Description
The present invention relates to a kind of antitussive expectorant nano antitussive loquat medicine, the invention still further relates to the method for this medication preparation.
Folium Eriobotryae cough-relieving electuary is a kind of classical Chinese patent medicine, mainly contains effects such as antitussive reduces phlegm, and is used for cough, bronchitis.But traditional Folium Eriobotryae cough-relieving electuary 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 antitussive loquat medicine of increase evident in efficacy.
Another object of the present invention provides the preparation method of this nano antitussive loquat 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:
Nanometer Folium Eriobotryae 400-960 part nanometer Pericarpium Papaveris 300-700 part nanometer Radix Stemonae 90-210 part

1. the common Chinese decoction pieces is placed 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 ℃--and 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,, 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 temperature, under 0 to the 0.05MPa pressure,, get the antitussive loquat 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 antitussive loquat 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 Folium Eriobotryae cough-relieving electuary 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.
Another important feature of the present invention is: solid preparation of the present invention disintegrate rapidly, and solid dispersion is good in water, absorb fully, the bioavailability height, the pharmacological action effect that mainly contains effective constituent is significantly higher than conventional formulation.
