DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an external preparation for treating or preventing skin pigmentation disorder or scarring.

[0002]

2. Description of the Related Art Currently, steroidal anti-inflammatory drugs used for skin diseases have an excellent therapeutic effect. However, when used as an external preparation for a long period of time, the side effects of peculiar skin symptoms such as acne. During the administration period or after the administration is stopped, pigmentation such as melasma and sparrow eggs and scarring are observed in the skin condition of the patient.

[0003] On the other hand, although not fatal in daily life, scars as sequelae of burns, herpes, keloids, pox, etc., and pigmentation or / and spots due to ultraviolet irradiation, cosmetics, etc., have a great adverse effect on mental health. Exert. Especially in women, skin tissue disorders on the face are significant.

For example, although corticosteroids, ie, steroidal anti-inflammatory drugs, have excellent therapeutic effects, long-term oral administration causes renal failure, diabetes, hypothalamus, pituitary gland, suppression of adrenocortical functions, and the like. And other systemic side effects. Even in the form of an external preparation, topical exacerbation of skin infections and corticosteroids are currently being administered mainly to steroids for treatment of skin diseases in medical institutions and the like.

On the other hand, a typical compound included in the nitroimidazole compound contained in the external preparation for treating or preventing skin pigmentation disorder or scarring of the present invention is metronidazole [2- (2-methyl). -5-nitro-1-
Imidazolyl) ethanol], secnidazole [1-
(2-methyl-5-nitro-1-imidazolyl) propan-2-ol], panidazole [4- (2- (2-methyl-5-nitro-1-imidazolyl) ethyl) pyridine], dimetridazole [1 , 2-dimethyl-5-nitro-1H-imidazole], lonidazole [2-carbamoyloxymethyl-1-methyl-5-nitro-1H-
Imidazole], ipronidazole [1-methyl-2-
(1-methylethyl) -5-nitro-1H-imidazole] and ornidazole [1- (3-chloro-2-hydroxypropyl) -2-methyl-5-nitroimidazole].

Metronidazole is a nitroimidazole derivative synthesized by Jacob of Rhone Poulin Roller in 1957, and was found by Cosar and Julou to have a strong anti-trichomonas effect.
In 9 years, Durel reported for the first time that Trichomonas protozoa disappeared using this drug in human trichomoniasis. Also,
It has strong antibacterial activity against dysentery amoeba. Furthermore, when administered orally or topically to other anaerobic bacteria, it is reported to have a bactericidal effect, and the mechanism of action is that the nitro group of metronidazole is reduced by microorganisms, This is considered to cause functional disorders such as double-strand breaks in the DNA of microorganisms and to control division and growth.

[0007] Secnidazole is also an analog of metronidazole found by Rhone Poulin Roller, lonidazole is found by Merck, and ornidazole and ipronidazole are Hoffman la.
It is a compound discovered by Roche and shows antiprotozoal activity including dimetridazole and panidazole.

[0010] Furthermore, the effect of metronidazole on inflammation is that an external preparation of metronidazole is effective for inflammatory skin diseases such as rosacea (WO 88/06888,
International Publication WO89 / 06537, International Publication WO94 / 08350, International Publication WO96 / 01117, International Publication WO98 / 27960) are known. In addition, according to Mykosen, 27 , 475 (1984), it is believed that metronidazole exhibits a therapeutic effect at a concentration that does not show antibacterial activity against P. ovale etc. due to anti-inflammatory activity,
According to Br. J. Dermatol., 114, 231 (1986), metronidazole has activity to suppress the production of reactive oxygen species, and metronidazole is effective for rosacea in part because of its anti-inflammatory activity. , 60 , 75 (1975)
Has shown that oral administration of metronidazole is effective for foot skin ulcers.

However, the nitroimidazole compounds, pharmacologically acceptable salts, esters or other derivatives thereof used in the present invention have been used for the treatment, amelioration or prevention of skin pigmentation disorders or scarring. There is no example.
