Summary

The main purpose of this trial is to determine whether Chinese medicine (CM) for eliminating phlegm and clearing heat (EPACH) recipe continuously with nourishing Qi and activating blood circulation (NQABC) recipe, oral within 72 hours of symptom onset, improves the 15-day neurologicl deficits in participants with acute ischemic stroke.

Detailed description

Many years of clinical practice experience has found that Chinese medicine (CM) for EPACH recipe continuously with NQABC recipe can be beneficial to the recovery of neurological function in the early stage of ischemic stroke. However, there is lack of high-quality evidence of its efficacy for acute ischemic stroke currently. The primary hypothesis of this trial is that Chinese herbal therapeutic regimen of EPACH+NQABC combined with guideline-based standard treatment will improve the 15-day neurological deficits in patients with acute ischemic stroke (AIS). Totally 500 participants will be randomized to the integrative treatment group treated with EPACH + NQABC recipes granules in addition to guideline-based standard treatment or the control group with placebo and guideline-based standard treatment equally for 15 days. All patients will have a National Institutes of Health Stroke Scale (NIHSS) entry score of 4-25. Patients in each group will be treated according to guideline-based standard treatment, but patients who have received or intend to undergo intravenous thrombolysis or endovascular interventions (including intravascular mechanical thrombectomy, arterial thrombolysis, angioplasty) are excluded. The primary outcome will be determined at 15 days, and all the participants will be followed up for 90 days.
