Information about prior art
In its broadest sense, the term "cataract" determine any change in optical homogeneity or decrease the transparency of the eye lens. In the etiology of cataract involved many factors, such as heredity, aging, diabetes, Smoking, nutrition, the cumulative effect of x-ray and UV radiation, and the endocrine and/or enzymatic equilibrium in the body.
The most significant among the chemical compounds that cause cataracts are oxygen radical particles, for example, formed under the action of UV radiation present in the spectrum of sunlight. Such particles disturb the homeostasis of the lens by increasing the level of ions of CA2+in the lens, which, in particular, activates calciseptine protease, for example, calpain. This leads to the destruction of proteins in the crystalline lens, such as crystalline, and, ultimately, to its dimness.
The proposed mechanism is not the only, but allows you to choose the target DL the drugs and to develop treatment strategies. In particular, one of the famous and very safe antioxidants linking hydroxyl, peroxide, peroxynitrite radicals, is disulfiram - dimer of diethyldithiocarbamate, which itself also able to resolve the action of hydroxyl radicals and to inhibit lipid peroxidation. However, the low solubility of disulfiram in water, stable in neutral aqueous media and the inability to penetrate through the cornea are significant obstacles to its use in ophthalmology.
In the application EP 2238978 (publ. 13.10.2010) disclosed a pharmaceutical composition comprising an inclusion complex of disulfiram and cyclodextrin, optionally containing uncomplexed disulfiram and one or more pharmaceutically acceptable carriers. In embodiments of the invention disclosed liquid parenteral, preformed oral and palletirovaniya subcutaneous form of the drug for treatment of addiction to alcohol and cocaine, containing 15-80 wt.% complex disulfiram.

Vol.30(8) (2007). P.1529-1534, publ. 05.06.2007) in rat models ICR/f (line with cataracts inherited in recessive type) shows the following. To 77 day life of animals in the groups treated with eye drops containing di is ulyram, the lens opacity was 35-45% less expressed than in animals of the control group treated with isotonic saline solution, which is already 75 day life emerged clearly observed cataract. Experimental animals since the 30 days, twice a day was administered in the left eye 50 µl drops containing 0.25-to 0.50% of disulfiram, 3,0-5,0% 2-hydroxypropyl-β-cyclodextrin and 0.1% hydroxypropylmethylcellulose.
In article Nagai N., Ito Y., Takeuchi N. "Effect of Disulfiram Eye Drops on Lipid Peroxide Formation via Excessive Nitric Oxide in Lenses of Hereditary Cataract ICR/f Rats" (Biol. Pharm. Bull. Vol.31 (5) (2008). P.981-985, publ. 13.02.2008) shows that the introduction of droplets containing 0.25-to 0.50% of disulfiram, 3,0-5,0% 2-hydroxypropyl-β-cyclodextrin and 0.1% hydroxypropyl-methylcellulose to 77 day life of animals in 1,5-2 times pixel increases the level of transparency of the lens and in the same proportion reduces the content of ions of CA2+in the lens. In the lens 1.5 times reduced the concentration of NO and 2 times reduced the content of lipid peroxides.
The authors consider the results disclosed in both articles as the basis for further studies of such drugs disulfiram as a potential anti-cataract drugs, due to aging.
In article Nagai N., Ito Y., Takeuchi N. "Pharmacokinetic and Pharmacodynamic Evaluation of the Anti-cataract Effect of Eye Drops Containing Disulfiram and Low-Substituted Methylcellulose Using ICR/f Rat Lens as a Hereditary Catarat Model" (Biol. Pharm. Bull. Vol.35 (2) (2012). P. 239-245, publ. 24.11.2011) in rat models ICR/f shows that the introduction of eye drops containing 0.5% of disulfiram, 5% 2-hydroxy-propyl-β-cyclodextrin, 0.1% hydroxypropyl-methylcellulose, and 2.0% methylcellulose allows the time interval from 77 84-day life of a male model animals to maintain a pixel index of lens transparency, greater than 2-3 times the rate in the control group. It was also found that a preparation containing methylcellulose in the clinical concentration (2,0%), more effective than a similar product described in previous articles. The authors explain this fact by gelation with increasing temperature up to the temperature of the eye (about 35°C), which increases the retention time of eye drops on the surface of the cornea.
