intravenous tranexamic acid (TXA) infusion: Intravenous tranexamic acid will be administered as an initial dose of 1 g (10mL: 1g, diluted in 90 mL normal saline) over 10 minutes, followed by a maintenance dose of 1 g over 8 hours (10mL: 1g, diluted in 240 mL normal saline). Intensive blood pressure lowering will be maintained throughout the treatment period until 24 hours after onset.
Placebo: An intravenous placebo (10mL NS, diluted in 90mL NS) matching the specification and appearance of TXA will be administered as an initial bolus over 10 minutes, followed by a continuous infusion of placebo (10mL NS, diluted in 240mL NS) over 8 hours, with intensive blood pressure lowering maintained throughout the treatment period and continued until 24 hours after symptoms onset.
Study summary
This is a prospective, multicenter, randomized, quadruple-blind, placebo-controlled study. This study aims to estimate the safety and efficacy of intravenous tranexamic acid (TXA) combined with intensive blood pressure lowering in ultra-early spontaneous intracerebral hemorrhage (ICH).
