Description
本発明は,一般的には高分子多糖類の水溶液における粘性低下の抑制に関し,特に,ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤における粘度低下の抑制に関する。 The present invention generally relates to suppression of viscosity reduction in an aqueous solution of a high molecular polysaccharide, and particularly relates to suppression of viscosity reduction in an aqueous liquid preparation containing hyaluronic acid or a pharmaceutically acceptable salt thereof.
ヒアルロン酸は,D−N−アセチルグルコサミン分子とD−グルクロン酸分子が交互に多数結合して構成された,直鎖状の高分子多糖である。ヒアルロン酸又はその塩の水溶液は,高い粘性を有しており,保水力もあること等から,種々の用途の水性液剤に広く用いられている。しかしながら,ヒアルロン酸又はその塩を含有する水溶液は,緩衝液で中性付近のpHに調整された場合,長期間の保存中にヒアルロン酸が分解される等の理由で粘度が低下することが知られており,粘度を長期間維持できないという問題があった。 Hyaluronic acid is a linear high-molecular polysaccharide composed of many DN-acetylglucosamine molecules and D-glucuronic acid molecules bonded alternately. An aqueous solution of hyaluronic acid or a salt thereof is widely used as an aqueous liquid agent for various applications because it has high viscosity and has water retention ability. However, it is known that an aqueous solution containing hyaluronic acid or a salt thereof, when adjusted to a pH close to neutral with a buffer solution, decreases in viscosity due to degradation of hyaluronic acid during long-term storage. There is a problem that the viscosity cannot be maintained for a long time.
ヒアルロン酸含有水性液剤の粘度の経時的低下を抑制する方法としては,そのような水性液剤に,粘度安定化剤としてポリオール,ポリカルボン酸,ポリカルボン酸塩及び糖質よりなる群から選ばれる少なくとも1種を配合すること(特許文献1),ヒアルロン酸の分解を抑制するために脂溶性ビタミン類を配合すること(特許文献2),及びグルコン酸又はその金属塩を含有させること(特許文献3)が,それぞれ知られている。しかしながら,用途や適用方法等によっては,ヒアルロン酸含有水性液剤の組成に様々な制約がかかり得るため,これら従来知られている方法のみでは,粘度の経時的低下の抑制という必要性には十分対応し切れない。 As a method for suppressing the time-dependent decrease in the viscosity of the hyaluronic acid-containing aqueous solution, at least selected from the group consisting of polyols, polycarboxylic acids, polycarboxylates and sugars as viscosity stabilizers in such aqueous solutions. Blending one kind (Patent Document 1), blending fat-soluble vitamins to suppress the degradation of hyaluronic acid (Patent Document 2), and containing gluconic acid or a metal salt thereof (Patent Document 3) ) Are known. However, the composition of the hyaluronic acid-containing aqueous liquid preparation may be subject to various restrictions depending on the application and application method. Therefore, these conventionally known methods are sufficient to meet the need for suppressing the decrease in viscosity over time. I can't do it.
他方,プラノプロフェン含有の液状外用剤により眼部や鼻腔内等の患部に出現する痛みと痒みが,コンドロイチン硫酸ナトリウムやヒアルロン酸等のムコ多糖類をそのような液状外用剤に配合することで軽減できること(特許文献4),及びプラノプロフェン等種々の薬物について,これを含有する水性液状組成物の長期保存時における異物の析出を防止するために,そのような水性液状組成物にヒアルロン酸ナトリウムを配合すること(特許文献5)が知られているが,それぞれの場合について,組成物の粘度に関する言及はない。 On the other hand, pain and itching appearing in affected areas such as the eye and nasal cavity due to pranoprofen-containing liquid external preparations can be obtained by adding mucopolysaccharides such as sodium chondroitin sulfate and hyaluronic acid to such liquid external preparations. In order to prevent the precipitation of foreign substances during long-term storage of an aqueous liquid composition containing various drugs such as pranoprofen, which can be reduced (Patent Document 4), hyaluronic acid is added to such an aqueous liquid composition. It is known to blend sodium (Patent Document 5), but there is no mention of the viscosity of the composition in each case.
上記の背景において,本発明の目的は,ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤における粘度の経時的低下を抑制するための新たな手段を提供することである。 In the above background, an object of the present invention is to provide a new means for suppressing a decrease in viscosity over time in an aqueous liquid preparation containing hyaluronic acid or a pharmaceutically acceptable salt thereof.

