Abstract
The invention relates to an ophthalmic gel containing the active ingredient of bromfenac sodium hydrate and a preparation method thereof; the bromfenac sodium hydrate ophthalmic gel contains the active ingredient of bromfenac sodium hydrate, macromolecular hydrogel substrate, osmotic pressure regulator, bacteriostat, antioxidant, metal ion chelating agent, pH regulator and water for injection; the ophthalmic gel has convenient application and quick effect; particularly, the gel possesses certain viscosity and can stay in the eyes for a long time, thus overcoming the defect that eye drops can only stay in the eyes for a short time after being diluted by tears and achieving more effective therapeutic effect.
Description
Technical field
The present invention relates to a kind of gel for eye that contains the active ingredient bromfenac sodium hydrate and preparation method thereof, belong to medical technical field.
Background technology
Bromfenac sodium is a kind of non-steroidal antiinflammatory drugs; it is the derivant of 2-amino-3-benzoylphenylacetic acids (amfenac); mainly be by suppressing the synthetic of cyclooxygenase blocking-up prostaglandins inflammation modulators; thereby generation antiinflammatory action; prostaglandin is except that having general action, or the important regulator of eye inflammation.
The bromfenac sodium chemical name is 2-amino-3-(4-benzoyl bromide)-sodium phenylacetate sesquialter water platform thing, and its chemical constitution is as follows:
Bromfenac sodium is easily molten in water, and is almost insoluble in 0.1M hydrochloric acid solution, acetonitrile and the acetone, dissolves slightly soluble in ethanol in methanol.
Bromfenac sodium is mainly used in the inflammation treatment (blepharitis, conjunctivitis, strong film inflammation (comprising strong film inflammation) and post-operation inflammatory) of outer eye and preceding eye at present.
Summary of the invention
The object of the invention provides the gel for eye that a kind of active ingredient is a bromfenac sodium hydrate, soluble in water according to bromfenac sodium, aqueous solution is alkaline physicochemical property, and bromfenac sodium sodium salt in acid solution dissociates, become bromfenac, and further be decomposed into the bromfenac sodium precursor, and lose its drug action, influenced its stability and drug action to a great extent.Therefore the bromfenac sodium gel for eye use is that bromfenac sodium is mixed in the aqueous gel substrate, by regulating pH value stability with the assurance active ingredient in alkaline range, regulate the ophthalmic preparation that the osmotic pressure scope makes by osmotic pressure regulator, so that ocular absorption and reduction ophthalmic administration to the eye mucous membrane irritation, also further increase the stability of gel by antibacterial, antioxidant and complexing of metal ion agent; And bromfenac sodium hydrate is prepared into gel for eye to have easy to use, particularly gel has certain viscosity retention time is longer within the eye, improved eye drop to be diluted and caused the low and short shortcoming of the time of staying within the eye of drug level, played the therapeutical effect of continuous and effective by tear.
Another object of the present invention provides the preparation method that a kind of active ingredient is the gel for eye of bromfenac sodium hydrate.
The zest of the size of gel for eye pH patient's eye to medicine stability with when using all can have certain influence, therefore in the present invention's research by a large amount of experiments to pH regulator agent select, make its pH value remain on 7-10, both guaranteed the stability of active ingredient bromfenac sodium hydrate, alleviated the zest of preparation again eye.Carried out the research of eye irritation test with 6 prepared samples of embodiment of the present invention in 14 days with every group of 3 single-doses of regular grade large ear rabbit and successive administration, bromine phenolic acid sodium gel for eye use single and continuous 14 days eye drips contrast to dripping same dosage 0.9% sodium chloride injection.The single-dose group after twice administration 1,2,4,24h, 48,72h, the successive administration group before administration every day and after the last administration 1,2,4,24,48 and 72h eye checked and given a mark.Single and continuous 14 days eye drips as a result, the irritant reaction situation score value of animal eye cornea, iris and conjunctiva is 0, does not have any irritation and occurs, and the results are shown in Table 1.

Ophthalmic preparation is very high to the requirement of osmotic pressure, hyperosmotic solution absorbs moisture within the eye easily, make eye dryness and discomfort, hypisotonic solution then can make keratectasia and produce pain, we guarantee that by the selection to osmotic pressure regulator the osmotic pressure of bromfenac sodium gel for eye use is equivalent to 0.9%NaCl solution osmotic pressure, ooze state with tear formation etc., to reduce the stimulation of eye and to promote that medicine is absorbed better.
Aseptic requirement is one of the important quality of ophthalmic preparation and security requirement, in process of the present invention by adding suitable antibacterial and sterilizing, adopt direct inoculation to carry out 14 days steriling tests and the method for inspection is verified that strict control reaches the aseptic requirement of ophthalmic preparation.
PH characteristic according to the bromfenac sodium gel for eye use, the phosphate buffered solution of selecting pH=7.4 is as its release medium, mucosa characteristic according to eye, select the semipermeable membrane bag filter of molecular cut off 14000 to make simulation test, product sodium bromophenolate eye drops with 6 prepared samples of embodiment of the present invention and prior art is done contrast, the result is in identical release medium, contrast release test with eye drop in the bag filter shows that both in-vitro release are close, but the release of gel will be a little less than eye drop in the dispose procedure, and it is slower that release descends, and demonstrates the gel advantage of slow release effect in the long similar ophthalmic preparation of retention time within the eye.The results are shown in Table 2 and accompanying drawing.
