Abstract
The present invention relates to a composition containing acrylamide which comprises (A), acrylamide monomers; (B), acrylic ester or acrylamide monomers; (C), a photoinitiator occupying 0.1% to 15% of the mass of the composition. The proportion of the monomers A to the monomers B can be arbitrarily regulated. Polymer thin films prepared from the composition can be used as controlled release films of a transdermal drug delivery system TDDs. The reification performance of the thin films can be fine regulated by regulating the species and the content of the monomers A and the monomers B in the composition so as to quickly prepare the controlled release films of the transdermal drug delivery systems suitable for different kinds of medicine.
Description
Technical field
The present invention relates to a kind of photocurable monomer composition, be specifically related to a kind of composition that comprises acrylamide, can be used as the release-controlled film in the preparation transdermal delivery system.
Background technology
Transdermal delivery system is meant that medicine discharges from the device of particular design, by complete skin absorption, enters the controlled release drug administration formulation of systemic blood system.Transdermal delivery system can be divided into two big class, i.e. membrane controlled release type and skeleton dispersion patterns basically.The membrane controlled release type transdermal delivery system is that medicine or transdermal absorption accelerator are rolled into the storage storehouse by release-controlled film or other controlled-release materials, by the character control release rate of drugs of release-controlled film or controlled-release material.Scopolamine (trade(brand)name Transderm-Scop), clonidine (trade(brand)name Catapres TTS) are film controlling types in the at present commercially available patch, and controlling diaphragm is a microporous polypropylene membrane; Pannonit (trade(brand)name Transderm-Nitro), fentanyl (trade(brand)name Duragesic), estradiol (trade(brand)name Estraderm), testosterone (trade(brand)name Androderm) are film controlling types, and release-controlled film is a polyethylene vinyl acetate; Nicotine (trade(brand)name trade(brand)name NicoDerm CQ) is a film controlling type, and controlling diaphragm is a polyethylene film.
At European patent No.46069, U.S. Patent No. 3,797 is described in 494 and utilizes microporous membrane control rate of releasing drug.The hole of film from 0.1 to 0.85, the curvature of film from 1 to 10, from 10 to 100 microns of film thicknesses, the film of usefulness has polypropylene, tetrafluoroethylene, polycarbonate, polyvinyl chloride, cellulose acetate, nitrocellulose, polyacrylonitrile etc. for example.Their shortcoming is that the kind of the microporous membrane that can Gong select for use is few, does not satisfy the formulation that more medicine is made percutaneous dosing.
In U.S. Patent No. 6,537, the Scopolamine Patch that is described among the 571B1, U.S. Patent No. 4,681, the Deponit TTS that is described in 584, used release-controlled film all is the multipolymer of ethene-vinyl acetate.Shortcoming is an organic solvent residue problem in the ethylene-vinyl acetate copolymer, and needs constantly to regulate the content of vinyl acetate between to for plastic to regulate the permeability of medicine.
At European patent No.1103260A2, in the clonidine patch that is described among the U.S. Patent No. 2004/0028726A1, utilize vinylformic acid-(2-ethyl) own ester, methyl methacrylate, vinylformic acid and vinyl acetate, Raolical polymerizable takes place, and the multipolymer that obtains can be controlled the release of medicine simultaneously as pressure-sensitive adhesive layer and bin-storing layer in the patch.Shortcoming is that Raolical polymerizable is influenced by several factors, factors such as the time that responds, temperature of reaction, raw material initial concentration, solvent, and also there is the residue problem of organic solvent in patch.
The film of in transdermal delivery system, using, generally speaking the release-controlled film kind lacks, and alternative little, this brings very big obstruction for the exploitation of percutaneous drug administration preparation.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of excellent curing performance that has is provided, can produce the monomer composition of the polymkeric substance that can be used for the release-controlled film in the transdermal delivery system.
For the shortcoming that the kind that solves release-controlled film in the existing transdermal delivery system lacks, the present invention finds that on extensive and deep research basis it is abundant to adopt a kind of special photo curable monomer composition just can obtain kind, the release-controlled film of excellent performance.Said composition comprises: (A) a kind of acrylamide monomer; (B) a kind of acrylate or acrylamide monomer; (C) a kind of light trigger accounts for 0.1%~15% of composition quality; The ratio of monomer A, B can be regulated arbitrarily in the composition.
