The main drugs for treating cerebral insufficiency of blood supply are as follows: 1. Anti-platelet aggregation agents: can reduce the occurrence of microemboli and reduce cerebral ischemic attacks. Commonly used is aspirin 100mg, taken orally after dinner; or tegretol 90mg, taken orally after dinner or combined with bimatoprost. Attention should be paid to monitoring the clinical treatment effect and adverse reactions during use. 2. Anticoagulants: Anticoagulation should be administered to patients with cardiogenic embolism caused by atrial fibrillation. Warfarin 6mg can be chosen to be taken orally once a night and changed to 3mg maintenance after 5 days to maintain the international standardized ratio of prothrombin at 2.0-3.0. During the use of anticoagulant drugs, attention should be paid to contraindications. 3, vasodilators and volume expansion drugs: early use of vasodilators can make microemboli move distally, thus reducing the scope of ischemia, and also can promote the establishment of collateral circulation, commonly used drugs include vincristine, etc. The commonly used vasodilator drugs are low-fraction most dextrose, which can expand blood volume, dilute blood, reduce blood viscosity, inhibit the release of coagulation factor III and produce anticoagulant effect. 4, brain tissue protective agents: calcium ion antagonists can be used to protect brain tissue, commonly used nimodipine, flunarizine, etc. There are many clinical drugs for the treatment of cerebral insufficiency, which should be used after the neurologist’s interview.
