Oral solution of colchicine and prescription composition of oral solution

Abstract

The invention particularly relates to an oral solution of colchicine and a prescription composition of the oral solution. The oral solution contains: colchicine, a thickener, a pH adjuster, a bacteriostatic agent, a solvent, a flavoring agent, a pigment, an essence and water. The weight percentage of each component to the total volume of the solution (w / v%) is: colchicine 0.005% to 0.02%, thickener 0.1% to 2%, pH adjuster 0.1% to 2%, bacteriostatic agent 0.02% to 0.2%, solvent 2% to 10%, flavoring agent 0.1% to 0.2%, pigment 0.005% to 0.02%, and essence 0.01% to 0.2%. The oral solution of colchicine provided by the invention solves the problem of sterilization filtration in the production process while ensuring the stability of colchicine.

Description

technical field [0001] The invention provides a colchicine oral solution and a preparation method thereof Background technique: [0002] Colchicine, an alkaloid, was originally extracted from the lily plant colchicine, hence the name, also known as colchicine. Pure colchicine is in the form of yellow needle-like crystals with a melting point of 157°C. Soluble in water, ethanol and chloroform. Bitter, poisonous. Colchicine can inhibit mitosis, destroy the spindle, and make chromosomes stagnate in metaphase. This abnormal division caused by colchicine is called colchicine mitosis. In such mitosis, although the chromosomes split longitudinally, the cell does not divide and cannot form two daughter cells, thus doubling the chromosomes. Since American scholar Blakesley (A.F.Blakeslee) etc. succeeded in doubling the chromosome number of Datura and other plants with colchicine in 1937, colchicine has been widely used in cytology, genetics research and plant breeding. .
