Definitions
- the present invention relates to an aqueous ophthalmic composition that improves the intraocular transfer of a drug when a composition containing a drug and a sugar alcohol is administered to the eye.
- ⁇ -blocker eye drops represented by timolol maleate, carteolol hydrochloride and nipradilol are currently widely used as therapeutic agents for glaucoma.
- these drugs are generally highly water-soluble, so the highly hydrophobic corneal epithelium acts as a barrier when the drug enters the eye, and a high dose of ⁇ -blocking is necessary to obtain a sufficient amount of the drug to enter the eye. Instillation of drug-containing eye drops or frequent eye drops is required.
- drugs that are not absorbed into the eye are absorbed throughout the body, so that it is considered that the frequency of serious cardiotoxicity and respiratory toxicity, which are side effects of ⁇ -blockers, increases.
- a high-dose ⁇ -blocker-containing eye drop It is desirable to improve the intraocular transfer of the drug and to increase the intraocular retention rather than the frequent administration or administration of normal doses.
- the pH of the composition is increased by being heated by heat such as body temperature when mixed, or by mixing with tears that are blocking the ocular surface.
- Patent Document 1 It has been possible to instill once a day by utilizing the stagnation property generated by utilizing the sol-gel transition by the gel technology utilizing the change of heat or pH (Patent Document 1, Patent Document 2).
- Patent Document 2 With gelled eye drops, there is a problem in the usage such as fogging or stickiness after administration lasting for several minutes, or requiring attention in patients receiving multiple eye drops. It was. From this point of view, various studies have been made to increase the corneal permeability of ⁇ -blockers. As an example, there is a method of increasing the drug permeability by blending C 3 -C 7 fatty acids (such as sorbic acid) with ⁇ -blocker-containing eye drops (Patent Document 3).
- Patent Document 4 When a ⁇ -blocker is added to an aqueous solution containing alginic acid and a composition having a pH of 6 to 8 is instilled, an effect of extending the action time can be seen after administration (Patent Document 4). ). These exemplified methods have already been applied to timolol maleate eye drops and carteolol hydrochloride eye drops. As a result, it was clarified that by using these methods, the same effect can be obtained by instilling once a day with a reduced number of administrations, whereas usual aqueous eye drops are instilled twice a day. Yes.
- mannitol which is a typical sugar alcohol having a use of an isotonic agent for the purpose of adjusting osmotic pressure
- boric acid or borate is also widely used as a buffering agent or a preservative exhibiting some antibacterial action.
- nothing is known about the effects other than increasing the antibacterial action by boric acid and sugar alcohol.
- the corneal permeability of the ⁇ -blocker As described above, by increasing the corneal permeability of the ⁇ -blocker, it becomes possible to reduce the dose of the drug, such as the number of eye drops, and to reduce systemic side effects.
- the QOL can be improved by reducing the number of administrations, and the therapeutic effect can be prevented from being lowered by forgetting to apply. Therefore, improving the corneal permeability of the drug is very useful.
- the problem to be solved by the present invention is to provide an aqueous ophthalmic composition that improves the corneal permeability of drugs used in the ophthalmic field such as ⁇ -blockers.
- the inventors of the present invention conducted intensive research on eye drops having an effect of improving corneal permeability, particularly for ⁇ -blockers among the therapeutic agents for glaucoma. As a result, it is more versatile as an osmotic pressure adjusting agent for eye drops, stable as a compound, and high in safety, so that sugar alcohols such as mannitol that can be used at high concentrations are added to ⁇ -blocker eye drops. And found that the above problems can be solved. That is, the present invention provides an aqueous ophthalmic composition containing (A) a ⁇ -blocker and (B) a sugar alcohol. In addition to the above, it has also been found that the addition of boric acid enhances the corneal permeability of the ⁇ -blocker.
- the present invention also provides an ophthalmic aqueous composition
- an ophthalmic aqueous composition comprising (A) a ⁇ -blocker, timolol or a pharmaceutically acceptable salt, (B) a sugar alcohol, mannitol and (C) boric acid, gellan gum,
- the ophthalmic aqueous composition does not contain xanthan gum, methylcellulose, or hydroxypropylmethylcellulose.
- the present invention also provides a ⁇ -blocker corneal permeability improver containing a sugar alcohol.
- the present invention also provides the use of a sugar alcohol as a corneal permeability improver for producing an aqueous ophthalmic composition containing a ⁇ -blocker.
- the aqueous ophthalmic composition of the present invention has the effect of improving the corneal permeability of drugs used in the ophthalmic field such as ⁇ -blockers. As a result, it is possible to reduce the dose of the drug, such as reducing the number of instillations. Therefore, for example, reduction of systemic side effects such as cardiotoxicity and respiratory toxicity which are concerned when a ⁇ -blocker is instilled can be expected.
- the QOL can be improved by reducing the number of administrations, and the therapeutic effect can be prevented from being lowered by forgetting to apply.

