THERAPEUTIC GROUP: Antiseptics and disinfectants

Mechanism of action NEOXENE ® Chlorhexidine

NEOXENE ® is a drug based on Chlorhexidine, a structurally complex molecule consisting of a bivalent chemical structure characterized by cationic residues and highly lipophilic groups, which allow it to interpose itself in the bacterial membrane, altering its structure and function.
More precisely, Chlorhexidine behaves at low concentrations like a normal detergent, destructuring the plasma membrane and compromising the cellular network, thus causing a loss of enzymatic function, at high concentrations like a real antibiotic, altering the cytoplasmic characteristics and exerting an action direct bactericide against Gram positive, Gram negative bacteria and on some species of Fungi.
The topical application and the low degree of systemic absorption make this therapy particularly safe, significantly reducing the risk of side effects and systemic complications.
