How Dexamethasone + Gatifloxacin works
Dexamethasone, the corticosteroid in this combination, latches onto glucocorticoid receptors in the body. This action blocks the production of substances that cause inflammation such as prostaglandins and leukotrienes. This action helps reduce redness, swelling, and itchiness in the eyes.
Gatifloxacin, the antibiotic part, interferes with two vital enzymes in bacteria called DNA gyrase and topoisomerase IV. This disruption interferes with the bacteria's ability to replicate its DNA and divide, leading to the death of bacterial cells.
