ATC Group: D08AC Biguanides and amidines

Chlorhexidine is an antimicrobial agent, active against a broad spectrum of Gram-positive and Gram-negative organisms, yeasts, fungi, opportunistic anaerobes and aerobes. Chlorhexidine is mainly a “membrane-acting” agent that destroys the outer membrane of the bacteria. It is inactive on bacterial spores unless the temperatures are high.

Dibrompropamidine is a member of the aromatic diamidine group of compounds, which possess bacteriostatic properties against a wide range of fungi and bacteria. These diamidines exert antibacterial action against pyrogenic cocci, antibiotic resistant staphylococci and some gram-negative bacilli. The activity of the diamidines is retained in the presence of organic matter such as pus and blood.

Polihexanide is a broad-spectrum antiseptic with excellent tolerance and a low-risk profile. The physicochemical action on the bacterial envelope prevents or impedes the development of resistant bacterial strains. Thus, polihexanide is particularly suitable and useful in the struggle against multidrug-resistant bacteria.

Propamidine is a member of the aromatic diamidine group of compounds which possess bacteriostatic properties against a wide range of organisms. These diamidines exert antibacterial action against pyrogenic cocci, antibiotic resistant staphylococci and some Gram-negative bacilli, the activity of the diamidines being retained in the presence of organic matter such as tissue fluids, pus and serum.
