Definitions

  • the present invention relates to a traditional Chinese medicine composition and a preparation thereof, more particular to a traditional Chinese medicine composition for treating cardiovascular disease and a preparation thereof, especially a micro drop pill preparation. Also, the present invention relates to a method for preparing the traditional Chinese medicine and the preparation thereof Wherein, the method for preparing the micro drop pill preparation can be used to prepare the drop pills, coated drop pills and drop pill capsules with high drug-loading capacity.
  • Angina pectoris is a clinical syndrome which is characterized in chest pain and chest discomfort, caused by myocardial temporary ischemia and hypoxia.
  • Coronary heart disease (CHD) angina pectoris means the pectoris induced by myocardial ischemia and hypoxia that is caused by coronary arteriosclerosis or spasm, accounting for about 90% of the patients with angina pectoris.
  • the methods for treating angina pectoris are dominated by dilating vessels, reducing blood viscosity and inhibiting platelets aggregation as well as anticoagulation.
  • the chemicals include the nitrate, nitrite, ⁇ -receptor blocker and calcium antagonist.
  • these drugs are not suitable to use for long time.
  • most of them focus on symptomatic treatment with no more effect on disease progress.
  • symptoms occur after administrating the nitroglycerin, for example the head pain, head throbbing, speed-up heartbeat and even syncope (see New Pharmaceutics, 14 th edition, p 264).
  • Drop pill is a traditional preparation for traditional Chinese medicine. It has the following merits: reduced volatility of drug, increased drug stability, high bioavailability, quickened onset of effect, prolonged action in topical administration, shortened production cycle, dust pollution-free, and easily carried on.
  • the preparation method of traditional drop pill is to melt a medicine liquid and drop it into immiscible cooling medium to give the drop pill. Because the drop pill is formed by the factors of downwards gravity, surface tension of medicine liquid and internal stress, the unit drug loading capacity is small (usually, the drug loading capacity of API is about 25%) and the amount of matrix very large. This does not meet the requirement of international market that the maximum daily dose of PEG matrix should not exceed 700 mg. Moreover, it is difficult to prepare the traditional drop pill with diameter of less than 2.5 mm, so the patients have to take a lot of hard-to-swallow pills each time, which will not satisfy the fast-paced trend of modern life, and be prone to the problems of inaccurate dose. Thus, it is generally unacceptable by the international consumers.
  • Compound Salvia Drop Pill is a traditional Chinese medicine developed by Tasly Pharmaceutical Co., Ltd, which is proven to have the effects of activating blood by removing stasis as well as stopping pain by regulating Qi, used for treating chest distress and angina pectoris.
  • the main ingredients of CSDP include Salvia Miltiorrhiza, Panax Notoginseng and Borneol. Its pharmacological effects include increasing coronary blood flow, protecting ischemia myocardium by strengthening hypoxia tolerance, anti-platelet aggregation, preventing thrombosis and improving microcirculation etc.
  • the preparation of CSDP is known as a very mature technique in the prior art, there are still a lot of problems faced during preparation process, e.g. large amount of matrix and small drug-loading capacity.
  • the objective of present invention is to provide a traditional Chinese medicine composition for treating acute myocardial infarction and acute myocardial ischemia.
  • Said composition is composed of following materials by weight percentage: 50.0% ⁇ 99.9% of Salvia Miltiorrhiza and Panax Notoginseng extract and 0.1% ⁇ 50.0% of borneol.
  • the Salvia Miltiorrhiza and Panax Notoginseng extract comprises following ingredients by weight parts:
  • said composition may be prepared into various kinds of preparations, such as injections, tablets, capsules, drop pills and micro drop pills, preferably the micro drop pill.
  • Said micro drop pill means a smaller-sized drop pill than the traditional drop pill.
  • said micro drop pill has the particle size of 0.2 mm ⁇ 4 mm, especially 0.2 mm ⁇ 2 mm, most preferably 1 mm ⁇ 2 mm.
  • Another objective of present invention is to provide a compound Salvia micro drop pill (CSMDP).
  • CSMDP Salvia micro drop pill

  • the preparation method for preparing said micro drop pill comprises the steps as follows:
  • Material melting step heating and melting medicine and a drop pill matrix to obtain a molten medicine liquid
  • Dropping step delivering the molten medicine liquid to a dripper, and acquiring medicine drops of the molten medicine liquid by means of vibration dropping;
  • Condensation step cooling the medicine drops with cooling gas to obtain micro drop pills.
  • the present invention comprises technical solutions as follows:
  • a traditional Chinese medicine composition composed of the following materials by weight percentage: 50.0% ⁇ 99.9% of Salvia Miltiorrhiza and Panax Notoginseng extract and 0.1% ⁇ 50.0% of borneol, wherein the Salvia Miltiorrhiza and Panax Notoginseng extract comprises following ingredients by weight percentage:
