Gentamicin is a powerful intravenous antibiotic used for treating septicaemia, meningitis and other serious infections.

Researchers have produced an experimental form of gentamicin in which the drug is encapsulated in fatty particles called liposomes. This liposomal gentamicin is being tested in combination with other drugs for the treatment of Mycobacterium avium intracellulare (MAI). It is administered by intravenous injection.

One person with MAI in a study of high-dose liposomal gentamicin developed reversible kidney failure, but no other side-effects have been seen.

Gentamicin is a member of the aminoglycoside class of drugs. The codename for liposomal gentamicin is TLC G-65.
