OZURDEX ® is a sterile intravitreal implant containing 0.7 mg (700 mcg) dexamethasone in the NOVADUR ® solid polymer sustained-release drug delivery system which does not contain an antimicrobial preservative. OZURDEX ® is preloaded into a single-use, DDS ® applicator to facilitate injection of the rodshaped implant directly into the vitreous. The NOVADUR ® system contains two poly D,L-lactide-co-glycolide (PLGA) polymer excipients. Both of these polymer materials have the same PLGA backbone, but the terminal end groups differ between them. One polymer, DL-Lactide and Glycolide (50:50) Copolymer 12000 Ethyl Ester, is ester terminated, and the other DL-Lactide and Glycolide (50:50) Copolymer 12000 Acid is acid terminated. The chemical name for dexamethasone is Pregna-1,4-diene-3,20-dione, 9-fluoro-11,17,21-trihydroxy-16-methyl-, (11β,16α)-. Its structural formula is: MW 392.47; molecular formula: C 22 H 29 FO 5 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.