Abstract
Description
β遮断薬においては、以前より高分子を添加した組成物において、投与した際に体温などの熱によって薬液が加温されること、もしくは眼表面をバリアーしている涙液と混ざることによってpHが変化すること、つまり、熱やpH変化を利用したゲル技術によって、ゾルゲル転移を利用して生じる滞留性を活用し、1日1回点眼を可能としてきた(特許文献1、特許文献2)。しかし、ゲル化点眼液においては、投与後の霧視又はべたつきが数分間持続することや、複数の点眼液を投与している患者において、注意が必要となることなどの使用方法で問題が生じていた。
かかる観点から、β遮断薬の角膜透過性を高めるために種々検討がなされている。その例示としてβ遮断薬含有点眼剤にC3~C7脂肪酸(ソルビン酸など)を配合し薬物の透過性を上げる方法がある(特許文献3)。また、アルギン酸を含有する水溶液にβ遮断薬を加え、そしてそのpHを6~8にした組成物を点眼した場合に、投与後に作用時間の延長効果が見られることなどが挙げられる(特許文献4)。
これら例示した方法は、チモロールマレイン酸塩点眼剤やカルテオロール塩酸塩点眼剤で既に適応されている。その結果、これらの方法を用いることで、通常の水溶液点眼剤が1日2回点眼であるのに対し、投与回数を減らした1日1回点眼で同等の効果が得られることを明らかにしている。
一方で、眼科用剤において、投与後の影響を考慮するために、浸透圧を調節する目的として等張化剤の用途を持つ糖アルコールとして代表的なマンニトールは一般的によく用いられる。別に、緩衝剤やある程度の抗菌作用を示す防腐剤として、ホウ酸あるいはホウ酸塩についても汎用されている。また、眼科用剤において、ホウ酸と糖アルコールを含むポリオールからなるホウ酸-ポリオール複合体によって、ホウ酸単独よりもA.nigerなどの微生物に対する抗菌作用が増強されることはすでに知られており、医薬品における水性組成物の保存効力として活用されている(特許文献5)。しかし、ホウ酸と糖アルコールによって、抗菌作用を増大する以外の効果については、全く知られていない。
すなわち、本発明により、(A)β遮断薬及び(B)糖アルコールを含有する点眼用水性組成物を提供する。
また、前述に加えてホウ酸を配合することで、β遮断薬の角膜透過性を増強することも見出した。
本発明はまた、(A)β遮断薬として、チモロールもしくは薬学的に許容される塩、(B)糖アルコールとして、マンニトール及び(C)ホウ酸を含む点眼用水性組成物であって、ジェランガム、キサンタンガム、メチルセルロース、又はヒドロキシプロピルメチルセルロースを含まない前記点眼用水性組成物を提供する。
本発明はまた、糖アルコールを含有する、β遮断薬の角膜透過性向上剤を提供する。
本発明はまた、β遮断薬を含有する点眼用水性組成物を製造するための、糖アルコールの角膜透過性向上剤としての使用を提供する。
β遮断薬の使用濃度は、眼圧下降効果が得られれば特に制限はないが、通常はフリー体として、0.01~10w/v%、好ましくは0.05~5w/v%であり、より好ましくは0.1~3w/v%である。
前述の中でも、ラタノプロスト、トラボプロストが好ましく、ラタノプロストがさらに好ましい。
これらの薬物の配合量は、その効果が得られれば特に制限はないが、通常0.0001~10w/v%、好ましくは0.0005 ~ 5w/v%であり、より好ましくは0.001~ 5w/v%である。
これらの薬物のこれらの薬物の配合量は、その効果が得られれば特に制限はないが、通常0.001~10w/v%である。
等張化剤としては、プロピレングリコール、グリセリン、塩化ナトリウム、塩化カリウムなどが挙げられる。可溶化剤としては、ポリソルベート80、ポリオキシエチレン硬化ヒマシ油などが挙げられる。
保存剤としては、塩化ベンザルコニウム、塩化ベンゼトニウム及びグルコン酸クロルヘキシジンなどの逆性石鹸類、パラヒドロキシ安息香酸メチル、パラヒドロキシ安息香酸プロピル、パラヒドロキシ安息香酸ブチル等のパラベン類、クロロブタノール、フェニルエチルアルコール及びベンジルアルコールなどのアルコール類、デヒドロ酢酸ナトリウムが例示できる。
安定化剤としては、エチレンジアミン四酢酸及びそれらの薬学的に許容される塩、トコフェロール及びその誘導体、亜硫酸ナトリウムなどが挙げられる。
本発明の組成物にゾルゲル転移を起すまでではないが、ポリマーを添加した場合において、粘性を上げた組成物を調製しても、本発明について相乗効果を示すものではない。ポリマーを添加せずとも、本発明の効果を得ることが可能である。
増粘剤としては、ヒドロキシエチルセルロース、ポリビニルピロリドン、ポリエチレングリコールなどが挙げられるが、本発明の組成物において、20℃粘度は1~15mPa・sであって、好ましくは1~10mPa・s、さらに好ましくは1~5mPa・s、最も好ましくは1mPa・sである。
増粘剤は0.5w/v%を上限として添加することができるが、本発明の組成物には、増粘剤により粘性を持たせることなく、β遮断薬の角膜透過性向上効果を得ることができるため、増粘剤を全く添加しないことがより好ましい。増粘剤を含まない組成物は、べたつきを生じることのないことから、取り扱いが良好になることからも好ましい。
本発明の組成物は、メチルセルロース、ヒドロキシプロピルメチルセルロース(ヒプロメロース)、ジェランガム、キサンタンガム、カルボキシビニールポリマー、ポリアクリル酸ナトリウム、ヒアルロン酸ナトリウム、ポリビニルアルコール、アルギン酸などの増粘剤を含まない。
