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.
Vancomycin activity is considered time-dependent; that is, antimicrobial activity depends on how long the serum drug concentration exceeds the minimum inhibitory concentration of the target organism. Thus, peak serum levels have not been shown to correlate with efficacy or toxicity; indeed, concentration monitoring is unnecessary in most cases.
Time for Timer is a series of seven short public service announcements broadcast on Saturday mornings on the ABC television network starting in 1975. The animated spots feature Timer, a tiny cartoon character who is an anthropomorphic circadian rhythm , the self-proclaimed "keeper of body time."
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
[10] [11] It is used either by injection into a vein or by mouth. [10] When given for short periods, linezolid is a relatively safe antibiotic. [12] It can be used in people of all ages and in people with liver disease or poor kidney function. [10] Common side effects with short-term use include headache, diarrhea, rash, and nausea. [10]
It belongs to the same class as vancomycin, the most widely used and one of the treatments available to people infected with methicillin-resistant Staphylococcus aureus (MRSA). [ 7 ] Dalbavancin is a semisynthetic lipoglycopeptide that was designed to improve upon the natural glycopeptides vancomycin and teicoplanin . [ 8 ]
The antibiotic vancomycin was first isolated from the bacteria in 1953. [4] [5] References This page was last edited on 17 August 2023, at 02:05 (UTC). ...
They require only short contact time, and are most effective against susceptible bacterial populations that are rapidly multiplying. [8] These activities are attributed to a primary mode of action as protein synthesis inhibitors , though additional mechanisms are implicated for some specific agents, and/or thorough mechanistic descriptions are ...
