PHMB Alginate Dressing
Great Innovation leads to the world’s first Alginate Dressing with antimicrobial PHMB.
LUOFUCON® PHMB Alginate Dressing is a sterile, single-use dressing consisting of calcium alginate fiber treated with polyhexamethylene biguanide (PHMB)，which is a brand new advanced wound care product. It solves the passivated problem of chemical reaction between alginate and PHMB, which provides safe and good 7-day antimicrobial activities for infected wounds. This dressing not only has alginate property of providing moist wound environment, but also offers PHMB advantage of highly effective safety.
Unlike regular impregnated manufacturing method of the other PHMB wound dressings, LUOFUCON® PHMB Alginate Dressing achieves that a lower content of PHMB has sustained broad-spectrum antibacterial effect by using state-of-the-art technology to bond PHMB onto alginate fibers at the very beginning. Bacteria and moisture are well managed in the dressing. It protects against the development of wound infection by decreasing the bioburden in the dressing and bacterial penetration through the dressing.
Effectiveness against MRSA and VRE
Experimental pictures and data show that LUOFUCON® PHMB Antibacterial Alginate Dressing has rapid effectiveness against multi-drug resistant bacteria, such as MRSA and VRE, with a 99.99% bactericidal rate on the first day, and maintains this effect for the next 2-7 days.
Through years of technical research, FORYOU MEDICAL innovated Antibacterial Laboratory has invented the patented technology of PHMB antibacterial alginate fiber and the corresponding preparation method of antibacterial dressing*. By grafting and loading PHMB on alginate fiber at the very beginning, the patented technology not only solves the technical problem of rapid passivation of antibacterial activity after mixing PHMB and alginate, but also overcomes the problem of easy free releasing of PHMB. It achieves long-term good antibacterial activity with low content, guarantees the antibacterial performance, and improves the safety and effectiveness.
* This technology has been patented in China, the United States and the European Union, the corresponding patent numbers are: CN107385917A, US 2019/0284727 A1, EP3660191 A1.
The carboxylated alginate fiber is grafted with PHMB by amide reaction to avoid the reaction between guanidine group and the anion in alginate, and retain the antibacterial activity of guanidine group in PHMB.
Grafting technology firmly anchors PHMB in alginate fibers. Compared with other impregnated PHMB dressings, LUOFUCON® PHMB Alginate Dressing does not release free PHMB into the wound bed, preventing PHMB from causing additional irritation to the fragile new tissues and providing gentle care to the wound.
How does PHMB work?
PHMB has been in use for 60 years in Europe and US. It is highly cationic, and attracts various kinds of bacteria, which are usually negatively charged. It is believed to adhere to and disrupt target cell membranes, causing them to leak potassium ions and other cytosolic components, which results in cell death*.
