Antiseptic

An Antiseptic is a substance that inhibits the growth and reproduction of microorganisms such as bacteria, fungi, or viruses. Antiseptics are commonly used in medical settings to prevent infections and are also found in many personal care products.

Mechanism of Action

Antiseptics work by disrupting the cellular processes of microorganisms, thereby preventing their growth and proliferation. This can be achieved through various mechanisms, such as disrupting cell membranes, denaturing proteins, or interfering with metabolism.

Types and Uses

• Different types of antiseptics are used for different applications:
• Alcohol: Alcohols like ethanol and isopropanol are used for skin disinfection before injections or minor surgical procedures.
• Iodine: Iodine and iodine-based compounds, such as povidone-iodine, are used in surgical settings for skin and mucous membrane disinfection.
• Chlorhexidine: Chlorhexidine is used for skin disinfection and as a mouthwash to prevent dental plaque.
• Hydrogen peroxide: Hydrogen peroxide is used for wound cleansing and disinfection of non-living surfaces.

Safety and Side Effects

While antiseptics are generally safe, they can cause side effects such as skin irritation or allergic reactions. Some antiseptics can also be toxic if ingested or used improperly.
