ニキビは90%以上の青年男女が経験するとされる皮膚疾患であるが、思春期の生理現象ということで、かつては積極的な治療がされていなかった。しかし、最近では、思春期を過ぎてのニキビも大人のニキビとして注目されている。   Acne is a skin disease that more than 90% of adolescent men and women will experience, but because it is an adolescent physiological phenomenon, it has not been treated aggressively. Recently, however, acne after puberty has attracted attention as adult acne.

ニキビは脂腺性毛包を侵す慢性炎症性疾患で、主として思春期に発症し、その病因は内因性、外因性因子が数多く複雑に関連し合っている。また、その発症機序にはいくつかの段階があり、大きく二つの段階に分けることができる。第一段階は面ほう形成であり、第二段階は炎症惹起である。このうち面ほう形成過程では、1)主として男性ホルモン作用による皮脂分泌の亢進、2)毛嚢漏斗部の角化異常、3)毛包内細菌による皮脂中の中性脂肪の遊離脂肪酸への分解亢進が、また炎症惹起過程では、P. acnes由来の細胞外炎症誘発物質、とくに好中球遊走化因子が重要である。   Acne is a chronic inflammatory disease that affects sebaceous hair follicles and develops mainly in puberty. Its etiology is intrinsically related to many exogenous factors. There are several stages in the onset mechanism, and it can be roughly divided into two stages. The first stage is surface formation and the second stage is inflammation. Among these, in the process of surface formation, 1) increased sebum secretion mainly due to male hormone action, 2) abnormal keratinization of hair follicle funnel, and 3) degradation of neutral fat in sebum into free fatty acids by bacteria in hair follicles. In the process of promoting inflammation and inducing inflammation, P. acnes-derived extracellular inflammation-inducing substances, particularly neutrophil chemotactic factors are important.

ニキビの発生段階に合わせて、治療法は異なる。非炎症性の皮疹である面ほうに対してはイオウ局所外用療法が基本であり、原則的に全身内服(経口)療法は行わない。特に、イオウ含有ローションはその刺激作用により角質の剥離を起こし、軽症のニキビを改善させる。また、特殊な治療法として、総合代謝性ホルモン剤や経口避妊薬の全身内服(経口)療法もある。炎症性の皮疹である赤色丘疹、膿ほうに対しては局所外用療法および全身内服(経口)療法が主体となる。局所外用療薬としては非ステロイド系抗炎症外用剤、外用抗菌剤、そして、経口薬としては抗菌剤や漢方薬が用いられる。   Treatment varies depending on the stage of acne. Topical sulfur therapy is fundamental for non-inflammatory skin eruptions, and systemic (oral) therapy is not performed in principle. In particular, a sulfur-containing lotion causes exfoliation of the keratin due to its stimulating action and improves mild acne. In addition, as a special treatment, there are systemic oral (oral) therapies of comprehensive metabolic hormones and oral contraceptives. For red papules and pus, which are inflammatory eruptions, local topical therapy and systemic (oral) therapy are mainly used. Non-steroidal anti-inflammatory external preparations and external antibacterial agents are used as topical external medicines, and antibacterial agents and traditional Chinese medicines are used as oral preparations.

しかしながら、これらの方法は、皮膚科医の診察を受けた後に取られる手法であり、欧米人に比べて比較的軽症のニキビが多い日本人では、薬局で市販薬を購入するなどして自己治療している場合が多く見られる。また、補助的全身内服(経口)療法としてビタミン剤、便通調整剤、精神安定剤などが用いられることがある。ビタミンに関してはその有効量がビタミンA 300,000〜400,000国際単位/日、ビタミンB 30〜60mg/日、そしてビタミンE 150〜300mg/日のように多量のビタミンが必要とされ、ビタミンAに関しては副作用も心配される。市販されているものでは、エーザイ株式会社製「チョコラBBエース」のようなビタミンB群複合剤(参考文献:基礎と臨床、16(11)、495(1982))やカネボウ薬品社製「ヨクイノーゲン」のような漢方剤とビタミンの複合剤(参考文献:基礎と臨床、21(6)、565(1987))などが、内服によりニキビ症状に効果があることが報告されている。しかし、アミノ酸を利用した例は全く知られていなかった。 However, these methods are taken after consulting a dermatologist. For Japanese people with relatively mild acne compared to Westerners, self-treatment such as purchasing over-the-counter drugs at pharmacies Many cases are seen. In addition, vitamins, fecal adjustment agents, tranquilizers, etc. may be used as auxiliary systemic (oral) therapy. For vitamins, effective amounts of vitamin A 300,000-400,000 international units / day, vitamin B 6 30-60 mg / day, and vitamin E 150-300 mg / day are required in large quantities, Regarding A, side effects are also a concern. Commercially available products include vitamin B complex (such as “Chocola BB ace” manufactured by Eisai Co., Ltd. (reference: basic and clinical, 16 (11), 495 (1982)) and “Yokuinogen” manufactured by Kanebo Pharmaceutical Co., Ltd. It has been reported that Chinese medicine and vitamin combination agents such as (reference: basic and clinical, 21 (6), 565 (1987)) have an effect on acne symptoms by internal use. However, no examples using amino acids have been known.

さて、本発明者は、多年各種アミノ酸類の栄養作用や生理作用の研究に従事し、その間、特定のアミノ酸の特定の割合の組成物が栄養状態の改善に有効なことを見出し(後掲特許文献1)、あるいはまた育毛作用に優れることを見出し、これについては既に特許出願をしている(特願2003−199038)。しかしながら、ニキビに対してアミノ酸が効果を示すという知見はなかった。
