[Use and adverse reactions of local antibiotics and disinfectants on the skin]

Area of Science:

• Dermatology
• Infectious Diseases
• Microbiology

Background:

• Local antibiotics are crucial for managing moderately severe skin infections.
• Potential adverse reactions include contact allergy and bacterial resistance.
• Understanding the spectrum of activity for different topical agents is essential.

Purpose of the Study:

• To review the efficacy and appropriate use of various local antibiotics for skin infections.
• To highlight specific agents for Gram-positive and Gram-negative bacterial infections.
• To discuss the role of local antibiotics in managing resistant bacterial strains and carrier states.

Main Methods:

• Literature review of topical antibiotic applications in dermatology.
• Analysis of clinical evidence for agents like fusidic acid, tetracycline, mupirocin, silver sulfadiazine, erythromycin, and clindamycin.
• Discussion of antibiotic resistance mechanisms and prevention strategies.

Main Results:

• Fusidic acid and tetracycline are effective for Gram-positive cocci and secondary infected dermatoses.
• Mupirocin is indicated for Staphylococcus aureus nasal carriage and meticillin-resistant strains.
• Silver sulfadiazine targets Pseudomonas aeruginosa and other Gram-negative bacteria.
• Erythromycin and clindamycin are useful for mild acne vulgaris.

Conclusions:

• Local antibiotics provide valuable treatment options for diverse skin infections.
• Judicious use is necessary to mitigate the development of bacterial resistance.
• Specific agents are recommended based on the causative pathogen and clinical scenario.
