Antiseptics

About

Antiseptics are antimicrobial substances applied to living tissues to prevent infections and promote healing. They are crucial in medical settings, particularly in surgeries, where they significantly reduce the risk of surgical infections by sterilizing the skin and equipment. The use of antiseptics has a long history, with early adopters like Joseph Lister popularizing their use in the 19th century based on Louis Pasteur's germ theory. Common antiseptics include alcohols, iodine, and chlorhexidine, each with different mechanisms of action and uses. Antiseptics are distinguished from disinfectants, which are used on non-living surfaces, and antibiotics, which treat internal infections. They are effective against a broad spectrum of microorganisms, including bacteria, viruses, and fungi. While antiseptics are generally safe for topical use, there are concerns about long-term safety and potential microbial resistance. Proper use and handling are essential to maximize their benefits while minimizing risks. Antiseptics play a vital role in healthcare and public health by preventing infections and promoting cleanliness.
