Triamcinolone acetonide suspension compositions are disclosed. The suspension compositions have a relatively low viscosity and are easy to extrude through a 27-or 30-guage needle but are highly flocculated and easily redispersed. The compositions are particularly suitable for intravitreal injection.本發明揭示出一種丙酮特安皮質醇懸浮液組成物。該懸浮液組成物具有相當低的黏性且容易擠壓通過27-或30-針規的針,而且其高度絮凝及容易再分散。該組成物特別合適於玻璃狀體內注射。
