Cerebral blood supply is insufficient to eat nimodipine effect time due to individual differences, the severity of the disease is different, cerebral vasospasm after subarachnoid hemorrhage generally need to oral nimodipine 40 ~ 60mg / times, 3 times / day, 3 ~ 4 weeks of continuous use of medication for a course of treatment; ischemic cerebrovascular disease need to be orally nimodipine 30 ~ 120mg / times, 3 times / day, even served for 1 month can alleviate the symptoms.
1. Cerebral vasospasm after subarachnoid hemorrhage: persistent contraction of intracranial arteries, vascular stenosis will cause insufficient cerebral blood supply, generally oral nimodipine 40~60mg/times, 3 times/day, consecutive medication for 3~4 weeks as a course of treatment.
2. Ischemic cerebrovascular disease: such as cerebral thrombosis, transient cerebral ischemia, etc. Generally, oral nimodipine 30-120mg/time, 3 times/day, for 1 month can relieve symptoms.
Insufficient cerebral blood supply is often associated with cerebral vasospasm after subarachnoid hemorrhage and ischemic cerebrovascular disease, and patients may have symptoms such as dizziness and headache, and vision rotation. Vasodilator drugs such as nimodipine and nicardipine can often be applied to improve the symptoms. Nimodipine can take effect after 10-15 minutes of oral administration, with a half-life of 1.1-1.7 hours, but the improvement time of the patient’s symptoms cannot be determined.
If patients have cerebral insufficiency of blood supply, it is recommended to go to the hospital, under the guidance of the doctor reasonable treatment.
