Despite the narrow therapeutic window characteristic of amikacin, this amino glycoside remains one of the most frequently prescribed particularly against multiple drug-resistant pathogens. In order to achieve an effective antibiotic therapeutic effect with minimal toxicity and, simultaneously avoid bacterial resistance development, the pharmacokinetics drug monitoring is recommended for amikaci...
OBJECTIVE The purpose of this study was to determine the synergistic activity of amikacin/ertapenem, fluoroquinolones (ciprofloxacin and levofloxacin)/ertapenem and amikacin/fluoroquinolones combinations against resistant nosocomial pathogens. METHODS Time-kill studies were performed over 24 hours using an inoculum of 5 x 10(6) - 1 x 10(7) cfu/mL. Antibiotics were tested at the 1 x MIC and 4 ...
OBJECTIVES This study examined the phenomenon of heteroresistance in Mycobacterium tuberculosis clinical isolates obtained from retreated patients in Beijing, China between 2006 and 2011. METHODS The iPLEX Gold assay platform was used to determine the prevalence of heteroresistance to injectable second-line drugs (amikacin, kanamycin and capreomycin) in resistant isolates. RESULTS Heterores...
The antimicrobial activity of kanamycin, kanendomycin, gentamicin, amikacin, sisomicin, and dibekacin against 200 strains of Pseudomonas aeruginosa was compared. Dibekacin was found to be the most active against the tested organisms, whereas the other aminoglycoside antibiotics fell in the following order of diminishing antibacterial potency: amikacin, sisomicin, gentamicin, kanendomycin, and k...
Background and Objectives: The most common problems limiting the medical use of aminoglycosides have been the nephro- and oto-toxicities as well as the increasing bacterial resistance. Encapsulation of drugs into liposomes enhances their efficacy while reducing their toxicities. The aim of this study was to evaluate the antimicrobial activity of free and liposomal amikacin. Material and Metho...
Amikacin has been one of the important antimicrobial agents against Gram-negative pathogens. However, there is discrepancy regarding the amikacin initial dosage, with some reports recently recommending ≥25 mg/kg and others the conventional dosage (15-20 mg/kg). Hence, we evaluated the optimal initial dosing regimen of amikacin. Pharmacokinetic (PK) parameters were estimated using a population P...
Twenty-six clinical isolates of Mycobacterium abscessus resistant to amikacin were identified. Most isolates were from patients with posttympanostomy tube placement otitis media or patients with cystic fibrosis who had received aminoglycoside therapy. Isolates were highly resistant (MICs > 1024 microg/mL) to amikacin, kanamycin, gentamicin, tobramycin, and neomycin (all 2-deoxystreptamine amino...
The toxicity of netilmicin was compared with that of amikacin in a randomized, prospective trial in 90 adults with a variety of serious gram-negative infections. There was no instance of antibiotic-related nephrotoxicity in the group given amikacin and only one instance in the group given netilmicin. Cochlear toxicity, as measured by a change in audiogram, occurred in 4/14 (28.5%) of the amikac...
Objective: To test in vitro combination of fusidic acid and amikacin against infections caused by methicillin resistant Staphlococus aureus (MRSA). Methodology: In vitro study conducted in Department of Pharmacology and Microbiology, Dr. Ziauddin Medical University. The duration of study was March 2004February 2005. Antibiotic susceptibility testing was done by Kirby Bauer’s disc diffusion meth...
The main purpose of the present work was studying the biodistribution of amikacin solid lipid nanoparticles (SLNs) after pulmonary delivery to increase its concentration in the lungs for treatment of cystic fibrosis lung infections and also providing a new method for clinical application of amikacin. To achieve this aim, (99m)Tc labelled amikacin was loaded in cholesterol SLNs and after in vitr...
