General information

Netilmycin is a broad-spectrum antibiotic. It is however not effective in treating anaerobic infections - infections occurring in the absence of oxygen - and is often combined with other antibiotics to extend its spectrum of efficacy.

Netilmycin 'teams up ' favourably with penicillin antibiotics; penicillin weakens bacterial cell walls, thereby granting netilmycin access into bacterial cells.

This antibiotic is poorly absorbed when taken by mouth and is generally only used as injection.

Netilmycin is effective in treating infections of the lungs, urinary tract, bones and joints, soft tissue, intra-abdominal infections, meningitis and septicaemia caused by organisms sensitive to netilmycin.

It is important to note that this medication is only effective against bacterial infections - if your infection is the result of a viral or fungal infection, it will be ineffective.

Netilmycin has a very narrow margin of safety, meaning that the toxic concentration of this drug is only slightly higher than its therapeutic dose.

The toxicity of this, and other similar antibiotics, may have severe effects on the ears - this may include permanent hearing loss, balance disturbances and/or ringing in the ears. If it is injected, use should be reserved for severe infections and patients should be monitored closely, while treatment should be for as short a period as possible.

How does netilmycin work?

Netilmycin is part of the aminoglycoside group of bacteria. It kills bacteria as a result of abnormal protein production in the bacterial cell - it cannot produce any of its proteins correctly - and also as a result of damage to the bacterial cell membrane.
