Abstract

The invention belongs to the technical field of medicines and particularly relates to a pharmaceutical composition. The pharmaceutical composition contains fasudil hydrochloride and nucleotide derivatives, wherein the content of the nucleotide derivatives in the pharmaceutical composition is 0.1-25 times of the content of the fasudil hydrochloride. The invention also discloses a preparation method and application of the pharmaceutical composition. The pharmaceutical composition has the effects of improving the activity of myosin light chain phosphatase to expand blood vessels, reducing the tensions of endothelial cells, improving microcirculation of brain tissues, protecting nerve to avoid apoptosis and promoting nerve regeneration so as to prevent and reduce cerebral vasospasm caused by various reasons and selectively expand the spasmodic blood vessels; and the pharmaceutical composition can also be used for inhibiting the damage of cerebral neurons, promoting the axon growth of neural cells and relieving the inflammatory response of involved brain cells.

Description

technical field [0001] The present invention relates to a pharmaceutical composition, its preparation method and application, in particular, to a pharmaceutical composition composed of fasudil hydrochloride and nucleotide derivatives, its preparation method and its application in improving and preventing arachnoid Cerebral vasospasm after inferior cavity hemorrhage and the cerebral ischemia symptoms caused by it are used to treat the sequelae of cerebral hemorrhage. Background technique [0002] Subarachnoid hemorrhage (SAH) is a type of hemorrhagic cerebrovascular disease, which can be divided into primary and secondary. Primary subarachnoid hemorrhage is caused by rupture and bleeding of blood vessels on the surface and base of the brain, and blood flows directly into the subarachnoid space. Also known as spontaneous SAH. Cerebral parenchymal or ventricular hemorrhage, traumatic subdural or epidural hemorrhage into the subarachnoid space are secondary SAH. The most comm...
