Abstract

The invention discloses an aqua-colchin percutaneous absorption plaster agent to treat acute gout and preparing method in medicinal preparation domain, which is characterized by the following: allocating 0. 5-1. 5 wt aqua-colchin, 3-8 wt transdermal accelerant and 1000-1500 wt pressure-sensitive adhesive; hypercritical-extracting bulb of edible tulip with carbon dioxide; getting the aqua-colchin; dispersing and refining the aqua-colchin to nanometer grade; controlling the nanometer grade grain size below 500nm. This invention can increase biological availability above 10 double, which can modify treating effect distinctively.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations characterized by sheet-like base materials, or transdermal drug delivery preparations. More specifically, it is prepared by using a carbon dioxide supercritical extraction method based on colchicine extracted from Arthia chinensis and adding a medicinal base A colchicine transdermal absorption patch for treating acute gout and a preparation method thereof. Background technique [0002] Transdermal drug delivery system or percutaneous absorption patch refers to a type of preparation that is applied through the skin, and the drug is absorbed through the skin into the blood circulation of the whole body and reaches an effective blood concentration to achieve disease treatment or prevention. The characteristic of the transdermal absorption patch is that the transdermal drug delivery system can avoid the first-pass effect of the liver and the inactivation of the drug in the gastroin...
