The present invention relates to a stable etanercept aqueous preparation comprising creatinine and/or macrogol 400 as the stabilizer. Decomposition and aggregation of the etanercept can be prevented by adding these stabilizers to the aqueous preparation.本發明係關於含有肌酸酐(creatinine)及/或聚乙二醇(macrogol)(400)作為安定化劑之安定融合蛋白(etanercept)水性製劑。藉由於水性製劑中含有該等安定化劑可防止融合蛋白之分解或凝聚。
