Abstract
Description
本発明は、ロキソプロフェン又はその薬理上許容される塩を含有する内服液剤に関する。 The present invention relates to an internal liquid preparation containing loxoprofen or a pharmacologically acceptable salt thereof.
ロキソプロフェンは優れた解熱鎮痛作用を有する化合物であり、既に錠剤または細粒剤が上市されている。また、服用の容易性からロキソプロフェン含有液剤の提供が望まれているが、不快味を有するという問題がある。
これまでに、ロキソプロフェンと甘味剤とシクロデキストリンを含有するシロップ製剤が特許文献で報告されている（特許文献１）。また、ロキソプロフェンを起因とする胃粘膜障害を軽減したシロップ剤が知られているが、服用性に関する記載はない（特許文献２、３）。
Loxoprofen is a compound having an excellent antipyretic analgesic effect, and tablets or fine granules have already been marketed. Moreover, although provision of a loxoprofen containing liquid agent is desired from the ease of taking, there exists a problem that it has an unpleasant taste.
So far, a syrup preparation containing loxoprofen, a sweetener and cyclodextrin has been reported in Patent Literature (Patent Literature 1). Moreover, although the syrup agent which reduced the gastric mucosal disorder resulting from a loxoprofen is known, there is no description regarding ingestibility (patent document 2, 3).
本発明は、不快味を抑制したロキソプロフェン含有内服液剤及びロキソプロフェンを含有する内服液剤の不快味抑制方法を提供することにある。 It is an object of the present invention to provide a loxoprofen-containing internal liquid that suppresses unpleasant taste and a method for suppressing the unpleasant taste of an internal liquid that contains loxoprofen.
本発明者らは、上記課題を解決するために鋭意検討を重ねた結果、ロキソプロフェン又はその薬理上許容される塩を含有する内服液剤に、リジンまたはアルギニンを配合することによりロキソプロフェン含有内服液剤の不快味を抑えられることを見出し、本発明を完成するに至った。 As a result of intensive studies in order to solve the above-mentioned problems, the present inventors have found that an oral solution containing loxoprofen or a pharmacologically acceptable salt thereof is mixed with lysine or arginine to discomfort the loxoprofen-containing oral solution. The inventors found that the taste can be suppressed and have completed the present invention.
即ち本発明は、
（１）ａ）ロキソプロフェン又はその薬理上許容される塩、及びｂ）リジンまたはアルギニンを含有することを特徴とする内服液剤、
（２）ロキソプロフェン又はその薬理上許容される塩が、ロキソプロフェンのナトリウム塩である（１）に記載の内服液剤、
（３）ｐＨが2.5〜7.0である（１）〜（２）のいずれかに記載の内服液剤、
（４）ロキソプロフェン又はその薬理上許容される塩を含有する内服液剤に対して、リジンまたはアルギニンを配合することを特徴とする、ロキソプロフェン又はその薬理上許容される塩の不快味を抑制する方法、
である。
That is, the present invention
(1) a) Loxoprofen or a pharmacologically acceptable salt thereof, and b) an oral solution characterized by containing lysine or arginine,
(2) The internal use liquid preparation according to (1), wherein loxoprofen or a pharmacologically acceptable salt thereof is a sodium salt of loxoprofen,
(3) The internal liquid preparation according to any one of (1) to (2), wherein the pH is 2.5 to 7.0,
(4) A method for suppressing the unpleasant taste of loxoprofen or a pharmacologically acceptable salt thereof, characterized in that lysine or arginine is added to an oral solution containing loxoprofen or a pharmacologically acceptable salt thereof,
It is.
本発明により、ロキソプロフェン又はその薬理上許容される塩の不快味を抑制することができる。 According to the present invention, the unpleasant taste of loxoprofen or a pharmacologically acceptable salt thereof can be suppressed.

In the present invention, lysine and arginine are a kind of basic α-amino acids, which may be free or salts. Salts of lysine and arginine include salts with acids (eg, hydrochloric acid, sulfuric acid, methanesulfonic acid), bases (eg, ammonia, sodium, potassium, calcium, magnesium) or other amino acids. A representative salt is hydrochloride, but this is an example, and the present invention is not limited to hydrochloride.
In the internal use liquid preparation of the present invention, the mixing ratio of loxoprofen or a pharmacologically acceptable salt thereof and a basic amino acid is usually 0.01 to 500 parts by mass with respect to 1 part by mass of loxoprofen or a pharmacologically acceptable salt thereof, preferably Is 0.03 to 133 parts by mass, more preferably 0.06 to 16.7 parts by mass, and most preferably 0.1 to 2.7 parts by mass.

