Description
本発明は、エアゾール剤組成物に関し、さらに詳しくは、リドカイン又はプロカインを含有し、良好な噴射性を保持しつつ冷却効果の高いシャーベット状泡沫を形成するエアゾール剤組成物に関する。 The present invention relates to an aerosol composition, and more particularly to an aerosol composition containing lidocaine or procaine and forming a sherbet-like foam having a high cooling effect while maintaining good jetting properties.
リドカイン又はプロカインは、局所麻酔薬(local anesthetic)であり、抹消神経において直接的かつ可逆的に神経伝達を遮断してその支配領域の痛覚・運動・自律神経機能を停止させる薬剤である(非特許文献1参照)。皮膚の神経を麻痺させて痒みの伝達を抑制する作用があるため、鎮痒剤の有効成分として配合されている(非特許文献2参照)。 Lidocaine or procaine is a local anesthetic, which is a drug that directly and reversibly blocks nerve transmission in peripheral nerves and stops pain, motor, and autonomic nerve functions in its dominant region (non-patented). Reference 1). Since it has the effect | action which suppresses the transmission of itching by paralyzing the nerve of skin, it is mix | blended as an active ingredient of an antipruritic agent (refer nonpatent literature 2).
また、冷却性の強いシャーベット状の泡沫により、鎮痒効果を高めたエアゾール剤も公開されている(特許文献1及び2参照)。 Moreover, the aerosol agent which improved the antipruritic effect with the sherbet-like foam with strong cooling property is also disclosed (refer patent documents 1 and 2).
そこで、リドカイン等の局所麻酔薬を配合し、冷却効果の高いシャーベット状泡沫を形成するエアゾール剤とすれば、極めてすぐれた鎮痒剤を得ることが期待できる。 Therefore, if a local anesthetic such as lidocaine is blended to form an aerosol agent that forms a sherbet-like foam with a high cooling effect, it can be expected to obtain an extremely excellent antipruritic agent.
実際上、局所麻酔薬を配合し、さらに直鎖モノカルボン酸を配合した、噴射性が良好で冷却効果の高いシャーベット状泡沫を形成するエアゾール剤についての報告はない。 In fact, there is no report on an aerosol agent containing a local anesthetic and further containing a linear monocarboxylic acid that forms a sherbet-like foam with good jetting properties and a high cooling effect.
本発明者らは、局所麻酔薬(リドカイン又はプロカイン)を配合し、噴射時にシャーベット状の泡沫を形成するエアゾール剤の開発を行ってきた。そして、エアゾール剤用原液及び噴射剤を耐圧容器に充填し、経時的な変化を調べたところ、沈殿物が生じ、噴射孔の目詰まり等噴射性状の悪化を招来するに至った。通常のエアゾール剤と異なり、シャーベット状の泡沫を形成するエアゾール剤においては、特に噴射性状を良好に保持することが重要であり、それゆえ、目詰まりの要因となる沈殿物の生成を抑制することは重要な課題である。 The inventors of the present invention have been developing an aerosol agent containing a local anesthetic (lidocaine or procaine) and forming a sherbet-like foam upon injection. And when the pressure | voltage resistant container was filled with the stock solution for aerosol agents and a propellant, and the change with time was investigated, the deposit produced, and it came to cause deterioration of injection properties, such as clogging of an injection hole. Unlike ordinary aerosols, it is important to maintain good jetting properties, especially in aerosols that form sherbet-like foam, and therefore suppress the formation of precipitates that cause clogging. Is an important issue.
すなわち、本発明は、リドカイン又はプロカインを含有し、経時的に沈殿物を生じることなく、良好な噴射性状が保持された冷却用シャーベット状泡沫を形成するエアゾール剤組成物を提供することを課題とする。 That is, an object of the present invention is to provide an aerosol composition containing lidocaine or procaine, and forming a cooling sherbet-like foam that maintains good jetting properties without causing precipitation over time. To do.
本発明者らは、かかる課題を解決すべく鋭意検討を重ねた結果、リドカインを含む原液に乳酸又は塩酸を添加し、該原液のpHを5以下としてエアゾール剤を調製することにより、経時的な沈殿物の生成を抑制し、良好な噴射性状を確保しうることを見出した。 As a result of intensive investigations to solve such problems, the present inventors have added lactic acid or hydrochloric acid to a stock solution containing lidocaine, and prepared an aerosol agent with a pH of the stock solution of 5 or less. It was found that the formation of precipitates can be suppressed and good jetting properties can be secured.
