     When the aqueous composition contains timolol or a salt thereof or a solvate of timolol or the salt thereof as a β blocker, the pH value is preferably 6.5 or lower. 
     As disclosed in Test Examples 7 and 8 below, it was found that, while preservation of the aqueous composition containing the compound represented by Formula (1) or a salt thereof or a solvate of the compound or the salt thereof and timolol or a salt thereof or a solvate of timolol or the salt thereof at high temperature over a long period results in decomposition of timolol to form a degradation product, setting the pH value of the aqueous composition to 6.5 or lower suppresses the decomposition of timolol to achieve stabilization, and setting the pH value to a further lower value further stabilizes the compound represented by Formula (1) or a salt thereof or a solvate of the compound or the salt thereof in addition to timolol. 
     As used herein, the “pH value” means a value obtained by measuring the pH of the aqueous composition at a temperature of 25° C. While the pH value is preferably 6.5 or lower, from the viewpoint of the stability of timolol or a salt thereof or a solvate of timolol or the salt thereof, and in addition the stability of the compound represented by Formula (1) (preferably ripasudil) or a salt thereof or a solvate of the compound or the salt thereof, the pH value is more preferably 6.0 or lower, still more preferably 5.5 or lower, even more preferably 5.0 or lower, and particularly preferably 4.5 or lower. 
     The means to adjust the pH value of the aqueous composition is not particularly limited, and those skilled in the art could appropriately adjust the pH value by adjusting the type and amount of each component (pH regulator, for example) to be incorporated while checking the pH value. 
     The aqueous composition is preferably stored in a container, from the viewpoint of preservation stability and portability, and the like. As used herein, the “container” means a package for directly storing the aqueous composition. The container is a concept that includes all of the “well-closed container”, “tight container”, and “hermetic container” defined in the General Notices in the Japanese Pharmacopoeia 16 th  Edition. 
     The form of the container is not particularly limited as long as it can store an aqueous composition, and may be selected or set as appropriate, depending on the dosage form, for example. Specific examples of such containers include containers for injections, containers for inhalations, containers for sprays, bottle-shaped containers, tubular containers, containers for eye drops, containers for nasal drops, containers for ear drops, and bag containers. The container may be further packaged in a box, a bag, or the like. 
     The material of the container is not particularly limited, and may be selected as appropriate depending on the form of the container. Specific examples of materials include glass, plastics, cellulose, pulp, rubber, and metals, and preferably a plastic from the viewpoint of processability, squeezability, and durability. The resin for a container made of a plastic is preferably a thermoplastic resin. Examples of such resins include polyolefin-based resins such as low-density polyethylene (including linear low-density polyethylene), high-density polyethylene, medium-density polyethylene, polypropylene, and cyclic polyolefins; polyester-based resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, polybutylene naphthalate, and poly(1,4-cyclohexylene dimethylene terenaphthalate); polyphenylene ether-based resins; polycarbonate-based resins; polysulfone-based resins; polyamide-based resins; polyvinyl chloride resins; and styrene-based resins. A mixture of these resins (polymer alloy) may also be used. 
     While the material of the container is not particularly limited, from the viewpoint of discoloration-reducing action, it is preferably a polyolefin-based resin, and particularly preferably polypropylene. As described in Test Examples below, discoloration is particularly prominently reduced in the case of a container made of polyolefin-based resin. 
     As used herein, the “container made of polyolefin-based resin” means a container in which at least a portion that contacts the aqueous composition is “made of polyolefin-based resin”. Accordingly, a container in which, for example, a polyolefin layer is provided as the inner layer that contacts the aqueous composition and a different resin material or the like is, for example, laminated on the outer side of the inner layer also corresponds to the “container made of polyolefin-based resin”. The polyolefin-based resin is not particularly limited herein, and may be a polymer of a single monomer (homopolymer) or a copolymer of a plurality of monomers (copolymer). In the case of a copolymer, the mode of polymerization is not particularly limited, and may be random polymerization or block polymerization. Further, the stereoregularity (tacticity) of the polyolefin-based resin is not particularly limited. 
