Neuromuscular block gentamicin

Antibiotics aminoglycosides, e.g. neomycin, gentamicin, potentiate neuromuscular blocking drugs. 

Neomycin is particularly ototoxic and nephrotoxic when given parenterally. As with gentamicin and kanamycin, the nephrotoxicity may be reversible but the ototoxicity is usually irreversible and deafness may occur following oral administration, instillation into cavities, or topical use. It may block neuromuscular action and respiratory depression has been reported. Local treatments may cause hypersensitivity, rashes, pruritus, and anaphylaxis. Neomycin is not geno-toxic.