かかる知見に基づき完成した本発明の態様は、(a)リドカイン又はプロカイン、(b)非イオン界面活性剤、(c)炭素原子数10〜22の直鎖モノカルボン酸、(d)乳酸又は強酸、及び(e)水及び炭素原子数1〜3の低級アルコールからなる混合溶媒を含有する原液、並びに(f)ジメチルエーテルを含有する噴射剤からなり、該原液のpHが5以下であることを特徴とするエアゾール剤組成物である。 The embodiments of the present invention completed based on such findings include (a) lidocaine or procaine, (b) a nonionic surfactant, (c) a linear monocarboxylic acid having 10 to 22 carbon atoms, (d) lactic acid or a strong acid. And (e) a stock solution containing a mixed solvent consisting of water and a lower alcohol having 1 to 3 carbon atoms, and (f) a propellant containing dimethyl ether, wherein the pH of the stock solution is 5 or less. An aerosol composition.
本発明により、リドカイン又はプロカインを含有し、良好な噴射性を有するエアゾール剤組成物を提供することが可能となった。 According to the present invention, it is possible to provide an aerosol composition containing lidocaine or procaine and having good jetting properties.
リドカイン及びプロカインは局所麻酔薬である。これらは塩の形態で配合してもよい。塩としては、例えば、塩酸塩が挙げられる。
各局所麻酔薬の配合(含有)量は、鎮痒効果の増強という点から、リドカインでは、原液中0.1〜5質量%であり、0.2〜3質量%が好ましい。プロカインでは、原液中0.05〜5質量%であり、0.1〜3質量%が好ましい。これらは単独で配合した場合の配合量であるが、各々の配合量を適宜に調整し、2種を組み合わせて配合してもよい。
Lidocaine and procaine are local anesthetics. You may mix | blend these with the form of a salt. Examples of the salt include hydrochloride.
The amount (inclusive) of each local anesthetic is 0.1 to 5% by mass, preferably 0.2 to 3% by mass in the stock solution for lidocaine from the viewpoint of enhancing the antipruritic effect. In procaine, it is 0.05-5 mass% in a stock solution, and 0.1-3 mass% is preferable. These are blending amounts when blended alone, but the blending amounts may be adjusted as appropriate, and two may be blended in combination.
非イオン界面活性剤は、噴射時にシャーベット状の泡沫を形成するために必要な成分である。例えば、ポリオキシエチレンアルキルエーテル、ポリオキシエチレン硬化ヒマシ油、ソルビタン脂肪酸エステル、グリセリン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ポリエチレングリコール脂肪酸エステル、プロピレングリコール脂肪酸エステル、ポリオキシエチレンソルビット脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、ポリオキシエチレングリセリン脂肪酸エステル、ポリオキシエチレンポリオキシプロピレンアルキルエーテル、ポリオキシエチレンアルキルフェニルエーテル、ポリオキシエチレンヒマシ油が挙げられる。これらのうち、好ましいのは、ポリオキシエチレンセチルエーテル、ポリオキシエチレンステアリルエーテル、ポリオキシエチレンベヘニルエーテル、モノステアリン酸ポリエチレングリコール、モノステアリン酸プロピレングリコール、ポリオキシエチレンポリオキシプロピレンセチルエーテル、ポリオキシエチレンソルビタントリステアレート、ポリオキシエチレンソルビタンモノステアレート、ポリオキシエチレングリセリルモノステアレートであり、特に好ましいのは、ポリオキシエチレンセチルエーテル、ポリオキシエチレンステアリルエーテル、ポリオキシエチレンソルビタントリステアレート及びポリオキシエチレンソルビタンモノステアレートである。これら非イオン界面活性剤は、単独で用いてもよいが、2種以上を組み合わせて用いてもよい。
非イオン界面活性剤の配合(含有)量は、通常、原液中0.1〜15質量%であり、0.5〜10質量%が好ましい。非イオン界面活性剤の配合(含有)量が組成物中0.1質量%未満であると、噴射物がシャーベット状になりにくくなり、持続的な冷感が弱くなるため、好ましくない。一方、15質量%を超えると、非イオン界面活性剤が溶解しにくくなり、製造が困難になるため、好ましくない。
The nonionic surfactant is a component necessary for forming a sherbet-like foam during jetting. For example, polyoxyethylene alkyl ether, polyoxyethylene hydrogenated castor oil, sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, polyethylene glycol fatty acid ester, propylene glycol fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene sorbitan fatty acid Examples include esters, polyoxyethylene glycerin fatty acid esters, polyoxyethylene polyoxypropylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, and polyoxyethylene castor oil. Among these, polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, polyoxyethylene behenyl ether, polyethylene glycol monostearate, propylene glycol monostearate, polyoxyethylene polyoxypropylene cetyl ether, polyoxyethylene Sorbitan tristearate, polyoxyethylene sorbitan monostearate, polyoxyethylene glyceryl monostearate, particularly preferred are polyoxyethylene cetyl ether, polyoxyethylene stearyl ether, polyoxyethylene sorbitan tristearate and polyoxy Ethylene sorbitan monostearate. These nonionic surfactants may be used alone or in combination of two or more.
