Definitions
- the present invention is a pharmaceutical preparation for treating or preventing glaucoma or ocular hypertension containing sepetaprost as an active ingredient, which is administered to a patient to whom another therapeutic agent for glaucoma or ocular hypertension is inadequately effective. Regarding.
- Glaucoma is an intractable eye disease in which the intraocular pressure rises due to various etiologies and the internal tissues of the eyeball (retina, optic nerve, etc.) are damaged, which may lead to blindness.
- intraocular pressure lowering therapy is common, and typical examples thereof include drug therapy, laser therapy, and surgical therapy.
- Drug therapy includes sympathomimetics (non-selective stimulants such as dipibefurin, ⁇ 2 receptor agonists such as brimonidine), sympathomimetics (timolol, befnorol, carteolol, niprazilol, betaxolol, levobnorol, methiprano).
- sympathomimetics non-selective stimulants such as dipibefurin, ⁇ 2 receptor agonists such as brimonidine
- sympathomimetics timolol, befnorol, carteolol, niprazilol, betaxolol, levobnorol, methiprano.
- Beta-blockers such as timololol, ⁇ - 1 -receptor blockers such as brimonidine hydrochloride), parasympathomimetics (pyrocarpine, etc.), carbonate dehydration enzyme inhibitors (acetazolamide, etc.), prostaglandins (isopropylunono) Drugs such as proston, latanoprost, travoprost, bimatoprost, etc.) and Rho kinase inhibitors (lipasdil) are used.
- Sepetaprost has the formula (1). It is a compound represented by, and is described as one of a huge number of compounds in Patent Document 1. It has been described that these compounds can be therapeutic agents for glaucoma because they have a strong and continuous effect of lowering intraocular pressure.
- Sepetaprost exhibits an excellent intraocular pressure lowering effect on patients for whom other therapeutic agents for glaucoma or ocular hypertension are inadequately effective, and completed the present invention.
- rice field Specifically, the present invention provides the following.
- a pharmaceutical preparation containing sepetaprost as an active ingredient for treating or preventing glaucoma or ocular hypertension which is administered to a patient to whom another therapeutic drug for glaucoma or ocular hypertension is inadequately effective.
- the intraocular pressure is further lowered by the active ingredient to reduce the glaucoma or ocular.
- a pharmaceutical preparation wherein the ocular hypertension is ocular hypertension resistant to the treatment of ocular hypertension with the other active ingredient.
- a method for treating or preventing glaucoma or ocular hypertension which comprises administering to a patient a pharmaceutical preparation containing sepetaprost as an active ingredient, wherein the other glaucoma or ocular hypertension therapeutic agent is insufficiently effective for the patient. Patient, how.
- the intraocular pressure is further lowered by the active ingredient to reduce the glaucoma or ocular.
