A comparison of sodium fusidate ointment and mupirocin ointment in superficial skin sepsis
Abstract:
Sodium fusidate ointment and mupirocin ointment were compared in 354 patients with superficial skin sepsis. The ointments were applied 3-times daily, or once daily when covered by a dressing, and the response assessed after 6 to 8 days. Both preparations proved effective clinically with 86% of patients responding. There was no difference between the two preparations in cases of primary infection (85% to both ointments), including a sub-group with impetigo (sodium fusidate 88% and mupirocin 84%), or secondary infection (sodium fusidate 81% and mupirocin 89%). Sodium fusidate ointment (98%) was significantly better (p less than 0.05) than mupirocin (82%) in patients with other superficial infections. Both ointments were equally effective in cases where Gram-positive, Gram-negative or mixed Gram-positive/Gram-negative bacteria were isolated. Adverse effects were reported in 1.0% of patients using sodium fusidate ointment and in 7.4% of patients using mupirocin ointment. The majority of complaints concerned the greasiness of mupirocin ointment.
Insights
Sodium fusidate ointment and mupirocin ointment showed similar effectiveness for most superficial skin infections. Sodium fusidate was superior for other superficial infections and had fewer adverse effects, primarily related to greasiness.
Area of Science:
- Dermatology
- Infectious Diseases
- Pharmacology
Background:
- Superficial skin infections are common and require effective topical antimicrobial treatment.
- Sodium fusidate and mupirocin are frequently used antibiotics for these conditions.
- Comparative data on their efficacy and tolerability is essential for clinical decision-making.
Purpose of the Study:
- To compare the clinical efficacy and safety of sodium fusidate ointment versus mupirocin ointment in patients with superficial skin sepsis.
- To evaluate treatment outcomes based on infection type (primary, secondary, other) and bacterial etiology.
Main Methods:
- A clinical trial involving 354 patients with superficial skin sepsis.
- Patients received either sodium fusidate or mupirocin ointment, applied 3 times daily or once daily with dressing.
- Treatment response was assessed after 6 to 8 days.
Main Results:
- Both ointments achieved an overall clinical response rate of 86%.
- Efficacy was comparable for primary and secondary skin infections, including impetigo.
- Sodium fusidate demonstrated significantly higher efficacy (98% vs. 82%) in 'other superficial infections'.
- Adverse effects were significantly lower with sodium fusidate (1.0%) compared to mupirocin (7.4%), with greasiness being a common complaint for mupirocin.
Conclusions:
- Sodium fusidate and mupirocin are both effective for common superficial skin infections.
- Sodium fusidate offers an advantage in treating 'other superficial infections' and exhibits a better safety profile.
- The lower incidence of adverse effects, particularly greasiness, makes sodium fusidate a potentially more tolerable option.
