The objective of the invention is to provide a medicinal composition having the advantages of high biological availability, quick-speed medicine release, quick-speed effect, higher medicinal content, easy administration, and low price. The drop pill is prepared from rhubarb horsetails as raw material, and medicinal carrying agent as the base material.
Description
Technical field
The present invention relates to a kind of clearing away heat and loosing the bowels effect that has, be used for damp and hot dyspepsia, the pharmaceutical composition of treatment for diseases such as constipation and damp-heat type inappetence particularly is a kind of drug composition oral preparation that feedstock production forms with the Chinese herb rhubarb.
Background technology
The Radix Et Rhizoma Rhei constipation relieving powder that is prepared from according to given preparation method among the national drug standards WS-11058 (ZD-1058)-2002, it is a kind of clearing away heat and loosing the bowels effect that has, be used for damp and hot dyspepsia, the oral tablet of treatment for diseases such as constipation and damp-heat type inappetence, through clinical verification, determined curative effect is the common drug that clinical and family is used for the treatment of above-mentioned disease.
Below be prescription and technology and the brief description that WS-11058 in the drug standard (ZD-1058)-2002 provides:
Prescription: Radix Et Rhizoma Rhei 400g, sucrose 980g
Method for making: get the Radix Et Rhizoma Rhei fritter, add 75% alcohol reflux 2 times, each 1 hour, merge extractive liquid, filtered, and it is 1.30 clear paste that filtrate is concentrated into relative density, adds sucrose, and mixing is made granule, drying, promptly.
Function cures mainly: clearing away heat and loosing the bowels; Be used for the excess-heat dyspepsia, constipation and damp-heat type inappetence.
Owing to reasons such as technologies of preparing, the oral formulations of most drug, especially the oral formulations of Chinese medicine, exist all after taking that dissolve scattered time limit is long, dissolution is low, absorption is relatively poor, problem such as liver sausage first pass effect and bioavailability are lower, thereby influence the performance of drug effect, also directly affect therapeutic effect.In addition, conventional peroral dosage form is as tablet, capsule, granule (electuary) etc., in preparation process because the technology of granulation is arranged, therefore can produce bigger dust pollution, can staff's health be worked the mischief to a certain extent, also can cause certain pollution simultaneously to environment.Moreover, the complex manufacturing of conventional oral formulations, production cost is higher, thereby patient's drug cost is also improved thereupon, is unfavorable for improving the ability of seeking medical advice of extensive patients, also is unfavorable for improving the general health level of society.
Summary of the invention
Purpose of the present invention, be to replenish the existing damp and hot dyspepsia that is used for, the deficiency of the oral drug preparation of treatment for diseases such as constipation and damp-heat type inappetence, a kind of bioavailability height is provided, and has quick release, fast produce effects, the medicament contg height, taking convenience, cheap, and free of contamination aborning oral formulations constipation relieving dripping pills with rhubarb.Constipation relieving dripping pills with rhubarb involved in the present invention is a raw material with the Chinese herb rhubarb, is prepared from the pharmaceutically suitable carrier as substrate.
Be prepared by the following technical solutions, can obtain constipation relieving dripping pills with rhubarb involved in the present invention:
[preparation method]
1. the preparation of drug extract: with g or kg is unit, and it is an amount of to get Radix Et Rhizoma Rhei, adds 75% alcohol reflux 2 times, each 1 hour, merge extractive liquid, filters, and it is 1.30～1.35 thick paste that filtrate is concentrated into relative density, or continue to make drying, be ground into dry powder, promptly;
2. substrate: the mixture of one or more in pharmaceutically suitable carrier such as polyethylene glycols, sorbitol anhydride class, polyoxyethylene sorbitol acid anhydride class, polyoxyethylene stearate 40 esters, betacyclodextrin, poloxamer, carboxymethyl starch sodium, sodium lauryl sulphate, stearic acid, sodium stearate, glycerin gelatine, Lac;
