Butylphthalide is relatively more used in clinical practice, mainly for ischemic diseases, and for diseases of hemorrhagic nature can only be applied at a later stage when they are relatively stable. Butylphthalide can block multiple pathological links caused by ischemic stroke, has a strong anti-ischemic effect, can significantly reduce the local brain tissue ischemic area, reduce the surrounding brain edema, improve brain energy metabolism, promote energy recovery, reduce the microcirculation and blood flow energy in the ischemic area, accelerate the absorption of nutrients, inhibit the apoptosis of various neuronal cells that are not completely necrotic, and partly also has anti-thrombotic and anti-platelet aggregation effects. The effect of anti-thrombosis and anti-platelet aggregation, so this drug is still quite good. However, it is important to note that this drug is toxic and should be continued under the premise of normal liver and kidney function.
