Abstract

The present invention provides a complete gastrodia tuber soft capsule and a preparation method thereof, which solves the defects of the prior art that the refined gastrodia tuber powder is hardly dissolved in edible oil, easily congregated into particles, delaminated and unevenly dispersed after placement. Calculated by weight portions, the present invention includes the following procedures: taking one portion of gastrodia tuber and grinding the gastrodia tuber into 120 meshes; adding 0.5 to 3 portions of polyglycol400 and propanediol accounting for 8% of the amount of polyglycol400 after sterilization; then evenly mixing, filling and pressing the mixture into soft capsules. Compared with the prior art, the present invention takes polyglycol400 as the diluting agent so that the refined gastrodia tuber powder can be better dispersed. In addition, the present invention has no delamination after placement and excellent stability and can better increase the biological utilization of thesoft capsule preparation. The addition of propanediol into the diluting agent can prevent the soft capsule shell from hardening and the disintegration time limit from prolonging in storage. The complete gastrodia tuber soft capsule has obvious curative effect on headache and dizziness, numb limbs and tense tendons, hieronosus and hyperspasmia and other diseases.

Description

technical field [0001] The invention relates to a whole gastrodia elata preparation and a preparation method thereof, in particular to a whole gastrodia elata soft capsule preparation and a preparation method thereof. Background technique [0002] Gastrodia elata has relatively good curative effect on diseases such as headache, dizziness, limb numbness, but the effect of direct use is not ideal. In the prior art, Gastrodia elata is made into whole Gastrodia elata capsules or Gastrodia elata tablets, but they are only crushed into Gastrodia elata in the production process. The fine powder (fineness is 80-100 meshes), sterilized and filled into capsules or added with appropriate excipients and compressed into tablets. These drugs have relatively poor stability, are easy to absorb moisture, and have low bioavailability and poor effect. [0003] The original dosage form of Gastrodia elata is capsule, because capsule has above-mentioned problem, so the marketability of commodity...
