Mupirocin ointment is used to treat impetigo, a bacterial skin infection [1]. It is also applied topically to prevent bacterial contamination of minor cuts, abrasions, and burns [1].
What makes mupirocin effective against skin infections?
Mupirocin works by inhibiting bacterial protein synthesis [2]. It targets the enzyme isoleucyl-tRNA synthetase, which is essential for producing proteins in bacteria [2]. This mechanism is specific to bacteria, meaning it does not harm human cells [2].
Can mupirocin be used for other skin conditions?
While its primary use is for impetigo and as a preventative measure for minor wounds, mupirocin can also be prescribed for other bacterial skin infections such as folliculitis, furunculosis, and ecthyma [1]. It is also sometimes used to treat and prevent methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization [3].
How is mupirocin ointment typically prescribed?
Mupirocin ointment is usually applied directly to the affected skin area two to three times a day for a prescribed duration, typically between 7 to 14 days [1]. For nasal application, it is generally used twice daily [3]. It is important to complete the full course of treatment as directed by a healthcare professional to ensure the infection is fully cleared [1].
Are there any side effects associated with mupirocin ointment?
Common side effects may include localized burning, stinging, itching, or redness at the application site [1]. In some cases, headache and nausea have also been reported [1]. Allergic reactions are rare but possible [1].
Where can I find more information on mupirocin's patent status and exclusivity?
