Abstract

The invention relates to the field of Chinese herbal preparations and particularly relates to a rhizoma alismatis dropping pill and a preparation method thereof. The technical scheme is as follows: the invention provides the preparation method of the rhizoma alismatis dropping pill, and the method comprises the following steps of: 1, smashing a rhizoma alismatis raw material, extracting the raw material by using ethanol, absorbing the raw material by using macroporous adsorption resin, eluting the raw material by using ethanol, carrying out vacuum concentration until the raw material becomes an extract to obtain a rhizoma alismatis extract, and mixing the rhizoma alismatis extract with a matrix to form a mixture A, wherein the matrix is polyethylene glycol 4000 or polyethylene glycol 6000 or a mixture of the polyethylene glycol 4000 and the polyethylene glycol 6000, and the weight ratio of the rhizoma alismatis raw material to the matrix is 1:4; and 2, heating the mixture A in the step 1 to obtain rhizoma alismatis extract and matrix contained meltwater, uniformly mixing the meltwater, and placing the meltwater on a pill dropping machine for preparing the dropping pill. The prepared rhizoma alismatis dropping pill has the beneficial effects of rapid curative effect, high bioavailability, convenience and simplicity in operation of the preparation process, easiness for controlling the process condition and stable quality.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine preparations, in particular to Alisma dripping pills and a preparation method thereof. Background technique [0002] Traditional Chinese medicine dripping pills can meet modern preparations "three effects" (high-efficiency, quick-acting, long-acting), "three small" (low toxicity, small reaction, small dosage), "five conveniences" (production, transportation, use, carrying, etc.) , safekeeping) and other advantages are accepted by the people. Moreover, with the accelerated pace of modern life, patients have higher and higher demand for dosage forms. Traditional dosage forms can no longer meet the requirements. The development of traditional Chinese medicine preparations is a historical trend. Dropping Pills just adapted to this trend, opened up a new path for traditional Chinese medicine formulations with its unique advantages, and changed the world's prejudice against traditional Chine...
