Abstract

The invention relates to a caffeic acid composition which is characterized by comprising an A composition, a B composition, surface active agent, quick-effect disintegrant and lubricant; the A composition is caffeic acid and a medicinal accessory, and the B composition is a medicinal accessory; the weight ratio of the A composition and the B composition ranges from 1: 5.5 to 1: 1; and the caffeic acid accounts for 15 percent (W W) of the A composition at 10 DEG C. The standard of the caffeic acid composition is 0.95-0.105 weight part, wherein 0.1 weight part is the best. The caffeic acid composition and the preparation method thereof solves the problems concerning fast medicine disintegration and fast medicine effect and in particular greatly improves the bioavailability and the tablet stability of a caffeic acid tablet in the body.

Description

technical field [0001] The invention relates to a caffeic acid composition and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Bleeding disorder is a disease that threatens the patient's life. At present, commonly used hemostatic drugs in clinical practice, such as vitamin K and 6-aminocaproic acid, have slow hemostatic effects and have adverse reactions in varying degrees. Therefore, there is an urgent need to develop new hemostatic drugs with higher curative effect, faster action and lower side effects. [0003] Caffeic acid is a component of chlorogenic acid contained in various Chinese herbal medicines such as ramie, capillary, artichoke, etc., English name: Caffeic acid, chemical name: 3-(3,4-dihydroxyphenyl)-acrylic acid, molecular formula: C 9 h 8 o 4 , Molecular weight: 180.16, the chemical structural formula is shown in the figure below: [0004] [0005] Due to the low extraction ...
