Pharmacology
Moxifloxacin is a broad spectrum 4th generation fluorinated quinolone. It inhibits both topoisomerase II (DNA gyrase) and topoisomerase IV. DNA gyrase is an essential enzyme that is involved in the replication, transcription and repair of bacterial DNA. Topoisomerase IV is an enzyme known to play a key role in the partitioning of the chromosomal DNA during bacterial cell division.
Dexamethasone is a cortisone derivative that shows high activity due to the presence of methyl group in the 16-alpha position and of a fluorine atom in the 9-alpha position. Like other glucocorticoids, it is anti-allergic, anti-exudative and anti-proliferative. The action of Dexamethasone is to inhibit the phospholipase A2, the first step in prostaglandin synthesis. Also, Dexamethasone inhibits the chemotactic infiltration of neutrophils into the site of inflammation.
