Abstract

The invention discloses a crisaborole dampness eliminating diuretic sustained-release membrane and a preparation method thereof. The membrane is prepared by the following raw materials: 9-18mg of crisaborole, 0.2-1.2mg of matrine extract, 0.2-1.2mg of garden balsam stem extract, 1-2.5mg of modified starch, 0.6-1.0mg of carbopol and 4-10mg of glycerol. The problem that the frequency of drug use istoo high is solved, longer skin retention time can be achieved, and the dosing times can be reduced. The resistant starch has good gelation property but loose structure. The addition of the carbopol and the glycerin can improve the structural strength, so that the materials are prone to form the membrane, and the yield is improved.

Description

technical field [0001] The invention relates to a slow-release film for dryness and diuresis of criborole and a preparation method thereof, belonging to the field of biomedical materials. Background technique [0002] Crisaborole, an inhibitor of phosphodiesterase 4 (PDE4), which results in increased intracellular levels of cyclic adenosine monophosphate (cAMP), is used in the treatment of fungal infections, more specifically Onychomycosis and / or fungal skin infections. The drug was approved for marketing by the U.S. Food and Drug Administration (FDA) in December 2016. It was developed by Anacor Pharmaceuticals and is responsible for marketing in the United States. The trade name is Crisaborole and its chemical name is 5-(4-cyanophenoxy )-1,3-dihydro-1-hydroxy-2,1-benzoxaborole, the English name is 4-((1-hydroxy-1,3-dihydrobenzo[c][1, 2] oxaborol-5-yl)oxy)benzonitrile, the chemical structural formula is as shown in formula (I): [0003] [0004] The characteristic of d...
