Injectable compositions having improved injectability. The injectable compositions include microparticles in an aqueous injection vehicle having a viscosity of at least 20 cp at 20 °C. The increased viscosity of the injection vehicle that constitutes the fluid phase of the suspension significantly reduces in vivo injectability failures. The injectable compositions can be made by mixing dry microparticles with an aqueous injection vehicle to form a suspension, and then mixing the suspension with a viscosity enhancing agent to increase viscosity of the fluid phase of the suspension to the desired level for improved injectability.
注射剂组合物具有更好的可注射性。可注射组合物包括
水性注射载体中的微颗粒,该注射载体在 20 °C 时的粘度至少为 20 cp。构成悬浮液液相的注射载体粘度增加,可显著降低体内注射失败率。可注射组合物可通过将干微颗粒与
水性注射载体混合形成悬浮液,然后将悬浮液与增粘剂混合,以将悬浮液流体相的粘度增加到所需
水平,从而改善可注射性。