上記構成になる本発明によれば,ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤の経時的な粘度低下を抑制して長期間の保存でも粘度を安定に維持するための,新たな手段を提供することができる。 According to the present invention having the above-described configuration, it is possible to stably maintain the viscosity even during long-term storage by suppressing the decrease in viscosity over time of the aqueous liquid preparation containing hyaluronic acid or a pharmaceutically acceptable salt thereof. , Can provide new means.
なお本発明において,水性液剤の「粘度の低下」の有無及び程度は,水性液剤を60℃で4週間静置保存した場合における,保存開始前の水性液剤の動粘度と比較した保存後の動粘度(20.0℃にて測定)の低下により評価される。 In the present invention, the presence / absence and degree of “decrease in viscosity” of the aqueous liquid is determined by the dynamics after storage compared to the kinematic viscosity of the aqueous liquid before starting storage when the aqueous liquid is stored at 60 ° C. for 4 weeks. It is evaluated by a decrease in viscosity (measured at 20.0 ° C.).
本発明において,ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤の粘度低下の抑制は,当該水性液剤の特定条件での特定期間保存後の粘度保持率に比して,これに所定の抑制成分(プラノプロフェン若しくはその薬剤学的に許容し得る塩又はこれに加えエデト酸若しくはその薬剤学的に許容し得る塩)を更に配合してなる水性液剤の同一条件での同一期間の保存後の粘度保持率の方が高いことにより確認される。ここに,粘度保持率は,次式で規定される値である。
粘度保持率(%)=(保存後の動粘度−1)/(保存前の動粘度−1)×100In the present invention, the suppression of the viscosity decrease of an aqueous liquid preparation containing hyaluronic acid or a pharmaceutically acceptable salt thereof is compared with the viscosity retention rate after storage for a specific period of time in the specific conditions of the aqueous liquid preparation. The same under the same conditions of an aqueous liquid preparation further comprising a predetermined inhibitory component (planoprofen or a pharmaceutically acceptable salt thereof or edetic acid or a pharmaceutically acceptable salt thereof) This is confirmed by the higher viscosity retention after storage of the period. Here, the viscosity retention is a value defined by the following equation.
Viscosity retention (%) = (kinematic viscosity after storage-1) / (kinematic viscosity before storage-1) × 100
本発明において,「ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する」というときは,ヒアルロン酸又はヒアルロン酸の薬剤学的に許容し得る塩の何れか一方のみを含有する場合のみならず,ヒアルロン酸及びその薬剤学的に許容し得る塩の双方を同時に含有する場合を包含する。「プラノプロフェン又はその薬剤学的に許容し得る塩を配合」,及び「エデト酸又はその薬剤学的に許容し得る塩を更に配合」というときも同様である。 In the present invention, the phrase “contains hyaluronic acid or a pharmaceutically acceptable salt thereof” only includes hyaluronic acid or a pharmaceutically acceptable salt of hyaluronic acid. It includes the case of containing both hyaluronic acid and a pharmaceutically acceptable salt thereof simultaneously. The same applies when “planoprofen or a pharmaceutically acceptable salt thereof is added” and “edetic acid or a pharmaceutically acceptable salt thereof is further added”.
本発明により粘度低下を抑制しようとする水性液剤中のヒアルロン酸又はその薬理学的に許容し得る塩の濃度には,明確な上限や下限はないが,好ましくは0.001〜1.0w/v%である。これは,ヒアルロン酸又はその薬剤学的に許容し得る塩の濃度が0.001w/v%より低いときはそれにより得られる粘度がもともと僅かであり,そのような水性液剤においては粘度が重要な技術的意味を持たないこと,及び1.0w/v%より高いときは水性液剤が製造困難な程に高粘度となり,そのような薬剤は実用性に乏しいことによる。水性液剤中のヒアルロン酸又はその薬剤学的に許容し得る塩の濃度は,より好ましくは0.002〜0.5w/v%,更に好ましくは0.005〜0.5w/v%,なおも更に好ましくは0.005〜0.3w/v%,特に好ましくは0.02〜0.3w/v%,取り分け好ましくは0.01〜0.3w/v%である。 The concentration of hyaluronic acid or a pharmacologically acceptable salt thereof in an aqueous solution intended to suppress a decrease in viscosity according to the present invention has no clear upper limit or lower limit, but preferably 0.001 to 1.0 w / v%. This is because when the concentration of hyaluronic acid or a pharmaceutically acceptable salt thereof is lower than 0.001 w / v%, the resulting viscosity is inherently low, and viscosity is important in such aqueous solutions. This is because it has no technical meaning, and when it is higher than 1.0 w / v%, the aqueous solution becomes so viscous that it is difficult to produce, and such a drug is not practical. The concentration of hyaluronic acid or a pharmaceutically acceptable salt thereof in the aqueous liquid is more preferably 0.002 to 0.5 w / v%, still more preferably 0.005 to 0.5 w / v%, still More preferably, it is 0.005-0.3 w / v%, Most preferably, it is 0.02-0.3 w / v%, Especially preferably, it is 0.01-0.3 w / v%.
