Abstract
Description
【0001】
【発明の属する技術分野】
本発明は、エフェドリン類と、フェニルプロピオン酸系解熱消炎鎮痛剤を含有するくしゃみ抑制用医薬に関する。
【0002】
【従来の技術】
感冒や花粉症などのアレルギー性鼻炎の各症状においてくしゃみが多発する。そのため、感冒薬や鼻炎用薬にはくしゃみ抑制用に抗ヒスタミン剤又は抗アレルギー剤が配合されることが一般的である。
【0003】
しかし、抗ヒスタミン剤は速効性があるものの眠気や倦怠感を催すという副作用がある。なお、眠気などの中枢神経抑制作用を大幅に軽減させた第二世代の抗ヒスタミン剤が既に使用されているが、眠気を自覚しなくても、作業効率の低下など中枢神経機能の抑制(これはimpaired performanceと呼ばれる)がみられ、車の運転や学業などへの影響は大きい。気づかないうちに認知機能などが低下している例は結構多く、抗ヒスタミンにおけるimpaired performanceは、現代人にとって最も憂慮すべき深刻な副作用とさえ言われる(例えば、非特許文献1参照。)。
【0004】
抗アレルギー剤は、抗ヒスタミン剤の有する副作用は少ない反面、速効性がなく薬効発現には時間がかかるという問題があった。
【0005】
一方、フェニルプロピオン酸系解熱消炎鎮痛剤がくしゃみ抑制に効果があることが、知られている(例えば、急性上気道炎に対するLoxoprofen sodium(CS−600E)の臨床評価について、非特許文献2参照。)
【0006】
【非特許文献1】
2002年2月22日付,薬事日報
【非特許文献2】
臨床医薬9巻10号(10月)(1993)
【0007】
【発明が解決しようとする課題】
本発明者等は、くしゃみ抑制につき鋭意検討した結果、フェニルプロピオン酸系解熱消炎鎮痛剤に、それ自身ではくしゃみ抑制作用を持たないエフェドリン類を加えると、くしゃみ抑制効果が増強することを見出して、本発明を完成させた。
【0008】

【発明の効果】
本発明のエフェドリン類とフェニルプロピオン酸系解熱消炎鎮痛剤を含有する医薬は、くしゃみ抑制用の医薬(特に、感冒、又は、鼻炎(好ましくは、アレルギー性鼻炎)におけるくしゃみの抑制に用いるもの)として有用である。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medicament for suppressing sneezing containing ephedrines and a phenylpropionic acid-based antipyretic anti-inflammatory drug.
[0002]
[Prior art]
Sneezing frequently occurs in each symptom of allergic rhinitis such as cold and hay fever. For this reason, it is common to add an antihistamine or an antiallergic agent to a common cold drug or a drug for rhinitis to suppress sneezing.
[0003]
However, although antihistamines are quick-acting, they have the side effect of causing drowsiness and malaise. Although a second-generation antihistamine which has significantly reduced central nervous system depressing effects such as drowsiness has already been used, suppression of central nervous system functions such as a decrease in work efficiency without impairment of drowsiness (this is impaired) performance), which has a large effect on driving a car and studying. There are quite a few cases in which cognitive functions and the like are lowered without notice, and impaired performance in antihistamine is even said to be the most alarming and serious side effect for modern humans (for example, see Non-Patent Document 1).
[0004]
The antiallergic agent has few side effects of the antihistamine, but has a problem in that it has no immediate effect and takes a long time to develop a drug effect.
[0005]
On the other hand, it is known that a phenylpropionic acid-based antipyretic anti-inflammatory analgesic is effective in suppressing sneezing (for example, see Non-Patent Document 2 for clinical evaluation of Loxoprofen sodium (CS-600E) for acute upper respiratory inflammation). )

Example (4) Syrup (1) Ingredient
[Table 4]
(2) Production method Take the above components and amounts, prepare a syrup according to the Japanese Pharmacopoeia General Rules for Syrups, and fill in a brown glass bottle to produce a syrup.
(Test Example 1 ) Inhibitory effect of sneezing on antigen stimulation (1) Test substance The test substance was used as a suspension with 0.5% tragacanth solution on the test day. The dose of the test substance was 2.0 mL per 1 kg of body weight, and the control group received the same amount of 0.5% tragacanth solution.
(2) Test animals Hartley male guinea pigs, 5 weeks old (purchased from SLC Japan), were subjected to solid feed and tap water using an environmental control breeding apparatus (manufactured by CLEA Japan) at a temperature of 20 to 26 ° C and a humidity of 35 to 65%. And used after preliminary rearing under lighting conditions of 7:00 to 19:00.
(3) Test Method (1) Preparation of Actively Sensitized Guinea Pig A guinea pig of 6 weeks of age is immunized by subcutaneously administering 0.5 mL of an antigen solution (egg albumin 50 mg / mL: Sigma Chemical Co.) into the back and intraperitoneally. One week later, a booster immunization is performed by similarly administering the same amount of the antigen. Seven to nine days after the boost, fast for about 24 hours and test as active sensitized guinea pigs.
(2) Induction of sneezing induced by the antigen The health of the animals is checked and selected, and the animals are sorted so that the weight of 5 animals per group is averaged. Next, 0.1 mL of the antigen solution (50 mg / mL) is instilled into both nasal passages of the guinea pig. Thereafter, the symptoms are observed for 15 minutes, and the number of sneezes is counted to determine the intensity of the antigen-induced nasal symptoms.
{Circle around (3)} Inhibition of test substance The test substance is administered using an oral probe one hour before the nasal drop of the antigen described in the above item [2]. The sneezing suppression rate (%) is calculated by the following formula.
[0027]
Inhibition rate (%) = [1−average number of sneezing in test substance administration group / average number of sneezing in control group] × 100
(4) Test Results Table 5 shows the results of the sneezing inhibition rate of pseudoephedrine hydrochloride or loxoprofen sodium alone and in combination.
[0028]
[Table 5]
Test substance (mg / Kg) Sneezing suppression rate%
Phosphite hydrochloride ephedrine (33) 0%
Loxoprofen sodium (10) 21%
38% of sodium hydrochloride ephedrine (33) + sodium loxofurofen (10)
By adding pseudoephedrine hydrochloride to loxoprofen sodium, the sneezing suppression effect was enhanced.
[0029]
Table 6 shows the results of the sneezing inhibitory rate of pseudoephedrine hydrochloride or ibuprofen alone or in combination.
[0030]
[Table 6]
Test substance (mg / Kg) Sneezing suppression rate%
Phosphite hydrochloride ephedrine (33) 0%
Ifuffrofen (25) 32%
