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.
Do aminoglycosides cause seizures?
aminoglycosides can cause seizures at therapeutic concentrations. c. patients with meningitis have a tendency to be more susceptible to the nephrotoxic effects of the aminoglycosides.
What drug is a fluoroquinolone?
Fluoroquinolones are a class of antibiotics approved to treat or prevent certain bacterial infections. The fluoroquinolone antibiotics include ciprofloxacin (Cipro), gemifloxacin (Factive), levofloxacin (Levaquin), moxifloxacin (Avelox), and ofloxacin (Floxin).
Why is aminoglycosides given orally?
Neomycin is used orally to treat hepatic encephalopathy. Because it is poorly absorbed orally, neomycin causes a decrease in intestinal bacteria, thereby decreasing ammonia production and absorption from the colon.
Do aminoglycosides cross placenta?
The aminoglycosides cross the placenta (4) and their con- centration in the amniotic fluid ranges from 30% to 60% of the average maternal concentration in blood. Severe intrauterine otological damage has been reported after the administration of aminoglycosides to mothers (5).
Is amikacin a strong antibiotic?
Amikacin is an antibiotic medication used for a number of bacterial infections. This includes joint infections, intra-abdominal infections, meningitis, pneumonia, sepsis, and urinary tract infections. It is also used for the treatment of multidrug-resistant tuberculosis.
