脑血管病的病因,主要是血液动力学的异常、血液流变学的异常和血管壁病变三种。因此,某种药物如能引起上述病因中的任何一种,就可能引起脑血管病发作。药源性脑血管病按其发病机理可分以下五类。一、药源性高血压药源性高血压已屡见报告。不容置疑,高血压是脑出血的重要原因。若病人原已患有高血压病、动脉硬化、动脉瘤或血液凝固异常,则药源性高血压更易导致脑出血。 1.肾上腺素能药:肾上腺素能药具有兴奋α和β-受体作用,且常以一种占优势。这些药物的升压作用 The etiology of cerebrovascular disease, mainly hemodynamic abnormalities, abnormalities in blood rheology and vascular wall lesions in three. Therefore, any drug that causes any one of these causes may trigger a stroke. Drug-induced cerebrovascular disease according to its pathogenesis can be divided into the following five categories. First, drug-induced hypertension Hypertension has been reported. Undoubtedly, hypertension is an important cause of cerebral hemorrhage. If the patient had been suffering from hypertension, arteriosclerosis, aneurysm or abnormal blood coagulation, drug-induced hypertension is more likely to lead to cerebral hemorrhage. 1. Adrenergic Drugs: Adrenergic drugs are excited α and β-receptor effects, and often a predominance. The boost of these drugs
