In this clinical study, the efficacy and safety of ALbumin is to be evaluated for the patients occurred within 12 hours of acute ischemic stroke.

According to the statistics of the cause of death in 2008 by the Statistics Korea, the stroke was accounted for a large proportion of cause of death among adults, as well as higher mortality, severe sequelae. These stroke in acute phase showed neurological deterioration over 50% of the patients after beginning of treatment and the sequelae resulting in that the nervous tissue was not regenerated is regarded as irreversible changes.

The test group administered 20% albumin based on 1.25g/kg (up to 100g (500ml) over 80kg body weight) to the patients occurred within 12 hours of the onset of symptoms and equal amount of placebo (saline solution (0.9% normal saline)) administered to the control group will be compared to evaluate the efficacy and safety of ALbumin for the patients with acute ischemic stroke.

Inclusion Criteria:
