Preferably the therapeutic agent further contains a mucopolysaccharide such as hyaluronic acid (salt).

Description

本発明は、皮膚外用剤に関する。さらに詳しくは、イブプロフェンピコノールとイソプロピルメチルフェノールとサリチル酸とを有効成分として含有するニキビ治療薬に関するものである。   The present invention relates to an external preparation for skin. More specifically, the present invention relates to a therapeutic agent for acne containing ibuprofen piconol, isopropylmethylphenol and salicylic acid as active ingredients.

ニキビは尋常性ざ瘡と呼ばれ、毛穴に皮脂が詰まり、これにアクネ菌が感染し炎症を起すものである。ニキビは慢性の皮膚疾患であるが、その発症の病理の詳細はいまだ不明な点が多い。
ニキビは主として思春期に発現する皮膚疾患であったが、近年「大人にきび」と言われるように思春期後もニキビに悩ませされる人が増えてきている。また「大人にきび」「思春期にきび」によらず、顔面に発生することから、見ためにわかりやすく、かつ炎症を起すと痛みが伴うため、ファンデーション等で隠す・つぶす・触るなど悪化させる行動をしがちであり、その結果、ニキビ跡を残してしまうという問題があった。このことからもニキビは早い治癒が望まれ、より高い治療効果を有するニキビ治療薬が求められている。
ニキビ治療の有効成分としては、抗炎症剤、殺菌剤、角質軟化剤、皮脂抑制剤などが知られ、これらを組み合わせた治療薬が開発されている。
イブプロフェンピコノールは、外用の非ステロイド剤として初めて尋常性ざ瘡の効能が認められた薬剤である。抗炎症、鎮痛作用に加え、リパーゼ及び細菌自身のリパーゼ活性の抑制作用をもっていることから、イブプロフェンピコノール配合の外用剤はニキビに対して優れた効果を持つといえる。
特許文献1には、イブプロフェンピコノールの効果を高めるため、イブプロフェンピコノールとイソプロピルメチルフェノールやビタミンEを併用した水中油型エマルジョンとしたニキビ治療剤が提案されている。
一方、特許文献2には、甘草から抽出された油溶性抽出物と、角質剥離剤及び/又は抗炎症剤とを併用したニキビ治療用組成物が提案されている。
Acne is called acne vulgaris, and the pores are clogged with sebum, which infects acne bacteria and causes inflammation. Acne is a chronic skin disease, but the details of the pathology of its development are still unclear.
Acne was a skin disease mainly manifested in puberty, but in recent years, an increasing number of people are suffering from acne after puberty, as it is called “adult acne”. Also, it occurs on the face regardless of “adult acne” or “adolescent acne”, so it is easy to see, and it causes pain when inflamed. As a result, there was a problem of leaving an acne scar. For this reason, acne is desired to be cured quickly, and a therapeutic agent for acne having a higher therapeutic effect is demanded.
As active ingredients for acne treatment, anti-inflammatory agents, bactericides, keratin softeners, sebum suppressants and the like are known, and therapeutic agents combining these have been developed.
Ibuprofen piconol is the first non-steroidal drug with the efficacy of acne vulgaris. In addition to anti-inflammatory and analgesic effects, it has an inhibitory action on lipase and lipase activity of bacteria itself, so it can be said that an external preparation containing ibuprofen piconol has an excellent effect on acne.
Patent Document 1 proposes an acne treatment agent in the form of an oil-in-water emulsion in which ibuprofen piconol is combined with isopropylmethylphenol and vitamin E in order to enhance the effect of ibuprofen piconol.
On the other hand, Patent Document 2 proposes a composition for treating acne using an oil-soluble extract extracted from licorice and a keratin exfoliant and / or an anti-inflammatory agent.

本発明は、従来よりも高い治療効果を有するニキビ治療薬を提供することを目的とする。   An object of this invention is to provide the acne therapeutic agent which has a therapeutic effect higher than before.

