Description
本發明係有關含有高濃度維生素A之眼科用組成物。The present invention relates to an ophthalmic composition containing a high concentration of vitamin A.
維生素A係作為預防、治療角膜、結膜、皮膚黏膜之角化症等之有效成份倍受矚目。另外,脂溶性維生素之維生素A對於空氣、光、熱、酸、金屬離子等極為敏感,特別是於水溶液中極不穩定,因此極不易穩定配合於點眼劑等之眼科用組成物。Vitamin A is attracting attention as an effective ingredient for preventing and treating cornea, conjunctiva, and keratosis of the skin and mucous membranes. Further, the vitamin A of the fat-soluble vitamin is extremely sensitive to air, light, heat, acid, metal ions, etc., and is extremely unstable in an aqueous solution, and therefore it is extremely difficult to stably mix with an ophthalmic composition such as an eye drop.
作為將此不穩定之維生素A進行穩定化技術者,先行技術中,被揭示有:以聚乙烯硬化萞麻子油等之非離子界面活性劑(如:特開平5-331056號公報:專利文獻1)、疏水性抗氧化劑之維生素E類進行穩定化之方法(如:特開平6-247853號公報:專利文獻2)、及由容器、包裝面之穩定化技術(如:特開平6-40907號公報:專利文獻3、特開2003-113078號公報:專利文獻4)、藉由高能量乳化所製造之穩定化技術(如:特開2002-332225號公報:專利文獻5)。惟,先行技術中,於高濃度系(50,000單位以上)時,並無法充分滿足醫藥品水準所需要之穩定性。因此,被期待一種配合高濃度維生素A之眼科用組成物中,進一步提昇維生素A安定化之技術。As a technique for stabilizing the unstable vitamin A, a non-ionic surfactant such as a hardened castor oil such as polyethylene is disclosed in the prior art (for example, Japanese Patent Publication No. Hei 5-331056: Patent Document 1 A method for stabilizing a vitamin E type of a hydrophobic antioxidant (for example, JP-A-6-247853: Patent Document 2), and a stabilization technique by a container or a packaging surface (e.g., JP-A-6-40907) Japanese Patent Laid-Open Publication No. JP-A No. 2002-332225 (Patent Document 5). However, in the advanced technology, when the concentration is high (50,000 units or more), the stability required for the pharmaceutical level cannot be sufficiently satisfied. Therefore, it is expected that an ophthalmic composition containing a high concentration of vitamin A can further enhance the technology of vitamin A stabilization.

