Abstract

The invention discloses a stable medicinal combination which contains active ingredient riluzole and pharmaceutical auxiliary material. The medicine combination is mainly used for the clinical treatment of amyotrophic lateral sclerosis.

Description

technical field [0001] The invention designs a pharmaceutical composition, especially a pharmaceutical composition containing riluzole. Background technique [0002] Riluzole (2-amino-6-trifluoromethoxy-benzothiazole) is a benzothiazole compound with clear pharmacological activity, which is mainly produced by inhibiting the activation of sodium channels and reducing the release of glutamate Neuroprotective, anticonvulsant, antidepressant, sedative and anti-physical dependence and other pharmacological effects. [0003] Amyotrophic lateral sclerosis is a motor neuron disease characterized by muscle weakness, muscle contractures, fasciculations, and atrophy that affects the muscles of the throat and throat, making speech and swallowing difficult; Involvement of the respiratory muscles, resulting in dyspnea and death. Although the pathogenesis of ALS has not been fully elucidated, it has been theorized that glutamate is responsible for cell death in this disease. Riluzole ex...
