MedKoo CAT#: 317505

CAS#: 18472-51-0 (gluconate)

Description: Chlorhexidine digluconate solution is a bis-biguanide family cationic broad spectrum antibiotic. Studies indicate that chlorhexidine digluconate solution functions, via destabilization of the outer bacterial membrane, which resulted in the release of periplasmic enzymes in gram negative bacteria. In addition, Chlorhexidine digluconate solution inhibits oxygen utilization which leads to a reduction in bacterial ATP. Furthermore, Chlorhexidine digluconate solution is very effective against bacteria such as Propionibacterium, Selenomonas, and cocci resembling Veillonella.
