Antimicrobials, a broad category of medications, play a pivotal role in combating various microorganisms, including bacteria, viruses, fungi, and parasites. Antibiotics, a subset of antimicrobials, specifically target bacteria, disrupting their growth or causing their demise. Common antibiotics like penicillins, cephalosporins, and tetracyclines have revolutionized medicine, transforming the landscape of infectious disease treatment. Antivirals, another subgroup, focus on viral infections, inhibiting viral replication or entry into host cells. Medications such as oseltamivir (Tamiflu) for influenza exemplify the antiviral class. Antifungals combat fungal infections, and antiparasitics target parasitic organisms, collectively contributing to the comprehensive field of antimicrobial therapeutics. However, the emergence of drug-resistant strains poses a global health threat, necessitating the development of novel antimicrobials, enhanced diagnostics, and robust stewardship programs to optimize their use and mitigate resistance.
