Colistin has seen a resurgence as a last-resort antibiotic due to rising multidrug-resistant Gram-negative bacteria. Its bactericidal effect is achieved by fatally disrupting the bacterial cell membranes, a complex process initiated by targeting the lipopolysaccharide (LPS) layer.

According to a 2007 study, topical triple-antibiotic ointment (TAO) is a safe and effective agent for preventing infections in minor skin trauma. This common first-aid treatment is what is triple antibiotic therapy, combining three different antibiotics to offer broad-spectrum protection against bacterial infections.

Pharmacological confusion can be dangerous, and the term 'pol' is one such ambiguity, as it can refer to several different medications or concepts. While a common brand name like 'Pol 40mg' designates a proton pump inhibitor, the most clinically significant interpretation within the context of serious infections points to the Polymyxin class of antibiotics.

According to the World Health Organization, antibiotic resistance is one of the top three global threats to human health. In this context, polymyxins have re-emerged as crucial "last-line" antibiotics used to combat serious infections caused by multidrug-resistant Gram-negative bacteria when other drugs have failed.

Originally abandoned in the 1970s due to severe toxic side effects, colistin, or polymyxin E, has re-emerged as a crucial 'last-resort' antibiotic for treating multi-drug resistant (MDR) Gram-negative bacterial infections. This resurgence has made understanding what class of drug is colistin, its unique mechanism, and its risks a critical aspect of modern pharmacology.

With the global increase in multi-drug resistant (MDR) Gram-negative bacterial infections, colistin has re-emerged as a crucial last-resort antibiotic. However, its widespread use has renewed concerns about its most significant adverse effect, nephrotoxicity, and understanding its mechanism is vital for safer clinical use.

Polymyxins, discovered in 1947, have resurged as a crucial "last-line" defense against extremely multidrug-resistant Gram-negative bacteria due to their distinctive mechanism of action. This resurgence has brought renewed focus on the question: *What is polymyxin?* This class of antibiotics represents an important tool for serious infections when other options have failed.