本発明者らは、上記目的を達成するために鋭意検討を行った結果、イブプロフェンピコノールと、イソプロピルメチルフェノールと、サリチル酸及を併用することによって、より優れたニキビ治療効果が得られることを知見し、本発明を完成した。また、さらにヒアルロン酸(塩)等のムコ多糖を添加することによって、前記薬物の刺激感を抑制し使用感に優れたニキビ治療薬が得られることを見出した。   As a result of intensive studies to achieve the above object, the present inventors have found that a combination of ibuprofenpiconol, isopropylmethylphenol, salicylic acid, and the like can provide a better acne treatment effect. The present invention has been completed. Furthermore, it has been found that by adding mucopolysaccharides such as hyaluronic acid (salt), a therapeutic agent for acne can be obtained which suppresses the irritation of the drug and has an excellent usability.

従って、本発明は。
<1>(A)イブプロフェンピコノール、(B)イソプロピルメチルフェノール、及び(C)サリチル酸を含有することを特徴とするニキビ治療薬。

Therefore, the present invention.
<1> An acne remedy comprising (A) ibuprofen piconol, (B) isopropylmethylphenol, and (C) salicylic acid.
<2> The acne therapeutic agent according to <1>, further comprising (D) a mucopolysaccharide.
I will provide a.

本発明により、優れたニキビ治療効果を有し、しかも刺激感が抑制されたニキビ治療薬が得られる。   According to the present invention, a therapeutic agent for acne is obtained which has an excellent acne treatment effect and suppresses a sense of irritation.

本発明で使用されるイブプロフェンピコノールは、医薬外用剤として使用されるものであれば特に制限なく用いることができ、例えば日本薬局方外医薬品規格に収載されているものを使用することができる。イブプロフェンピコノールの濃度は、本発明のニキビ治療薬組成物中、0.01〜10質量%の範囲であることが好ましく、より好ましくは0.1〜5.0質量%である。イブプロフェンピコノールの濃度が0.1質量%未満では、ニキビの原因菌であるアクネ菌に対する殺菌効果が弱くなるため、治療効果が十分でない場合がある。また、イブプロフェンピコノールの濃度が高いと、患部への刺激が強くなるため好ましくない。   The ibuprofen piconol used in the present invention can be used without particular limitation as long as it is used as a pharmaceutical external preparation. For example, those listed in the Japanese Pharmacopoeia Standards for Pharmaceuticals can be used. The concentration of ibuprofen piconol is preferably in the range of 0.01 to 10 mass%, more preferably 0.1 to 5.0 mass% in the acne therapeutic agent composition of the present invention. If the concentration of ibuprofen piconol is less than 0.1% by mass, the bactericidal effect against acne that is a cause of acne is weakened, so the therapeutic effect may not be sufficient. Moreover, since the irritation | stimulation to an affected part becomes strong when the density | concentration of ibuprofen piconol is high, it is unpreferable.

本発明で用いられるイソプロピルメチルフェノールは、医薬外用剤として使用されるものであれば特に制限なく用いることができる。イソプロピルメチルフェノールの濃度は、本発明のニキビ治療薬組成物中、0.01〜5質量%の範囲であることが好ましく、より好ましくは0.05〜3質量%である。イソプロピルメチルフェノールの濃度が0.01質量%未満では、ニキビの原因菌であるアクネ菌に対する殺菌効果が弱くなるため、治療効果が十分でない場合がある。また、イソプロピルメチルフェノールの濃度が高いと、患部への刺激が強くなるため好ましくない。   The isopropylmethylphenol used in the present invention can be used without particular limitation as long as it is used as a pharmaceutical external preparation. The concentration of isopropylmethylphenol is preferably in the range of 0.01 to 5% by mass, more preferably 0.05 to 3% by mass in the acne therapeutic agent composition of the present invention. If the concentration of isopropylmethylphenol is less than 0.01% by mass, the bactericidal effect against acne that is the cause of acne is weakened, so the therapeutic effect may not be sufficient. Moreover, since the irritation | stimulation to an affected part becomes strong when the density | concentration of isopropylmethylphenol is high, it is unpreferable.

