For Patients With Ischemic Stroke, Clinically Study the Effectiveness and Safety of Butylphthalide.
Study Details
Study Description
Brief Summary
This is a prospective, open, single-arm, the real world of clinical trials. The researchers plan to recruit 300 eligible patients. The main purpose of this study is to evaluate the effectiveness and safety of butylphthalide in the treatment of ischemic stroke, and to establish a population pharmacokinetic model of butylphthalide in elderly patients to explore its blood drug concentration. Correlation with its efficacy and adverse reactions.

Detailed Description
Ischemic stroke is one of the diseases that seriously threaten human health, with the characteristics of high incidence, high disability and high recurrence rate. Patients will not only suffer from impaired physical function, but also mental symptoms, social function and other obstacles, which seriously affect the quality of life.
Butylphthalide can improve the damage of central nervous system in patients with acute ischemic stroke, and can promote the improvement of patients with neurological deficits. Regarding the treatment of ischemic stroke with butylphthalide, there is still a lack of big data research based on real-world efficacy and safety; there is a lack of data on the pharmacokinetics of elderly patients and their correlation with adverse reactions.
Thus, it is estimated that 300 patients will be enrolled and given intravenous butylphthalide sodium chloride injection 25mg twice a day for 7-14 days, and then oral butylphthalide soft capsule 0.2g three times a day for 76-83 days. The patients will be collected for experiment before and after treatment. Laboratory data, electrocardiogram, NIHSS, mRS, combined medication and adverse events, etc., to evaluate the effectiveness and safety of butylphthalide in the treatment of ischemic stroke. In addition, a population pharmacokinetic model of butylphthalide in elderly patients was established for 50 of them.

Outcome Measures
Primary Outcome Measures
- The incidence of adverse events caused by treatment [90 days]
In a clinical trial, the probability of an unexpected and adverse medical event that occurs after a patient or clinical subject receives a trial drug, but it does not necessarily have a causal relationship with the treatment.
Secondary Outcome Measures
- NIHSS [90 days]
NIH stroke scale (NIHSS) to assess the degree of neurological deficit in stroke patients. The score ranges from 0 to 42 points, the higher the score, the more severe the nerve damage. Patients with a baseline assessment of> 16 points are likely to die, while those with a score of <6 are likely to recover well; for each additional point, the probability of a good prognosis is reduced by 17%
- mRS [90 days]
Modified Rankin scale (mRS) is an indicator of the efficacy of functional disability. The score ranges from 0 to 5 points, and the clinical score will be increased to 6 points to indicate death. The higher the score, the more disability the patient is.
- Correlation between blood drug concentration and adverse events [90 days]
Try to find the relationship between pharmacokinetic parameters and adverse events
Other Outcome Measures
- hemoglobin concentration [90days]
The normal range of hemoglobin concentration is 120-160g/L for adult males and 110-150g/L for adult females
- ECG [90days]
The electrocardiogram (ECG) mainly checks whether the patient's heart rate, PR interval, QRS interval, and QT interval are within the normal range.
- White blood cell count [90days]
White blood cell normal value parameters: adult white blood cell normal value (4.0~10.0)*109 /L
