| DrugBank Description: | Linezolid is a synthetic antibiotic which is used for the treatment of infections caused by aerobic Gram-positive bacteria. Its effects are bacteriostatic against both enterococci and staphylococci and bactericidal against most isolates of streptococci. Linezolid exerts its antibacterial activity by inhibiting the initiation of bacterial protein synthesis - more specifically, it binds to the 23S ribosomal RNA of the 50S subunit and, in doing so, prevents the formation of the 70S initiation complex which is essential for bacterial reproduction. Linezolid was initially approved in 2000 and was the first member of the oxazolidinone antibiotic class. A second member of this class, , was approved by the FDA in 2014 and is considered generally more effective and tolerable than its predecessor. |
| CAS Number: | 165800-03-3 |
| Molecular Weight: | 337.3461 |
| DrugBank Indication: | Linezolid is indicated in adults and children for the treatment of infections caused by susceptible Gram-positive bacteria, including nosocomial pneumonia, community-acquired pneumonia, skin and skin structure infections, and vancomycin-resistant _Enterococcus faecium_ infections. Examples of susceptible bacteria include _Staphylococcus aureus_, _Streptococcus pneumoniae_, _Streptococcus pyogenes_, and _Streptococcus agalactiae_. Linezolid is not indicated for the treatment of Gram-negative infections, nor has it been evaluated for use longer than 28 days. |
| DrugBank Pharmacology: | Linezolid is an oxazolidinone antibacterial agent effective against most strains of aerobic Gram-positive bacteria and mycobacteria. It appears to be bacteriostatic against both staphylococci and enterococci and bactericidal against most isolates of streptococci. Linezolid has shown some _in vitro_ activity against Gram-negative and anaerobic bacteria but is not considered efficacious against these organisms. Linezolid is a reversible and non-selective inhibitor of monoamine oxidase (MAO) enzymes and can therefore contribute to the development of serotonin syndrome when administered alongside serotonergic agents such as selective serotonin re-uptake inhibitors (SSRIs) or tricyclic antidepressants (TCAs). Linezolid should not be used for the treatment of catheter-related bloodstream infections or catheter-site infections, as the risk of therapy appears to outweigh its benefits under these circumstances. |
| DrugBank MoA: | Linezolid exerts its antibacterial effects by interfering with bacterial protein translation. It binds to a site on the bacterial 23S ribosomal RNA of the 50S subunit and prevents the formation of a functional 70S initiation complex, which is essential for bacterial reproduction, thereby preventing bacteria from dividing. Point mutations in the bacterial 23S rRNA can lead to linezolid resistance, and the development of linezolid-resistant _Enterococcus faecium_ and _Staphylococcus aureus_ have been documented during its clinical use. As antimicrobial susceptibility patterns are geographically distinct, local antibiograms should be consulted to ensure adequate coverage of relevant pathogens prior to use. |

| I01 | 552 | Pneumonia | A lung disease that involves lung parenchyma or alveolar inflammation and abnormal alveolar filling with fluid (consolidation and exudation). It results from a variety of causes including infection with bacteria, viruses, fungi or parasites, and chemical or physical injury to the lungs. It is accompanied by fever, chills, cough, and difficulty in breathing. http://en.wikipedia.org/wiki/Pneumonia | disease of anatomical entity/respiratory system disease/ lower respiratory tract disease/lung disease | Details |