Then, purified water was added to make a total volume of 30 mL, filled into a glass bottle and capped to obtain an internal solution. Examples 15-18 and Comparative Example 5 were prepared by dissolving loxoprofen sodium, potassium chloride, tartaric acid, and L-lysine hydrochloride or L-arginine in purified water, adjusting the pH with hydrochloric acid and sodium hydroxide, Purified water was added to make up a total volume of 10 mL, filled into a glass bottle and capped to obtain an internal solution. In Examples 19 and 20, loxoprofen sodium, potassium chloride, tartaric acid, sugar and L-lysine hydrochloride or L-arginine were dissolved in purified water and prepared in the same manner as in Examples 1-8. Comparative Example 6 was prepared in the same manner as in Examples 1 to 8, except that L-isoleucine was used instead of L-lysine hydrochloride and L-arginine. Comparative Example 7 was prepared in the same manner as in Examples 1 to 8, except that sugar was dissolved in place of L-lysine hydrochloride and L-arginine.
試験方法
25〜40歳までの4人をパネルとして、試験液約20ｍＬを服用し、調製直後のロキソ
プロフェンの不快味について評価した。なお、一つのサンプルを評価した後は、温湯
で口中をすすぎ、十分経過してから次の試験液の評価を行った。
評価基準
実施例１〜８、１９、２０、比較例６、７の評価は比較例１との相対評価を行い、実施例９および１０は比較例２、実施例１１および１２は比較例３、実施例１３および１４は比較例４、実施例１５〜１８は比較例５との相対評価を行った。
実施例１〜８、比較例６は，比較例1に比べて「非常に弱く不快味を感じる」を−３点、「弱く不快味を感じる」を−２点、「やや弱く不快味を感じる」を−１点、「同等に不快味を感じる」を０点、「やや強く不快味を感じる」を1点、「強く不快味を感じる」を２点、「非常に強く不快味を感じる」を３点とし、結果を平均値で求めた。実施例９〜１８はそれぞれの比較例の評価点を０点とし、比較例に比べ「非常に弱く不快味を感じる」を−３点、「弱く不快味を感じる」を−２点、「やや弱く不快味を感じる」を−１点、「同等に不快味を感じる」を０点、「やや強く不快味を感じる」を1点、「強く不快味を感じる」を２点、「非常に強く不快味を感じる」を３点とし、結果を平均値で求めた、表４〜６に評価点として示した。
Test method
Four persons from 25 to 40 years old took a panel and took about 20 mL of the test solution to evaluate the unpleasant taste of loxoprofen immediately after preparation. After evaluating one sample, the mouth was rinsed with warm water, and the next test solution was evaluated after sufficient time had passed.
Evaluation criteria Examples 1 to 8, 19, 20 and Comparative Examples 6 and 7 were evaluated relative to Comparative Example 1, Examples 9 and 10 were Comparative Example 2, Examples 11 and 12 were Comparative Example 3, Examples 13 and 14 were compared with Comparative Example 4, and Examples 15 to 18 were compared with Comparative Example 5.
In Examples 1 to 8 and Comparative Example 6, “very weak and unpleasant taste” is −3 points, “weak and unpleasant taste” is −2 points, “slightly unpleasant taste is felt” -1 points, "Equally unpleasant taste" 0 points, "Slightly unpleasant taste" 1 point, "Strongly unpleasant taste" 2 points, "Very strongly unpleasant taste" Was obtained as an average value. In Examples 9 to 18, the evaluation score of each comparative example is set to 0, compared to the comparative example, “very weak and unpleasant taste” is −3 points, “weak and unpleasant taste” is −2 points, “slightly -1 points for "Weak and unpleasant taste", 0 points for "Equally unpleasant taste", 1 point for "Slightly unpleasant taste", 2 points for "Strongly unpleasant taste", "Very strong “I feel an unpleasant taste” was given 3 points, and the results were obtained as average values. The results are shown in Tables 4-6.
表４〜６から明らかなように、実施例は、ロキソプロフェンナトリウムと配合した際に生じる不快味が抑えられた。一方で、L-イソロイシンを配合した比較例６では不快味を改善する効果は得られなかった。また、砂糖を配合しても不快味を改善する効果は得られなかった。 As is clear from Tables 4 to 6, in the examples, the unpleasant taste produced when blended with loxoprofen sodium was suppressed. On the other hand, in Comparative Example 6 containing L-isoleucine, the effect of improving the unpleasant taste was not obtained. Moreover, even if it mix | blended sugar, the effect which improves an unpleasant taste was not acquired.
本発明は、服用性良好なロキソプロフェン又はその薬理上許容される塩を含有した内服液剤の製造に利用可能である。 INDUSTRIAL APPLICABILITY The present invention can be used for the production of an internal liquid preparation containing loxoprofen or a pharmacologically acceptable salt thereof having good dosing properties.
