Background and Date of Approval
Linezolid was initially approved by the United States Food and Drug Administration (FDA) on 18 April 2000.
Mechanism of Action of undefined
Linezolid's mechanism of action involves attaching to the bacterial ribosome's 23S rRNA, which disrupts the creation of working ribosomal structures necessary for protein production. This interruption slows down the beginning and building phases of protein synthesis, ultimately stopping bacterial growth and reproduction, while human ribosomes remain unaffected due to their different structure.
Uses of undefined
Linezolid is used to treat bacterial infections caused by susceptible gram-positive bacteria, particularly in cases where other antibiotics might be ineffective due to bacterial resistance. Common applications include treating infections like methicillin-resistant staphylococcus aureus (MRSA) infections, vancomycin-resistant enterococcus (VRE) infections, pneumonia, skin and soft tissue infections, and other serious infections caused by drug-resistant bacteria.
undefined Drug administaration and Dosage available
Linezolid can be administered orally through tablets or liquid, taken by mouth, or intravenously through infusion into a vein. The choice between these routes depends on the severity of infection, the patient's condition, and guidance by the healthcare provider.

If you have diabetes or high blood pressure, monitoring blood sugar and pressure regularly is necessary. Tyramine-rich foods should be consumed with caution due to potential interactions. Always stick to the prescribed duration and seek medical help in case of emergencies or unexpected reactions.
