Innovative Strategies to Combat Antibiotic Resistance: Emerging Trends and Future Directions

Aim: Antimicrobial resistance (AMR) represents a critical global health challenge exacerbated by the overuse and misuse of antibiotics in human, animal, and environmental contexts. This study aims to examine the barriers to addressing AMR, with a specific focus on scientific, economic, and regulatory challenges in the development and adoption of novel antimicrobial strategies. Methods: This review synthesizes current literature on innovative therapeutic approaches, such as bacteriophage therapy and antimicrobial peptides, alongside an analysis of global policy initiatives, including the WHO Global Action Plan on AMR and the PASTEUR Act. Emphasis is placed on identifying key obstacles and potential solutions within the realms of antibiotic R&D and policy frameworks. Results: Findings highlight the significant promise of alternative therapies and policy-driven incentives to address AMR. However, limitations such as scientific hurdles, economic disincentives, and disparities in regulatory enforcement hinder progress. Novel policy measures like subscription-based models and improved diagnostic tools have shown potential to close existing gaps. Conclusion: Collaborative global efforts are essential to address AMR effectively. Sustainable funding mechanisms, advanced diagnostic technologies, and integrated One Health approaches must be prioritized to bridge gaps between science, policy, and practice. By addressing these challenges, the global community can mitigate the escalating threat of AMR and safeguard the efficacy of antibiotics for future generations.
