[EN] The present invention relates to a tablet comprising at least a first and second active, the first active being in the form of a non-aqueous granulate, the second active ingredient being in the form of melt extrudated granules or a granulate (aqueous or non-aqueous). The first and second active forms are blended together. The present invention is further directed to a method of producing said tablet. [FR] La présente invention porte sur un comprimé comportant au moins un premier et un second ingrédient actif, le premier ingrédient actif étant sous la forme d'un granulat non aqueux, le second ingrédient actif étant sous la forme de granulés extrudés à l'état fondu ou d'un granulat (aqueux ou non aqueux). Les premier et second ingrédients actifs sont mélangés ensemble. La présente invention porte également sur un procédé de fabrication dudit comprimé.

60–100 kJ mol−1 for decomposition, which indicates that thermal decomposition requires high energy consumption. Under long thermal stability condition they were stable up to 50 °C; however, they were totally decomposed after 24 h at 100 °C. At 20–40 °C they can take days (t1/2 = 18–72 days) to years (t1/2 = 13–35 years) to be decomposed. On the other hand, oxidativedecomposition in water with or without
药品经常被排放到环境中,随后在饮用水,植物和土壤中被检测到。因此,这些化合物的分解或生物可降解性一直是关注的焦点。这项工作的目的是显示药物离子液体(IL-API)通过热和氧化方法的分解。研究了存在和不存在H 2 O 2以及UV-C辐射下的长期和短期热分解和氧化过程,用于四种布洛芬衍生的IL-API。短期热稳定性实验的结果表明,IL-API在高达160–200°C的温度下具有热稳定性,并且活化能为60–100 kJ mol -1分解,表明热分解需要高能量消耗。在长期的热稳定性条件下,它们在高达50°C的温度下仍稳定;但是,它们在100°C下放置24 h后会完全分解。在20–40°C下,它们可能需要几天(t 1/2 = 18–72天)到数年(t 1/2 = 13–35年)才能分解。另一方面,在有或没有H 2 O 2的水中(分别为4–12分钟和2–5小时),其氧化分解速度更快,导致IL-AP
