How Do Aminoglycosides Work?

Aminoglycosides are broad-spectrum antibiotics used to treat infections caused by gram-negative aerobic bacilli. While less common, aminoglycosides (in combination with other drugs) have also been used for select gram-positive infections. They are typically administered intravenously, while some can be taken orally.

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. This subsequently leads to the interruption of normal bacterial protein synthesis and results in the formation of an incorrect protein, which may damage the cell membrane. The damaged cell membrane allows an increased amount of drug to enter the bacteria, eventually leading to its death.

How Are Aminoglycosides Used?

Aminoglycosides are mainly used in the treatment of aerobic gram-negative bacilli infections. They are also effective in treating other bacterial infections, including:
