Antibiotic last line of defence" antibiotic. Per "The ICU Book" "The first rule of antibiotics is try not to use them, and the second rule is try not to use too many of them." Inappropriate antibiotic treatment and overuse of antibiotics have contributed to the emergence of antibiotic-resistant bacteria. Self-prescribing of antibiotics is an example of misuse. Many antibiotics are frequently prescribed to treat symptoms or diseases that do not respond to antibiotics or that are likely to resolve without treatment. Also, incorrect or suboptimal antibiotics are prescribed for certain bacterial infections. The overuse of antibiotics, like penicillin and erythromycin, has
Antibiotic synergy level, the boosted antimicrobial potency provided by synergy allows the body to more rapidly clear infections, resulting in shorter courses of antibiotic therapy. Shorter courses of therapy in turn reduce the effects of dose-related toxicity, if applicable. Additionally, synergy aids in total bacterial eradication, more completely removing an infection than would be possible without synergy. At a higher level, synergistic effects are useful for combating resistant bacterial strains through increased potency and for stalling the spread of bacterial resistance through the total eradication of infections, preventing the evolutionary selection of resistant cells and strains. Current research on antibiotic synergy and
