Description

本発明は、有効成分としてレボセチリジンまたはその薬学的に許容される塩を含有する固形製剤に関する。  The present invention relates to a solid preparation containing levocetirizine or a pharmaceutically acceptable salt thereof as an active ingredient.

レボセチリジン塩酸塩(Levocetirizine Hydrochloride)は、アレルギー性鼻炎、蕁麻疹等に対する治療薬として知られ、錠剤とシロップ剤が販売されている(非特許文献1参照)。  Levocetirizine hydrochloride (Levocetirizine Hydrochloride) is known as a therapeutic agent for allergic rhinitis, urticaria, etc., and tablets and syrups are marketed (see Non-Patent Document 1).

ザイザル(登録商標)錠5mg、ザイザル(登録商標)シロップ0.05%の医薬品インタビューフォーム(2017年3月改訂(第9版))Pharmaceutical interview form with 5 mg of Zyzar (registered trademark) tablets and 0.05% of Zysar (registered trademark) syrup (revised March 2017 (9th edition))

しかしながら、一般に錠剤は、小児や高齢者には嚥下しにくく服用性に劣る。一方、シロップ剤は、液状であり小児や高齢者であっても服用しやすいが、冷所に保管する必要がある場合が多く、携帯もしにくい等、取扱性に劣る。これに対して顆粒製剤は、嚥下性に優れ、一般に冷所に保管する必要がなく、携帯もしやすい。また、口腔内速崩壊錠も、嚥下性に優れ、取扱性にも優れる。よって、レボセチリジンまたはその薬学的に許容される塩を含有する製剤においても、顆粒製剤や口腔内速崩壊錠が求められる。
また、固形製剤には、保存時の安定性に優れることが当然に要求される。
However, tablets are generally difficult to swallow for children and the elderly and inferior to the patient. On the other hand, syrups are liquid and easy to take even for children and the elderly, but they often need to be stored in a cold place and are not easy to carry. On the other hand, the granule preparation is excellent in swallowability and generally does not need to be stored in a cold place and is easy to carry. Moreover, the intraoral quick disintegrating tablet is also excellent in swallowability and excellent in handleability. Therefore, granule preparations and intraoral quick disintegrating tablets are also required for preparations containing levocetirizine or a pharmaceutically acceptable salt thereof.
In addition, the solid preparation is naturally required to have excellent stability during storage.

本発明は、上記事情に鑑みてなされたもので、レボセチリジンまたはその薬学的に許容される塩を含有する固形製剤(以下、レボセチリジン固形製剤ともいう。)の提供、特に、経時的な類縁物質の増加が抑制され安定性に優れた固形製剤の提供を目的とする。  The present invention has been made in view of the above circumstances, and provides a solid preparation containing levocetirizine or a pharmaceutically acceptable salt thereof (hereinafter also referred to as levocetirizine solid preparation), in particular, a related substance over time. An object of the present invention is to provide a solid preparation with suppressed increase and excellent stability.

本発明者が、レボセチリジンまたはその薬学的に許容される塩を含有する顆粒製剤や口腔内速崩壊錠等の開発を進めていく過程で、レボセチリジン固形製剤にリンゴ酸塩を配合することにより、経時的な類縁物質の増加を抑制でき、安定性に優れる固形製剤が得られることを見出し、本発明を完成するに至った。  In the process of developing the granule preparation or intraoral quick disintegrating tablet containing levocetirizine or a pharmaceutically acceptable salt thereof, the present inventor added malate to the levocetirizine solid preparation, The present inventors have found that a solid preparation having excellent stability can be suppressed and an excellent stability can be obtained, and the present invention has been completed.

次のようにして表1の処方のレボセチリジン固形製剤(顆粒製剤(ドライシロップ剤))を製造した。
まず、粉末還元麦芽糖水アメと、β−シクロデキストリンとをそれぞれ秤量して混合した混合物に対し、レボセチリジン二塩酸塩とリンゴ酸二ナトリウム塩・1/2水和物(「DL−リンゴ酸ナトリウム」(扶桑化学工業社製))を精製水に加えて溶解させた混合液を加え、造粒、乾燥、整粒を行い、実施例1の顆粒製剤(ドライシロップ剤)を得た。
得られた顆粒製剤について、後記の方法にて純度試験を行った。結果を表1に示す。
A levocetirizine solid preparation (granule preparation (dry syrup preparation)) having the formulation shown in Table 1 was produced as follows.
First, levocetirizine dihydrochloride and malate disodium salt ½ hydrate (“DL-sodium malate”) were prepared by weighing and mixing powdered reduced maltose water candy and β-cyclodextrin. (Fuso Chemical Co., Ltd.)) was added to the purified water and dissolved, and the mixture was granulated, dried and sized to obtain the granule preparation of Example 1 (dry syrup agent).
About the obtained granule formulation, the purity test was done by the method of the postscript. The results are shown in Table 1.

[比較例1]
表1に示すように、リンゴ酸二ナトリウム塩・1/2水和物を使用しない処方とし、その分、粉末還元麦芽糖水アメの比率を高めた以外は、実施例1と同様にして比較例1の顆粒製剤(ドライシロップ剤)を得て、実施例1と同様の方法で純度試験を行った。結果を表1に示す。
[Comparative Example 1]
As shown in Table 1, Comparative Example was made in the same manner as in Example 1 except that malic acid disodium salt 1/2 hydrate was not used and the proportion of powdered reduced maltose water candy was increased accordingly. 1 granule preparation (dry syrup preparation) was obtained, and the purity test was performed in the same manner as in Example 1. The results are shown in Table 1.

<純度試験>
実施例1及び比較例1の各顆粒製剤を表1に示す3条件で2週間保存した際の保存前後の総類縁物質量を測定することで、純度試験を実施した。
なお、総類縁物質量は、高速液体クロマトグラフィーを用いた自動分析法にて測定、定量した複数種の類縁物質量の総和であり、表1に記載の総類縁物質量の数値は、レボセチリジン二塩酸塩由来のピーク面積に対する、各類縁物質によるピーク面積の総和の割合を百分率で示したものである。
<Purity test>
The purity test was carried out by measuring the total amount of related substances before and after storage when each granule preparation of Example 1 and Comparative Example 1 was stored for 2 weeks under the three conditions shown in Table 1.
Note that the total amount of related substances is the sum of the amounts of plural kinds of related substances measured and quantified by an automatic analysis method using high performance liquid chromatography. The percentage of the sum total of the peak areas of each related substance to the peak area derived from the hydrochloride is shown as a percentage.