The blending (content) amount of the nonionic surfactant is usually 0.1 to 15% by mass in the stock solution, and preferably 0.5 to 10% by mass. When the blending (contained) amount of the nonionic surfactant is less than 0.1% by mass in the composition, the sprayed product is less likely to form a sherbet, and the persistent cooling sensation is weakened. On the other hand, if it exceeds 15% by mass, the nonionic surfactant becomes difficult to dissolve and the production becomes difficult, which is not preferable.
炭素原子数10〜22の直鎖モノカルボン酸は、噴射時にシャーベット状の泡沫を形成するために必要な成分である。例えば、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸及びベヘニン酸が挙げられ、中でもステアリン酸が特に好ましい。
直鎖モノカルボン酸の配合(含有)量は、通常、原液中0.1〜14質量%であり、好ましくは0.5〜10質量%、さらに好ましくは1〜5質量%である。直鎖モノカルボン酸の配合(含有)量が原液中0.1質量%未満であると噴射物がシャーベット状になりにくくなり、持続的な冷感が弱くなるため、好ましくない。一方、14質量%を超えると直鎖モノカルボン酸が溶解しにくくなり、製造が困難になるため、好ましくない。
A linear monocarboxylic acid having 10 to 22 carbon atoms is a component necessary for forming a sherbet-like foam during injection. Examples thereof include lauric acid, myristic acid, palmitic acid, stearic acid and behenic acid, and stearic acid is particularly preferable.
The blending (content) amount of the linear monocarboxylic acid is usually 0.1 to 14% by mass in the stock solution, preferably 0.5 to 10% by mass, and more preferably 1 to 5% by mass. When the blending (content) amount of the linear monocarboxylic acid is less than 0.1% by mass in the stock solution, the sprayed product is unlikely to become a sherbet, and the continuous cooling sensation becomes weak. On the other hand, if it exceeds 14% by mass, the straight-chain monocarboxylic acid is difficult to dissolve and the production becomes difficult, which is not preferable.
水及び炭素原子数1〜3の低級アルコールからなる混合溶媒における水と炭素原子数1〜3の低級アルコールの配合比は10:90〜90:10であり、該混合溶媒の原液中における配合(含有)量は40〜99質量%である。
炭素原子数1〜3の低級アルコールは、炭素原子数1〜3の直鎖状又は分岐鎖状のアルコールである。メタノール、エタノール、プロパノール、イソプロパノールが挙げられるが、好ましいのは、エタノール又はイソプロパノールであり、特に好ましいのは、エタノールである。
The mixing ratio of water and the lower alcohol having 1 to 3 carbon atoms in the mixed solvent composed of water and the lower alcohol having 1 to 3 carbon atoms is 10:90 to 90:10, and the mixing ratio of the mixed solvent in the stock solution ( Content) is 40 to 99% by mass.
The lower alcohol having 1 to 3 carbon atoms is a linear or branched alcohol having 1 to 3 carbon atoms. Although methanol, ethanol, propanol, and isopropanol are mentioned, ethanol or isopropanol is preferable, and ethanol is particularly preferable.
