Abstract
A pharmaceutical composition comprises 3-methyl-1-phenyl-2-pyrazoline-5-ketone and (+)-2-borneol. The pharmaceutical composition can be used in treating cerebrovascular disease and has lower toxic and side effects.
Description
technical field [0001] The invention relates to a pharmaceutical composition and its application in the preparation of medicines for treating cerebrovascular diseases. Background technique [0002] Cerebrovascular disease is a group of diseases that seriously endanger human health, and has become one of the important causes of human disability and death.
