olanexidine

Olanexidine is a monobiguanide compound developed as a topical antiseptic with potent bactericidal and bacteriostatic activity. It is particularly effective against a wide range of bacteria, especially Gram-positive cocci such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci. Olanexidine acts by binding to bacterial cell membranes, disrupting membrane integrity and causing irreversible leakage of intracellular components. At higher concentrations, it also denatures proteins leading to aggregation of bacterial cells. This mechanism differs slightly from that of other biguanides like chlorhexidine. The drug was synthesized in 1997 and later formulated as the gluconate salt for improved solubility and efficacy[2][6][8]. Its primary clinical use is as an antiseptic preparation for skin disinfection to prevent surgical site infections (SSI), particularly in settings where resistance to other agents like chlorhexidine or povidone-iodine may be present[7].
