Anti-parasitic ivermectin transdermal solution used for livestock and preparation method thereof

Abstract

The invention relates to an anti-parasitic ivermectin transdermal solution used for livestock and a preparation method thereof. The anti-parasitic ivermectin transdermal solution comprises the following components respectively according to parts by volume: 5 to 15 parts of ethyl acetate, 20 to 30 parts of dimethyl sulfoxide, 2 to 6 parts of azone, 1 to 3 parts of isopropanol and 50 to 70 parts ofpropanediol; and the content of ivermectin is 0.3g to 1g in a solution of 100ml, and the finished product is prepared by the processes of dissolving, mixing, filtering and filling. The azone related in the prescription of the invention is a novel skin penetration enhancer, can increase the transdermal absorption of the skin to various medicines of different types, effectively avoids the pass effect of hepar, avoids peak and valley phenomena in the absorption process of the medicine, reduces the toxic or side effect caused by the correlative dosage in the medicine, prolongs the effective effecttime, changes the administration area, effectively regulates the administration dosage and reduces differences among individuals.

Description

technical field

[0001] The invention belongs to the technical field of medicine preparation, in particular to an anti-parasitic ivermectin transdermal solution for livestock and a preparation method thereof. Background technique
