Amicacin

Amicacin - General Information

A broad-spectrum antibiotic derived from kanamycin. It is reno- and oto-toxic like the other aminoglycoside antibiotics.

 

Pharmacology of Amicacin

Amicacin is an aminoglycoside antibiotic. Aminoglycosides work by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Aminoglycosides are useful primarily in infections involving aerobic, Gram-negative bacteria, such as Pseudomonas, Acinetobacter, and Enterobacter. In addition, some mycobacteria, including the bacteria that cause tuberculosis, are susceptible to aminoglycosides. Infections caused by Gram-positive bacteria can also be treated with aminoglycosides, but other types of antibiotics are more potent and less damaging to the host. In the past the aminoglycosides have been used in conjunction with penicillin-related antibiotics in streptococcal infections for their synergistic effects, particularly in endocarditis. Aminoglycosides are mostly ineffective against anaerobic bacteria, fungi and viruses.

 

Amicacin for patients

Patient Information:
Amikacin is potentially nephrotoxic, ototoxic and neurotoxic. Patient should
drink more fluid to minimize the chemical irritation to the kidney. Renal
function should be monitored before and during the course of the treatment.
Amikacin-induced ototoxicity is usually irreversible. Patient may not have any
symptoms. Patient may experience numbness, tingling, muscle twitching and
convultions because of the neurotoxicity.
If patient experiences any unusual signs or symptoms, please contact you doctor
immediately.

Amicacin Contraindications

A history of hypersensitivity to amikacin is a contraindication for its use. A history of hypersensitivity or serious toxic reactions to aminoglycosides may contraindicate the use of any other aminoglycoside because of the known cross-sensitivities of patients to drugs in this class.

 

Additional information about Amicacin

Amicacin Indication: For short-term treatment of serious infections due to susceptible strains of Gram-negative bacteria, including Pseudomonas species, Escherichia coli, species of indole-positive and indole-negative Proteus, Providencia species, Klebsiella-Enterobacter-Serratia species, and Acinetobacter (Mima-Herellea) species.
Mechanism Of Action: Aminoglycosides like Amicacin "irreversibly" bind to specific 30S-subunit proteins and 16S rRNA. Amicacin inhibits protein synthesis by binding to the 30S ribosomal subunit to prevent the formation of an initiation complex with messenger RNA. Specifically Amicacin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex, misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes.
