    • A basal insulin formulation composed of insulin (preferably human recombinant insulin), buffering agents, precipitating agents, and/or stabilizing agents for subcutaneous, intradermal or intramuscular administration. In one embodiment, the formulation is designed to form a precipitate of insulin following injection, creating a slow releasing "basal insulin" over a period of 12 to 24 hours. In one embodiment, the insulin formulation is prepared as a suspension for subcutaneous or intramuscular injection at neutral pH (e.g. pH 7), containing human recombinant insulin, a zinc compound, preferably zinc chloride, and a pH buffering agent, preferably sodium acetate. The suspension contains precipitated insulin particles prior to injection and provides a sustained release basal insulin profile following injection.
    • 由胰岛素(优选人重组胰岛素),缓冲剂,沉淀剂和/或用于皮下,皮内或肌内给药的稳定剂组成的基础胰岛素制剂。 在一个实施方案中,将该制剂设计成在注射后形成胰岛素沉淀物,在12至24小时的时间段内产生缓慢释放的“基础胰岛素”。 在一个实施方案中,胰岛素制剂制备为用于在含有人重组胰岛素,锌化合物,优选氯化锌和pH缓冲剂,优选乙酸钠的中性pH(例如pH 7)下皮下或肌内注射的悬浮液。 注射前悬浮液含有沉淀的胰岛素颗粒,并在注射后提供持续释放的基础胰岛素分布。
