Overview Askina® Calgitrol® Paste is a sterile, primary wound dressing made from an ionic silver alginate matrix in paste form. It is specifically designed for the management of chronic wounds that are infected or at high risk of infection. The paste formulation, rich in water content, allows for the immediate availability of silver ions upon application. Through an ionic exchange with the wound exudate, it provides a sustained and controlled release of silver ions to the wound bed, supporting effective antimicrobial protection and optimal healing conditions. Supplied sterile in a 15 g tube with a fine cannula applicator, the design allows for easy and precise application into tunnels, sinuses, and deep wounds, ensuring complete coverage and close wound contact.
