Problems solved by technology

Oryzanol is insoluble in water and easily oxidized, which makes it difficult to make oryzanol into a stable preparation
The isolated cycloartenol ferulic acid ester has poorer solubility and stability under conventional preparation methods
Very low solubility and easy oxidation not only lead to low absorption rate, but also difficult to control the quality in production
Some technical schemes for solving the solubility problem of oryzanol are provided in the prior art, such as CN123428, CN2007100156403, CN2004100945568 etc. disclose technical schemes for improving the solubility of oryzanol, but these schemes have their own defects on the one hand, such as when oil-soluble preparations are used clinically Patients have a strong sense of pain, which can easily lead to muscle agglomeration and slow onset of action; the cost of liposomes is high, and the quality of the production process is not easy to control, etc.
On the other hand these schemes also do not relate to how to solve the solubility problem of cycloartenol ferulic acid ester

Abstract

The invention discloses a pharmaceutical composition of cycloartenyl ferulate oryzanolum, which comprises cycloartenyl ferulate oryzanolum, phospholipid, bile acid and / or salt of bile acid. The pharmaceutical composition effectively improves the water solubility and the stability of the cycloartenyl ferulate oryzanolum and has better grain diameter and stability than the prior product, and further, the invention provides three product forms including injectio, freeze-dried powder and kits of the pharmaceutical composition, and preparation methods thereof.

Description

technical field [0001] The invention relates to a composition. Specifically, the invention discloses a cycloartenol ferulic acid ester composition for injection and a preparation method thereof, belonging to the 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 hair 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, resisting the absorption of cholesterol, lowering serum cholesterol, preventing lipid oxidation and preventing cardiovascular diseases. In addition, oryzanol can alleviate various physical disorders and autonomic nervous disorders in women af...