本発明において,ヒアルロン酸の分子量については特に限定はない。現在,重量平均分子量がおよそ40万〜400万のものが入手可能であり,本発明は,これらのヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤の粘度低下の抑制に使用することができる。 In the present invention, the molecular weight of hyaluronic acid is not particularly limited. Currently, those having a weight average molecular weight of about 400,000 to 4 million are available, and the present invention is used to suppress a decrease in viscosity of an aqueous solution containing these hyaluronic acid or a pharmaceutically acceptable salt thereof. can do.
本発明において,ヒアルロン酸の薬剤学的に許容し得る塩として特に好ましいのはナトリウム塩であるが,これに限定されず,他にも,例えば,カリウム塩,カルシウム塩,マグネシウム塩が,好ましい塩として挙げられる。 In the present invention, sodium salt is particularly preferable as a pharmaceutically acceptable salt of hyaluronic acid, but is not limited thereto, and other examples include potassium salt, calcium salt, and magnesium salt. As mentioned.
なお,本発明において,ヒアルロン酸又はその薬理学的に許容し得る塩について「濃度」又は「重量部」というときは,ヒアルロン酸とその薬剤学的に許容し得る塩の双方を含有する水性液剤については,ヒアルロン酸とその薬剤学的に許容し得る塩との合計での「濃度」又は「重量部」をいう。 In the present invention, the term “concentration” or “part by weight” for hyaluronic acid or a pharmacologically acceptable salt thereof is an aqueous solution containing both hyaluronic acid and a pharmaceutically acceptable salt thereof. Refers to the “concentration” or “part by weight” of hyaluronic acid and its pharmaceutically acceptable salt in total.
プラノプロフェン(化学名:(2RS)-2-(10H-9-Oxa-1-azaanthracen-6-yl)propanoic
acid;(2RS)-2-(10H-9-オキサ-1-アザアントラセン-6-イル)プロパン酸)又はその薬剤学的に許容し得る塩は,安全域の広い非ステロイド抗炎症薬である。プラノプロフェンの薬剤学的に許容される塩の例としては,ナトリウム塩及びカリウム塩が挙げられるが,これらに限定されない。Planoprofen (chemical name: (2RS) -2- (10H-9-Oxa-1-azaanthracen-6-yl) propanoic
(2RS) -2- (10H-9-oxa-1-azaanthracen-6-yl) propanoic acid) or a pharmaceutically acceptable salt thereof is a non-steroidal anti-inflammatory drug with a wide range of safety . Examples of pharmaceutically acceptable salts of pranoprofen include, but are not limited to, sodium and potassium salts.
