How Tobramycin Works

Tobramycin works by interfering with the bacteria’s ability to produce essential proteins, which are necessary for their growth and survival.

As an aminoglycoside antibiotic, it binds to bacterial ribosomes, disrupting protein synthesis.

This action helps to stop the spread of the infection and allows the body’s immune system to eliminate the bacteria.