     Specific examples of such polyolefin-based resins include&#39; polyethylene (more specifically, such as low-density polyethylene (including linear low density polyethylene), high-density polyethylene, and medium-density polyethylene), polypropylene, cyclic polyolefins, poly(4-methylpentene), polytetrafluoroethylene, ethylene-propylene copolymer, ethylene-α-olefin copolymer, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-vinylacetate copolymer, and ethylene-ethyl acrylate copolymer. These polyolefin-based resins can be used singly or in combination of two or more. As the polyolefin-based resin, polyethylene, polypropylene, or a cyclic polyolefin is preferred, and polyethylene or polypropylene is more preferred, and polypropylene is particularly preferred, from the viewpoint of reducing the discoloration. 
     As used herein, the expression “made of polyolefin-based resin” means that the polyolefin-based resin is included in at least a portion of the material, and “made of polyolefin-based resin” also includes, for example, a mixture of two or more resins (polymer alloy), which are a polyolefin-based resin and other resins. 
     A substance that prevents transmission of ultraviolet light, such as an ultraviolet absorber or an ultraviolet scattering agent, is preferably further mixed into the container made of polyolefin-based resin.

     When a substance that prevents transmission of ultraviolet light is mixed into the container, the proportion of the substance to be incorporated varies depending on the type of the substance and the like, but it may be 0.001 to 50 mass %, for example, preferably 0.002 to 25 mass %, and particularly preferably about 0.01 to 10 mass %, in the container. 
     The inside of the container is preferably visible (observable) by the naked eye. When the inside is visible, the following advantages are produced. For example, the presence or absence of any foreign matter can be inspected in the manufacturing steps of the pharmaceutical preparation, and the residual amount of the contents (aqueous composition) can be examined by a user of the pharmaceutical preparation. The visibility may be ensured in at least a portion of the surface of the container (for example, even if the side surface of a container for eye drops cannot be seen through due to the presence of a shrinkable film or the like, it can be determined that the inside is visible if the bottom surface of the container is visible). If the inside is visible through a portion of the surface of the container, then the aqueous composition in the container is visible. 
     The means for storing the aqueous composition into the container is not particularly limited, and the container may be filled with the aqueous composition using a conventional method, in accordance with the form of the container and the like. 
     The disease targeted by the aqueous composition or the pharmaceutical preparation is not particularly limited, and may be selected as appropriate depending on the pharmacological action or the like of the compound represented by Formula (1). 
     Specifically, the aqueous composition or pharmaceutical preparation can be used, for example, as a prophylactic or therapeutic agent for ocular hypertension or glaucoma, based on the Rho kinase inhibitory action or intraocular pressure-lowering action of the compound represented by Formula (1), and the intraocular pressure-lowering action of the β blocker. This is preferred because the intraocular pressure-lowering action of the compound represented by Formula (1) and the intraocular pressure-lowering action of the β blocker are combined to produce excellent intraocular pressure-lowering action, which leads to achievement of excellent prophylactic and/or therapeutic action for ocular hypertension or glaucoma. More specifically, examples of types of glaucoma include primary open-angle glaucoma, normal-tension glaucoma, hypersecretion glaucoma, acute closed-angle glaucoma, chronic closed-angle glaucoma, plateau iris syndrome, combined mechanism glaucoma, steroid-induced glaucoma, capsular glaucoma, pigmentary glaucoma, amyloid-associated glaucoma, neovascular glaucoma, and malignant glaucoma. 
     Further, as disclosed in JP-B-5557408, the pharmaceutical preparation may be used as a prophylactic or therapeutic agent for ocular fundus diseases (lesions that mainly develop in the retina and/or choroidea; specifically, for example, hypertensive or arteriosclerotic ocular fundus abnormalities, central retinal artery occlusion, retinal vein occlusion such as central retinal vein occlusion or branch retinal vein occlusion, diabetic retinopathy, diabetic macular edema, diabetic maculopathy, Eales disease, congenital retinal vascular abnormalities such as Coats disease, von Hippel disease, pulseless disease, macular diseases (such as central serous chorioretinopathy, cystoid macular edema, age-related macular degeneration, macular hole, myopic macular degeneration, vitreoretinal interface maculopathy, drug-related maculopathy, or heredomacular degeneration), retinal detachment (such as rhegmatogenous, tractional and exudative, or the like), retinitis pigmentosa, or retinopathy of prematurity) based on the action of the compound represented by Formula (1). More preferably, the pharmaceutical preparation may be used as a prophylactic or therapeutic agent for diabetic retinopathy, diabetic macular edema, or age-related macular degeneration. 
