MRSA can be eradicated with a regimen of linezolid, [87] though treatment protocols vary and serum levels of antibiotics vary widely from person to person and may affect outcomes. [88] The effective treatment of MRSA with linezolid has been successful [87] in 87% of people. Linezolid is more effective in soft tissue infections than vancomycin.
Products used for decolonization typically involve chlorhexidine rinses for bathing or showering, a mouthwash to clean the oral cavity, and a nasal spray containing mupirocin. It is important to include a mouthwash and nasal spray as individuals commonly carry MRSA in the nose, mouth, and throat.
It is a potential treatment for methicillin-resistant Staphylococcus aureus (MRSA) and possibly Clostridioides difficile. It is being developed by Destiny Pharma Ltd. [2] [3] [4] Structurally, it is a dicationic porphyrin. [5] It has completed a phase I clinical trial for nasal decolonisation of MRSA—being tested against 5 bacterial strains.
Delafloxacin has been evaluated in four Phase 2 trials where it has shown promising results for the treatment of lung infections, including pneumonia and bronchitis, and skin infections.
First-line treatment for serious invasive infections due to MRSA is currently glycopeptide antibiotics (vancomycin and teicoplanin). A number of problems with these antibiotics occur, such as the need for intravenous administration (no oral preparation is available), toxicity, and the need to monitor drug levels regularly by blood tests.
Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis. [5] [6] [7] It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms. [6]
A staphylococcal infection or staph infection is an infection caused by members of the Staphylococcus genus of bacteria.. These bacteria commonly inhabit the skin and nose where they are innocuous, but may enter the body through cuts or abrasions which may be nearly invisible.
Although many strains of MRSA remain sensitive to fusidic acid, there is a low genetic barrier to drug resistance (a single point mutation is all that is required), fusidic acid should never be used on its own to treat serious MRSA infection and should be combined with another antimicrobial such as rifampicin when administering oral or topical ...
