Analyzing the Pharmacodynamic Substances and the Effects of Yiqihuayu Decotion for Acute Ischemic Stroke (PHYSIS)

Phase 2
Not yet recruiting
Conditions
Ischemic Stroke, Acute
Interventions
Drug: Yiqihuayu Decotion
Registration Number
NCT05560152
Lead Sponsor
Ying Gao
Brief Summary

The main purposes of this trial are to analyze the pharmacodynamic substances and the effects of Yiqihuayu Decotion for acute ischemic stroke. The trial is a non-randomized, controlled clinical trial.

Detailed Description

Yiqihuayu Decotion is effective for acute ischemic stroke clinically, but there is lack of sufficient and reasonable explanation of its intervention effects currently. In order to further clarify the main pharmacodynamic substances of Yiqihuayu Decotion in the treatment of acute ischemic stroke, this study intends to carry out a non-randomized, controlled clinical trial. The primary hypothesis is that, compared with the control group, Yiqihuayu Decotion will produce serial changes in plasma metabolites at pre-dose and 9 days, as well as urine metabolites at pre-dose, 8 days, 9 days and 10 days. The serial changes may be the potential support to explain the intervention effect of Yiqihuayu Decotion. After enrollment, all participants will undergo a 2-day Traditional Chinese Medcine washout period to ensure that the results of pharmacodynamic substances will not be disturbed.

Primary Outcome Measures
NameTimeMethod
Differences in Caffeic acid, Amygdalin, Paeoniflorin between experimental group and control group.3 days, 8 days, 9 days, 10 days

Differences in the content of Caffeic acid, Amygdalin, Paeoniflorin in plasma and urine samples between experimental group and control group.

Secondary Outcome Measures
NameTimeMethod
The proportion of life dependency1 day, 30 days

The proportion of life dependency is defined as Modified Rankin Scale (mRS) score 0-2. The mRS score ranges from 0 (best score) to 6 (worst score).

The change of neurological deficits1 day, 3 days, 9 days

The change of neurological deficits is measured by the change of National Institute of Health Stroke Scale (NIHSS) score, ranging from 0 (best score) to 42 (worst score).
