The present invention relates to a kind of Chinese materia medica preparations, it particularly relates to a kind of Radix Astragali broken wall preparation. Invention further passes through alcohol-water wet granulation, and the extrusion forming under certain revolving speed, the universe is dry, thus obtained Radix Astragali broken wall preparation bioavailability with higher, and preparation stability is strong, disintegration is good by the way that Radix Astragali is crushed into superfine powder.本發明涉及一種中藥製劑,具體來說,涉及一種黃芪破壁製劑。發明通過將黃芪粉碎成爲超細粉體,再進一步通過乙醇‑水濕法製粒,並在一定的轉速下擠壓成型,乾燥,由此製得的黃芪破壁製劑具有較高的生物利用率,並且製劑穩定性强、崩解性好。
