[beneficial effect]
According to drug standard WS promulgated by the ministries or commissions of the Central Government
3The mountain green tea decompression sheet that the preparation method that provides among-the B-2838-98 is prepared from, it is a kind of heat-clearing and toxic substances removing that has, the suppressing the hyperactive liver and subsiding YANG effect, be used for the treatment of vertigo and tinnitus, the headache feeling of fullness in the head, the oral tablet of susceptible to lose temper due to restlessness is through clinical verification, determined curative effect is the common drug that clinical and family is used for the treatment of above-mentioned disease.
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.
Dropping pill of folium ilicis hainanensis involved in the present invention is compared with the mountain green tea decompression sheet has following beneficial effect:
1. dropping pill of folium ilicis hainanensis involved in the present invention; utilize surfactant to be substrate; make solid dispersion with the extract that contains the Folium Ilicis hainanensis effective ingredient, make medicine be molecule, colloid or microcrystalline state and be scattered in the substrate, the total surface area of medicine increases; and substrate is hydrophilic; medicine is had wetting action, can make that medicine is rapidly molten to loose into microgranule or solution, thereby make the dissolving of medicine and absorb and accelerate; thereby improved bioavailability, brought into play efficient, quick-acting effects etc.
2. dropping pill of folium ilicis hainanensis involved in the present invention, contact promptly with saliva and to dissolve rapidly, and absorb by oral mucosa, not only rapid-action, and the influence of not taken food, promptly all can containing take after meal ante cibum, can not produce any residual harmful substance at gastric yet, thereby make that patient's medication is safer, also have medication convenience, characteristic of accurate simultaneously.
3. dropping pill of folium ilicis hainanensis involved in the present invention mixes the extract that contains active constituents of medicine mutually with molten matrix, splashes in the not miscible condensed fluid and makes.Therefore, the stability of drug height, not facile hydrolysis, oxidation, and the operation be under liquid state, to carry out, no dust pollution is not subject to the influence of crystal formation, thereby has guaranteed the quality of medicine, has increased stability.
4. production technology, the equipment of preparation drop pill are simple, easy to operate, the automaticity height, and labor intensity is low, the production efficiency height.Workshop does not have dust simultaneously, helps labor protection and environmental protection yet.
5. the production cost of preparation drop pill is usually with about 50% of other oral formulations of kind, and compares with oral liquid, and the dosage of drop pill is accurate, thereby makes the patient take metering control easily.