本発明において,プラノプロフェン及びその薬剤学的に許容し得る塩は,ヒアルロン酸又はその薬剤学的に許容し得る塩を含有する水性液剤における経時的な粘度低下に対する抑制剤として機能する。水性液剤中のプラノプロフェン又はその薬剤学的に許容し得る塩の濃度は適宜設定することができるが,好ましくは0.001〜1.0w/v%である。通常,1.0w/v%より高いと製剤の製造が困難であり,0.001w/v%より低いと十分な粘度安定化効果が認められないためである。水性液剤中のプラノプロフェン又はその薬剤学的に許容し得る塩の濃度は,より好ましくは0.005〜0.5w/v%,更に好ましくは0.05〜0.1w/v%である。また,プラノプロフェン又はその薬剤学的に許容し得る塩のうち,特に好ましいのはプラノプロフェンである。 In the present invention, pranoprofen and a pharmaceutically acceptable salt thereof function as an inhibitor against a decrease in viscosity over time in an aqueous solution containing hyaluronic acid or a pharmaceutically acceptable salt thereof. The concentration of pranoprofen or a pharmaceutically acceptable salt thereof in the aqueous liquid can be appropriately set, but is preferably 0.001 to 1.0 w / v%. Usually, when it is higher than 1.0 w / v%, it is difficult to produce the preparation, and when it is lower than 0.001 w / v%, a sufficient viscosity stabilizing effect is not recognized. The concentration of pranoprofen or a pharmaceutically acceptable salt thereof in the aqueous liquid is more preferably 0.005 to 0.5 w / v%, still more preferably 0.05 to 0.1 w / v% . Of the pranoprofen and pharmaceutically acceptable salts thereof, pranoprofen is particularly preferred.
なお,プラノプロフェン又はその薬理学的に許容し得る塩について「濃度」又は「重量部」というときは,プラノプロフェンとその薬剤学的に許容し得る塩の双方を配合する場合については,プラノプロフェンとその薬剤学的に許容し得る塩との合計での「濃度」又は「重量部」をいう。 The term “concentration” or “part by weight” for pranoprofen or its pharmacologically acceptable salt refers to the case where both pranoprofen and its pharmaceutically acceptable salt are formulated. “Concentration” or “parts by weight” in the sum of pranoprofen and its pharmaceutically acceptable salt.
エデト酸(エチレンジアミン四酢酸ともいう)又はその薬剤学的に許容し得る塩は,プラノプロフェン又はその薬剤学的に許容し得る塩と併用すると,プラノプロフェン単独の場合の粘度低下抑制効果を更に増強することを,本発明者は見出した。エデト酸又はその薬剤学的に許容し得る塩の例としては,ナトリウム塩及びカリウム塩が挙げられるが,これらに限定されない。特に好ましいのは,エデト酸のナトリウム塩である。エデト酸は1〜4個のナトリウムイオンとの塩を形成する。水性液剤のpHを所望のレベルに調整する限り,何れの塩も使用できるが,エデト酸二ナトリウムが,取り扱いの便という点で好ましい。なお,エデト酸又はその薬剤学的に許容し得る塩は,プラノプロフェンと共にヒアルロン酸又はその薬剤学的に許容し得る塩に配合されている状態で,プラノプロフェンが奏する粘度低下抑制効果を更に増強するように作用するものであることから,本発明において,これら各成分をどのような順序で配合して水性液剤とするかは問わない。 When edetic acid (also referred to as ethylenediaminetetraacetic acid) or a pharmaceutically acceptable salt thereof is used in combination with pranoprofen or a pharmaceutically acceptable salt thereof, the effect of suppressing the decrease in viscosity in the case of pranoprofen alone is exhibited. The inventor has found further enhancement. Examples of edetic acid or a pharmaceutically acceptable salt thereof include, but are not limited to, sodium salt and potassium salt. Particularly preferred is the sodium salt of edetic acid. Edetic acid forms a salt with 1-4 sodium ions. Any salt can be used as long as the pH of the aqueous solution is adjusted to a desired level, but disodium edetate is preferred in terms of handling convenience. It should be noted that edetic acid or a pharmaceutically acceptable salt thereof has a viscosity reduction inhibitory effect exhibited by pranoprofen in a state where it is blended with hyaluronic acid or a pharmaceutically acceptable salt thereof together with pranoprofen. In this invention, it does not ask | require what order these ingredients are mix | blended in order to make an aqueous liquid agent.

It is 8.0, More preferably, it is 7.0-8.0.
以下,実施例を挙げて本発明を更に具体的に説明するが,本発明がそれらの実施例により限定されることは意図しない。 EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not intended to be limited by these examples.
なお,以下の各実施例において,プラノプロフェンとしては株式会社エーピーアイ コーポレ―ション製プラノプロフェン(局方)を,エデト酸二ナトリウム水和物としては関東化学株式会社製エデト酸ナトリウム水和物(局方)を,それぞれ使用した。 In the following examples, pranoprofen is pranoprofen (Pharmacopoeia) manufactured by API Corporation, and edetate disodium hydrate is edetate sodium hydrate manufactured by Kanto Chemical Co., Ltd. Each thing (the pharmacopoeia) was used.
