Problems solved by technology

[0003] At present, there are many problems in the preparation of Zhenju Jiangya Tablets: ① Yechrysanthemum cream powder is easy to absorb moisture and is not easy to granulate. In order to reduce the viscosity of granules, a higher concentration of ethanol is generally used for granulation, which not only increases the cost, but also is not conducive to granulation. Labor protection; ②The preparation is easy to absorb moisture during storage, resulting in slower tablet disintegration; ③Poor compressibility of nacre powder, easy to produce loose tablets

Abstract

The invention discloses a rapidly-dissolved Zhenju antihypertension tablet and a preparation process thereof. The preparation contains copovidone and polacrilin potassium. The preparation process comprises the following steps: (1) placing the copovidone into pure water, stirring the pure water until the copovidone is dissolved, then adding hydrochlorothiazide and clonidine hydrochloride, and stirring until the hydrochlorothiazide and clonidine hydrochloride are dissolved for standby use; (2) weighing wild chrysanthemum flower cream powder, pearl layer powder, rutin and polacrilin potassium, filtering and uniformly mixing to obtain a mixture, spraying a mixed solution prepared in the step (1) by adopting a fluidized bed spray method, and carrying out the granulation and drying; and (3) weighing dry particles prepared in the step (2), adding the lubricating agent, uniformly mixing, and tabletting. The rapidly-dissolved Zhenju antihypertension tablet is good in compressibility, rapid to disintegrate and high in dissolution rate and has the advantages of simple preparation process and easiness in operation.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a Zhenju Jiangya tablet with rapid disintegration and dissolution and a preparation process thereof. Background technique [0002] Zhenju Jiangya Tablet is a compound antihypertensive preparation of traditional Chinese medicine and western medicine, which consists of 100mg of wild chrysanthemum cream powder, 100mg of nacre powder, 0.03mg of clonidine hydrochloride, 5mg of hydrochlorothiazide, 20mg of rutin and pharmaceutical excipients. Among them, wild chrysanthemum is bitter, pungent, and slightly cold in nature, and belongs to the lung and liver meridian. It has the functions of clearing away heat and expelling wind, calming the liver and lowering blood pressure. Oxygen consumption, improving myocardial ischemia, etc., it expands peripheral blood vessels by inhibiting sympathetic nerve and vasomotor center, reduces total peripheral resistance, a...
