Description

本発明は、アレルギー性鼻炎症状、特に鼻づまりの症状を予防する上で有用な医薬組成物に関する。   The present invention relates to a pharmaceutical composition useful for preventing allergic rhinitis symptoms, particularly symptoms of nasal congestion.

近年、アレルギー性疾患の罹患者数は増加の一途を辿っており、特にアレルギー性鼻炎の罹患者の増加は著しいものがある。抗原の増加のみならず、大気汚染といった周囲の環境の変化が、アレルギーの増加の原因であると推定されている。アレルギー性疾患は外部抗原に対する生体側の過剰防衛反応であり、抗体産生細胞等の過剰対応が原因であるとされている。すなわち、人体の持つ抵抗力の過剰反応ということができる。このようなアレルギー性疾患の治療では、従来、抗ヒスタミン剤やステロイド剤等が投与されてきた(非特許文献1)。また、予防に対しても、化学伝達遊離抑制剤が投与されてきた(非特許文献1)。
アレルギー性鼻炎の予防に対しては、近年注目されており、縮合ピリダジン誘導体(特許文献1参照)、ピペリジン誘導体(特許文献2、3参照)等、アレルギー性鼻炎予防薬が開発されてきている。しかしながら、これらの薬剤を用いても充分な効果は得られず、また副作用が強く、安全性の点でも問題があった。
一方、抗プラスミン剤を利用して血管収縮剤により発現する鼻炎症状を抑える技術が公開されている(特許文献4参照)。しかしながら、この鼻炎症状はアレルギー性鼻炎とは異なるものであり、抗プラスミン剤が従来のアレルギー性鼻炎予防用の医薬組成物を超える優れたアレルギー性鼻炎の予防作用を得たという報告はない。

In recent years, the number of people suffering from allergic diseases has been increasing. In particular, the number of people suffering from allergic rhinitis has increased significantly. Changes in the surrounding environment such as air pollution as well as an increase in antigens are presumed to cause an increase in allergies. Allergic diseases are excessive defense reactions on the living body side against external antigens, and are considered to be caused by excessive responses such as antibody-producing cells. In other words, it can be said that the human body has an excessive reaction of resistance. In the treatment of such allergic diseases, antihistamines, steroids and the like have been conventionally administered (Non-patent Document 1). In addition, chemical transmission release inhibitors have been administered for prevention (Non-patent Document 1).
In recent years, attention has been paid to the prevention of allergic rhinitis, and allergic rhinitis preventive drugs such as condensed pyridazine derivatives (see Patent Document 1) and piperidine derivatives (see Patent Documents 2 and 3) have been developed. However, even if these drugs are used, a sufficient effect cannot be obtained, and there are problems in terms of safety due to strong side effects.
On the other hand, a technique for suppressing nasal inflammation caused by a vasoconstrictor using an antiplasmin agent has been disclosed (see Patent Document 4). However, this nasal inflammation is different from allergic rhinitis, and there is no report that an antiplasmin agent has obtained an excellent allergic rhinitis preventive effect that exceeds the conventional pharmaceutical composition for preventing allergic rhinitis.

試験例1Test example 1

以下の方法により、被験物質の鼻腔抵抗抑制作用を測定した。
モルモットをウレタン(1.4g/kg、i.p.)で麻酔し、背位に固定する。呼吸維持のため気管を切開して肺側に気管カニューレを挿入する。さらに気管切開部より鼻咽喉内に気管カニューレを挿入し、シリコンチューブを介して、人工呼吸器(141A、New England Medical Instruments Inc.)に接続して、4mL/回、70回/分の頻度で鼻腔内に通気する。なお、口腔内への送気漏れを防ぐために、アロンアルフアA「三共」で切歯管を閉じる。鼻腔内圧は鼻腔内に挿入したチューブの側枝に接続したトランスデューサー(DP−45−16−2114、Validyne、Gould)を用いて測定する。人工呼吸器と鼻腔内チューブとの間に接続した超音波ネブライザー(NE−U12、オムロン)により0.1mg/mLのヒスタミン溶液(または生理食塩水)をエアロゾル化し、鼻腔内に5分間送気する。ヒスタミン吸入前(pre)および吸入終了後0、1、3、5、7、10、15、20、25および30分の鼻腔内圧を測定する。鼻腔内圧、反応曲線下面積(AUC)および薬物の抑制率については下記のように算出する。なお、被験物質及び媒体(注射用水)の投与はヒスタミン(または生理食塩水)の送気1時間前に経口投与する。
The nasal resistance suppression effect of the test substance was measured by the following method.
Guinea pigs are anesthetized with urethane (1.4 g / kg, ip) and fixed in the dorsal position. In order to maintain breathing, the trachea is opened and a tracheal cannula is inserted on the lung side. Further, a tracheal cannula is inserted into the nasopharynx from the tracheostomy and connected to a ventilator (141A, New England Medical Instruments Inc.) via a silicone tube at a frequency of 4 mL / time and 70 times / minute. Vents into the nasal cavity. In order to prevent air leakage into the oral cavity, the incisor tube is closed with Aron Alpha A “Sankyo”. Intranasal pressure is measured using a transducer (DP-45-16-2114, Validyne, Gould) connected to the side branch of a tube inserted into the nasal cavity. The 0.1 mg / mL histamine solution (or physiological saline) is aerosolized by an ultrasonic nebulizer (NE-U12, OMRON) connected between the ventilator and the intranasal tube, and is infused into the nasal cavity for 5 minutes. . Intranasal pressure is measured before histamine inhalation (pre) and at the end of inhalation 0, 1, 3, 5, 7, 10, 15, 20, 25 and 30 minutes. The intranasal pressure, area under the response curve (AUC), and drug inhibition rate are calculated as follows. The test substance and vehicle (water for injection) are orally administered 1 hour before insufflation of histamine (or physiological saline).

1)鼻腔内圧
i)鼻腔内圧上昇値(pre値との差)
ヒスタミン吸入終了後の各時点での鼻腔内圧から吸入前のそれを差し引いた値をその時点における鼻腔内圧上昇値とする。数値はhPaに換算して表記する(1.0cmHO=0.981hPa)。
ii)反応曲線下面積(AUC)
上記i)で求めた吸入終了後0〜30分間における経時的な鼻腔内圧上昇値から、AUC0−30(hPa・min)を算出する。
2)薬物の抑制率
ヒスタミン吸入終了後におけるAUC0−30において、対照群(V)および被験物質群(A)におけるヒスタミン吸入後の値ならびに生理食塩液吸入終了後の値(C)から以下の式により抑制率を算出し、鼻腔内圧上昇の抑制を比較する。

Figure 2005343846
1) Intranasal pressure i) Increased intranasal pressure (difference from pre value)
The value obtained by subtracting that before inhalation from the intranasal pressure at each time point after histamine inhalation is taken as the increase in intranasal pressure at that time point. Numerical values are expressed in terms of hPa (1.0 cmH 2 O = 0.981 hPa).
ii) Area under the reaction curve (AUC)
AUC 0-30 (hPa · min) is calculated from the increase in intranasal pressure over time from 0 to 30 minutes after the end of inhalation obtained in i) above.
2) Drug inhibition rate In AUC 0-30 after the end of histamine inhalation, the value after inhalation of histamine and the value after end of inhalation of physiological saline (C) in the control group (V) and the test substance group (A) are as follows. The suppression rate is calculated by the equation, and the suppression of the increase in intranasal pressure is compared.