表1〜7に示す各処方に従い,ヒアルロン酸ナトリウム(重量平均分子量1,040,000,生化学工業株式会社)含有の水性液剤を調製した。各水性液剤のpHは7.5とした。各水性液剤を,15mL容量のポリエチレンテレフタレート(PET,グレードRT543)製容器に15mLずつ分注して密封し,60℃にて4週間保存した。保存前及び保存後に,各水性液剤の粘度(動粘度)を,日局(第十五改正)一般試験法の「粘度測定法<2.53>,第1法 毛細管粘度計法」に従い,ウベローデ粘度計を用いて20.0℃にて測定し,「粘度保持率(%)」を,次の式により算出した。
粘度保持率(%)=(保存後の動粘度−1)/(保存前の動粘度−1)×100According to each formulation shown in Tables 1-7, an aqueous liquid preparation containing sodium hyaluronate (weight average molecular weight 1,040,000, Seikagaku Corporation) was prepared. The pH of each aqueous solution was 7.5. Each aqueous solution was dispensed and sealed in a 15 mL container made of polyethylene terephthalate (PET, grade RT543), and stored at 60 ° C. for 4 weeks. Before and after storage, the viscosity (kinematic viscosity) of each aqueous solution was determined according to the “Viscosity Measurement Method <2.53>, Method 1 Capillary Viscometer Method” of the General Test Method of Japan (Fifteenth Revision). It measured at 20.0 degreeC using the viscometer, and "viscosity retention (%)" was computed by the following formula.
Viscosity retention (%) = (kinematic viscosity after storage-1) / (kinematic viscosity before storage-1) × 100
1.プラノプロフェンによる粘度低下抑制効果
表1に見られるように,処方3のプラノプロフェン不含のヒアルロン酸ナトリウム含有水性液剤に較べ,これにプラノプロフェンをそれぞれ0.05及び0.1w/v%配合したものに相当する処方1及び2の水性液剤では,経時的な粘度低下が顕著に抑制された。1. Viscosity reduction inhibitory effect by pranoprofen As seen in Table 1, compared with pranoprofen-free aqueous solution containing sodium hyaluronate in Formula 3, pranoprofen was added to pranoprofen at 0.05 and 0.1 w / v, respectively. In the aqueous liquid preparations of Formulations 1 and 2, which correspond to those formulated with%, the decrease in viscosity over time was remarkably suppressed.
2.プラノプロフェンとエデト酸のナトリウム塩による粘度低下抑制効果
下の表2に見られるとおり,処方1及び2に更にエデト酸のナトリウム塩を配合したものに相当する処方4及び5の水性液剤を調製し,60℃にて4週間保存して,粘度保持率を比較した。その結果,エデト酸のナトリウム塩の併用により粘度低下の抑制が一層顕著となることが判明した。2. Viscosity reduction inhibitory effect of pranoprofen and edetic acid sodium salt As shown in Table 2 below, prepared aqueous solutions of formulations 4 and 5 corresponding to formulations 1 and 2 further blended with sodium salt of edetic acid Then, it was stored at 60 ° C. for 4 weeks, and the viscosity retention was compared. As a result, it was found that the combined use of sodium edetic acid made the suppression of viscosity decrease even more remarkable.
3.エデト酸のナトリウム塩自体の粘度低下抑制効果の有無の検討
ヒアルロン酸ナトリウム含有水性液剤の粘度低下に対するエデト酸のナトリウム塩自体の影響を調べるため,次の表3に処方3Eで示す水性液剤(プラノプロフェン不含の上記処方3にエデト酸二ナトリウム水和物0.01w/v%を加えたものに相当する)を調製し,上記と同様に60℃にて4週間保存した後,粘度保持率を測定し,その結果を処方3につき上記で既に得られている結果と比較した。3. Examination of whether or not the sodium salt of edetic acid itself has the effect of suppressing the decrease in viscosity In order to investigate the influence of sodium salt of edetic acid itself on the decrease in viscosity of the sodium hyaluronate-containing aqueous solution, Corresponding to the above formulation 3 containing edetate disodium hydrate 0.01w / v%), and stored for 4 weeks at 60 ° C. The rate was measured and the results were compared with the results already obtained for Formula 3 above.
