Abstract

The present invention relates to a fashudil hydrochloride oral preparation for curing ischemic cerebrovascular disease due to cerebrovascular spasm after subarachnoid hemorrhage. It can be made into tablet, capsule and granule preparation.

Description

Technical field: [0001] The invention relates to an oral pharmaceutical preparation, in particular to an oral pharmaceutical preparation of fasudil hydrochloride used for improving the symptoms of ischemic cerebrovascular diseases caused by cerebral vasospasm after subarachnoid hemorrhage. Background technique: [0002] Fasudil hydrochloride, English name: Fasudil, is a kind of protein kinase inhibitor namely intracellular calcium ion antagonist, it is a kind of medicine for the treatment of ischemic encephalopathy, and the existing pharmaceutical preparation for injection is on the market. Because the prior art is a preparation for injection, it is inconvenient to use, and at the same time, because fasudil hydrochloride is unstable in solution, the preparation process is complicated, which brings difficulties to large-scale preparation production. Invention content: [0003] According to the defects of the prior art, the present invention provides an oral preparation of f...
