  Hypnotic pharmaceutical compositions are made from pellets and exhibit a modified release. Zolpidem or a pharmaceutically acceptable salt thereof is a typical hypnotic. The pellets are preferably spherical and exhibit a dissolution profile that includes 60% of the hypnotic agent being release from the pellet not earlier than 5 minutes from the start of a specified in vitro dissolution test. Although the modified release profile can include 50% of the hypnotic agent being released not earlier than 15 minutes after the start of the dissolution test, the pellet preferably does not contain a release rate controlling excipient or coating. Instead, microcrystalline cellulose and the active constitute the majority of the pellet, e.g. 90% or more. Spherical pellets are also made by a convenient method that is applicable to any pharmaceutically active agent.

  催眠药物组合物是由颗粒制成的，具有改变释放的特性。唑吡坦或其药学上可接受的盐是一种典型的催眠药。颗粒最好是球形的，其溶解曲线包括 60% 的催眠药在指定的体外溶解试验开始后 5 分钟内从颗粒中释放出来。虽然修正后的释放曲线可以包括 50%的催眠药在溶出试验开始后 15 分钟内释放，但颗粒最好不含控制释放速率的赋形剂或涂层。相反，微晶纤维素和活性物质占颗粒的大部分，例如 90% 或更多。球形颗粒也可通过一种适用于任何药物活性剂的便捷方法制成。