表3に見られるように,プラノプロフェン不含の処方3に比べ,これにエデト酸二ナトリウム水和物0.01w/v%を添加したものに相当する処方3Eでは,粘度保持率が低下しており,エデト酸のナトリウム塩自体には,単独でのヒアルロン酸ナトリウム含有水性液剤の粘度低下を抑制する効果は認められなかった。それにも拘わらず,既に表2に示したようにプラノプロフェン0.1w/v%を含有するがエデト酸のナトリウム塩を含有しない前記の処方1及び4に比べ,これらにエデト酸二ナトリウム水和物0.01w/v%を添加したものにそれぞれ相当する処方4及び5が高い粘度保持率を示しているのは,プラノプロフェンとエデト酸のナトリウム塩との組合せにより,何らかの相乗効果が生じたことによるものと考えられる。 As can be seen in Table 3, the viscosity retention is reduced in the formulation 3E corresponding to the addition of 0.01 w / v% edetate disodium hydrate compared to the formulation 3 containing no pranoprofen. Therefore, the sodium salt of edetic acid itself did not show the effect of suppressing the decrease in the viscosity of the aqueous solution containing sodium hyaluronate alone. Nevertheless, as shown in Table 2, edetate disodium water was added to the above formulations 1 and 4 which contained pranoprofen 0.1 w / v% but not sodium edetate. Formulas 4 and 5 corresponding to those with the addition of 0.01% w / v of Japanese show a high viscosity retention because the combination of pranoprofen and sodium salt of edetic acid has some synergistic effect. This is probably due to the fact that it occurred.
4.種々のヒアルロン酸ナトリウム濃度における粘度低下抑制効果
下の表4〜6に示す処方に従って,ヒアルロン酸ナトリウムの濃度を変化させた水性液剤に対し,これにプラノプロフェンを配合した水性液剤,更に,プラノプロフェン及びエデト酸二ナトリウム水和物を配合した水性液剤をそれぞれ調製し,60℃にて4週間保存して,粘度保持率を比較した。その結果,表4〜6に見られるように,何れのヒアルロン酸ナトリウム濃度についても,プラノプロフェンによる粘度低下の顕著な抑制効果,及びエデト酸のナトリウム塩の併用による更に顕著な抑制効果が,共に確認された。4). Viscosity reduction inhibitory effect at various sodium hyaluronate concentrations According to the formulations shown in Tables 4 to 6 below, an aqueous solution in which the concentration of sodium hyaluronate was changed, an aqueous solution containing pranoprofen, and a plano Aqueous solutions containing prophene and disodium edetate hydrate were prepared, stored at 60 ° C. for 4 weeks, and the viscosity retention rates were compared. As a result, as shown in Tables 4 to 6, for any sodium hyaluronate concentration, there is a remarkable inhibitory effect on the decrease in viscosity by pranoprofen, and a more remarkable inhibitory effect by the combined use of sodium salt of edetic acid. Both were confirmed.
5.粘度抑制効果に対する緩衝剤の変更の影響の有無の検討
処方1及び4における緩衝剤をリン酸緩衝液に変更したものである表7の処方15及び16と,処方16からプラノプロフェンを除いたものである処方17に従って,水性液剤をそれぞれ調製し,60℃にて4週間保存して,粘度保持率を調べた。その結果,処方15及び16の水性液剤の粘度保持率は,処方1及び4の水性液剤の粘度保持率と実質的に同等であり,ホウ酸緩衝剤からリン酸緩衝剤に変更したことは,プラノプロフェン単独,プラノプロフェンとエデト酸のナトリウム塩との併用,及びエデト酸のナトリウム塩単独の何れが奏する粘度低下抑制効果にも,実質的影響を与えなかった。
また,エデト酸のナトリウム塩は含有するがプラノプロフェンを含有しないものである処方17の水性液剤の粘度保持率は,25%と小さく,粘度低下抑制成分を含まない処方3(ホウ酸緩衝剤。ヒアルロン酸ナトリウム濃度は同一)の水性液剤での値29%との比較からは,エデト酸のナトリウム塩単独での粘度低下抑制効果は認められなかった。5). Examination of the effect of changing the buffering agent on the viscosity suppression effect Formulations 15 and 16 in Table 7 in which the buffering agent in Formulations 1 and 4 was changed to phosphate buffer, and pranoprofen were excluded from Formulation 16 Aqueous liquid preparations were respectively prepared according to the formulation 17 and stored at 60 ° C. for 4 weeks, and the viscosity retention rate was examined. As a result, the viscosity retention of the aqueous solutions of formulations 15 and 16 was substantially the same as the viscosity retention of the aqueous solutions of formulations 1 and 4, and the change from borate buffer to phosphate buffer was Neither the effect of pranoprofen alone, the combination of pranoprofen and sodium edetate, or the sodium salt of edetic acid alone had any substantial effect on the viscosity-inhibiting effect.
