4 Drug and Medication Information
4.1 Drug Indication

Arbekacin is used for the short term treatment of multi-resistant bacterial infections, such as methicillin-resistant Staphylococcus aureus (MRSA).


5 Pharmacology and Biochemistry
5.1 Pharmacology

Arbekacin is an aminoglycoside. Aminoglycosides function by binding to bacterial 30S ribosomal subunits, causing t-RNA misreads, and preventing the production of proteins. Anaerobes are less susceptible to aminoglycosides because they do not spend as much energy as aerobes on taking up chemicals like aminoglycosides. Aminoglycosides are useful primarily in infections involving aerobic, gram-negative bacteria, such as Pseudomonas, Acinetobacter, and Enterobacter.


5.2 MeSH Pharmacological Classification

Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)


5.3 ATC Code

J - Antiinfectives for systemic use

J01 - Antibacterials for systemic use

J01G - Aminoglycoside antibacterials

J01GB - Other aminoglycosides

J01GB12 - Arbekacin


5.4 Absorption, Distribution and Excretion

Absorption

Aminoglycosides are not well absorbed from the gastrointestinal tract. Their absorption is markedly improved by parenteral administration.


5.5 Biological Half-Life

3 hours


5.6 Mechanism of Action

Arbekacin irreversibly binds bacterial 30S and 16S ribosomal subunits inhibiting protein synthesis. Arbekacin binds to 4 nucleotides of the 16S subunit and 1 amino acid of protein S12 to interfere with the decoding site around nucleotide 1400 in the 16S subunit. Interference with the decoding site interferes with its interaction with the wobble base of tRNA. This hindered interaction causes mRNA to be misread and the incorrect amino acids are inserted into protein. These error filled proteins are not able to function or may even be toxic.
