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.
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.
8,255 studies on the registry are indexed under Stroke; 2,056 are open to participants now.
This study's planned enrollment of 300 is above the median of 49 across 6,024 interventional studies indexed under Stroke.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Drug: Butylphthalide
Butylphthalide sodium chloride injection 25mg, 2 times a day, 7-14 days, followed by 0.2g butylphthalide soft capsules, 3 times a day, 76-83 days, a total of 90 days.
Also known as: 3-n-Butylphthalide
The incidence of adverse events caused by treatment
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.
Time frame: 90 days
NIHSS
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%
Time frame: 90 days
mRS
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.
Time frame: 90 days
Correlation between blood drug concentration and adverse events
Try to find the relationship between pharmacokinetic parameters and adverse events
Time frame: 90 days
hemoglobin concentration
The normal range of hemoglobin concentration is 120-160g/L for adult males and 110-150g/L for adult females
Time frame: 90days
ECG
The electrocardiogram (ECG) mainly checks whether the patient's heart rate, PR interval, QRS interval, and QT interval are within the normal range.
Time frame: 90days
White blood cell count
White blood cell normal value parameters: adult white blood cell normal value (4.0\~10.0)\*109 /L
Time frame: 90days
