TECHNICAL FIELD Means for Solving the Problems 15 The present inventors made intensive studies on the effect The present invention relates to a preventive ortherapeutic of a combination of preventive or therapeutic agents for glau agent for glaucoma or ocular hypertension, or an intraocular coma or ocular hypertension, and as a result, they found that pressure lowering agent comprising a combination of by combining isopropyl (6-4-(pyrazol-1-yl)benzyl (pyri isopropyl (6-4-(pyrazol-1-yl)benzyl (pyridin-3-ylsulfo din-3-ylsulfonyl) aminomethylpyridin-2-ylamino)acetate nyl)aminomethylpyridin-2-ylamino) acetate with other pre with other preventive or therapeutic agent for glaucoma or ventive or therapeutic drug for glaucoma or ocular hyperten ocular hypertension, the intraocular pressure lowering effect S1O. is enhanced as compared with the case where each agent is used singly, and thus completed the invention. That is, the BACKGROUND ART invention relates to the following aspects. 25 (1) A preventive or therapeutic agent for glaucoma or Glaucoma is an intractable ocular disease with a risk of ocular hypertension, comprising a combination of isopropyl blindness, involving an increase in intraocular pressure due to (6-4-(pyrazol-1-yl)benzyl (pyridin-3-ylsulfonyl) various predisposing factors and the disorder of internal tis aminomethylpyridin-2-ylamino)acetate with one or more Sues of eyeballs (retina, an optic nerve, and the like). Agen other preventive or therapeutic drugs for glaucoma or ocular eral method of treating glaucoma is intraocular pressure low 30 hypertension (with the proviso that tafluprost is excluded). ering therapy, which is exemplified by pharmacotherapy, (2) An intraocular pressure lowering agent, comprising a laser therapy, surgical therapy, and the like. combination of isopropyl (6-4-(pyrazol-1-yl)benzyl (pyri In the pharmacotherapy, a drug Such as a sympathomimetic din-3-ylsulfonyl)aminomethylpyridin-2-ylamino)acetate drug (a nonselective stimulant such as diplivefrin oran O-re with one or more other preventive or therapeutic drugs for ceptoragonist Such as brimonidine), a sympatholytic drug (a 35 glaucoma or ocular hypertension (with the proviso that taflu B-receptor antagonist Such as timolol, befunolol, carteolol. prost is excluded). nipradillol, betaxolol, levobunolol or metipranolol, or an (3) The preventive or therapeutic agent or the intraocular C-receptor antagonist Such as bunaZosin hydrochloride), a pressure lowering agent according to the above (1) or (2), parasympathomimetic drug (such as pilocarpine), a carbonic wherein the other preventive ortherapeutic drug for glaucoma anhydrase inhibitor (such as acetazolamide), a prostaglandin 40 or ocular hypertension (with the proviso that tafluprost is (such as isopropyl unoprostone, latanoprost, travoprost or excluded) is one or more preventive or therapeutic agents bimatoprost) is used. Further, Rho-kinase inhibitors (such as selected from the group consisting of a nonselective sym SNJ-1656), adenosine agonists (such as INO-8875), seroto pathomimetic drug, an O2-receptor agonist, an O-receptor nin antagonists (BVT-28949), and the like have been under antagonist, a B-receptor antagonist, a parasympathomimetic development as novel drugs. Other than these, a prostaglan 45 drug, a carbonic anhydrase inhibitor, a prostaglandin and a din E2 receptor Subtype 2 agonist (EP2 agonist) is known to Rho-kinase inhibitor. have an intraocular pressure lowering effect, and it is reported (4) The preventive or therapeutic agent or the intraocular in WO 2010/113957 that a sulfonamide compound having pressure lowering agent according to the above (3), wherein high EP2 receptor selectivity and a potent EP2 agonistic the nonselective sympathomimetic drug is diplivefrin. activity is promising as a therapeutic drug for glaucoma. 50 (5) The preventive or therapeutic agent or the intraocular There are several reports of the combined use of drugs pressure lowering agent according to the above (3) or (4), having an intraocular pressure lowering effect to treat glau wherein the C-receptor agonist is brimonidine or apracloni coma. For example, Japanese Patent No. 2726672 reports the dine. combined administration of a sympatholytic drug with a pros (6) The preventive or therapeutic agent or the intraocular taglandin.

WO (7) The preventive or therapeutic agent or the intraocular 2004/019951 reports the combined administration of a Rho pressure lowering agent according to any one of the above (3) kinase inhibitor with a prostaglandin, and WO 2004/045644 to (6), wherein the B-receptorantagonist is timolol, befunolol. reports the combined administration of a Rho-kinase inhibi 60 carteolol, nipradillol, betaxolol, levobunolol or metipranolol. tor with a B-receptor antagonist. (8) The preventive or therapeutic agent or the intraocular However, there have been no reports specifically disclosing pressure lowering agent according to any one of the above (3) a combination of isopropyl (6-4-(pyrazol-1-yl)benzyl (py to (7), wherein the parasympathomimetic drug is pilocarpine. ridin-3-ylsulfonyl)aminomethylpyridin-2-ylamino)acetate, (9) The preventive or therapeutic agent or the intraocular which has a high EP2 receptor selectivity and a potent EP2 65 pressure lowering agent according to any one of the above (3) agonistic activity, with other preventive or therapeutic drug to (8), wherein the carbonic anhydrase inhibitor is dorzola for glaucoma or ocular hypertension, and naturally, it has not mide, brinzolamide or acetazolamide.
