Pharmacology
Gentamicin is an aminoglycoside antibiotic and has a bactericidal action against many Gram-negative and some strains of Gram-positive bacteria. After actively transporting across the bacterial cell membrane, Gentamicin binds to a specific receptor protein on the 30S subunit of bacterial ribosomes, and interferes with protein synthesis. Hydrocortisone depresses formation, release, and activity of endogenous mediators of inflammation as well as modifying immune response.
Mechanism of action
Gentamicin inhibits bacterial protein synthesis to control infection and Hydrocortisone reduces inflammation, redness and itching.
