SANTEN PHARMACEUTICAL CO., LTD.

A method for stabilizing a composition for ophthalmic use containing sepetaprost is disclosed. More specifically, a method that facilitates retention of sepetaprost stability at high temperatures, and further, a method that facilitates the retention of preservative effectiveness of the composition for ophthalmic use are disclosed. The composition for ophthalmic use contains sepetaprost at a concentration of 0.0001 to 0.003% (w/v) and has a pH within a range from 5 to 8.

Disclosed herein is an aqueous composition comprising 0.001-0.1% (w/v) atropine or a salt thereof, a water-soluble polymer, and buffer (I), which is at a pH range of 6 or lower, wherein the buffer (I) is at least one selected from the group consisting of a phosphate buffer, an aminocarboxylate buffer, a carbonate buffer, an acetate buffer, a tartrate buffer, a borate buffer, and trometamol.

The purpose of the present invention is to provide a pharmaceutical composition that comprises a specific compound and exhibits a superior preservation efficacy, the specific compound being stable within the pharmaceutical composition, and to provide methods for improving the stability of the specific compound within the pharmaceutical composition and the preservation efficacy of the pharmaceutical composition. The pharmaceutical composition according to the present invention comprises isopropyl (6-{[4-(pyrazol-1-yl)benzyl](pyridin-3-ylsulfonyl)aminomethyl}pyridin-2-ylamino)acetate or a salt thereof, and further comprises edetic acid or a salt thereof.

A method for changing a condition of an eyelid of a hairless animal, a model animal for evaluating a therapeutic or prophylactic effect against an eyelid disease obtained by the method, a method for producing the model animal, a method of screening using the model animal and a substance having a therapeutic or prophylactic effect against an eyelid disease selected by the method of screening, and a therapeutic or prophylactic agent against an eyelid disease containing the substance as an active ingredient.

Provided is a pharmaceutical preparation for treatment or prevention of glaucoma or ocular hypertension, comprising 0.0003 to 0.01% (w/v) of isopropyl (6-{[4-(pyrazol-1-yl)benzyl](pyridin-3-ylsulfonyl)aminomethyl}pyridin-2-ylamino)acetate, or a salt thereof.

The present invention provides an effective preparation method and/or an effective purification method of (R)-11-[2-[2-[(diethylamino)methyl]-1-piperidinyl]acetyl]-5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one or a salt thereof in high yield and high purity which is free of impurities, particularly 11-(2-chloroacetyl)-5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one.

The present invention provides a pharmaceutical preparation comprising an aqueous pharmaceutical composition comprising (R)-11-[2-[2-[(diethylamino)methyl]-1-piperidinyl]acetyl]-5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one or a salt thereof, wherein the aqueous pharmaceutical composition is stored in a package which blocks a light having a wavelength of from 210 to 380 nm, in which the stability of (R)-11-[2-[2-[(diethylamino)methyl]-1-piperidinyl]acetyl]-5,11-dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one or the salt thereof in the aqueous pharmaceutical composition is improved.

Provided is a pharmaceutical preparation for treatment or prevention of glaucoma or ocular hypertension, comprising 0.0003 to 0.01% (w/v) of isopropyl (6-{[4-(pyrazol-1-yl)benzyl] (pyridin-3-ylsulfonyl)aminomethyl}pyridin-2-ylamino)acetate, or a salt thereof.

The present invention aims to find a pharmaceutical preparation which treats or prevents glaucoma or ocular hypertension and is effective for patients with inadequate efficacies of glaucoma or ocular hypertension therapeutic agents. It has been found that omidenepag, an ester thereof, or a salt thereof has an excellent intraocular pressure lowering efficacy on patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents. Therefore, the omidenepag, the ester thereof, or the salt thereof of the present invention is useful as a pharmaceutical preparation which can treat or prevent glaucoma or ocular hypertension even in patients with inadequate efficacies of other glaucoma or ocular hypertension therapeutic agents.

The present disclosure provides an agent for treating or preventing eye diseases such as presbyopia, comprising, as an active ingredient, 4-phenylbutyric acid or an ester thereof, or a pharmaceutically acceptable salt thereof.
