Embodiment 1

[0031] prescription:

[0032] Based on the total amount of 100g, of which:

[0033] Melaleuca paper 30g,

[0034] L-Arginine 3g,

[0035] Bulking agent (mannitol) 60g,

[0036] Disintegrant (croscarmellose sodium) 6g,

[0037] Lubricant (magnesium stearate) 1 g.

[0038] Preparation process: Mix kelp paper, L-arginine, filler and disintegrant evenly, then add appropriate amount of water-based soft material, pass through a 24-mesh sieve to make wet granules, dry, and granulate with a 24-mesh sieve. Lubricant is added, mixed evenly, and then filled into capsules to make capsules.

Abstract

The invention relates to an oroxylin A solid preparation and a preparing method thereof, and belongs to the field of pharmaceutical preparations. The oroxylin A solid preparation is composed of the following components by the mass percentage: 10-60% of oroxylin A, 0.5-18% of L-arginine, 20-80% of a filling agent, 1-10% of a disintegrating agent, and 0-2% of a lubricant. L-arginine can greatly improve the solubility of oroxylin A; compared with other solubilizers, L-arginine has good compatibility with oroxylin A, and can ensure that the prepared solid preparation has good stability. The solidpreparation prepared by the preparation method has the advantages of good fluidity, good compressibility, good dissolution property, good drug stability, low processing cost and the like.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a kelp paper solid preparation and a preparation method thereof. Background technique [0002] According to the "World Health Statistical Annual Report" of the World Health Organization, malignant tumors are one of the diseases with the highest mortality rate in the world. For every 100,000 people in the world, the number of deaths due to malignant tumors is about 150. With the increasing morbidity and mortality of global tumor diseases, the research and development of cancer drugs has received more and more attention. The investment proportion of domestic and foreign research institutions and pharmaceutical companies in the research and development of cancer drug technology has been increasing. Statistics show that, At present, 40%-50% of the global new drug research and development investment is used in the research and development of anti-tumor drugs, which also makes ...
