Description
The present invention relates to a kind of with the anti-inflammatory eyecrops of diclofenac sodium (hereinafter referred DFNa) as effective ingredient, be combined with δ-cyclodextrin of belonging to water soluble Beta-cyclodextrin (hereinafter referred δ-CyD) and polyvinylpyrrolidone (hereinafter referred PVP) in this drop, have secular storage stability, and can relax stimulation eyes.
The aqueous drop of non-steroidal anti-inflammatory agent DFNa because the biosynthesis of prostaglandin is had powerful blocking effect, therefore is used to prevent the inflammatory symptom of postoperative and in operation process and the complication of postoperative when implementing cataract operation.When non-steroidal anti-inflammatory agent during, almost all want stimulating mucosal and eyes bar none, and show intensive ophthalmalgia effect as drop.
Present inventors stimulate owing to the caused eye of non-steroidal anti-inflammatory agent with mitigation in the past or ophthalmalgia act as purpose, a kind of antiinflammatory drop is provided, it is characterized in that, wherein contain the non-steroidal anti-inflammatory agent from ibuprofen, indomethacin, Kai Tuoluofen, naproxen and flufenamic acid, selected as principal agent, and contain the salt that the acid that allows on calcium or magnesium and the physiology forms and stimulate demulcent (special fair 1-19362) as eye.In addition, also provide a kind of like this anti-inflammatory eyecrops, wherein,, contained the Tween-81 of 5～10 times of amounts (weight) or α and beta cyclodextrin as cosolvent (special fair 2-6329) with respect to DFNa.In addition, present inventors have also developed a kind of like this drop, wherein be combined with the beta-schardinger dextrin-that is used for DFNa is carried out chemical modification, therefore it does not stimulate eyes behind eye dripping, and its storage stability is also good, now this drop has been proposed patent application (spy opens flat 6-16547).
In addition, a kind of curative is also disclosed, it is characterized in that, wherein contain DFNa as active component, and in the aqueous solution of forming by buffer agent, cosolvent and preservative agent, contain the stabilizing agent 2-amino-2-methylol-1 that active component and preservative agent is played Stabilization, ammediol or in its thing of the same clan, have the chemical compound (spy opens clear 62-242617) that is not more than 10 carbon atoms.On the other hand, about being combined with the drop of cyclodextrin, following patent literature being disclosed: contains 2-(2-fluoro-4-xenyl) propanoic acid or its salt and beta-schardinger dextrin-(hereinafter to be referred as β-CyD) or the anti-inflammatory eye solution of γ-CyD (special fair 3-30571); The anti-inflammatory eye solution (spy opens clear 60-136516) that contains 2-(2-fluoro-4-xenyl) propanoic acid or its salt, β-CyD or γ-CyD and calcium salt or magnesium salt; Or containing 3,4-dihydro-2,8-diisopropyl-3-sulfo--2H-1,4-benzoxazinyl-4-acetic acid or its salt be as principal agent, and contain the aqueous liquor (spy opens flat 5-213757) of cyclodextrin.
Yet, though the calcium salt or the magnesium salt that are generated by the acid that allows on the physiology demonstrate satisfied effect in mitigation aspect the stimulation of eyes, lacking the stability of long preservation, this is its shortcoming.Disclosed alpha-cyclodextrin stimulates for the eye that is caused by DFNa among the special fair 2-6329 does not have abirritation, stimulates abirritation though β-CyD has weak eye, and this effect is insufficient.Afterwards, present inventors find, as long as the water-soluble beta-CyD that will play the chemical modification effect is according to respect to DFNa being 7～50 times of mol ratios cooperations, just can obtain good result's (spy opens flat 6-16547) aspect eye stimulation mitigation, the storage stability two, but, when DFNa concentration surpasses 0.1%, just abundant inadequately to the abirritation of eye irritation.Showing goodish effect aspect the storage stability though open the clear 62-242617 drop shown in the example of passing the imperial examinations at the provincial level, after eye dripping, producing strong impulse the spy, therefore can not be satisfactory.
In addition, β-CyD is disclosed among clear 60-136516 and the flat 5-213757 of Te Kai and γ-CyD has the abirritation that eye stimulates for the effective ingredient in the drop opening as the spy to the improvement patent application of the fair 3-30571 of above-mentioned spy, but, all do not obtain ideal effect in either side for γ-CyD.
