Abstract
A flexible vitamine A acid liposome for treating dermatopathy is disclosed, which contains lecithin, bile salt, vitamine A acid and solvent. Its medicine in the form of solution, cream, or ointment contains said flexible vitamine A acid liposome, anti-oxidizing agent, and solvent. Its advantages are high stability, durable action, high curative effect, and less or no by-effect.
Description
Technical field
The invention belongs to the treating skin disease medicine, particularly utilize flexible lipidosome good transdermal performance, improve a kind of retinoic acid flexible lipidosome and the preparation thereof of retinoic acid treating skin disease effects such as acnes.
Background technology
Retinoic acid has multiple therapeutical effect.Oral to treatment psoriasis (psoriasis), serious nodositas and obstinate cyst hemorrhoid, granulocyte hypertrophy and leukemia, precancerous lesion, as the mucosa day shift of chamber or cervix uteri, and lichen planus, pityriasis rubra pilaris, folliculitis and Pyoderma gangrenosum etc. have obvious therapeutic action; The preparation external of variable concentrations has obvious effects to various acnes, the reparation of corium damage, the removal of skin crackle, exogenous skin aging.In being usually used in,, can produce big side effect, as pimple, erythema, decortication and allergy, xerosis cutis if concentration is big slightly to various remedy of acne; When concentration is low, does not then have keratinization and change.Though multiple retinoic acid preparation is arranged clinically, but because of it fails to solve preferably a transdermal difficult problem, limited in clinical extensive use, the azone that has added concentration and be 0.5%-2% in Chinese patent 97120956.1 " compositions that contains retinoic acid and clindamycin that is used for the treatment of acne " is as the epidermis penetrating agent, improved the transdermal performance, obviously improve therapeutic effect, but have the part patient to still have erythema, the side effect of desquamation produces.The molecule of retinoic acid contains more ethylenic unsaturation chain in addition, and is easily oxidized, therefore will add proper quantity of antioxidant in the carrier of preparation, could keep drug effect.
Summary of the invention
The purpose of this invention is to provide a kind of retinoic acid flexible lipidosome and preparation thereof, comprise retinoic acid flexible lipidosome and compound method and pharmaceutical formulation, it is characterized in that: described retinoic acid flexible lipidosome comprises the double solvents 20-40ml of lecithin 0.001-0.08 gram, cholate 0.001-0.1 gram, retinoic acid 0.01-0.1 gram, chloroform and the preparation of ethanol equivalent; Its compound method is a rotary evaporation in 37 ℃ of water-baths of constant temperature, remove organic molten coal, add 0.9% an amount of sodium-chloride water solution then, rotation was washed film 2 hours, obtain liposome suspension, in temperature be-the ice-water bath condition of 4-20 ℃ under with probe-type supersonic vibration appropriate time, obtain finished product behind the filtering with microporous membrane with 0.1-0.3 μ m at last.
Described retinoic acid flexible lipidosome pharmaceutical formulation and compound method, its prescription comprises by weight percentage: the Ka Baimu 940 of 0.2-0.7%, the vitamin E of 0.1-5%, with the 0.005-0.5% retinoic acid flexible lipidosome that retinoic acid calculates, an amount of triethanolamine and surplus are pure water; Its preparation process is earlier Ka Baimu 940 waters to be soaked a night in right amount, and transferring pH value with triethanolamine is 5.5-7.0, adds vitamin E, retinoic acid liposome and pure water to capacity, after stirring, crosses colloid mill and gets final product.
Described preparation also can be mixed with solution, cream and unguentum, and its formula components, proportioning also change thereupon.
Described flexible lipidosome also can be applicable to antibiotic, hormone, polypeptide, vaccine and vitamin.
The beneficial effect that the present invention reaches is: the retinoic acid flexible lipidosome of the present invention's preparation is a complex; have splendid pliability and automatic regulatory function; on the proliposome basis, added and had surfactant component such as the sodium cholate that makes the film deformation effect; therefore; the flexible lipidosome microsphere can see through the micropore barrier effectively; the aperture of passage also can be passed through less than the average diameter of microsphere even; when flexible lipidosome is applied topically to skin; and it is progressively dry; microsphere is changed gradient downstream and is passed skin; enter health, and do not damage the defencive function of organ.Therefore, macromolecular drug is had transdermal effect preferably, obviously increase the transit dose of small-molecule drug, the retinoic acid after its liposome has: A, and curative effect of medication increases, and stability increases, and oxidation resistance strengthens.Because skin is one of best biological barrier, surface horny layer only is 1/10th of a skin thickness, but undertaking 80% barrier task, the macromole of common drug is blocked by horny layer, the small-molecule substance that enters skin is eliminated fast by blood circulation, accumulation in skin is difficult to, the characteristic that has film deformation because of flexible lipidosome, transdermal is functional, in skin layer, can produce a large amount of, unified, the passage of broad accounts for 80% of skin, so the retinoic acid flexible lipidosome can increase the concentration that medicine sees through skin surface greatly, prolong the action time of retinoic acid under skin, help the performance of drug effect.B reduces the generation of side effect, retinoic acid by liposome after, directly do not contact top layer skin, thereby reduced the side effect generation.
Embodiment
The present invention is retinoic acid flexible lipidosome and preparation thereof.It has therapeutical effect to multiple disease according to retinoic acid, modal is the various types of acnes of treatment, directly contact epidermal area according to the described retinoic acid of background technology and easily produce serious adverse, with contain more ethylenic unsaturation chain in the molecule, easily oxidation, make drug failure, therefore the present invention has prepared retinoic acid flexible lipidosome and preparation thereof, comprise lecithin 0.03631 gram, cholate 0.0603 gram, retinoic acid 0.0332 gram in its retinoic acid flexible lipidosome optimum formula, the double solvents 35ml of chloroform and the preparation of ethanol equivalent; Its compound method is a rotary evaporation in 37 ℃ of water-baths of constant temperature, remove organic molten coal, add 0.9% an amount of sodium-chloride water solution then, rotation was washed film 2 hours, obtain liposome suspension, under-4-25 ℃ ice-water bath condition with probe-type supersonic vibration appropriate time, at last with behind the filtering with microporous membrane of 0.1-0.3 μ m finished product.Use above-mentioned retinoic acid flexible lipidosome to add other compositions and be mixed with retinoic acid flexible lipidosome preparation, its preferred plan comprises by weight percentage: 0.5% Ka Baimu 940,2% vitamin E, with the 0.025% retinoic acid flexible lipidosome that retinoic acid calculates, an amount of triethanolamine and surplus are pure water; Its preparation process is earlier Ka Baimu 940 waters suitably to be soaked a night, and transferring pH value with triethanolamine is 5.5-7.0, adds vitamin E, retinoic acid liposome and pure water to capacity, after stirring, crosses colloid mill and gets final product.The vitamin E of its adding increases the anti-oxidation function of retinoic acid, increases medicine stability and auxiliary treatment dual function.Preparation can be mixed with solution, cream and unguentum, and its formula components, proportioning also change thereupon.
Flexible lipidosome of the present invention can also produce multiple therapeutic effect with multiple components compatibility, promptly can be applicable to antibiotic, vitamin, hormone, polypeptide, vaccine.Use variable concentrations and reach different therapeutic purposes.
