Abstract

The invention relates to a dispersible tablet containing oryzanol for treating neurological system diseases and its preparing process, wherein the tablet comprises (by weight parts): oryzanol 5-200, filling agent 20-200, crumbling agent 15-40, bonding agent 1-70, flowing adjuvant or lubricating agent 0-5.

Description

technical field [0001] The invention relates to the technical field of drugs for treating nervous system diseases, in particular to a dispersible tablet drug containing oryzanol and a preparation method thereof. Background technique [0002] Oryzanol is a mixture of ferulic acid esters mainly composed of cycloartenols, also known as ferulic acid esters, the English name is r-oryzanol, and it mainly exists in rice bran oil. Oryzanol is white or off-white crystalline powder, odorless; soluble in chloroform and acetone, slightly soluble in ethanol or n-heptane, insoluble in water. Because oryzanol acts on the human body to treat many diseases, its clinical application is extremely extensive. The clinically widely used dosage form of oryzanol is tablets, each containing 10 mg of oryzanol. The usage and dosage are 10-20 mg orally each time, 3 times a day. Another clinically available oryzanol dosage form is the oryzanol injection developed and marketed in recent years. It is a...