On the other hand, compare with the water-soluble beta-CyD of chemical modification, known γ-CyD has same degree or higher Local security's [going up still, Japanese drug technique (Pharm.Tech.Japan), 7 (2), 143,1991].In the past, because γ-CyD is difficult to mass production, so its price is very high, and being about β-CyD is 100 times, considers almost can't utilize from economic aspect.But,, therefore, it is being caused people's concern as drug additive owing to, can provide γ-CyD product at a low price recently to the exploitation of new manufacturing technology.
Present inventors, for develop a kind of γ of use-CyD, after eye dripping to eye non-stimulated, have long preservation stability and can use DFNa to carry out deep research by wide range of concentrations as the drop of principal agent, found that, by with DFNa, γ-CyD, PVP and as the benzethonium chloride of antiseptic or the benzyl chloride alkanamine is used in combination and pH value is adjusted in 7.0～8.5 the scope and just can reaches above-mentioned purpose, so far just finished the present invention.That is to say that the pH value that the present invention relates to a kind of DFNa of containing, γ-CyD, PVP and benzethonium chloride or benzyl chloride alkanamine is 7.0～8.5 anti-inflammatory eyecrops.
DFNa became strong in DFNa concentration greater than 0.05% o'clock usually to the stimulation of eye.Present inventors find, usually also be adjusted to 7.0～8.5 with γ-CyD and with pH value, can relax stimulation significantly to eyes, and can make high concentration in order to bring into play its therapeutic effect fully according to the symptom of various persons suffering from ocular disorders, and, wherein contain PVP jointly and as the benzethonium chloride or the benzyl chloride alkanamine of antiseptic by making, can make it become drop steady in a long-term,, thereby finish the present invention based on this brand-new discovery.
Because DFNa has very strong stimulation to eyes, therefore, the past is as the goods of drop, generally all the upper limit of concentration of DFNa is decided to be 0.1%.But, in drop of the present invention, use γ-CyD of 1～10% by merging, simultaneously pH value is adjusted to 7.0～8.5, can relax stimulation significantly, thereby can realize high concentration, therefore enlarge its scope of application significantly up to 0.7% to eyes.
Because the DFNa of high concentration can show ophthalmic prostaglandin inhibitory action and atropine mydriasis effect more significantly, therefore can not only be in the surgical operation (cataract of ophthalmology, glaucoma, ablatio retinae, vitreous body is extractd, stravismus etc.) demonstrate the therapeutic effect that keeps mydriasis and antiinflammatory or postoperative the time significantly, and to general ophthalmic diseases, just with the endogenous uvea inflammation headed by the Behcet, outer eye diseases associated with inflammation (conjunctivitis, keratitis, go up strong film inflammation, the pinguecula inflammation, hordeolums etc.) etc. the symptom relevant with prostaglandin has good therapeutic effect.
The preferred plan that is used to carry out an invention
γ-the CyD that uses among the present invention can relax the caused eye irritation of wide range of concentrations DFNa from low concentration to high concentration significantly.The effect of this wide region is that γ-CyD institute is inherent, and is that other water soluble Beta-cyclodextrins are unexistent.
The PVP that uses among the present invention can prevent the insoluble production of foreign matters from the γ-CyD in the prescription.For example polyvinyl alcohol, hydroxyethyl-cellulose, methylcellulose, hydroxypropyl emthylcellulose, sodium alginate, sodium carboxymethyl cellulose, Polyethylene Glycol etc. also have the effect that prevents that insoluble foreign body from producing to open the water soluble polymer that discloses except that PVP other among the flat 5-213757 the spy, but when trying out this technology, present inventors find, water soluble polymer beyond the PVP does not have this effect, and this is the inherent effect of PVP.
The PVP that uses among the present invention, the K value of its Fei Kenxieer (hereinafter referred K value) is preferably in 10～95 scope.Such PVP can be buied with trade name Kollidon 12PF, 17PF, 25,30 and 90 and be changed into industry (strain) by Tokyo and buy with trade name PVP K15, K30, K60 and K90 by BASF JAPAN (strain), and each commodity can both easily be buied.
The antiseptic that uses among the present invention, its objective is to provide the drop with long preservation stability, wherein especially preferably uses benzethonium chloride or benzyl chloride alkanamine.That is to say,, can from table 3, find out very significantly that benzethonium chloride or benzyl chloride alkanamine have the effect that prevent foreign body generation better than other antiseptic according to present inventors' experiment.
The compound method of drop of the present invention is, at first DFNa and γ-CyD is dissolved in the Purified Water, cooperates then to add PVP and benzethonium chloride or benzyl chloride alkanamine and with buffer agent and pH regulator agent pH value is adjusted to 7.0～8.5 and make.
