Abstract

An ocular Jiatishaxing gel contains Jiatishaxing, carbomer and triethanol amine. Its preparing process is also disclosed.

Description

Gatifloxacin eye gel and preparation method thereof
Technical field
The present invention relates to a kind of external used medicine for the treatment of ocular infection and preparation method thereof, particularly a kind of spacetabs type eye gel for the treatment of ocular infection and preparation method thereof.
Background technology
So far, the antibiotic medicine of treatment ocular infection disease, kind is few, the aging of product.The antibiotic medicine of present clinical first-selection is ciprofloxacin, tobramycin and dexamethasone compound preparation (trade name: Tobrex).The shortcoming of Tobrex is the price comparison costliness, and by contrast, the price of disposable levofloxacin hydrochloride eye drops is then cheaper.But disposable levofloxacin hydrochloride eye drops is bigger to the eye zest, and the patient is difficult for accepting.Particularly the old antibiotic eye drop of prolonged application causes antibiotic fastbacteria increasing, so this type of antibiotic therapeutical effect weakens; And, also needing multiple dosing on the one during use, the patient is difficult for accepting.
The English name of Gatifloxacin is Gatifloxacin, is abbreviated as GFLX, and the commodity of external listing Tequin by name belongs to novel fluoroquinolone antibacterial agent thing of the 4th generation.From the characteristics of structure and antimicrobial spectrum, have good pharmacokinetics and pharmacodynamic profile, phototoxicity obviously reduces, and is difficult for producing drug resistance, and antimicrobial spectrum is wider.It at first went on the market in the U.S. in December in 1999 on the 27th, was subjected to the welcome of extensive patients deeply.Its characteristics can reduce: 1. has a broad antifungal spectrum.Except that gram negative bacteria being had the strong antibiotic activity, also have than the more powerful resisting gram-positive bacteria of other quinolones and the activity of pathogen such as anaerobe resistant, gonococcus, mycoplasma, chlamydia and mycobacterium.2. antibacterial activity is higher than ciprofloxacin and levofloxacin.3. safety is good.The clinical practice person of having no side effect accounts for 96.5%.Though the report that utilizes GFLX intravenous injection and oral administration treatment eye inflammation is arranged abroad, and effect is better.But this therapeutic modality is very inconvenient to the patient.
Gel for eye is to be adjuvant with natural, semi-synthetic or complete synthesis gel, the pharmaceutical preparation of making.Adjuvant can be selected materials such as polyacrylamide, carbopol 910, carbopol 940 for use.It is big and be easy to and features such as tear mixes that it has viscosity, and prolong drug improves bioavailability in the holdup time on eye surface.The external gel for eye use that medicines such as N-ethyl-N-(.gamma.-picolyl)tropamide, pilocarpine, chloromycetin and betamethasone are arranged of development and Application, but still do not have the report that the GFLX eye-gel preparation is studied at present.
Summary of the invention
The purpose of this invention is to provide a kind of with the Gatifloxacin be main component, have efficient sterilizing, long action time, a spacetabs type gel eye drop that adverse effect is low.
GFLX eye gel of the present invention contains the medicine of following percentage by weight:
Gatifloxacin 0.05%~0.4%
Carbomer 0.5%~1.5%
Triethanolamine 1%~2%
The preferred technical solution of the present invention is the medicine that also comprises following percentage by weight on the basis of such scheme:
Propylene glycol 8%~12%
Glycerol 8%~12%
Distilled water or purified water or water for injection add to 100%
The Gatifloxacin general by name of above-mentioned Gatifloxacin, English name are Gatifloxacin, and molecular formula is C 19H 22FN 3O 41.5H 2O, chemistry 1-cyclopropyl-6 fluoro-7-(3-methyl piperazine-1-yl) by name-8-methoxyl group-1,4-dihydro-4-oxygen-quinoline-3-carboxylic acid 1/2 hydrate; The English name of propylene glycol is PropyleneGlycol; The English name of glycerol is Glycerol; The English name of carbomer is Carbomer; The English name of triethanolamine is Trolamine; The English name of purified water is Purified Water; The English name of water for injection is Water for Injection.
Manufacturing method for above mentioned medicine is for comprising the following steps:
(1) according to dosage gets carbomer and be sprinkled into the glycerol surface, carbomer is mixed fully with glycerol with polishing; Add 150~250ml distilled water or purified water or water for injection and be ground to exquisiteness, add distilled water or purified water or the water for injection of 350~450ml again, make the abundant swelling of carbomer, be statically placed in the container, make mixed liquor (I);
According to dosage get in the distilled water or purified water or water for injection of triethanolamine adding 50~150ml, stirring is fully dissolved it and is made solution (II);
Mixed liquor (I) is added solution (II), continue again to grind, make gel-type vehicle (III);
(2) get an amount of purified water or water for injection or distilled water in addition, according to dosage add Gatifloxacin, stirring is fully dissolved it; According to dosage add propylene glycol again, stir and make its mix homogeneously, make mixed liquor (IV);
(3) under grinding, mixed liquor (IV) is slowly added in the gel-type vehicle (III), again distilled water or purified water or water for injection are added to full dose, continue to be ground to evenly;
(4) aforesaid liquid is carried out just filter and fine straining, carry out fill and sterilization again and promptly get eye gel of the present invention.
The invention has the beneficial effects as follows: because it is the gel rubber sustained-release dosage form, particularly its substrate carbomer has inherent peculiar cross-linked structure, and viscosity that it is good and hydrophilic gel make it have slow releasing function preferably.Therefore this dosage form has the advantage that viscosity is big and be easy to absorb, can prolong drug in the holdup time of mucomembranous surface, thereby fully improve the advantage of the bioavailability of novel fluoroquinolone antibacterial agent thing of the 4th generation of GFLX and pharmaceutics, pharmacodynamics; In clinical practice, can reduce administration time, prolong dosing interval, reduce whole body and absorb the untoward reaction that brings, help improving patient's compliance.Simultaneously, it has overcome old kind medicine to the drug resistance that the patient brings, and has solved the urgent need of clinical eye anti-infectious disease new drug.
Concrete embodiment
Below in conjunction with illustrated embodiments the present invention is described in further detail.
Embodiment one.Gatifloxacin eye gel is to be made by the medicine of following percentage by weight:
