The specification discloses an alginate foam composition dressing which may be prepared with or without a backing. The foam dressing exhibits unique capability in including soluble or insoluble medicaments as part of the alginate foam composition, attributes not inherent in alginate dressings prepared by spinning. The dressings so prepared also eliminate the need for adhesives and secondary dressings for retaining an alginate dressing on a wound site. The foam is formed by addition of a di- or trivalent metal cation to a solution of water-soluble alginate, followed by addition of a gaseous foam-forming or effervescent compound and an acid, then drying the foam. |
