It is an object of the present invention to provide the injectable formulation of the stable storing comprising following compositions, the composition includes the insoluble drug and dispersion medium as active constituent. Another object of the present invention is to provide compact, light pre-filled syringe by loading syringe with the injectable formulation. The present invention provides the injectable formulations comprising the composition containing insoluble drug, dispersion medium and specific suspending agent, and when measuring, the composition is 0.01 to 0.Viscosity when at least one of range of shear rate of 02s-1 point is 40 Pascal-seconds or higher, and the viscosity at least one of 900 to 1000s-1 range of shear rate point is 0.2 Pascal-seconds are lower.本發明的一個目的是提供包含下述組合物的儲存穩定的可注射製劑，所述組合物包含作爲活性成分的難溶性藥物和分散媒介。本發明的另一個目的是通過用所述可注射製劑裝填注射器來提供緊凑、輕便的預裝填注射器。本發明提供了包含含有難溶性藥物、分散媒介和特定助懸劑的組合物的可注射製劑，進行測量時，所述組合物在0.01至0.02s‑1的剪切速率範圍中的至少一個點時的黏度爲40帕斯卡‑秒或更高，並且在900至1000s‑1的剪切速率範圍中的至少一個點時的黏度爲0.2帕斯卡‑秒或更低。
