Abstract:
The emergence of methicillin-resistant Staphylococcus aureus (MRSA) imposes a major challenge for the treatment of infectious diseases with existing antibiotics. MRSA associated with superficial skin and soft tissue infections (SSTIs) is one of them, affecting the skin's superficial layers, and it includes impetigo, folliculitis, cellulitis, furuncles, abscesses, surgical site infections, etc. The efficient care of superficial SSTIs caused by MRSA necessitates local administration of antibiotics, because oral antibiotics does not produce the required concentration at the local site. The topical administration of nanocarriers has been emerging in the area of drug delivery due to its advantages over conventional topical formulation. It enhances the solubility and permeation of the antibiotics into deeper layer of the skin. Apart from this, antibiotic resistance is something that needs to be combated on multiple fronts, and antibiotics encapsulated in nanocarriers help to do so by increasing the therapeutic efficacy in a number of different ways. The current review provides an overview of the resistance mechanism in S. aureus as well as various nanocarriers reported for the effective management of MRSA-associated superficial SSTIs.
Insights
Nanocarriers offer a promising solution for treating methicillin-resistant Staphylococcus aureus (MRSA) skin infections. Encapsulating antibiotics in nanocarriers enhances local drug delivery and combats antibiotic resistance effectively.
Area of Science:
- Infectious Diseases
- Nanotechnology
- Dermatology
Background:
- Methicillin-resistant Staphylococcus aureus (MRSA) presents a significant challenge in treating infectious diseases.
- Superficial skin and soft tissue infections (SSTIs) caused by MRSA require effective local antibiotic delivery.
- Conventional topical formulations often lack sufficient antibiotic concentration at the infection site.
Purpose of the Study:
- To review the mechanisms of antibiotic resistance in Staphylococcus aureus.
- To explore the application of nanocarriers for managing MRSA-associated superficial SSTIs.
- To highlight the advantages of nanocarrier-based topical drug delivery.
Main Methods:
- Literature review of studies on MRSA resistance mechanisms.
- Analysis of research on nanocarrier systems for topical antibiotic delivery.
- Synthesis of information on nanocarrier-enhanced therapeutic efficacy for SSTIs.
Main Results:
- Nanocarriers improve antibiotic solubility and skin permeation for enhanced local treatment.
- Encapsulation in nanocarriers can increase the therapeutic efficacy of antibiotics against MRSA.
- Various nanocarrier platforms show potential for combating antibiotic resistance.
Conclusions:
- Nanocarrier-based topical delivery is a promising strategy for MRSA superficial SSTIs.
- This approach addresses the limitations of conventional treatments and enhances antibiotic effectiveness.
- Further research into nanocarrier systems is crucial for combating antibiotic resistance.