本発明においては、原液のpHを5以下に調整するための酸が必須である。酸としては、乳酸又は塩酸等の強酸が挙げられるが、例えば、リドカインの塩酸塩を配合した場合のように、薬物の塩の形態で配合し、結果的に酸が含有される場合も本発明の酸の配合に含まれる。酸として好ましいのは、乳酸である。塩酸等の強酸を配合した場合、耐圧容器の材質がアルミニウム、ブリキ、鉄などの金属である場合には腐食の原因となり、容器の内壁にプラスチックコーティング等を施す必要があるが、乳酸であればこのような問題は生じないからである。もっとも、ガラス容器や金属缶の中にポリエチレン等の袋が収納されている容器を用い、さらに、ステンレスバルブや原液との接触面が樹脂でできているバルブを用いれば、塩酸等の強酸を用いても腐食の問題は生じない。
ただし、乳酸以外の弱酸であるクエン酸、リンゴ酸、リン酸、酒石酸及びグルコン酸では原液のpHが5以下であっても経時的に沈殿を生じるので、塩酸等の強酸や乳酸を配合することなしに、これらの弱酸だけを配合する場合は本発明から除かれる。
In the present invention, an acid for adjusting the pH of the stock solution to 5 or less is essential. Examples of the acid include strong acids such as lactic acid or hydrochloric acid, but the present invention also includes a case where the acid is contained as a result of compounding in the form of a drug salt, for example, when lidocaine hydrochloride is compounded. Included in the acid formulation. Preferred as the acid is lactic acid. When a strong acid such as hydrochloric acid is blended, if the pressure vessel is made of a metal such as aluminum, tin, or iron, it will cause corrosion, and the inner wall of the vessel must be coated with a plastic coating. This is because such a problem does not occur. However, if you use a container in which a bag of polyethylene or the like is stored in a glass container or a metal can, and if you use a stainless steel valve or a valve whose contact surface with the stock solution is made of resin, use strong acid such as hydrochloric acid. However, the problem of corrosion does not occur.
However, citric acid, malic acid, phosphoric acid, tartaric acid and gluconic acid, which are weak acids other than lactic acid, cause precipitation over time even if the pH of the stock solution is 5 or less, so add strong acid such as hydrochloric acid or lactic acid. Without including only these weak acids, it is excluded from the present invention.
上述のように、本発明のエアゾール剤組成物の原液のpHは5以下であり、好ましくは2〜5である。pHが5を超えると経時的に沈殿物を生じ、噴射口の目詰まり等噴射性状の悪化を招来するので好ましくないからである。pHが2未満であると経時的な沈殿は生じないので噴射性状に影響はないが、皮膚に塗布した場合、皮膚に刺激が発生する可能性があるため好ましくない。 As described above, the pH of the stock solution of the aerosol composition of the present invention is 5 or less, preferably 2-5. This is because if the pH exceeds 5, precipitates are formed over time, leading to deterioration of the injection properties such as clogging of the injection port. If the pH is less than 2, precipitation with time does not occur, and there is no effect on the jetting properties. However, application to the skin is not preferable because irritation may occur in the skin.
ジメチルエーテルは噴射剤であり、噴射剤として、プロパン、ノルマルブタン、イソブタン等からなる液化石油ガス(LPG)を添加してもよい。
ジメチルエーテルを含有する噴射剤の配合(含有)量は、原液の1質量部に対して、1〜4質量部であり、1〜3質量部が好ましい。噴射剤の配合(含有)量が原液の1質量部に対して1質量部未満になると噴射剤量が少なすぎて持続的な冷感が減少するので好ましくない。4質量部を超えると噴射したエアゾールが霧状になり、持続的な冷却効果が得られないので好ましくない。
Dimethyl ether is a propellant, and liquefied petroleum gas (LPG) made of propane, normal butane, isobutane or the like may be added as a propellant.
The amount (inclusive) of the propellant containing dimethyl ether is 1 to 4 parts by mass, preferably 1 to 3 parts by mass with respect to 1 part by mass of the stock solution. When the blending (content) amount of the propellant is less than 1 part by mass with respect to 1 part by mass of the stock solution, the amount of the propellant is too small and the continuous cooling sensation decreases, which is not preferable. If the amount exceeds 4 parts by mass, the sprayed aerosol becomes mist-like and a continuous cooling effect cannot be obtained.
本発明のエアゾール剤組成物は、例えば、噴射剤以外の成分を加温、混合、攪拌して溶解又は均一に分散させて原液を調製した後、この原液を噴射剤と共に耐圧容器に充填することによってエアゾール剤として提供される。 In the aerosol composition of the present invention, for example, components other than the propellant are heated, mixed, stirred and dissolved or uniformly dispersed to prepare a stock solution, and then the pressure solution is filled with the stock solution together with the propellant. Provided as an aerosol.

試験例1
実施例1、4〜6、並びに比較例1〜10で調製した原液をガラス製耐圧瓶に充填し、バルブを装着して噴射剤を充填した。各サンプルを5℃で保存し、1カ月後の性状を観察した。結果を下表1に示す。
Test example 1
The stock solutions prepared in Examples 1, 4 to 6 and Comparative Examples 1 to 10 were filled in a glass pressure-resistant bottle, a valve was attached, and a propellant was filled. Each sample was stored at 5 ° C., and the properties after one month were observed. The results are shown in Table 1 below.
