Description

Technical Field

[0001] The present invention relates to solid preparations and has excellent palatability containing an active ingredient having an unpleasant taste. It relates to preparations.

Background Art

[0002] Saline cathartics such as magnesium oxide, magnesium hydroxide, magnesium sulfate, and magnesium carbonate suppress water absorption in the large intestine and cause the feces in the intestine to contain water and become bulky and soft, which has an effect of promoting defecation and is widely used as a laxative with few side effects. Also, since it has an antacid effect in the pharmaceutical field, it is widely used as an antacid and a gastric mucosa protecting component in oral medications such as gastrointestinal drugs, laxatives, and cold medicines.

[0003] Bisacodyl directly acts on the large intestine mucosa and is used as a laxative that promotes peristaltic movement of the intestine and promotes defecation, and is mainly widely used by oral administration (Patent Document 1). In oral administration, in order to avoid the reduction of the effect by being decomposed in the stomach or causing unnecessary irritation to the gastric mucosa, many enteric preparations in which tablets are coated so as to dissolve in the intestine are used. Also, in the case of enteric preparations, since there is a risk that bisacodyl may dissolve in the stomach, it is recommended to avoid taking gastrointestinal drugs containing an antacid component or drinking milk within 1 hour before and after taking the medicine.

[0004] While these active ingredients are widely used, it has been reported that they have specific unpleasant tastes (bitter taste, salty taste, etc.) [[ID=…]] (Patent Documents 2 and 3).

[0005] The unpleasant taste of oral dosage forms impairs the taking feeling and causes a decrease in medication compliance (Patent Document 4). In particular, powders, granules, orally disintegrating tablets, chewable tablets, plain tablets, etc. In the case of oral medications in this dosage form, there is more contact between the oral medication's ingredients and the tongue, which can lead to an unpleasant taste and discomfort when taking the medication. The deterioration will become significant.

[0006] To date, we have helped people suppress the unpleasant taste of magnesium oxide, magnesium hydroxide, and bisacodyl. Several methods have been reported. For example, the unpleasant taste of magnesium oxide and magnesium hydroxide. As a method of suppression, combining it with stevia improves the feeling of taking it, the flavor, and the aftertaste. It has been reported that an oral composition was obtained (Patent Document 5). Also, in Patent Document 2 These are basic inorganic salts such as magnesium oxide, magnesium hydroxide, and magnesium carbonate. As a method to suppress unpleasant taste, combining lactate and sucralose improves the taste and mouthfeel. It has been reported that an oral composition with improved taste and aftertaste has been obtained. In this context, a coating method containing a specific excipient has been reported as a method for masking unpleasant tastes. It has been reported (Patent Document 6). However, these methods involve specific sweeteners or specific excipients. Because its use is essential and requires a coating process, raw material costs will increase. This will extend the process time, and further consideration is needed. [Prior art documents] [Patent Documents]
