    • A breath actuated dry powder inhaler (1), comprising a substantially disc shaped air circulation chamber (2) for de-agglomeration of entrained powdered medicament using the energy of the inspiratory air stream. The chamber has a substantially circular or polygonal sidewall (3) extending about a central axis (4) between top (5) and bottom walls (6) of the chamber so that the height (h) of the chamber is smaller than its diameter (d). A plurality of air supply channels (7) disposed about the circumference of the chamber, which channels extend from joint or separate air inlets and which channels enter the chamber substantially tangentially to its sidewall. At least one of the supply channels extends through a powder dose supply region (8) of the inhaler. The chamber further comprises an air outlet (9) axially extending from a discharge opening (10) in the centre of the top or bottom wall of the chamber and connects to a discharge channel (12) that extends to a mouthpiece (13). The inhaler comprises at least one further air circulation chamber for de-agglomeration of entrained powdered medicament, the chambers being connected to the mouthpiece in parallel.
    • 一种呼吸致动的干粉吸入器(1),包括基本盘形的空气循环腔(2),用于使用吸气空气流的能量使夹带的粉末状药物脱附。 腔室具有围绕腔室的顶部(5)和底壁(6)之间的中心轴线(4)延伸的大致圆形或多边形的侧壁(3),使得腔室的高度(h)小于其直径( D)。 多个空气供应通道(7)围绕室的周边设置,该通道从关节或分离的空气入口延伸,并且哪些通道基本上相对于其侧壁进入腔室。 至少一个供应通道延伸穿过吸入器的粉末剂量供应区域(8)。 腔室还包括从腔室顶壁或底壁中心的排放口(10)轴向延伸的空气出口(9),并连接到延伸到接口管(13)的排放通道(12)。 吸入器包括至少一个另外的空气循环室,用于夹带的粉末药物的去附聚,这些腔室平行连接到接口管。

    • The invention relates to an Oral Delayed Immediate Release formulation comprising a compressed core containing one or more active substances surrounded with a coating, wherein release of active substance from the core is caused by rupture of the coating after a definite lag-time, said core comprising one or more immediate release carriers and having no substantial swelling properties upon exposure to gastrointestinal fluids. The invention further relates to formulations containing an Immediate Release formulation combined with one or more Oral Delayed Immediate Release formulations with different lag-times and to a method of preparing an Oral Delayed Immediate Release formulation. The Oral Delayed Immediate Release formulation may be used for the application of active substances whenever a certain lag-time before release is advantageous, such as in the case of anti-asthmatics, anti-emetics, cardiotonics, vasodilators, anti-vertigo and anti-ménière compounds, anti-hypertensives, sedatives, anti-depressants, anti-anxiety compounds, cortico-steroids, general anti-inflammatory compounds, anti-inflammatory compounds for gastrointestinal use, anti-ulceratives, analgetics, anti-aritmics, anti-rheumatics, anti-arthritic compounds and anti-angina compounds. The Oral Delayed Immediate Release formulation may also be used for the application of biological active compounds such as proteins, peptides, enzymes, vaccines and oligonucleotides.
    • 本发明涉及一种口服延迟的立即释放制剂,其包含含有被涂层包围的一种或多种活性物质的压缩核心,其中活性物质从核心中释放是由确定滞后时间之后的涂层破裂引起的,所述核心包含 一种或多种立即释放载体,并且在暴露于胃肠液体时没有显着的溶胀特性。 本发明还涉及含有立即释放制剂与一种或多种具有不同滞后时间的口服延迟立即释放制剂组合的制剂以及制备口服延迟立即释放制剂的方法。 口服延迟即时释放制剂可以用于活性物质的应用,每当释放前的某个滞后时间是有利的,例如在抗哮喘,抗排毒,强心剂,血管扩张剂,抗眩晕和抗眩晕药物的情况下, 化合物,抗高血压药,镇静剂,抗抑郁药,抗焦虑药,皮质类固醇,一般抗炎化合物,消化道用抗炎化合物,抗溃疡药,止痛剂,抗神经药,抗风湿药, 抗关节炎化合物和抗心绞痛化合物。 口服延迟即时释放制剂也可用于生物活性化合物如蛋白质,肽,酶,疫苗和寡核​​苷酸的应用。
