Description
Technical field
The present invention relates to gram vertical boron sieve release membranes of a kind of had good sustained release effect and preparation method thereof, belong to biomedical material
Field.
Background technique
Gram vertical boron sieve (Crisaborole) is a kind of phosphodiesterase 4 (PDE4) inhibitor, and this inhibition causes intracellular
Cyclic adenosine monophosphate (cAMP) level increases, for treating fungal infection, in particular for treating onychomycosis and/or dermatophyte
Infection.The drug obtains U.S. Food and Drug Administration (FDA) approval listing in December, 2016, public by Anacor pharmacy
Department researches and develops and is responsible in U.S.'s list marketing, and the chemical name of trade name Crisaborole is 5- (4- cyano-benzene oxygen) -1,
3- dihydro -1- hydroxyl -2,1- benzoxaborole heterocyclic pentylene, English name are 4- ((1-hydroxy-1,3-
Dihydrobenzo [c] [1,2] oxaborol-5-yl) oxy) benzonitrile, shown in chemical structural formula such as formula (I):
The characteristics of medicament slow release is to reach reduction poisonous side effect of medicine by effective control to drug medical dosage, subtract
Few human body drug resistance, improves the stability of drug and the purpose of effective rate of utilization.Since the high molecular material of selection is different, drug
The control releasing mechanism of molecule is not also identical, therefore the research of Polymer Drug Delayed Release Materials has a very important significance.Mesh
Before, gram vertical boron sieve preparation is largely plaster, without reference to sustained release aspect, needs to pinpoint administration, and be easier to be wiped, cannot
Retain for a long time.
Summary of the invention
In view of above-mentioned deficiency, gram vertical boron sieve release membranes of had good sustained release effect provided by the invention and preparation method thereof are solved
The frequency that drug uses is excessively high and provides the longer skin residence time and reduces administration number of times.
In order to solve the above-mentioned technical problem, technical scheme is as follows:
A kind of gram vertical boron sieve release membranes of had good sustained release effect, are prepared from the following raw materials: active constituent, plasticizer, filler,
Sorbefacient, suspending agent, binder.
Preferably, each raw material proportioning is as follows: active constituent 15-25%, plasticizer 20-30%, filler 20-30%, inhales
Receive promotor 5-10%, suspending agent 5-10%, binder 6-15%.
Preferably, active constituent includes gram vertical boron sieve and/or gram vertical boron sieve analog derivative.
Preferably, plasticizer is selected from one of glycerol, propenyl, polyethylene glycol and/or glyceryl triacetate or several
Kind.
Preferably, filler is selected from one of microcrystalline cellulose, D-sorbite, converted starch and/or dextrin or several
Kind.
Preferably, sorbefacient is selected from one or more of propylene glycol, polysorbate and/or menthol.
Preferably, suspending agent is selected from one or more of carrageenan, guar gum and/or sodium carboxymethylcellulose.
Preferably, binder in polyvinylpyrrolidone, polycarbophil, chitosan and/or polyvinyl alcohol one
Kind is several.
The present invention also provides a kind of preparation methods of gram vertical boron sieve release membranes of had good sustained release effect, the specific steps are as follows:
A, first layer is sustained film preparation: by active constituent, plasticizer, filler, sorbefacient, suspending agent, binder
Sufficiently, melting is extruded into film with extruder for mixing；
B, second layer extended release film preparation: by active constituent, plasticizer, filler, sorbefacient, suspending agent, binder
Mixing sufficiently, adds suitable quantity of water to dissolve, stirs evenly, it is uniformly applied in above-mentioned release membranes, and drying machine drying is not to bright
Aobvious moisture；
C, it cuts to obtain the final product.
Preferably, in step B, dryer temperature is 60-80 DEG C.
In the present invention, film is prepared using a variety of film forming supplementary product compatibilities, complemented each other, it is indispensable, it plasticizer and fills out
Agent enhancing film forming is filled, sorbefacient enhances Medicated Permeation ability, and suspending agent guarantees the dispersibility of raw material in a liquid state,
The laminating degree of binder enhancing film and skin.
Bilayer film provided by the invention, first layer release membranes are prepared using the raw material of molten condition, second layer extended release film
Using aqueous solution of raw material brushing, when in use, second layer extended release film is labelled on skin, is slowly absorbed into disease to water composition
In stove, the fused raw material of first layer will continue to discharge drug, and due to diluting without solvent, concentration is higher, can be constant
Carry out treat, reach extraordinary slow release treatment effect.
