Current developments and prospects of the antibiotic delivery systems

Area of Science:

• Microbiology
• Pharmacology
• Biotechnology

Background:

• Antibiotics are vital for treating bacterial infections but face challenges due to rising antibiotic resistance.
• Bacterial genome plasticity and biofilm formation contribute to the ineffectiveness of current antibiotic therapies.
• Clinical failures of antibiotic therapy are linked to poor bioavailability, side effects, and inadequate drug accumulation at infection sites.

Purpose of the Study:

• To review novel strategies for enhancing antibiotic delivery and overcoming antimicrobial resistance (AMR).
• To explore the potential of various delivery systems in improving antibiotic efficacy.

Main Methods:

• Review of current literature on antibiotic resistance mechanisms.
• Analysis of emerging drug delivery systems including siderophores, antibodies, cell-penetrating peptides, antimicrobial peptides, bacteriophages, and nanoparticles.
• Discussion of the mechanisms by which these systems facilitate antibiotic transport across biological membranes.

Main Results:

• Several delivery systems show promise in overcoming biological barriers to antibiotic penetration.
• Tailoring delivery systems can target specific resistance mechanisms.
• Enhanced antibiotic accumulation at infection sites can be achieved through these novel approaches.

Conclusions:

• Siderophores, antibodies, cell-penetrating peptides, antimicrobial peptides, bacteriophages, and nanoparticles offer potential solutions to combat AMR.
• These strategies can improve antibiotic bioavailability, penetration, and accumulation, leading to more effective treatments.
• Further research and development of these delivery systems are essential for clinical application against resistant bacterial infections.
