Topical effect of benzalkonium bromide on wound healing and potential cellular and molecular mechanisms.

ABSTRACT: Benzalkonium bromide (BB) has been widely used as a skin antiseptic for wound management. However, BB had proinflammation and reactive oxygen species (ROS) induction effect, making its role in wound healing complex and unclear. A rat full-thickness skin defect wound model was established. The effects of BB, povidone iodine (PVP-I), chlorhexidine gluconate (CHG), and normal saline (NS) on wound healing and infection control were then evaluated based on wound healing rate (WHr) and bacterial killing. The wound tissues were sectioned for histopathological evaluation and nuclear factor E2 related factor 2 (Nrf2) expression determination. The ROS production, Nrf2 activation, and heme oxygenase 1 (HO-1) expression of the HaCat cells and the cytotoxicity treated with BB were further explored. Com
