TobraDex (0.3/0.1mg) 3.5g Eye Ointment

Dexamethasone, a potent synthetic corticosteroid, exerts its anti-inflammatory effects by binding to cytoplasmic glucocorticoid receptors, altering gene expression and suppressing the production of various pro-inflammatory mediators. This inhibits the release of inflammatory substances, reduces capillary permeability, and stabilizes cell membranes, thereby reducing inflammation and associated symptoms. Tobramycin, an aminoglycoside antibiotic, acts by binding to specific receptor sites on the bacterial cell membrane, disrupting protein synthesis. It primarily targets the 30S ribosomal subunit of susceptible bacteria, leading to the misreading of t-RNA, inhibiting protein synthesis, and ultimately causing bacterial cell death. The combination of dexamethasone and tobramycin in an ointment form allows for the simultaneous treatment of inflammation and bacterial infections, providing both therapeutic benefits and potentially reducing treatment duration.
