Butylphthalide- and edaravone-containing compound injection and preparation method thereof

The invention relates to a butylphthalide- and edaravone-containing compound injection and a preparation method thereof. The injection of every 100 ml contains 25-50 mg of active ingredient butylphthalide, 12.5-50 mg of edaravone, as well as absolute ethyl alcohol, hydroxypropyl-beta-cyclodextrin, an osmotic pressure regulator, an antioxidant and the like. With the adoption of the butylphthalide- and edaravone-containing compound injection, the administration dosage is greatly lowered, the burden of liver metabolism is reduced, and the incidence rate of liver adverse reactions is lowered. According to determination, with the adoption of the butylphthalide- and edaravone-containing compound injection, the administration dosage of the edaravone can be reduced by at least 20%, besides, the compound injection has a better curative effect, and the incidence rate of the liver adverse reactions is also remarkably lowered.
