Problems solved by technology

Cyclodextrin inclusion process effectively solves the problem of oily drug solidification and preparation of common solid dosage forms, but this process consumes a lot of raw materials, affects the yield, complex operation, and long production process
[0005] In another Chinese patent CN1623542A applied by CSPC Zhongqi Pharmaceutical Technology, a soft capsule preparation of butylphthalide is disclosed. The soft capsule is composed of capsule material and medicinal liquid oil, wherein the medicinal liquid is basically composed of butylphthalide and diluent vegetable oil. Composition, butylphthalide is easy to prepare into soft capsule dosage form, but the disadvantage is that the capsule skin is easily affected by temperature and humidity, and the capsule skin is aging, which affects in vitro dissolution and in vivo absorption