     When the aqueous composition or pharmaceutical preparation is used as a prophylactic and/or therapeutic agent for an eye disease (preferably, a disease selected from the group consisting of ocular hypertension, glaucoma, and ocular fundus diseases, particularly preferably a disease selected from the group consisting of ocular hypertension and glaucoma), the aqueous composition or pharmaceutical preparation may be administered about one to three times per day. 
     EXAMPLES 
     The present invention will be described next in more detail with reference to examples; however, the invention is in no way limited to these examples. 
     In the following test examples, ripasudil monohydrochloride dihydrate can be produced in accordance with the method described in WO2006/057397, for example. 
     Test Example 1 
     Preservation Test 
     Aqueous compositions of Example I and Comparative Example 1 containing the components in the quantities per 100 mL shown in Table 1 were prepared in accordance with a conventional method, and each stored in a container made of polypropylene. 
     The resulting aqueous compositions were preserved at 80° C. for 1 week. The degree of discoloration (yellowing) after the preservation was evaluated by measuring the color difference (ΔYI) of the aqueous compositions before and after the preservation using a color difference meter (spectrophotometer, CM-700d: Konica Minolta Sensing, Inc.). 
     The results are shown in Table 1.

     As shown in the results set forth in Table 1, it was revealed that when carteolol is further incorporated in the aqueous composition containing ripasudil, the ΔYI value is significantly lowered in comparison with the case where the aqueous composition does not contain carteolol, and discoloration after high-temperature preservation is reduced. 
     The foregoing test results revealed that when a β blocker typified by carteolol is further incorporated in the aqueous composition containing the compound represented by Formula (1) typified by ripasudil or a salt thereof or a solvate of the compound or the salt thereof, discoloration (yellowing) is relatively unlikely to occur even after preservation at high temperature, and excellent preservation stability can be achieved. 
     Test Example 2 
     Preservation Test No. 2 
     Aqueous compositions of Example 2 and Comparative Example 2 containing the components in the quantities per 100 mL shown in Table 2 were prepared in accordance with a conventional method. 
     Each of the resulting aqueous compositions was preserved at −5° C., during which the presence or absence of crystal precipitation was visually evaluated periodically to determine for which aqueous composition earlier crystal precipitation would be observed. The aqueous composition for which earlier crystal precipitation was not observed was rated as “b”, and the aqueous composition for which earlier crystal precipitation was observed was rated as “d”. 
     The results are shown in Table 2.

     As shown in the results set forth in Table 3, it was revealed that when timolol is further incorporated in the aqueous composition containing ripasudil, crystal precipitation during low-temperature preservation is suppressed in comparison with the case where the aqueous composition does not contain timolol. 
     Test Example 4 
     Preservation Test No. 4 
     Aqueous compositions of Example 4 and Comparative Example 4 containing the components in the quantities per 100 mL shown in Table 4 were prepared in accordance with a conventional method. 
     Each of the resulting aqueous compositions was preserved at −5° C., during which the presence or absence of crystal precipitation was visually evaluated periodically to determine for which aqueous composition earlier crystal precipitation would be observed. The aqueous composition for which earlier crystal precipitation was not observed was rated as “b”, and the aqueous composition for which earlier crystal precipitation was observed was rated as “d”. 
     The results are shown in Table 4.

     As shown in the results set forth in Table 4, it was revealed that when nipradilol is further incorporated in the aqueous composition containing ripasudil, crystal precipitation during low-temperature preservation is suppressed in comparison with the case where the aqueous composition does not contain nipradilol. 
