Linezolid
Summary
Linezolid is used to treat serious bacterial infections, including pneumonia, which is a lung infection, and skin infections. It is particularly effective against resistant bacteria like MRSA, which is a type of bacteria that does not respond to many antibiotics.
Linezolid works by stopping the growth of bacteria. It does this by inhibiting bacterial protein synthesis, which is the process bacteria use to make proteins they need to survive and multiply.
The usual dose of Linezolid for adults is 600 mg taken twice daily, every 12 hours, for 10 to 14 days. It is taken orally, which means by mouth, and can be taken with or without food.
Common side effects of Linezolid include diarrhea, which is frequent loose or watery stools, headache, and nausea, which is the feeling of wanting to vomit. These effects are usually mild and temporary.
Linezolid can cause serotonin syndrome, which is a serious condition with symptoms like confusion and increased heart rate, when taken with certain antidepressants. It can also cause bone marrow suppression, which affects blood cell production, requiring regular blood tests.
Indications and Purpose
How does Linezolid work?
Linezolid works by inhibiting bacterial protein synthesis, which is essential for bacteria to grow and multiply. It binds to a part of the bacterial ribosome, which is like a factory that makes proteins. By blocking this process, Linezolid stops the bacteria from producing proteins they need to survive. This action helps treat infections by reducing the number of bacteria in the body. Linezolid is effective against certain resistant bacteria, making it a valuable treatment option.
