Omiganan is primarily used as an antimicrobial agent, particularly in the treatment of skin infections. It is effective against a broad spectrum of bacteria, including antibiotic-resistant strains like MRSA. The compound is often applied topically to prevent infections in catheter sites and to treat acne vulgaris due to its ability to reduce bacterial load on the skin. Additionally, omiganan is being explored for its potential in managing other dermatological conditions, such as atopic dermatitis, by controlling microbial growth and reducing inflammation. Its mechanism of action involves disrupting bacterial cell membranes, making it a valuable option in combating localized infections.
