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. These studies also indicate that the inner membrane in gram negative bacteria was not affected by the solution, however there was inhibition of active transport for small molecules entering the Furthermore, Chlorhexidine digluconate solution is very effective against bacteria such as Propionibacterium, Selenomonas, and cocci resembling Veillonella.
