A Review of Alternative Pharmaceutical Strategies Against the Global Threat of Antimicrobial Resistance

This review paper investigates the primary biochemical pathways that bacterial "superbugs" utilize to evade destruction, including cellular efflux pumps and enzymatic degradation. Furthermore, it explores the cutting-edge pharmaceutical interventions currently under development—specifically bacteriophage therapy, synergistic combination molecular targeting, and antimicrobial peptides. Ultimately, this paper highlights the shifting responsibility of the global pharmacist from a traditional dispenser of medicines to an essential strategist in advanced molecular design and international antimicrobial stewardship.Bacteria develop antibiotic resistance through vertical evolution and horizontal gene transfer, deploying mechanisms like enzymatic degradation via beta-lactamases and efflux pumps to neutralize drugs. Furthermore, resistance is achieved through target modification and reduced membrane permeability, where bacteria alter target sites or limit antibiotic entry, necessitating new pharmaceutical approaches.
