansement chirurgical qui, par exemple, en est imprégné ou qui contient une plaque ou une rondelle de cette préparation. L'alginate est hémostatique, il a aussi des propriétés curatives et de regranulation. Par conséquent, la préparation peut être utilisée pour traiter les plaies ouvertes et les lésions, et les blessures non ouvertes comme les brûlures, les ulcères et autres affections similaires.
