Problems solved by technology

If the active ingredients are in contact with each other, there are the following disadvantages: 1. Due to the influence of multi-component mixing uniformity, it is difficult to quantify each component accurately; 2. During product testing, it is difficult to determine the content of each component due to mutual interference, which affects the qualitative and quantitative analysis results; 3. . During long-term storage, due to possible chemical compatibility changes among the components, by-products are likely to be produced, reducing the effect or increasing side effects, and the product stability is not ideal.
[0004] In addition, the main reason for the quality of irbesartan and hydrochlorothiazole compound preparations is the related substance items, which often exceed the range, and for such impurities, they are basically close to the peak of the main drug in the detected liquid chromatogram, and are generally not easy to remove

Abstract

The invention relates to an oral-taking hard capsule, and in particular relates to a tablet capsule filled with an irbesartan tablet and a thiazole hydrochloride tablet. The tablet capsule comprises a capsule and tablets in the capsule, wherein the capsule contains an upper capsule body and a lower capsule body; at least one tablet taking irbesartan as an active component and at least one tablet taking thiazole hydrochloride as an active component are filled in the capsule. According to the tablet capsule filled with the irbesartan tablet and the thiazole hydrochloride tablet, various active components in the capsule are not in contact with each other, thus the tablet capsule with good stability and convenience for processing is obtained; more importantly, an irbesartan and thiazole hydrochloride compound preparation with qualified quality of related substances can be obtained without strictly controlling intermediate-related substances.
