Promogran is a sterile freeze-dried wound dressing matrix comprised of 55% Collagen and 44% Oxidized RegeneratedIn the presence of exudate the Promogran Dressing transforms into a soft, conformable, biodegradable gel, and thus allows contact with all areas of the wound. Promogran Dressing maintains a physiologically moist microenvironment at the wound surface. This environment is conducive to granulation tissue formation, epithelialization and rapid wound healing.