本発明で用いられるサリチル酸は、医薬外用剤として使用されるものであれば特に制限なく用いることができる。本発明において、サリチル酸は、患部の皮膚の角質を軟化させ、イブプロフェンピコノールやイソプロピルメチルフェノールの患部への浸透を促進し、治療効果を高める作用を発揮する。サリチル酸の濃度は、本発明のニキビ治療薬組成物中、0.01〜5質量%の範囲であることが好ましく、より好ましくは0.05〜3質量%である。サリチル酸の濃度が0.01質量%未満では、患部の皮膚の軟化が不十分でなくニキビ治療効果の向上が十分得られない場合がある。また、サリチル酸の濃度が高いと、患部への刺激が強くなるため好ましくない。   The salicylic acid used in the present invention can be used without particular limitation as long as it is used as a pharmaceutical external preparation. In the present invention, salicylic acid softens the skin of the affected area, promotes penetration of ibuprofen piconol or isopropylmethylphenol into the affected area, and exerts an effect of enhancing the therapeutic effect. The concentration of salicylic acid is preferably in the range of 0.01 to 5% by mass, more preferably 0.05 to 3% by mass in the acne therapeutic agent composition of the present invention. If the concentration of salicylic acid is less than 0.01% by mass, the affected area may not be sufficiently softened and the acne treatment effect may not be sufficiently improved. Moreover, since the irritation | stimulation to an affected part becomes strong when the density | concentration of a salicylic acid is high, it is unpreferable.

本発明のニキビ治療薬には、上記の薬物の他、ムコ多糖を含有することが好ましい。ムコ多糖を併用することによって、前記薬物に由来する刺激を緩和することができ、また、保湿効果によって、本発明のにきび治療薬塗布部の皮膚をなめらかな状態に保つことができる。使用するムコ多糖としては、ヒアルロン酸及び/又はその塩、ヘパリン類似物質、コンドロイチン多硫酸及び/又はその塩等が挙げられる。前記中、ヒアルロン酸及び/又はその塩が好ましく、ヒアルロン酸ナトリウムが特に好ましい。
ムコ多糖の濃度は、本発明のニキビ治療薬組成物中、0.001〜10質量%の範囲であることが好ましく、より好ましくは0.01〜5質量%である。ムコ多糖の濃度が0.001質量%未満では、刺激緩和、塗布部の皮膚のなめらかさが十分得られない。また、ムコ多糖の濃度が高いと、ベタツキを生じるなど、使用感を損なう場合がある。
The acne therapeutic agent of the present invention preferably contains mucopolysaccharide in addition to the above drugs. By using mucopolysaccharide in combination, the stimulation derived from the drug can be alleviated, and the skin of the acne therapeutic agent application part of the present invention can be kept in a smooth state by the moisturizing effect. Examples of the mucopolysaccharide used include hyaluronic acid and / or a salt thereof, heparin-like substance, chondroitin polysulfate and / or a salt thereof, and the like. Among these, hyaluronic acid and / or a salt thereof are preferable, and sodium hyaluronate is particularly preferable.
The concentration of the mucopolysaccharide is preferably in the range of 0.001 to 10% by mass, more preferably 0.01 to 5% by mass in the acne therapeutic agent composition of the present invention. When the concentration of the mucopolysaccharide is less than 0.001% by mass, the irritation can be alleviated and the smoothness of the skin of the application part cannot be obtained sufficiently. Moreover, when the concentration of mucopolysaccharide is high, the feeling of use may be impaired, for example, stickiness may be generated.

本発明のニキビ治療薬中には、上記成分の他に、通常医薬外用剤に配合される各種成分、例えば、ニキビ治療薬に配合され得る各種薬物、界面活性剤、溶解補助剤、保湿剤、増粘剤、防腐剤、酸化防止剤、キレート剤、pH調整剤、香料、色素、紫外線吸収・散乱剤、ビタミン類、アミノ酸類、溶媒、油性基材等を配合することができる。   In the acne treatment drug of the present invention, in addition to the above-mentioned components, various components that are usually blended in a pharmaceutical preparation for external use, for example, various drugs that can be blended in acne treatment drugs, surfactants, solubilizing agents, humectants, Thickeners, preservatives, antioxidants, chelating agents, pH adjusters, fragrances, dyes, ultraviolet light absorbing / scattering agents, vitamins, amino acids, solvents, oily base materials and the like can be blended.
