Brief summary

This study is randomized, Sodium Ozagrel (Thromboxane A2 Synthase Inhibitor) controlled study on acute ischemic stroke. The primary endpoints were the rate of patients with modified Rankin Scale score of 0-1 at 3 months.

Interventions

Edaravone, at 30 mg, is intravenously administered by drip over 30 minutes b.i.d., in the morning and the evening.

DRUGSodium Ozagrel

Sodium Ozagrel, at 80 mg, is intravenously administered by drip over 2 hours b.i.d., in the morning and the evening.

Design outcomes

Primary

MeasureTime frameDescription
the Rate of Patients With a Modified Rankin Scale Score of 0-13 monthsThe number of patients with mRS score of 0-1 (good outcome) at 3 months after treatment initiation. The mRS has 6 items, where 0 = No symptoms at all, 1 = No significant disability despite symptoms, 2 = Slight disability, 3 = Moderate disability, 4 = Moderately severe disability, 5 = Severe disability. The higher scores reflect increased disability.

Values range from 0 (no deficit) to 42(dead). The number of patients with NIH stroke scale score of 0-1 at 3 months after treatment initiation.
Barthel Index Score3 monthsThe Barthel Index of Activities of Daily Living measures functional disability by quantifying patient performance in 10 activities of daily life. These activities can be grouped according to self-care (feeding, grooming, bathing, dressing, bowel and bladder care, and toilet use) and mobility (ambulation, transfers, and stair climbing). 5-point increments are used in scoring, with a maximal score of 100 indicating that a patient is fully independent in physical functioning, and a lowest score of 0 representing a totally dependent bed-ridden state. The number of patients with 95-100 Barthel Index was evaluated at at 3 months after treatment initiation.
Japan Stroke Scale (Motor Function) Score at 1 Month1 monthThe Japan stroke scale (motor function) is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. Values range from -0.26 (no deficit) to 31.29 (worst). The mean of Japan stroke scale (motor function) score at 1 month after treatment initiation.
