Description
Technical field
The invention belongs to technical field of medicine, is disintegrated rapid, Fast Stripping precious chrysanthemum drop in particular to a kind of
Tabletting and its preparation technology.
Background technology
In Zhenju Jiangya Tablet system, Western medicine compound antihypertensive formulation, by chrysanthemum indicum cream powder 100mg, nacreous layer powder 100mg, hydrochloric acid
Clonidine 0.03mg, Hydrochioro 5mg, rutin 20mg and pharmaceutic adjuvant composition.Wherein, chrysanthemum indicum it is bitter in taste, it is pungent, be slightly cold, return
Lung and Liver Channel, have heat-clearing wind-dispelling, soothing the liver buck functionality, and modern study finds that chrysanthemum indicum cream powder has increase coronary flow, drop
Low coronary resistance, reduce myocardial oxygen consumption, improve the effect such as myocardial ischemia, it is by suppressing sympathetic nerve and vasomotor center
And peripheral vascular is expanded, total peripheral resistance is reduced, antihypertensive effect is played to antiadrenergic drug.Pearl nourishing disney and strengthening bone, arresting convulsion of calming the nerves,
Improving eyesight disappears screen, solution taking poison and growing muscle due, and modern study finds that nacreous layer powder contains abundant calcium carbonate and several amino acids, is beneficial to stable
Cardiovascular structure and function, that is, there are calm the nerves arresting convulsion, regulation human body control ability.Clonidine hydrochloride is set to the sympathetic god of central
Inhibited medicine, there is preferable antihypertensive effect, and have certain effect for reducing fat, but use can decline glomerular filtration rate(GFR long, cause water
Sodium retention, Treatment of Hypertension should not be applied individually to any.Hydrochioro is thiazide diuretic, suitable for light, moderate hypertension, small dose
Amount treatment hypertension (<25mg/d) adverse reaction is few, and can water-sodium retention caused by antagonism clonidine hydrochloride, but dosage is excessive can
Blood glucose, blood fat, blood uric acid rise and blood potassium can be caused to reduce.Rutin heat-clearing, cool blood, hemostasis, capillary permeability can be reduced
And increase its tension force, there are decompression and triglyceride lowering effect.This five kinds of drug ingedient low dose compatibilities can play diuresis, suppress
Sympathetic activity, expansion blood vessel, improve myocardial blood supply, sedation, antihypertensive effect is cooperateed with mutually, and side reaction is cancelled out each other.
Zhenju Jiangya Tablet has the collaboration of Chinese and Western medicine advantage, is formulated the advantages of reasonable, therefore can reach preferable antihypertensive effect.
At present, there is many problems in the preparation of Zhenju Jiangya Tablet：1. the easy moisture absorption of chrysanthemum indicum cream powder, is not easy to pelletize, is
The viscosity of particle is reduced, the general alcohol granulation for using higher concentration, not only increases cost, is also unfavorable for labour protection；②
It is easy to moisture absorption in preparation storing process, causes disintegration of tablet slack-off；3. nacreous layer powder poor compressibility, it is also easy to produce loose pieces phenomenon.
CN101829175B discloses a kind of quickly disintegrated Zhenju Jiangya Tablet agent and preparation method thereof, with CMS
Sodium, PVPP, lauryl sodium sulfate three combination are used as disintegrant, for solving preparation homogeneity shakiness
Fixed, disintegration absorbs the problem of slow.The technology fails fundamentally to solve traditional Chinese medicine ingredients viscosity and is not easy to pelletize greatly, and tablet can press
Property is poor, and being easy to moisture absorption in storing process causes to be disintegrated the problems such as slack-off, while lauryl sodium sulfate is used in prescription, increases
The excitant of intestines and stomach.
CN102973627A is related to a kind of preparation method of Zhenju Jiangya Tablet, and the invention dissolves clonidine hydrochloride with ethanol
Be well mixed afterwards with Hydrochioro, nacreous layer powder, through drying, crush after be well mixed again with chrysanthemum indicum cream powder, rutin, be made
Grain and tabletting.The invention is used and pelletized twice, complex process, and fails solve tablet poor compressibility, is easy to inhale in storing process
It is wet to cause to be disintegrated the problem of slack-off.
The content of the invention
In view of the deficiencies in the prior art, it is an object of the invention to provide a kind of compressibility is good, disintegration is rapid, dissolution rate is high
And the simple Zhenju Jiangya Tablet of preparation technology.
In order to realize the purpose of the present invention, inventor is finally obtained as follows by lot of experiments research and persistent exploration
Technical scheme：