In addition, the viscosity retention of the aqueous solution of Formulation 17 that contains sodium salt of edetic acid but does not contain pranoprofen is as low as 25%, and Formula 3 (Boric Acid Buffer In comparison with the value of 29% in the case of the aqueous solution of the same sodium hyaluronate concentration), the sodium salt of edetic acid alone did not show the effect of suppressing the viscosity decrease.
6.低濃度ヒアルロン酸水性液剤におけるプラノプロフェンによる粘度低下抑制効果の確認
次の表8に示す各処方に従い,上記処方例より低濃度領域でヒアルロン酸ナトリウム(重量平均分子量3,220,000,キューピー株式会社製ヒアルロンサンHA−QSE)を含有する水性液剤を調製した。各水性液剤のpHは7.5とした。上記の各実施例と同様に,各水性液剤を,15mL容量のポリエチレンテレフタレート(PET)製容器に15mLずつ分注して密封し,60℃にて4週間保存した。保存前及び保存後に,各水性液剤の粘度(動粘度)を,上記各実施例と同様にして測定し,粘度保持率を算出し,結果を比較した。6). Confirmation of Viscosity Reduction Inhibition Effect by Planoprofen in Low Concentration Hyaluronic Acid Aqueous Solution According to each formulation shown in the following Table 8, sodium hyaluronate (weight average molecular weight 3,220,000, cupy stock in lower concentration region than the above formulation example) An aqueous solution containing Hyaluronic Sun (HA-QSE) was prepared. The pH of each aqueous solution was 7.5. In the same manner as in the above Examples, each aqueous solution was dispensed and sealed in a 15 mL polyethylene terephthalate (PET) container, and stored at 60 ° C. for 4 weeks. Before and after storage, the viscosity (kinematic viscosity) of each aqueous liquid was measured in the same manner as in each of the above Examples, the viscosity retention was calculated, and the results were compared.
表8は,ヒアルロン酸ナトリウムを0.001,0.002,又は0.005w/v%の各濃度で含有する水性液剤において,プラノプロフェンの配合の有無での粘度保持率の測定結果を示しており,これら何れのヒアルロン酸ナトリウム濃度の群でも,プラノプロフェン不含のものに比べプラノプロフェンを配合した水性液剤の粘度保持率が,顕著に高い。 Table 8 shows the measurement results of the viscosity retention with and without pranoprofen in aqueous liquids containing sodium hyaluronate at concentrations of 0.001, 0.002, or 0.005 w / v%. In any of these groups of sodium hyaluronate concentrations, the viscosity retention of the aqueous liquid formulation containing pranoprofen is remarkably higher than that without pranoprofen.
以上のとおり,ヒアルロン酸ナトリウム含有の水性液剤の経時的な粘度低下は,プラノプロフェンの配合によって,ヒアルロン酸の分子量の大小に関わりなく顕著に抑制されることが判明した。またこれに更にエデト酸のナトリウム塩を配合することにより,抑制が一層顕著になることも判明した。また,種々のヒアルロン酸ナトリウム濃度において,プラノプロフェンの配合,及びプラノプロフェンとエデト酸のナトリウム塩との併用により,水性液剤の粘度低下に対する優れた抑制効果の得られること,及び緩衝剤の種類による影響を受けないことが,それぞれ確認された。 As described above, it was found that the decrease in viscosity over time of an aqueous solution containing sodium hyaluronate was significantly suppressed by the incorporation of pranoprofen regardless of the molecular weight of hyaluronic acid. In addition, it was also found that the suppression becomes even more remarkable by adding edetic acid sodium salt. In addition, at various sodium hyaluronate concentrations, the combination of pranoprofen and the combined use of pranoprofen and sodium edetate can provide an excellent inhibitory effect on the viscosity reduction of aqueous solutions, and It was confirmed that they were not affected by type.
