When to use Gentamicin in EENT?
Topical treatment of superficial bacterial infections of the eye caused by susceptible bacteria
Mild, acute bacterial conjunctivitis often resolves spontaneously without anti-infective treatment. Although topical ophthalmic anti-infectives may shorten time to resolution and reduce severity and risk of complications, avoid indiscriminate use of topical anti-infectives
When to use gentamicin together with a corticosteroid?
Fixed-combination ophthalmic preparations containing gentamicin and a corticosteroid (i.e., prednisolone): Topical treatment of corticosteroid-responsive ocular conditions when a corticosteroid indicated and superficial bacterial ocular infection or risk of such infection exists
What is the mechanism of action of gentamicin?
Usually bactericidal
Mechanism of action not fully elucidated; appears to inhibit protein synthesis in susceptible bacteria by irreversibly binding to 30S ribosomal subunits
What is the spectrum of gentamicin?
Spectrum of activity of gentamicin includes many aerobic gram-negative and some aerobic gram-positive bacteria. Inactive against fungi, viruses, and most anaerobic bacteria
Gram-positive bacteria: Active in vitro against Staphylococcus aureus, S. epidermidis, Streptococcus pneumoniae, and S. pyogenes.
Gram-negative bacteria: Active in vitro against Haemophilus influenzae, Enterobacter aerogenes, Escherichia coli, Klebsiella pneumoniae, Neisseria gonorrhoeae, Serratia marcescens, and Pseudomonas aeruginosa
In what bacteria you can find natural and acquired resistance to gentamicin?
in both gram-negative and gram-positive bacteria
What is a contraindication for gentamicin?
Hypersensitivity to gentamicin or any ingredient in the formulation
