Cetrimide Solution, commonly known as Cetrilak, is an antiseptic solution used for disinfecting wounds and skin surfaces. It contains cetrimide, which is a quaternary ammonium compound with antimicrobial properties. Cetrilak is typically used to clean and sterilize minor cuts, burns, and scrapes, but can also be used for general skin cleansing purposes. It works by disrupting the cell membrane of bacteria, fungi, and viruses, ultimately killing them. Cetrilak is available in various concentrations, and should be used according to the instructions provided by a healthcare professional.
