摘要 |
A slow-release sodium valproate tablet with a coating layer, obtained by coating a core containing sodium valproate with a coating agent comprising ethyl cellulose having silicic acid anhydride dispersed therein. The slow-release tablets, while having a relatively small size, maintain a stable dissolution rate without being influenced by pH conditions to stably maintain the blood concentration of active agent over an extended period of time.
