🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works through the combined action of cetrimide and chlorhexidine gluconate. Cetrimide is a quaternary ammonium compound that acts as a cationic surfactant. It disrupts the lipid bilayer of bacterial cell membranes, leading to leakage of cellular contents and cell death. Chlorhexidine gluconate is a biguanide antiseptic that binds to negatively charged bacterial cell walls, disrupting the osmotic balance and causing precipitation of cytoplasmic contents. Together, they provide broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria, fungi, and some viruses. The combination is effective against a wide range of microorganisms and has a rapid onset of action.
