Bacteriophage Therapy: Overcoming Antimicrobial Resistance Through Advanced Delivery Methods
Abstract
Microbial resistance to antibiotics necessitates the development of alternative treatments to address the challenges posed by severe bacterial infections. Bacteriophages are regaining clinical relevance, but the effectiveness of phage therapy depends directly on the route of administration and the carrier used. This review provides a critical overview of the therapeutic potential of phages, emphasizing different strategies for delivery to the site of infection. We focus on the preclinical and clinical data on phage therapies using various routes of administration, such as oral, intravenous, inhalation, topical, and local administration to joints and bones. In view of different phage formulations, including liquid suspension, phages immobilized in polymers or liposome-based carriers, we highlight the potential challenges and obstacles that may affect phage stability and bioavailability and limit the successful outcome of therapy. This review serves to enhance the understanding of the integration of materials engineering with clinical practice and production standardization, to address these issues. Additionally, a clear knowledge of the bacteriophage and pharmacokinetics of phage preparations is necessary to implement safe and efficacious bacteriophage treatment in the era of antimicrobial resistance.
