Abstract

Ophthalmic compositions comprising an ophthalmic drug, e.g. ketotifen, and a linear polysaccharide compound, e.g. a hyaluronic acid compound, are useful for topical once-a-day administration to the eye.

Description

Contain hyaluronic eye medicine combination
The present invention relates to the method for the unusual or ophthalmic diseases of pharmaceutical composition, particularly eye medicine combination example gel, and applying said compositions treatment eye.
Eye medicine combination, (said composition is known, for example, is recorded in WO01/07049, and is available commercially, for example with trade (brand) name Zaditen for example to comprise the eye medicine combination of ketotifen Or Zaditor Obtain) use for several times, be generally two to four times the every day of having to usually.So administration repeatedly is unsatisfactory in actual use, because for example patient has to medicine is carried, but also can be disturbed for several times in one day because need to use medicine.Therefore, the multiple dosing of medicine, especially eye medicine combination tends to cause the excessive and/or insufficient problem of drug use.And the excessive stimulation that may cause eyes usually of drug use, the drug dose deficiency then may cause the recurrence of symptom usually.
So, the medicament for the eyes that need be administered once a kind of so-called every day.The present invention finds, can make the pharmaceutical composition that be administered once such every day, particularly eye medicine combination.Described compositions can provide their contained drugs, for example medicament for the eyes as the therapeutic effect of ketotifen about 24 hours at eye.Said composition has beat all well tolerable property, and produces very reliable and repeated fabulous clinical effectiveness in using the patient of said composition.
Therefore, on the one hand, the invention provides a kind of eye medicine combination, especially for topical every day compositions once, said composition comprises a kind of medicament for the eyes and a kind of linear polysaccharide chemical compound, preferred a kind of hyaluronic acid chemical compound (hereinafter referred to as compositions of the present invention).

Eye medicine combination of the present invention can prepare according to conventional method, for example: with medicament for the eyes and suitable mixed with excipients.
Compositions of the present invention is preferably transparent, and the solution of preferably clear or gel form are as transparent gel.
Filling can or be carried out after the sterilization before with the mixture sterilization of gained.The present composition and the sterilization of packing just can realize in order to method down, for example: gamma-rays radiation, with ethylene oxide treatment, with electron beam irradiation, autoclaving, microwave treatment, filter or steam sterilization with sterilizing filter.
The present composition can be packed according to conventional method.The present composition can be stored with single or multiple unit dosage forms, for example: airtight bottle, pipe or other container, these containers are by glass, plastics, and for example the combination of polyethylene, polyethylene terephthalate, polypropylene, metal or above material is made.For example, can contain in the bottle and have an appointment 1 to 5ml compositions of the present invention.Can load onto a dropper on the container so that administration.
Compositions of the present invention can be prepared with traditional mode, as is specially adapted to the mode of the topical of eyes.This not special description, these methods are known in the art for the method for preparation, and are perhaps similar with methods known in the art or method described herein.Representational method is documented in for example Remington ' s Pharmaceutical Sciences, and the 19th edition, Mack publishing house, 1995, H.Sucker etc.; Pharmazeutische Technologie, second edition, Thieme, 1991, R:H.Mueller etc.; Pharmazeutische Technologie:ModerneArzneimittelformen, second edition, Wissenschaftliche Verlagsgesellschaft, Stuttgart, 1998, L.Lachman etc.; The industrial principle of pharmacy and application (The Theory andPractice of Industrial Pharmacy), the third edition, 1986 and Hagers Handbuch derpharmazeutischen Praxis, the 4th edition the 7th volume, (Springer Verlag, 1971) and later version, above all the elements are all incorporated this paper into as a reference.
Used excipient can be for example known in the art those, for example be recorded in the following document those: Lexikon der Hilfsstoffe f ü r Pharmazie, Kosmetik und angrenzende Gebiete" handbook of pharmaceutical excipients ( Handbook of Pharmaceutical Excipients) ", the content of reference is referring to above; Or with the similar excipient of the known excipient in field, or have to prior art in or the new excipient of the similar function of excipient described herein.
Compositions of the present invention can be used for treating ophthalmic diseases/ophthalmic uncomfortable, concrete curative effect depends on the medicine that compositions is contained, for example show the infection that said composition can be treated inflammation, allergy, glaucoma, contracted pupil, numbness, be caused by virus, fungus or microorganism by standard animal experiment and clinical trial.Contain ketotifen and can be used for the temporary ophthalmic pruritus that causes by anaphylaxis conjunctivitis of preventing as the present composition of medicine, and the ophthalmic pruritus that causes of particularly seasonal anaphylaxis conjunctivitis, and, show that by standard animal and clinical trial it can be used for preventing and treating the sign and the symptom of seasonal anaphylaxis conjunctivitis.
An animal experiment is included in the Draize test of the improvement of carrying out on three albino rabbits, wherein, shows the toleration of eyes after 15 minutes and 1,2,7 day after the present composition of the dosage (50 μ L) that instils arrives ocular surface.Toleration is based on vision-based detection and consider following parameter: the turbidity of, chemosis (enlargement) rubescent, cornea and cornea relevant range by nictation or part/ophthalmic uncomfortable of judging of closing one's eyes fully, uncomfortable time, ejection, the conjunctiva (eyelid and bulbar conjunctiva) that continues, and the pathologic of iris changes.
Can carry out effect and the toleration of clinical trial with the test present composition, wherein, with 10 to 25 healthy volunteers or oculopathy or ophthalmic uncomfortable patient to be treated is the test crowd, be administered once in one day, the present composition that about 30 to 40 μ l are comprised 0.025% medicament for the eyes is instilled into eyeball surface at every turn, as the palpebra inferior inboard.Test duration 8 days.
By checking that the experimenter determines the curative effect to conjunctivitis, for example: the rapid onset of efficacy of a drug effect and permanent lasting and good tolerability for example significantly do not stimulate or redden.
In addition, bioavailability and the dosage form of commercially available one day administered twice of compositions of the present invention in above-mentioned test is suitable, and described bioavailability is to be determined by the absorption of conjunctiva or its surrounding tissue.
The bioavailability of the eye medicine combination that be administered once above-mentioned every day is measured by pharmacokinetic analysis described below:
With certain volume, for example the ophthalmic preparation of 50 μ l splashes into the top of rabbit conjunctiva.After 5,15,30 minutes or 1,8,16,20 hour, take a sample from conjunctiva, cornea, sclera.Extract sample to measure the ratio of medicine with respect to tissue wet.Medicament contg is by measuring with the liquid chromatograph (LC-MS) that links to each other with mass spectrograph.
Medicine, for example the definite consumption of ketotifen depends on numerous factors, for example the order of severity of the characteristic of the selection of salt, excipient, preparation and disease.Easily, compositions of the present invention can for example early be applied to cornea once a day after meal.Preferably use about 25 to 75 μ l, for example about 50 to 75 μ l for example use the dropper administration.
The daily dose of medicine depends on the kind and the indication of medicine.For example, ketotifen, the dosage of every kg body weight are approximately 1 approximately to 5 micrograms.For large mammal, the mammal of 70 kilogram weights people for example for example, recommended doses is about 100 to about 300 micrograms.
Therefore, the present invention provides on the other hand:
