Mechanism of action

Chlorhexidine works by binding to and disrupting the cell membranes of microorganisms, causing leakage of cellular contents and protein denaturation. At higher concentrations it is bactericidal (kills bacteria), while at lower concentrations it can be bacteriostatic (inhibits growth). It is effective against a wide range of gram-positive and gram-negative bacteria, as well as some fungi and viruses.
