Clinical Matrix

Mechanism of Action

Gentamicin is an aminoglycoside antibiotic that binds to the 30S ribosomal subunit, causing misreading of mRNA and inhibition of protein synthesis, leading to bacterial cell death.

Neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, causing misreading of mRNA and cell death. Dexamethasone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.

Clinical Dosing

Gentamicin 3-5 mg/kg/day IV or IM in 3 divided doses every 8 hours for serious infections; may use once-daily dosing (5 mg/kg IV every 24 hours) for certain indications.

1-2 drops of ophthalmic solution (neomycin 3.5 mg/mL and dexamethasone 1 mg/mL) or ointment (neomycin 3.5 mg/g and dexamethasone 1 mg/g) into the affected eye(s) every 4-6 hours; in severe cases, every 1-2 hours initially and tapered. For otic use: 3-4 drops into the affected ear(s) 3-4 times daily. Topical: apply thin layer to affected area 1-3 times daily.
