Mechanism Steps

1Neomycin binds to 30S ribosomal subunit of bacteria, inhibiting protein synthesis
2Dexamethasone binds to glucocorticoid receptors, inhibiting phospholipase A2
3Reduced arachidonic acid release decreases prostaglandin and leukotriene synthesis
4Decreased inflammation and immune response
