The Sorbact® method is an innovative approach to reduce bioburden in wounds without using any chemically active agents. Instead, a physical principle is used to bind bacteria and fungi to the dressing in the presence of moisture.

The Sorbact®  method was invented by two Swedish professors, Torkel Wadström and Stellan Hjertén. It is based on the knowledge that two hydrophobic particles bind together in the presence of moisture. Common pathogenic microorganisms, such as Staphylococcus aureus, Streptococcus species, Escherichia coli, Pseudomonas aeruginosa and Candida albicans, are hydrophobic and therefore bind to the unique surface of Sorbact®. These are removed from the wound each time the dressing is changed.

Effective against multi-resistant bacteria

Fighting multi-resistant bacteria has become increasingly important in wound treatment and hospital management. The Sorbact® method is also effective against MRSA (methicillin-resistant Staph. aureus) and VRE (vancomycin-resistant Enterococcus) as their resistance against antibiotics does not change their hydrophobic properties nor their ability to bind to Sorbact®. Mechanisms of resistance to the Sorbact® method have not been described.

Advantages over common antimicrobial approaches

The natural binding and removal of microorganisms implies that release of bacterial endotoxins in the wound are prevented. As opposed to commonly used antiseptics, antibiotics and antimicrobial dressings, Sorbact® releases no chemical agents into the wound or cause damage to normal cells in the wound bed. Therefore, Sorbact® can be used prophylactic for wounds at risk of infection or re-infection and  during the entire healing process in wounds that are infected or are being prevented from healing by microorganisms. All Sorbact® products can also be used without hesitation during pregnancy and breastfeeding as well as on children.
