Description
Technical field
The present invention relates to field of medicaments, specifically, the present invention relates to a kind of pharmaceutical composition for treating cerebral infarction.
Background technology
Cerebral infarction is also known as cerebral arterial thrombosis, refers to because brain blood supplies obstacle, limitation caused by ischemic, anoxic
The ischemic necrosis or cerebromalacia of brain tissue, including cerebral thrombosis (atherosclerotic infarct of brain), lacunar infarction and cerebral embolism.
Clinic is mainly shown as that the focal neurologicals such as hemiplegia, hemidysesthesia, aphasia, hemianopsia, incoordination are lacked.Cerebrovascular disease
It is common disease, the frequently-occurring disease in senescence phase, is to threaten one of three big diseases of human health, with the incidence of disease is high, the death rate is high, cause
The characteristics of residual rate height, high recurrence rate.Epidemiological study shows, cerebrovascular disease have become the big underlying cause of death of the elderly three it
One, wherein acute ischemic cerebrovascular disease accounts for 43%~65%, and case fatality rate is 15%~25%, and cerebral thrombosis is accounted for beyond bleeding
More than 70% something lost has different degrees of dysfunction in the 9/10 of cerebrovascular disease, survivor, and disability rate is higher, has a strong impact on patient
Quality of life.In recent years ischemic cerebrovascular disease morbidity has the trend of rejuvenation, and its clinical manifestation is not quite similar with gerontal patient,
Common with initial property, solitary, lacunar infarction, dyskinesia is more than sensory disturbance.Cerebral Infarction Patients are by treatment, depolarization
It is a small number of outer in acute stage recovery from illness, it is most of to undergo this process of convalescence.Therefore, the preventing and treating of cerebral infarction at restoration stage turns into society
The important topic that can be paid close attention to medical field.
The reason for modern medicine thinks cerebral infarction mainly has two major classes：First, more due to elderly brain atherosclerosis,
Blood vessel is caused to thicken, lumen of vessels is narrow, slow blood flow, the visible component in blood is gathered in intravascular, itself formation
Thrombus, occlusion, and there is the brain tissue ischemia necrosis of blood vessel domination, and then there are corresponding clinical symptoms, i.e. " cerebral thrombus shape
Into ".Young man, cerebral thrombosis is then more due to cerebral arteritis, such as CTD and bacterium, virus, spirochaete infection, cigarette
Mist disease (multiple progressive intracranial vessel narrow or occlusion), fibromuscular dysplasia, Drug and disease in the blood system, it is such as red
Blood cell increase disease, piastrenemia, thrombotic thrombocytopenic purpura etc. cause.Second, due to various external emboluses, with
Blood flow enters entocranial artery, makes the cerebrovascular acute occlusion, and causes corresponding clinical sign, i.e., " cerebral embolism ".Cardiogenic embolus,
The embolus produced such as atrial fibrillation；Non-cardiogenic embolus, the fat embolus such as fractured, performed the operation, air embolus, bacterium and parasite
Embolus etc..After cerebral infarction, the brain regional blood flow in the inaccessible artery cloth area can be caused to reduce or blood supply interruption, then the local group of brain
Ischemic, anoxic are knitted, causes brain tissue softening necrosis, local nerve systemic symptom and sign occurs.Such as：Extremity numbness, it is weak or
Paralysis, dispute tiltedly or aphasis, or has dysopia, incoordination or spirit, the disturbance of consciousness etc..
At present, western medical treatment cerebral infarction is with thrombolysis, reduction encephaledema, control blood pressure, reduction blood viscosity and platelet aggregation
Based on collection, the hypercoagulative state for improving blood, improvement Brain circlulation and protection brain cell, limbs, linguistic function rehabilitation are equipped with.
(1) thromboembolism treatment：Domestic to select streptokinase, urokinase, tissue-type plasminogen activator, general curative effect very well, can make to close more
Plug blood leads to again, and maximum side reaction is secondary cerebral hemorrhage；(2) brain safeguard measure：It is many from free radical scavenger (such as according to up to
La Feng, vitamin E etc.), opiate receptor retarding agent (Allylnoroxymorphone), calcium channel blocker (such as Nimodipine, Flunarizine) and emerging
Put forth energy acidic amino acid ARBs；(3) anticoagulant therapy：Inaccessible patient again after progressive Ischemic Stroke or thrombolysis, can be using early
Phase, short application use anticoagulant therapy, extend to prevent tampon, are now typically injected with LMWHs, a few patients also have Secondary cases
The side reaction of cerebral hemorrhage；(4) anti-platelet aggregation is treated：Conventional enteric coated aspirin, persantine or clopidogrel, it is possible to decrease brain
The recurrence rate of infraction, is a kind of preventive usage, but can not simultaneously be applied with thrombolysis or anticoagulant therapy, to peptic ulcer, is gone out
Blood patient should not also apply；(5) application Pimobendane, brain cell nutritional drugs：1~2 kind of Pimobendane application is can select, with
Alleviate and improve clinical sign, but acute stage has and should not applied during encephaledema, stand-by mannitol is alleviated after encephaledema, then with expanding
Blood vessel drug eluting；(6) Hemodilution Therapy：Typically multi-purpose D-40；(7) encephaledema is prevented and treated：For Early stage of cerebral infarction,
When especially infraction face is larger, the state of an illness is heavier, 20% mannitol dead point is commonly used, the bad person of cardiorenal function should use with caution；(8) suit the medicine to the illness and control
Treat and rehabilitation；Concrete condition depending on patient is instructed to carry out by the doctor in charge.
