Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
A drug of last resort (DoLR), also known as a heroic dose, [1] is a pharmaceutical drug which is tried after all other drug options have failed to produce an adequate response in the patient. Drug resistance , such as antimicrobial resistance or antineoplastic resistance , may make the first-line drug ineffective, especially in case of ...
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
Urinary tract infection in pediatric patients is a significant clinical issue, affecting approximately 7% of fevered infants and children. [43] If left untreated, the infection can ascend from the bladder to the kidneys, resulting in acute pyelonephritis, which leads to hypertension , kidney scarring , and end-stage kidney disease .
Urinary tract infections, bacterial prostatitis, community-acquired pneumonia, bacterial diarrhea, mycoplasmal infections, gonorrhea: Nausea (rare), irreversible damage to central nervous system (uncommon), tendinosis (rare) Inhibits the bacterial DNA gyrase or the topoisomerase IV enzyme, thereby inhibiting DNA replication and transcription ...
The recommended intravenous dosage in adults is 500 mg every 6 hours or 1000 mg every 12 hours, with modification to achieve a therapeutic range as needed. The recommended oral dosage in the treatment of antibiotic-induced pseudomembranous enterocolitis is 125 to 500 mg every 6 hours for 7 to 10 days. [53]
Resistance to vancomycin in E. faecalis is becoming more common. [16] [17] Treatment options for vancomycin-resistant E. faecalis include nitrofurantoin (in the case of uncomplicated UTIs), [18] linezolid, quinupristin, tigecycline [15] and daptomycin, although ampicillin is preferred if the bacteria are susceptible. [19]
Vancomycin. Six different types of vancomycin resistance are shown by enterococcus: Van-A, Van-B, Van-C, Van-D, Van-E and Van-G. [4] The significance is that Van-A VRE is resistant to both vancomycin and teicoplanin, [5] Van-B VRE is resistant to vancomycin but susceptible to teicoplanin, [6] [7] and Van-C is only partly resistant to vancomycin.
