Abstract

The invention discloses a tizanidine hydrochloride sustained-release preparation and a preparation method thereof, wherein the tizanidine hydrochloride sustained-release preparation contains tizanidine hydrochloride, a sustained-release skeleton material, a filler, a binder and a glidant according to a certain ratio. According to the present invention, the tizanidine hydrochloride sustained-release preparation can maintain the sustained release effect for 24 h, can avoid the excessive fluctuation of blood drug concentration and improve medication safety, effectiveness and compliance after taking, and further can reduce side effects; and the preparation process is simple, and the controllability of the process is strong.

Description

technical field [0001] The invention relates to a tizanidine hydrochloride sustained-release preparation and its preparation process and application, in particular to a tizanidine hydrochloride sustained-release tablet. Background technique [0002] TiazanidineHydrochloride is a central skeletal muscle relaxant with an imidazoline structure, the chemical name is 5-chloro-N-(4,5-dihydro-1H-imidazol-2-yl)-2, 1,3-benzothiadiazol-4-amine, its molecular structure is as follows: [0003] [0004] It is currently the only new type of central skeletal muscle relaxant and central α2 adrenoceptor agonist with gastrointestinal protective effects on the market. It was first developed by Novartis in Switzerland and first released in Denmark in 1988. It was launched in Switzerland and Switzerland, and subsequently obtained sales licenses in more than 20 countries including Europe, the United States, and Japan. It is clinically used for the treatment of increased skeletal muscle tensio...