     The foregoing results of Test Examples 2 to 4 revealed that when a β blocker typified by carteolol, timolol, and nipradilol is further incorporated in the aqueous composition containing the compound represented by Formula (1) typified by ripasudil or a salt thereof or a solvate of the compound or the salt thereof, precipitation of crystals is relatively unlikely to occur even after preservation at low temperature, and excellent preservation stability can be achieved.

     As shown in the results set forth in Table 5, no crystal precipitation was observed for the aqueous compositions of Examples 5 to 9 even after preservation at −5° C. for 1 month. 
     The foregoing results of Test Example 5 revealed that when an amino compound typified by L-glutamic acid, taurine, monoethanolamine, epsilon-aminocaproic acid, and trometamol is further incorporated in the aqueous composition containing the compound represented by Formula (1) typified by ripasudil or a salt thereof or a solvate of the compound or the salt thereof and a β blocker typified by timolol or a salt thereof or a solvate of timolol or the salt thereof, precipitation of crystals is relatively unlikely to occur even after preservation at low temperature over a long period, and excellent preservation stability can be achieved. 
     Test Example 6 
     Preservation Test No. 6 
     An aqueous composition was prepared in the same manner as was the aqueous composition of Example 5 except that 0.005 g of dibutylhydroxytoluene and 0.05 g of polysorbate 80 were used in place of L-glutamic acid, and was preserved at −5° C. 
     After preservation for 1 month, the presence or absence of crystal precipitation was visually evaluated, and no crystal precipitation was observed. 
     Test Example 7 
     Preservation Test (Evaluation of Stability of Timolol) 
     Aqueous compositions containing the components in the quantities per 100 mL shown in Table 6 and having a pH value of 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, or 8.0 at 25° C. were prepared in accordance with a conventional method. The pH value of each aqueous composition was adjusted through the amount of hydrochloric acid or sodium hydroxide incorporated. 
     Each of the resulting aqueous compositions having different pH values was preserved at 60° C. for 1 month, and the amount of a degradation product of timolol after the preservation was measured. The amount of a degradation product of timolol was determined as the area percentage (%) relative to the peak area derived from timolol and a degradation product thereof, using an HPLC apparatus. 
     The results are shown in Table 7.

     As shown in the results set forth in Table 7, it was revealed that, in the aqueous composition containing ripasudil and timolol, timolol is stable in an environment of pH 6.5 or lower, and the amount of the degradation product decreases as the pH value is lowered until the pH reaches 5.5, and in contrast timolol is unstable over pH 6.5, and the amount of the degradation product increases as the pH value is elevated. 
     The pH value of an aqueous composition containing timolol singly (eye drop) is typically set to around 7.0 (for example, Timoptol eye drop: Santen Pharmaceutical Co., Ltd., RYSMON Ophthalmic Solution: Wakamoto Pharmaceutical Co., Ltd., and TIMOLATE Ophthalmic Solution: Nitten Pharmaceutical Co., Ltd.). However, it was revealed that it is preferred to set the pH value of the aqueous composition containing ripasudil and timolol to a pH value lower than around 7.0 from the viewpoint of the stability of timolol. 
     The foregoing test results revealed that when the pH value of the aqueous composition containing the compound represented by Formula (1) typified by ripasudil or a salt thereof or a solvate of the compound or the salt thereof and timolol or a salt thereof or a solvate of timolol or the salt thereof at 25° C. is set to 6.5 or lower, timolol or a salt thereof or a solvate of timolol or the salt thereof can be stabilized. 
     Test Example 8 
     Preservation Test (Evaluation of Stability of Ripasudil) 
     Aqueous compositions containing the components in the quantities per 100 mL shown in Table 6 and having a pH value of 4.0, 4.5, 5.0, 5.5, 6.0, or 6.5 at 25° C. were prepared in the same manner as in Test Example 7. 
     Each of the resulting aqueous compositions having different pH values was preserved at 60° C. for 1 month, and the amount of a degradation product of ripasudil after the preservation was measured. The amount of a degradation product of ripasudil was determined as the area percentage (%) relative to the peak area derived from ripasudil and a degradation product thereof, using an HPLC apparatus. 
     The results are shown in Table 8.
