The capsule drug ring (CDR) is a reservoir and delivery agent, which is designed to be placed within the capsular bag during cataract surgery. Prototypes were manufactured by hot melt extrusion of Bionate II®, a polycarbonate urethane. The devices have been optimized using Avastin® as the drug of interest. In vitro biocompatibility was assessed with human lens epithelial cell (B-3), mouse macrophage (J774A.1) and mouse fibroblast (L-929) cell lines. Cell migration and proliferation were assessed after in vitro culture. Pro-inflammatory cytokines (i.e., MIP-1β, MIP-1α, MCP-1, IL-1β, TNF and TGF-β1) were quantified using cytometric bead array (CBA). Preliminary in vivo biocompatibility and pharmacokinetics testing has been performed in rabbits.
胶囊药物环（CDR）是一种储库和递送剂，设计用于在白内障手术期间放置在晶状体囊袋内。原型通过热熔融挤出聚碳酸酯聚氨酯Bionate II®制造。这些装置已使用阿瓦斯汀®作为目标药物进行了优化。使用人晶状体上皮细胞（B - 3）、小鼠巨噬细胞（J774A.1）和小鼠成纤维细胞（L - 929）细胞系评估体外生物相容性。体外培养后评估细胞迁移和增殖。使用细胞计数珠阵列（CBA）对促炎细胞因子（即MIP - 1β、MIP - 1α、MCP - 1、IL - 1β、TNF和TGF - β1）进行定量。已在兔子身上进行了初步的体内生物相容性和药代动力学测试。
