It is prepared through microwave extraction, decompressing concentration, spray drying in supersonic jet and other steps. It has high biological utilization and obvious treating effect.
Description
The present invention relates to the nano nephritis treating medicine of a kind of heat-clearing and toxic substances removing, inducing diuresis to remove edema, the invention still further relates to the method for this medication preparation.
Kidney inflammation tablets is a kind of classical Chinese patent medicine, mainly contains effects such as heat-clearing and toxic substances removing, inducing diuresis to remove edema, is used for acute and chronic nephritis, urinary tract infection.But traditional kidney inflammation tablets disintegrate is slower, absorbs not exclusively, and bioavailability is not high, slow curative effect.
The object of the present invention is to provide a kind of bioavailability height, solid dispersion is good, absorbs fully the nano nephritis treating medicine of increase evident in efficacy.
Another object of the present invention provides the preparation method of this nano nephritis treating medicine.
To achieve these goals, the present invention takes following technical scheme:
Medicine of the present invention is to make (consumption is a weight portion) by following component:

2. above-mentioned extract is carried out concentrating under reduced pressure, temperature is 30 ℃--60 ℃, the time is 3-72 hour, collects volatile material in the Chinese medicine simultaneously in addition;
3. decompressed concentrate and volatile material merging are placed spray drying tower, use the supersonic jet technology, 330 meters of effluxvelocities--990 meter per seconds, at 30 ℃--60 ℃ of temperature, under 0 to the 0.05MPa pressure,, promptly make the nanometer prepared slices of Chinese crude drugs with the instantaneous drying of hypersonic velocity.
3. the nanometer prepared slices of Chinese crude drugs (powder) are prepared mixing in described ratio, according to Chinese Pharmacopoeia version two-shift system in 2000 agent standard, make pill, powder, tablet, suppository, granule, membrane, capsule, microcapsule, drop pill, aerosol, injection, unguentum, medicated wine, syrup, oral solution.
Two of medicine method for making of the present invention is:
1. be equipped with whole common Chinese decoction pieces in the proportioning ratio, place extraction pot, solubilizer also imports microwave extracting, makes its speed with 20--30 hundred million times/second do the change in polarity motion, and the temperature of its microwave extracting is 30 ℃-60 ℃, time 1-10 hour;
2. above-mentioned extract is carried out concentrating under reduced pressure, temperature is 30 ℃--60 ℃, the time is 3-72 hour, collects volatile material in the Chinese medicine simultaneously in addition;
3. decompressed concentrate and volatile material merging are placed spray drying tower, use the supersonic jet technology, 330 meters of effluxvelocities--990 meter per seconds, at 30 ℃--60 ℃ of temperature, under 0 to the 0.05MPa pressure,, get nephritis preparation nano powder with the instantaneous drying of hypersonic velocity jet;
4. its nano powder is made aforementioned various preparation according to Chinese Pharmacopoeia version standard preparation in 2000.
The pharmacological effect that above-mentioned two kinds of methods are made nano nephritis treating medicine is identical.
A kind of important feature of the present invention is: the made drug material of the present invention has reached nanoscale, common kidney inflammation tablets preparation material is micron or the above particle diameter of millimeter, can only cross the 80-120 mesh sieve, the drug material that the present invention is made, particle diameter is at 0.1--200nm, the overwhelming majority can be crossed the 1200--1500 mesh sieve less than 100nm.
