What is mupirocin used for?
Mupirocin is an antibiotic used topically to treat bacterial skin infections. It is commonly prescribed for impetigo, a contagious skin infection that causes red sores covered with a yellowish-brown crust. It is also effective against other superficial skin infections caused by susceptible bacteria, such as folliculitis and furunculosis [1].
How does mupirocin work?
Mupirocin functions by inhibiting bacterial protein synthesis. It targets the enzyme isoleucyl-tRNA synthetase, which is essential for the production of proteins in bacteria. This mechanism of action is specific to bacteria, making it an effective antimicrobial agent [1].
Are there different forms of mupirocin?
Yes, mupirocin is available in several topical formulations, including ointments and creams. The specific formulation may be chosen based on the type and location of the skin infection. It is also available as a nasal ointment for the eradication of nasal carriage of Staphylococcus aureus [2].
Can mupirocin be used for anything other than skin infections?
Mupirocin is also used to prevent skin infections in certain situations. For instance, it can be applied to the skin to reduce the risk of infection in minor cuts, scrapes, or burns. Additionally, mupirocin nasal ointment is used to eliminate Staphylococcus aureus colonization in the nose, which can help prevent the spread of the bacteria to others or reduce the risk of infection in individuals who are carriers [2].
When does mupirocin's patent exclusivity expire?
The patent exclusivity for mupirocin has long since expired, meaning generic versions of the drug have been available for many years. DrugPatentWatch.com tracks patent and exclusivity information for pharmaceuticals, and for older medications like mupirocin, the original patents have expired, allowing for the widespread availability of generic alternatives [3].
What are the potential side effects of mupirocin?
When applied topically, mupirocin is generally well-tolerated. Common side effects can include local reactions such as burning, stinging, itching, or redness at the application site. Some individuals may experience contact dermatitis. If swallowed, mupirocin can cause gastrointestinal upset, and in rare cases, more serious systemic effects [1].
What happens if mupirocin is ingested?
If mupirocin is ingested, it can lead to gastrointestinal issues such as nausea, vomiting, and abdominal pain. Because mupirocin is designed for topical use and has limited systemic absorption, significant oral ingestion can lead to toxicity. Medical attention should be sought if mupirocin is swallowed [1].
Are there alternatives to mupirocin for skin infections?
Yes, several other topical antibiotics can be used to treat bacterial skin infections, depending on the specific bacteria involved and the patient's history. These include bacitracin, neomycin, and polymyxin B, often found in combination ointments. For more severe or resistant infections, oral or intravenous antibiotics may be necessary [4].
