How Gentamicin works
Gentamicin works by stopping bacteria from producing the proteins they need to grow and multiply.
It binds to a part of the bacterial ribosome, the structure responsible for building proteins, and causes errors in protein production.
These errors weaken the bacterial cell and prevent it from functioning normally, leading to its destruction. Gentamicin is particularly effective against certain types of bacteria that cause serious infections, and is often used for infections that require injectable or closely monitored treatment.
