Chloramphenicol BP + Dexamethasone Sodium Phosphate BP
|0.5% w/v + 0.1% w/v
Chloramphenicol is a true broad spectrum antibiotic. It is active against a wide range of gram-positive and gram-negative bacteria, many anaerobic bacteria, chlamydia and rickettsia. It is usually bacteriostatic but may be bactericidal in high concentrations. Antibiotic activity appears to result from inhibition of protein synthesis of bacterial cells. Chloramphenicol binds to the 50s subunit of bacterial ribosomes, which inhibits peptide bond formation. The protein synthesis of rapidly proliferating cells may be affected, especially mammalian erythrocytes, explaining the mechanism of reversible bone marrow depression. Dexamethasone is one of the most potent corticosteroids; it is 5-14 times more potent than Prednisolone and 25 - 75 times more potent than Cortisone and Hydrocortisone. A paramount importance with regard to local therapy is the fact that Dexamethasone is over 2000 times more soluble than Hydrocortisone or Prednisolonc. Like all other glucocorticoids, Dexamethasone inhibits phospholypase A, the first step in prostaglandin synthesis. Also, Dexamethasone inhibits the chcmotactic infiltration by inhibiting endothelial expression of adhesion molecules for neutrophils.
