WHAT ARE TOPICAL ANTIMICROBIALS AND HOW DO THEY WORK?
Topical antimicrobials are medications used to treat skin infections caused by bacteria and reduce the redness, swelling, itching, and discomfort of various skin conditions. They play a crucial role in the prevention and treatment of primary and secondary superficial bacterial infections. They are often used as a first aid in minor skin abrasions and wounds.
Topical antimicrobials work in the following ways:
- They inhibit the growth of micro-organisms (fungi, viruses, bacteria), exerting a fast and prolonged antibacterial effect.
- They easily diffuse through cells with minimal toxicity and have a sparse activity against normal skin flora.
- In addition, topical antimicrobials possess bactericidal activity; they eventually kill the invading bacteria.
Topical antimicrobials are available in the form of creams, ointments, scrubs, lotions, and swabs.
