Pharmacology & Mechanism of Action
Levofloxacin is a synthetic third-generation fluoroquinolone anti-bacterial agent that inhibits the supercoiling activity of bacterial DNA gyrase, halting DNA replication. Levofloxacin, the active L-isomer of ofloxacin that inhibits bacterial type II topoisomerases-DNA gyrase and topoisomerase IV. Levofloxacin preferentially targets DNA gyrase in Gram-negative bacteria and topoisomerase IV in Gram-positive bacteria. On the other hand, the action of Dexamethasone Phosphate is to inhibit the phospholipase A 2 , the first step in prostaglandin synthesis. Also, inhibits the chemotactic infiltration of neutrophils into the site of inflammation. Its anti-inflammatory activity is 30 times greater and its overall therapeutic effectiveness 8-10 times greater than that of hydrocortisone. Like other glucocorticoids, it is anti-allergic, anti-exudative & anti-proliferative.
