antisettici

Antisettici are antimicrobial substances that are applied to living tissue and skin to reduce the possibility of infection, sepsis, and disease. They work by killing or inhibiting the growth of microorganisms such as bacteria, viruses, and fungi. Antisettici are distinct from antibiotics, which are used internally to fight infections. The use of antisettici is a critical component of hygiene and infection control in healthcare settings, as well as in everyday life.

Common examples of antisettici include alcohol-based solutions like ethanol and isopropyl alcohol, hydrogen peroxide, and iodine compounds. Phenolic compounds were among the earliest widely used antisettici. The effectiveness of an antiseptic is often measured by its spectrum of activity (the range of microorganisms it affects) and its speed of action.

The application of antisettici is crucial in various situations. In surgery, skin preparation with antisettici significantly reduces the risk of surgical site infections. Healthcare professionals use them for hand hygiene before patient contact and after. In first aid, they are used to clean wounds and prevent infection. Consumer products like mouthwashes, hand sanitizers, and disinfectant wipes also utilize antiseptic agents. It is important to note that while effective, some antisettici can cause irritation or allergic reactions in some individuals, and their overuse can potentially contribute to the development of antimicrobial resistance in some microorganisms. Proper selection and use according to guidelines are therefore essential.
