OPHTHOCHLOR vs VASOCIDIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Vasocidin is a combination of sulfacetamide sodium, a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking folate synthesis and bacterial growth, and prednisolone sodium phosphate, a corticosteroid that suppresses inflammation by inhibiting phospholipase A2 and subsequent prostaglandin and leukotriene synthesis.
Chloramphenicol 0.5% ophthalmic solution: Instill 1-2 drops into the affected eye(s) every 3-4 hours for 7-10 days. For severe infections, every 2 hours initially. Ointment: Apply a small amount (about 0.5 cm) into the conjunctival sac every 3-4 hours.
One drop of the ophthalmic suspension into the conjunctival sac of the affected eye(s) every 4 hours while awake and at bedtime for 7 days; duration may be extended based on clinical response.
