The present invention relates to a kind of Chinese materia medica preparations, it particularly relates to a kind of lamiophlomis rotata broken wall preparation. Invention is by being crushed into superfine powder for lamiophlomis rotata, further by alcohol-water wet granulation, and the extrusion forming under certain revolving speed, the universe are dry, thus obtained lamiophlomis rotata broken wall preparation bioavailability with higher, and preparation stability is strong, disintegration is good.本發明涉及一種中藥製劑，具體來說，涉及一種獨一味破壁製劑。發明通過將獨一味粉碎成爲超細粉體，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，由此製得的獨一味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。