The prior art various ophthalmic preparations containing taurine. In the application EP 0778021 (publ. 11.06.1997) revealed eye drops to accelerate the regeneration of the cornea after injury, containing 0.5 to 3.0% taurine, sodium chloride, potassium chloride and sodium bicarbonate having a pH of from 5.5 to 8.0 and the osmotic pressure of from 250 to 450 mOsm.

At present a unified view of the causes and mechanisms of development of glaucoma are missing. Moreover, sometimes difficulties arise when attempting to define the term "glaucoma". Specialists comprise about 60 diseases of the eye, which has the following General features: continuous or periodic individually exceeded tolerance level of IOP, glaucomatous optic neuropathy, resulting in its final stages to atrophy of the optic nerve and is typical for glaucoma disorders of visual functions.
In the context of the invention, the term "glaucoma" refers to a chronic eye disease characterized by continuous or periodic increase in intraocular pressure (IOP) with the development of trophic disorders in the ways of outflow of aqueous fluid in the retina and in the optic nerve that causes the development of regional excavation of the optic disc and the appearance of typical defects in the field of view.
In the article, Ito Y., Nagai N., Shimomura Y. "Reduction in Intraocular Pressure by the Instillation of Eye Drops Containing Disulfiram Included with 2-Hydroxypropyl-β-cyclodextrin in Rabbit" (Biol. Pharm. Bull. Vol.33 (9) (2010). P.1574-1578, publ. 08.06.2010) on the model of ocular hypertension in rabbits caused by a rapid infusion of 5% solution of glucse shown that the introduction of eye drops containing 0.1-0.5% of disulfiram, 1,1-5,0% 2-hydroxypropyl-β-cyclodextrin and 0.1% hydroxyprop the Il-methylcellulose in the period of time from 5 to 30 minutes after induction of ocular hypertension, allows 10-30% reduction in IOP. The authors believe that the results give reason to believe investigated drugs are the basis for the development of antiglaucoma funds.
Article V. Ermakova. "The effectiveness of combination taufona with antiadrainergicakimi drugs in primary open-angle glaucoma" (Ross. the oft. Journe. No. 2 (2008). P.12-17) have shown that a combined application of taufona with timolol, practolol, proxophelinum and proccacia for a long time (up to 1 year) can only slightly reduce IOP, but sufficiently improves the outflow of aqueous humor.
Ocular hypertension is not a disease as such, but is a pathological condition of elevated intraocular pressure, which normally is within 10-21 mm Od. Persistent or recurrent ocular hypertension can cause not only the development of glaucoma, but also lead to other injuries of the eye, leading to vision loss, such as occlusion of the retinal vein and nglaucomatous the destruction layer of the optic nerve fibers [D.S. Minckler "Histology of optic nerve damage in ocular hypertension and early glaucoma". Surv. Ophthalmol. Vol.33 (April 1989). P.401-411].
In article Bunin YA, Yartseva H., Kolesnikova Y.A., Yermakova VN, Yakovlev A.A., Berdnikovoy T.A., Komleva N.A. "the Effect of taurine on intraocular pressure and blood-ophtalmic the ski barrier (experimental study [Matters. the oft. No. 1 (1978). S-24] on the model of prostaglandin hypertension in rabbits have shown that instillation of 4% solution of taurine delay time increased IOP and statistically reduces 2-5 mm Hg IOP experienced eyes during the whole experiment. Similar results were obtained in models of salt hypertension in the eyes of rhesus monkeys. Thus, taurine has a hypotensive effect on the intraocular pressure, which may be due to inhibition of secretion of aqueous humor.
However, there is a need for ophthalmic drugs with greater pharmacological activity.

Example 2. The study of therapeutic action on the model of traumatic cataract in rabbits
The study was conducted on 24 rabbits breed "Chinchilla" average weight of 3.5 kg age 3.5-4 months with a model of traumatic cataract.
