Chlorhexidine

• Description :

  Chlorhexidine is a orally active cationic antimicrobial agent that targets microbial cell membranes. Chlorhexidine binds to cell membrane phospholipids non-specifically, destroys membrane structure and induces leakage of cell contents. Chlorhexidine has broad-spectrum bactericidal activity against both Gram-positive and Gram-negative bacteria. Chlorhexidine can interfere with membrane permeability, cause protein precipitation and energy metabolism disorders, such as rapid inhibition of microbial growth and induction of cell death (necrosis or apoptosis) [1][2][3].
