Opraclean® Dressing Materials help cleanse wounds by absorbing wound exudate, cell debris and bacteria. Opraclean® is equally effective in packing deep wound pockets and cavities. The iodoform-impregnated dressings have an antimicrobial effect. On contact with wound secretions, iodoform breaks down and continuously releases small amounts of iodine from the dressing. Iodine is known for its broad spectrum of action against numerous gram-negative, gram-positive, aerobic and anaerobic bacteria, as well as against many fungi and viruses. Another advantage: There is no known pathogen resistance to iodine.