実験例1、4〜6では直後の噴射性状でシャーベット状を呈し、5℃で1カ月間保存してもガラス耐圧瓶内の製剤は無色澄明であった。 In Experimental Examples 1 and 4 to 6, the spray properties immediately after the sample showed a sherbet shape, and even when stored at 5 ° C. for 1 month, the preparation in the glass pressure-resistant bottle was colorless and clear.
比較例1は局所麻酔薬であるリドカインを配合していないエアゾール剤であり、pHが5超であっても製造直後の噴射性状でシャーベット状を呈し、5℃で1カ月間保存してもガラス耐圧瓶内の製剤の性状は無色澄明であった。 Comparative Example 1 is an aerosol that does not contain lidocaine, which is a local anesthetic, and even if the pH is over 5, it exhibits a sorbet shape immediately after production and is glass even if stored at 5 ° C. for 1 month. The properties of the preparation in the pressure bottle were clear and colorless.
比較例2はリドカインを配合し、pHを5超としたエアゾール剤であり、直後の噴射性状はシャーベット状であるが、5℃で1カ月間保存したときにガラス耐圧瓶内には沈殿物が発生した。 Comparative Example 2 is an aerosol agent containing lidocaine and having a pH of more than 5, and the jetting property immediately after is a sherbet shape, but when stored at 5 ° C. for 1 month, precipitates appear in the glass pressure-resistant bottle. Occurred.
比較例3は塩酸テルビナフィンを配合し、リドカインを配合していないエアゾール剤であり、pHが5超であっても製造直後の噴射性状でシャーベット状を呈し、5℃で1カ月間保存してもガラス耐圧瓶内の製剤の性状は無色澄明であった。これにより、沈殿の生成はリドカインの配合によることがわかった。 Comparative Example 3 is an aerosol agent containing terbinafine hydrochloride and no lidocaine, and even if the pH is more than 5, it exhibits a sorbet shape immediately after production and is stored at 5 ° C. for 1 month. The properties of the preparation in the glass pressure bottle were clear and colorless. Thereby, it was found that the formation of the precipitate was due to the blending of lidocaine.
比較例4は乳酸が配合されているが原液のpHが5以下にならず、ガラス耐圧瓶内には沈殿物が発生した。 In Comparative Example 4, lactic acid was blended, but the pH of the stock solution did not become 5 or less, and precipitates were generated in the glass pressure-resistant bottle.
比較例5〜9は乳酸以外の弱酸を配合しており原液のpHは5以下であるが、ガラス耐圧瓶内には沈殿物が発生した。これにより、クエン酸、リンゴ酸、リン酸、酒石酸、グルコン酸では原液のpHを5以下に調整しても沈殿の生成を抑制できないことが確認された。 In Comparative Examples 5 to 9, a weak acid other than lactic acid was blended, and the pH of the stock solution was 5 or less, but a precipitate was generated in the glass pressure-resistant bottle. Thus, it was confirmed that citric acid, malic acid, phosphoric acid, tartaric acid, and gluconic acid could not suppress the formation of precipitates even when the pH of the stock solution was adjusted to 5 or lower.
比較例10は塩酸プロカインを配合し、pHを5超としたエアゾール剤であり、直後の噴射性状はシャーベット状であるが、5℃で1カ月間保存したときにガラス耐圧瓶内には沈殿物が発生した。 Comparative Example 10 is an aerosol agent formulated with procaine hydrochloride and having a pH of more than 5. Immediately after the jetting property is a sherbet, there is a precipitate in the glass pressure bottle when stored at 5 ° C. for one month. There has occurred.
本発明により、リドカイン又はプロカインを含有し、さらに噴射時にシャーベット状の泡沫を形成するため、極めて優れた鎮痒効果を発揮するエアゾール剤を提供することが期待される。さらにテルビナフィン等の抗真菌薬を配合することにより、治療効果の増強された抗真菌エアゾール剤を提供することも期待される。
According to the present invention, since lidocaine or procaine is contained, and a sherbet-like foam is formed at the time of injection, it is expected to provide an aerosol agent that exhibits an extremely excellent antipruritic effect. Furthermore, it is also expected to provide an antifungal aerosol agent with enhanced therapeutic effect by incorporating an antifungal agent such as terbinafine.
