    Omiganan Pentahydrochloride is a pentahydrochloride salt of omiganan, a synthetic cationic antimicrobial peptide with wide-spectrum activity against both gram-positive and gram-negative bacteria and fungi. Omiganan pentahydrochloride, an analog of indolicidin, acts by disrupting bacterial cytoplasmic membranes and has been tested in a topical gel for the prevention of catheter-related bloodstream infections.
