Definitions
- the present invention relates to an itch inhibitor containing a compound having a chymase inhibitory activity as an active ingredient. Further, the present invention relates to a itch-inhibiting effect-enhancing agent comprising a compound having a chymase inhibitory activity as an active ingredient, and enhancing the itch-inhibiting effect of a steroid agent.
- “Itching” refers to the sensation, or pruritus, caused by a weak stimulus to the pain points in the skin and mucous membranes. Itching has characteristics that differ from pain in that it occurs only on the body surface and in the oral cavity. Furthermore, itching is markedly different from pain in that it is extremely painful to withstand the discomfort caused by it, even if it is mild. Severe itching can even impair daily life, and in very severe cases requires treatment with hospitalization.
- Arterial dermatitis is a disease that develops specific skin symptoms with the characteristic of persistent itching, and its diagnostic criteria are (1) pruritus, (2) rash, (3) chronic and recurrent It satisfies the following three points.
- Non-allergic factors include physical factors, such as skin dryness, sweating, pressurization and weighting of the skin, and rupture of the skin.
- allergic factors include, for example, contact with environmental factors, food allergens, mites, house dust, pet hair, metals and other allergens present in the environment, aspiration and ingestion. .
- non-allergic factors or allergic factors are further linked to a genetic predisposition such as an allergic predisposition or a dry skin predisposition, that is, atopic predisposition, it leads to the development of atopic dermatitis.
- correction of skin barrier disorder and control of skin including suppression of itching are considered as one of the important pillars, and in this case, it depends on IgE. It is important to control both itching and itching due to non-allergic factors simultaneously.
- Antihistamines anti-allergic drugs, which have been widely used in the past because they are effective in suppressing itch, are not effective in patients with moderate or more persistent itch, and steroids Not only are they often only topical or are ineffective, they can also cause side effects such as central depression and liver damage.
- the present invention has been made in view of the above circumstances, and aims to provide an excellent itching inhibitor.
- the present inventors have conducted intensive studies to achieve the above object, and surprisingly found that a compound having a chimase inhibitory action has an excellent itching inhibitory action suitable for the above purpose.
- the present inventors have further found that the combined use of a steroid inhibitor and a itch inhibitor containing a compound having a chymase inhibitory effect enhances the itch inhibitory effect of the steroid agent, and completed the present invention.
