Pharmacological properties

Pharmacotherapeutic group: Antiseptics and disinfectants, biguanides and amidines

ATC Vet Code: QD08AC02

5.1 Pharmacodynamic properties

Chlorhexidine is a bisbiguanide antiseptic and disinfectant effective against a wide range of bacteria, some fungi, and some viruses.

It is more effective against Gram-positive than Gram-negative bacteria, some species of Pseudomonas and Proteus being less susceptible. It inhibits mycobacteria. Chlorhexidine inhibits some viruses and is active against some fungi. It is inactive against bacterial spores at room temperature.

For pre-operative skin disinfection and hand washing, chlorhexidine is used as a 0.5% solution of the acetate or gluconate in alcohol (70%) or as in a 4% detergent solution of the gluconate.

For disinfection of wounds, burns, or other skin damage disorders, chlorhexidine is used as a 0.05% aqueous solution of the gluconate.

5.2 Pharmacokinetic properties

Chlorhexidine is poorly absorbed from the gastro-intestinal tract and skin.

Chlorhexidine was detected in low concentrations in the venous blood of 5 of 24 infants after bathing with a preparation containing chlorhexidine gluconate 4%. No adverse effects due to percutaneous absorption of chlorhexidine were observed.Low concentrations have been found in the venous blood of neonates following the topical use of a powder containing chlorhexidine 1%. Percutaneous absorption of chlorhexidine was reported in pre-term neonates (but not full term infants) treated with chlorhexidine 1% in alcohol for neonatal cord care; no such absorption occurred when a dusting powder containing chlorhexidine 1% and zinc oxide 3% was used.
