Study summary

This is a retrospective, multi-center, real-world study. The researchers plan to include 10,000 cases of ischemic stroke patients using butylphthalide and 10,000 cases of ischemic stroke patients using Edaravone. The main purpose is to analyze the effectiveness and safety of butylphthalide and establish the drug risk assessment management plan.

Read the detailed description

Ischemic stroke is a type of syndrome in which blood supply to the brain is impaired due to various reasons, leading to local brain tissue ischemia, hypoxic necrosis, and corresponding neurological deficits. It has a high incidence, high morbidity and disability. Features of high recurrence rate.

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 butylphthalide in the treatment of ischemic stroke, there is still a lack of big data research based on the efficacy and safety of the real world.

Therefore, it is planned to include 10,000 patients who used butylphthalide or Edaravone in five hospitals from 2019 to 2021, and record the basic information of the patients, medication status and related test results. The data was cleaned, sorted and analyzed to evaluate the effectiveness and safety of butylphthalide in the treatment of ischemic stroke.

What researchers measure

Primary outcomes

  1. The incidence of adverse events

    The probability of unanticipated and adverse medical events after the patient receives medication, but it does not necessarily have a causal relationship with the treatment

    Time frame: 90days

Secondary outcomes

  1. 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: 90days

  2. 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: 90days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 9, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
