Definitions
- platelet aggregation inhibitors such as acetylsalicylic acid and drugs that improve erythrocyte deformability are currently prescribed.
- vasodilators In order to generally improve the blood circulation in blood vessels, vasodilators can be administered systemically. However, it has been shown that systemic administration of vasodilators cannot achieve a long-term improvement in the blood flow in the optic nerve and retina in the normotonic, unlike in the hypertensive. There are also test results that show that a therapeutically increased blood flow in other body regions in the eye area can lead to reduced blood flow. Diabetes mellitus is a disease that can lead to poor blood circulation in the eye. Diabetes mellitus can lead to diabetic retinopathy. Diabetic retinopathy can lead to blindness in the diabetic. In the course of the development of diabetic retinopathy, there is reduced blood flow and insufficient oxygen supply to the retina.

- the papaverine-like vasodilators are also called musculotropic spasmolytics.
- the papaverine-like vasodilators relax the muscles by acting directly on the smooth muscle cells.
- papaverine-like vasodilators are understood to be isoquinoline derivatives which, as a common structural element, have an isoquinoline ring system and have a vasodilatory effect.
- the papaverine-like vasodilators have in vitro relaxing effects on smooth muscle organs including arterial vessels.
- the effects of the papaverine-like vasodilators are attributed to an inhibition of phosphodiesterase (PDE) and a consequent increase in cyclic AMP in muscle cells.
- PDE phosphodiesterase
- the papaverine-like vasodilator is selected from the group consisting of papaverine, ethaverine, moxaverine, elziverine, their pharmacologically acceptable salts and mixtures thereof.
- the structural formulas of the aforementioned compounds are given below: Papaverine (6,7-dimethoxy-1-veratrylisoquinoline):
- All of the aforementioned active ingredients can be used as a free base or as a pharmacologically acceptable salt thereof, for example as hydrochloride, sulfate, amidosulfate, etc.
- the active ingredients can be in the form of acid addition salts.
- the following salts for example, have proven suitable: papaverine hydrochloride, papaverine sulfate, ethaverine hydrochloride, ethaverine amido sulfate, moxaverine hydrochloride, elziverine hydrochloride.
- other pharmacologically acceptable salts of the aforementioned active ingredients or mixtures thereof can also be used.
- Moxaverin or moxaverin hydrochloride have proven to be very suitable.

- the papaverine-like vasodilators preferably papaverine, ethaverine, moxaverine, elziverine, their pharmacologically acceptable salts and mixtures thereof, have a local relaxing effect on the blood vessels of the eye after topical application to the surface of the eye.
- This novel, ophthalmic use of the above-mentioned active ingredients thus avoids the undesirable effect on all blood vessels of the organism when vasodilators are administered systemically.
- the blood vessels in the eye are selectively dilated and the blood flow to the eye is improved.
- the expansion of the blood vessels in the eye improves the microcirculation and thus improves the supply of nutrients and oxygen to the eye via the blood.
- the use according to the invention extremely advantageously permits the treatment of ophthalmological malfunctions which are connected with circulatory disorders of the eye or are to be attributed to circulatory disorders of the eye.
- the ophthalmic malfunctions are selected from the group consisting of glaucoma, ophthalmic malfunctions associated with diabetes, for example neovascular glaucoma, hemorrhagic glaucoma or diabetic retinopathy.
- the pharmaceutical composition is to be applied topically to the eye.
- the pharmaceutical composition is in the form of eye drops, eye ointment, eye spray, eye tablets, gel, suspension, emulsion, powder or granules.
- the active substances can be dissolved or suspended in the buffer solutions used in the customary manner, such as, for example, phosphate buffer, acetate buffer, acetate-borate buffer, borate buffer, citrate buffer, etc.
- the active ingredients for application to the eye do not have to be in dissolved or completely dissolved form. Rather, it is sufficient if the active ingredients are in suspension.
- the active ingredients are absorbed by the eye from the suspension applied to the surface of the eye.

- the viscosity-increasing effect has the extremely advantageous effect that the pharmaceutical composition applied to the surface of the eye has an increased residence time and does not flow off the surface of the eye again.
- a very suitable viscosity regulator is hyaluronic acid or its salts.
- Potassium, sodium, calcium and / or magnesium hyaluronates, for example, can be used as salts of hyaluronic acid.
- the hyaluronate is preferably sodium hyaluronate.
- Hyaluronic acid or hyaluronate are structurally similar to mucin, the bottom layer of the three-layer tear film, and ensure optimal wetting of the corneal and conjunctival parts.
- the hyaluronic acid and / or the hyaluronate thus imitates the mucus phase of the tear film and thus extends the length of time of the applied active ingredient on the eye, since the viscosity counteracts drainage.
- the non-Newtonian flow behavior of the hyaluronic acid or the hyaluronates requires an excellent property for use on the eye, namely that the viscosity decreases with increasing shear rate.
- a shear stress is applied to the pharmaceutical composition via the blinking of the eyelid, whereby the initially increased viscosity is reduced.
- the blinking of the eyelid lowers the viscosity so that a uniform film is formed on the surface of the eye.
- the viscosity increases so that the film adheres well to the surface of the eye.
- hyaluronic acid or its salts as a viscosity regulator is extremely advantageous when it comes to visual impairment.
- the hyaluronic acid and / or the hyaluronate has a molecular weight in a range from about 50,000 to about 10,000,000 daltons, preferably from about 250,000 to about 5,000,000 daltons, more preferably between about 500,000 to 4,000,000 daltons more preferably between about 1,500,000 to 3,500,000 daltons.

- the papaverine-like vasodilator is selected from the group consisting of papaverine, ethaverine, moxaverine, elziverine, their pharmacologically acceptable salts and mixtures thereof.
- the viscosity regulator is selected from the group consisting of chondroitin sulfate, polyacrylamide, polyacrylic acid, polyacrylic resins, polyethylene glycol, cellulose derivatives, polyvinyl alcohol, polyvinylpyrrolidone, hyaluronic acid, hyaluronate and mixtures thereof.
- the pharmaceutical composition is in the form of eye drops, eye ointment, eye spray, eye tablets, gel, suspension, emulsion, powder or granules.
- the pharmaceutical composition is in dry form, for example as a powder or granules, it can be dissolved or suspended in a liquid carrier, for example a sterile buffer solution, immediately before application to the eye surface and then applied.
- a liquid carrier for example a sterile buffer solution
- the dosage of the papaverine-like vasodilators depends on the individual circumstances of the clinical picture to be treated and the person to be treated. If the circulatory disorders in the eye are detected at a very early stage, the dosage is lower than in an advanced stage of the disease.
- the amount of papaverine-like vasodilator contained in a unit dose to be administered to the eye can be between 0.001 mg / ml and 100 mg / ml, preferably between 0.1 mg / ml and 50 mg / ml, more preferably between about 0.5 mg / ml and 10 mg / ml.
- the active ingredient is preferably in the form of an acid addition salt.
- Acid addition salts are generally good or better water-soluble than the free base.
