Which drugs are aminoglycosides?
The aminoglycosides include gentamicin, amikacin, tobramycin, neomycin, and streptomycin. Gentamicin is the most commonly used antibiotic in UK neonatal units.
What is aminoglycoside used for?
Aminoglycosides are used in the treatment of severe infections of the abdomen and urinary tract, as well as bacteremia and endocarditis. They are also used for prophylaxis, especially against endocarditis.
What are two major side effects of aminoglycosides?
The major side effects of aminoglycosides are kidney injury, hearing impairment and vestibular toxicity.
What do aminoglycosides target?
Aminoglycosides are a class of clinically important antibiotics used in the treatment of infections caused by Gram-positive and Gram-negative organisms. They are bactericidal, targeting the bacterial ribosome, where they bind to the A-site and disrupt protein synthesis.
How do aminoglycosides work?
Aminoglycosides act through inhibition of protein synthesis. Once inside the bacterial cell, they bind to the A-site in ribosomal RNA of the 30S subunit and cause a misreading of transfer RNA codons.
Why are aminoglycosides given with other antibiotics?
They are often used in combination with other antibiotics. Aminoglycosides are thought to work by inhibiting protein synthesis inside bacteria.
Is doxycycline an aminoglycoside?
Aminoglycosides are bactericidal against these organisms and the use of bacteriostatic agents, such as doxycycline or chloramphenicol has led to treatment failures (Dennis et al.
Can amikacin be given once daily?
For elderly patients a smaller dose of amikacin than the regular daily dose of 15 mg/kg bw, i.e. about 11 mg/kg bw, seems recommendable, when it is given once daily. From the data obtained it is also obvious that once-daily dosing of amikacin does not eliminate the need for checking serum concentrations of the drug.
Is ampicillin an aminoglycoside?
In the past, the aminoglycosides have been used in conjunction with beta-lactam antibiotics in streptococcal infections for their synergistic effects, in particular in endocarditis. One of the most frequent combinations is ampicillin (a beta-lactam, or penicillin-related antibiotic) and gentamicin.
