Netilmicin (1-N-ethylsisomicin) is a semisynthetic aminoglycoside antibiotic, and a derivative of sisomicin, produced by Micromonospora inyoensis. Aminoglycoside antibiotics have the ability to kill a wide variety of bacteria. Netilmicin is not absorbed from the gut and is therefore only given by injection or infusion. It is only used in the treatment of serious infections particularly those resistant to gentamicin.

It was patented in 1973 and approved for medical use in 1981.[2] It was approved for medical use in the UK in December 2019, for the treatment of external infections of the eye.[3] It is on the World Health Organization's List of Essential Medicines.[4]

Comparison with drugs

According to the British National Formulary (BNF), netilmicin has similar activity to gentamicin, but less ototoxicity in those needing treatment for longer than 10 days. Netilmicin is active against a number of gentamicin-resistant Gram-negative bacteria but is less active against Pseudomonas aeruginosa than gentamicin or tobramycin.[citation needed]