(B)成份可單獨使用1種或適當組合2種以上使用之,其含量,對於眼科用組成物總量而言,為0.4W/V%以上者宜,較佳者為0.4~5W/V%,更佳者為0.5~3W/V%,特別理想者為0.6~2W/V%,最為理想者1~2W/V%。當未達0.4W/V%時,則維生素A的可溶化變得不易,由維生素A之保存穩定性之面視之,為5W/V%以下者宜。(B) The component may be used singly or in combination of two or more kinds, and the content thereof is preferably 0.4 W/V% or more for the total amount of the ophthalmic composition, preferably 0.4 to 5 W/V. %, preferably 0.5~3W/V%, especially ideally 0.6~2W/V%, ideally 1~2W/V%. When it is less than 0.4 W/V%, the solubilization of vitamin A becomes difficult, and it is preferable that it is 5 W/V% or less from the viewpoint of the storage stability of vitamin A.
由維生素A保存安定化之觀點視之,以[(A)維生素A單位/100mL]/[(B)聚氧化乙烯聚氧化丙烯二醇g/100mL]所代表之(A)成份與(B)成份之比率為10,000~150,000者宜,較佳者為15,000~100,000,更佳者為25,000~50,000。From the viewpoint of preservation and stability of vitamin A, (A) and (B) represented by [(A) vitamin A unit / 100 mL] / [(B) polyoxyethylene polyoxypropylene diol g / 100 mL] The ratio of ingredients is 10,000 to 150,000, preferably 15,000 to 100,000, and more preferably 25,000 to 50,000.
本發明之眼科用組成物中,由提昇維生素A之保存安定性之面視之,以添加trometamol者宜。於trometamol中可提昇維生素A之保存安定性之效果係本發明的新發現。此機序並未明朗,而可由以下被推測。聚氧化乙烯聚氧化丙烯二醇係具有聚氧化乙烯(EO)鏈與聚氧化丙烯(PO)鏈之非離子性界面活性劑。使EO鏈為外側、PO鏈為內側,包住維生素A,形成膠粒。與trometamol共存後,存在於trometamol中之-NH2 基直接與EO鏈之醚鍵鍵結,故使膠粒之構造極為強固。trometamol更藉由與膠粒外側之EO鏈鍵結,強固膠粒之構造後,降低自由度,其結果,降低膠粒內部之PO鏈的分子運動性。由上述,可認定trometamol可賦予維生素A與聚氧化乙烯聚氧化丙烯二醇所形成之膠粒的安定化,其結果亦賦予維生素A之保存安定性。In the ophthalmic composition of the present invention, it is preferred to add trometamol by enhancing the preservation stability of vitamin A. The effect of enhancing the preservation stability of vitamin A in trometamol is a novel discovery of the present invention. This sequence is not clear and can be inferred from the following. The polyoxyethylene polyoxypropylene diol is a nonionic surfactant having a polyoxyethylene (EO) chain and a polyoxypropylene (PO) chain. The EO chain is the outer side and the PO chain is the inner side, and the vitamin A is encapsulated to form a colloidal particle. After coexistence with trometamol, the -NH 2 group present in trometamol is directly bonded to the ether bond of the EO chain, so that the structure of the colloidal particles is extremely strong. Trometamol further reduces the degree of freedom by bonding the EO chain to the outer side of the colloidal particles, thereby reducing the molecular mobility of the PO chain inside the colloidal particles. From the above, it can be confirmed that trometamol can impart stability to the colloidal particles formed by vitamin A and polyoxyethylene polyoxypropylene diol, and as a result, the preservation stability of vitamin A is also imparted.
(C)trometamol之含量對於眼科用組成物總量而言,為0.01~5W/V%者宜,較佳者為0.05~5W/V%,更佳者為0.1~3W/V%,特別理想者為0.5~2W/V%。當未達0.01W/V%時,則恐使維生素A之保存安定化效果不足,反之,超出5W/V%則恐對於眼睛產生刺激感。又,由維生素A保存安定化之觀點視之,(B):(C)所代表之(B)成份與(C)成份之質量比為1:30~30;1者宜,較佳者為1:20~20:1,更佳者為1:10~10:1,最佳者為1:10~3:1。(C) The content of trometamol is preferably 0.01 to 5 W/V% for the total amount of the ophthalmic composition, preferably 0.05 to 5 W/V%, and more preferably 0.1 to 3 W/V%, which is particularly desirable. The value is 0.5~2W/V%. When it is less than 0.01 W/V%, it is feared that the preservation effect of vitamin A is insufficient, and if it exceeds 5 W/V%, it may cause irritation to the eyes. Moreover, from the viewpoint of preservation and stability of vitamin A, (B): (C) represents a mass ratio of (B) component to (C) component of 1:30 to 30; one is preferred, preferably 1:20~20:1, the better is 1:10~10:1, and the best is 1:10~3:1.

Generally, vitamin A is solubilized from polyoxyethylene polyoxypropylene diol in sterilized purified water, followed by adding trometamol and each component. It can be obtained after adjusting the pH. Thereafter, aseptic filling is carried out in a suitable container such as a container made of polyethylene terephthalate or the like.
藉由本發明,即使配合50,000單位/100mL以上之維生素A,仍可經由配合聚氧化乙烯聚氧化丙烯二醇、trometamol,使維生素A安定化。According to the present invention, even if 50,000 units/100 mL or more of vitamin A is blended, vitamin A can be stabilized by blending polyoxyethylene polyoxypropylene diol or trometamol.

In addition, dry eye syndrome is a state in which the keratoconjunctiva on the surface of the eyeball is hindered by the abnormality of the quality or amount of the tear fluid. The tear system is composed of three layers of oil layer, water layer and mucin layer. The quality and quantity of the three-layer structure are damaged, resulting in unstable tears and obstacles in the cornea, causing dry eye syndrome. In the treatment of dry eye, the focus is on restoring the three-layer structure of the oil layer, the water layer and the mucin layer of the tear, and treating the corneal disorder. Further, since the contact lens user is likely to cause dry eye, the ophthalmic composition of the present invention is suitable for eye contact for contact lenses, eye wash after taking out contact lenses, contact lens loading solution, contact lens take-out solution, and the like. When applied to a dry eye treatment, it can be further exerted by eye-dropping once 30 to 60 μL and 3 to 6 times a day.