Modeling of traumatic cataract performed on the right eye of all animals in the following way. After medical Misa called twice instillation in the conjunctival cavity 1%solution of pilocarpine hydrochloride with an interval of 15 minutes, to produce laser coagulation of the pigment portion of the pupil localization coagulates 1,5-2,0 mm outwards from the optical center of the lens in the Meridian 8-10 hours On the iris of each eye put 15-40 coagulates. The parameters of laser radiation pulse energy of 1.6 to 2.2 W, pulse duration of 0.6 seconds. Delivery of laser radiation carried through the head binocular Ophthalmoscope.
In accordance with the objectives of the study all animals are divided into 3 groups (table 2).
|Group||The drug and dosage||The number of animals (eyes)|
|1||Preparation 2 according to the invention; 1 mg/kg rabbit 1 time per day subkonyunktivalno within 10 days.||6 (6)|
|2||"Taufon, eye drops 4%"; 1 mg/kg rabbit 1 time per day subkonyunktivalno within 10 days.||6 (6)|
|3||Water for injection of 0.3 ml rabbit 1 time per day subkonyunktivalno within 10 days.||6 (6)|
In the first week biomicroscopy of the eye lens and the study of its transparency spend every day, and in the future - weekly in transmitted light using a slit lamp SL-2B and head binocular microscope (NBO-2) using the Ophthalmoscope lenses of different optical power.
In addition, all rabbits immediately after cataract simulation, as well as after 1 and 2 months of therapy compared drugs are photography nature of cataract using the apparatus "Retcam-2" (production of Massive Research, USA). The results of dynamic monitoring of rabbits entered in a special registration card.
After 30 minutes of laser treatment of pigmented rim La CCA in the ground causing the laser coagulates acquires a milky white color. On the second day of the experiment, the pupil acquires former size and exposes the Department of the lens subjected to laser radiation. It is an area of intensive clouding of the capsule and anterior cortical lens layers in a u shape (projection pigmented rims constricted pupil at the time of laser irradiation). This thin plot of turbidity, follow the contour of the edge of the pupil, surrounded by a halo subcapsular vacuoles and sites growing dimness, not extending more than 1.5 mm from the basic "outline" of the dimness.
Starting from the third or fourth day the turbidity of the considered sections of the lens reaches the maximum intensity, depth and area, and is stabilized. The trend to reverse (very minor) traumatic cataract development gains since the 30th day of the experiment. However, even after 60 days of treatment of the studied drugs in any case not showed complete regression of cataract.
Size of the lens opacity is determined using a micrometer grid imposed on the full-sized image of the lens performed using apparatus "Retcam-2", according to the formula:
where S is the area of opacity mm2; N is the number of millimeter squares, fully "employed" clouding; n - the number is about a millimeter squares, partially "employed" by the dimness.
The severity of lens opacity assessed on a four point scale: 0 for full transparency of the lens; "1" - a gentle blackvideo turbidity; "2" - pronounced turbidity, for which, however, could be weakened by the fundus of the eye reflex; "3" - intense dense cataract in the absence in his projection of the fundus of the eye reflex. Due to the fact that cataract heterogeneous, calculate the average coefficient of turbidity by multiplying the intensity of the turbidity in each plot on its area, followed by summing and dividing by the total area of the dimness.
The results of dynamic monitoring of rabbits in groups shown in table 1, are presented in table 3.
|n||The monitoring phase|
|30 days||60 day|
|Size, mm2||Severity||Size, mm2||Severity||1||6||5,3±0,5||2,5±0,3||4,5±0,5||2,0±0,2|
In the study of the effectiveness of animal therapy found that both the investigational product have a significant positive impact on the clinical course of experimental traumatic cataract. So, after 1 month of treatment in all animals receiving the compared drugs, has been a steady trend towards the reduction of the size and intensity of cataract. While the changes primarily affect areas vacuolization and "secondary" opacities in the anterior and anterior subcapsular cortical layers of the lens.
The drug in accordance with the invention according to a survey on the 30th day of the experiment was slightly, but statistically significantly more effective is h, what is the drug "Taufon, eye drops 4%". In the control group 3 size, depth and intensity of turbidity remained more stable than in animals treated with therapy.
According to the results of further observations of rabbits, conducted in the period from 30 on the 60th day of the experiment, has more than a slight tendency to reverse the development of pathological changes in the lens (area, depth and intensity of turbidity), especially in group 1 treated with drug therapy in accordance with the invention.
