Background technology
Coronary heart disease is the main killer of human health, and along with the acceleration of globalization process, cardiovascular and cerebrovascular disease begins to extend in developing country, becomes the cause of death of No. 1 in the world.World Health Organization (WHO) is classified as follows coronary heart disease: (1) silent myocardial ischemia type: be again silent myocardial ischemia or invisible myocardial ischemia, refer to truly have the objective evidence (electrocardio-activity, left chamber function, Myocardial Perfusion and myocardial metabolism etc. are abnormal) of myocardial ischemia, but lack chest pain or the subjective symptom relevant to myocardial ischemia.(2) angina pectoris: refer to by coronary insufficiency, cardiac muscle sharply, temporary transient ischemia and anoxia is caused take one group of clinical syndrome that ictal chest pain or chest discomfort be main manifestations.(3) myocardial infarction (extremely) type: refer to that atherosclerotic plaque or thrombosis on this basis appear in coronary artery, cause blood flow coronarius sharply reduce or interrupt, make corresponding cardiac muscle occur seriously and enduringly acute ischemia, finally cause myocardium ischemic necrosis, belong to the serious type of coronary heart disease.(4) ischemic cardiomyopathy type: refer to because long-term myocardial ischemia causes myocardium limitation or diffuse fibrosis, thereby it is impaired to produce heart contraction and (or) diastolic function, cause the clinical syndrome of the series of clinical manifestations such as cardiac dilatation or stiff, congestive heart failure, arrhythmia.(5) sudden death type: think at present, this patient's sudden cardiac arrest be on the basis of coronary atherosclerosis, there is coronary vasospasm or microcirculation thromboembolism and cause Acute myocardial ischemia, cause local electric physiologic derangement, cause due to temporary transient severe arrhythmia (particularly ventricular fibrillation).
Statins (statins) is hydroxy-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitor, this type of medicine is by synthetic rate-limiting enzyme (HMG-CoA) reductase of competitive inhibition endogenous cholesterol, hydroxyl first valeric acid metabolic pathway in blocking-up cell, make the synthetic minimizing of cell inner cholesterol, thereby feedback irritation cell film surface (being mainly hepatocyte) low density lipoprotein, LDL (low density lipoprotein, LDL) acceptor quantity and activity increase, make serum cholesterol to remove to be increased, level reduces.Statins also can suppress the synthetic Apolipoprotein B-100 of liver, thereby reduces the synthetic and secretion of being rich in triglyceride AV, lipoprotein.Statins is divided into native compound (as lovastatin, simvastatin, pravastatin, mevastatin) and complete artificial-synthetic compound's (as fluvastatin, atorvastatin, cerivastatin, Rosuvastatin, Pitavastatin) is the most classical and effective fat-reducing medicament, is widely used in the treatment of hyperlipemia.
Aliskiren (Aliskiren) is non-peptide class feritin blocade of new generation, can reduce renin activity in the first link blocking-up RAS system, reduce the generation of AngII and aldosterone, do not affect the metabolism of Kallidin I and prostaglandin, play the effect of blood pressure lowering and Cardiovarscular.From current research aliskiren, it is potent, high selectivity, orally active, long-acting antihypertensive drug of new generation.This medicine acts on renin dependent, so escalated dose administration only understands time expand and can not cause blood pressure rapid drawdown, and similar to ARB (losartan, telmisartan), the incidence rate of untoward reaction is compared without significant difference with placebo group.Aliskiren can be blocked reactive rising of feritin that thiazide diuretic, angiotensin converting enzyme inhibitor and angiotensin receptor antagonist cause, when small sample test is combined with hydrochlorothiazide, ramipril and irbesartan, plasma renin activity does not raise.
Also do not have at present the use in conjunction of bibliographical information aliskiren and statins to report there is no the Western medicine compound in bibliographical information aliskiren/his spit of fland yet.
Summary of the invention
The object of the present invention is to provide a kind of Western medicine compound and medical usage thereof for the treatment of coronary heart disease, this compound medicine all has significant curative effect to myocardial ischemia type, myocardial infarction type and angina pectoris coronary heart disease.
The object of the present invention is achieved like this:
Treat a Western medicine compound for coronary heart disease, active component is by following two kinds of ingredients:
(1) aliskiren or its officinal salt;
(2) statins;
Described statins is simvastatin or rosuvastain calcium.
The Western medicine compound of described treatment coronary heart disease, the weight ratio of aliskiren and simvastatin is 10~80: 1.
Preferably, the weight ratio of aliskiren and simvastatin is 25~50: 1.
The Western medicine compound of described treatment coronary heart disease, the weight ratio of aliskiren and rosuvastain calcium is 5~60: 1.
Preferably, the weight ratio of aliskiren and rosuvastain calcium is 10~30: 1.
Preferably, the officinal salt of aliskiren is fumarate, nitrate, sulfate, Orotate.
By animal experiment, study, inventor is surprised to find that described aliskiren/his spit of fland compound recipe has shown unforeseeable technique effect in prevention or treatment coronary heart disease rat.Therefore, second object of the present invention is to provide the described Western medicine compound purposes in the medicine of preparation prevention or treatment coronary heart disease.
Described coronary heart disease is myocardial ischemia type coronary heart disease.
Described coronary heart disease is angina pectoris coronary heart disease.
Described coronary heart disease is myocardial infarction type coronary heart disease.
Pharmaceutical composition of the present invention is when treatment coronary heart disease, and the people of each compound recipe is respectively with oral every daily dose:
Simvastatin/aliskiren compound recipe: simvastatin 4-10mg, aliskiren 75-300mg.
Rosuvastain calcium/aliskiren compound recipe: Rosuvastatin 5-20mg, aliskiren 75-300mg.
Compared with prior art, the Western medicine compound tool the present invention relates to has the following advantages and is significant progressive: known by the result of the test that can be effectively treated after myocardial infarction model rat, the administration of chronic myocardial ischemia rat model, the present invention containing simvastatin/aliskiren or the Western medicine compound of rosuvastain calcium/aliskiren can Synergistic treatment myocardial ischemia type, myocardial infarction type and angina pectoris coronary heart disease, give and increased clinically a kind of new medicine.
Specific embodiment
Form by animal experiment example is described in further detail foregoing of the present invention again below, but this should be interpreted as to the scope of the above-mentioned theme of the present invention only limits to following example, all technology realizing based on foregoing of the present invention all belong to scope of the present invention.
