OZURDEX Intravitreal implant containing dexamethasone 0.7 mg in the NOVADUR solid polymer drug delivery system.
OZURDEX is an intravitreal implant containing 0.7 mg (700 μg) dexamethasone in the NOVADUR solid polymer drug delivery system. OZURDEX is preloaded into a single-use, specially designed DDS applicator to facilitate injection of the rod-shaped implant directly into the vitreous. The NOVADUR system contains poly (D,L-lactide-co-glycolide) PLGA intravitreal polymer matrix. OZURDEX is preservative-free. The chemical name for dexamethasone is pregna-1,4-diene-3,20-dione, 9-fluoro-11,17,21-trihydoxy-16-methyl-,(11 β,16α). Its MW is 392.47; molecular formula: C22H29FO5.
Dexamethasone occurs as a white to cream-colored crystalline powder having not more than a slight odor, and is practically insoluble in water and very soluble in alcohol. The PLGA matrix slowly degrades to lactic acid and glycolic acid.
