Problems solved by technology

However, this invention still does not fundamentally solve the disadvantages of intramuscular injection caused by oil-soluble preparations, which can easily lead to patient pain, muscle agglomeration, and poor compliance.
Chinese patent application 2004100945568 discloses a technical scheme in which oryzanol raw materials are combined with cholesterol and phospholipids to prepare liposomes. The preparation of the technical scheme of the invention overcomes the problems of poor oral effect and low bioavailability of oryzanol
However, the injection obtained by this scheme is an injection emulsion, which must include an oil phase, and the particle size of the prepared emulsion is relatively difficult to control, and the stability is relatively poor. During the preparation, equipment such as a milk homogenizer is required, and the operation is relatively complicated and the cost is high.
[0004] In the existing technical scheme, the oil-soluble preparation is actually a semi-solid preparation because the vegetable oil cannot be removed, and the stability at room temperature is relatively poor
Virtually all solutions using vegetable oils for solubilization suffer from poor stability

Abstract

The invention discloses an officinal product of oryzanol and a preparation method thereof. The product is a kit which contains two unit preparations, wherein the first unit preparation is a composition of oryzanol, phospholipid, bile acid and / or salt of bile acid; and the second unit preparation is a solvent of the first unit preparation. The officinal product of oryzanol solves the problem of poor water solubility of the oryzanol and has simple use and easy storage.

Description

technical field [0001] The invention discloses an oryzanol medicinal product, which contains oryzanol, phospholipid, bile acid and / or its salt, and belongs to the technical field of medicine. Background technique [0002] Oryzanol is a natural mixture composed of cycloartenol-based ferulic acid esters and sterol-based ferulic acid esters. The appearance is white to light yellow crystalline powder, odorless, and has a specific fragrance. Oryzanol mainly exists in rice bran oil and its oil feet. In rice bran oil oryzanol, the content of cycloartenol ferulate is about 70-80%. Long-term studies have found that oryzanol has a variety of physiological functions, mainly including: lowering blood lipids, lowering serum cholesterol, preventing lipid oxidation and preventing cardiovascular diseases. In addition, oryzanol can also alleviate various physical disorders and autonomic nervous disorders in women after menopause, and improve the dysfunction of the base of the diencephalic ...
