Colloidal drug delivery systems for infectious diseases of skin

Abstract

Infectious skin diseases represent a major global health burden, demanding effective and affordable treatments. Conventional therapies often face challenges such as reduced bioavailability, enzymatic degradation, low permeability, and poor solubility. Colloidal-based transdermal drug delivery systems, including liposomes, ethosomes, niosomes, nanoemulsions, polymeric nanoparticles, micelles, solid lipid nanoparticles, etc., have emerged as promising alternatives. In brief, these colloidal systems enhance drug penetration, stability, biocompatibility, and customized release while improving antimicrobial efficacy against various pathogens and minimizing systemic side effects. In conclusion, colloidal formulations offer a targeted, efficient approach, optimizing therapeutic outcomes, improving patient compliance, and advancing the treatment of infectious skin diseases.
