很明显,同时服用AR可增强PcA的降低血压,心率和肾素-血管紧张素系统活性的作用。这种作法可在麻醉或清醒的大鼠、狗、猫、猴或微型锗的标准试验(如EP-A2-0,27,271描述的方法)中发现。
这种新的药物组合物可通过将(至少)一种PccA和(至少)一种AR一起与至少一种固体、液体或半液体载体或辅助剂制成合适的剂型来制备。该组合物既可人用也可兽用,尤其是用于降低血压。合适的载体是适用于肠道(如口服或肛用)、非肠道或局部用药的有机或无机物质,而且不与水、植物油、苄醇、聚乙二醇、三乙酸甘油酯以及其他脂肪酸甘油酯、明胶、大豆磷脂、乳糖或淀粉等碳水化合物、硬脂酸镁、滑石或纤维素等反应。口服的有片剂、糖衣片、胶囊、糖浆、溶液或滴液;肛用的有栓剂;非肠道用的有溶液,特别是油状或水状溶液,还有悬浮液,乳液或移植物;局部用药的有软膏,乳剂或硬膏。有效成份可制成冻干剂用于制备注射液。该组合物可被消毒灭菌和/或含有辅助剂如防腐剂、稳定剂和/或湿剂、乳化剂、影响渗透压的盐类、缓冲剂、着色剂和/或调味剂。也可包含其他活性物质,如其他降压药或利尿剂。
按照本发明,该组合物一般用于治疗或预防心血管系统疾病,特别是失代偿性心力衰竭、心绞痛、外周或脑血管疾病和与高血压有关的病理状态,其作用与已知和降压药特别是AR本身相似。PcA用药剂量的每一剂量单位为0.01mg至50mg,特别是以0.02至5mg为宜,而以0.1至1mg最为合适。AR用药剂量的每一剂量单位在0.5和500mg之间,而以1至100mg为单位剂量最合适。PcA的每日用药在0.0001至1mg之间,以0.0002至0.1mg/kg体重最合适,AR的最适量为0.01至10mg/kg体重。但对每一具体病人的具体用药时取决于诸多因素,如所用具体化合物的活性,年龄、体重、机体的一般状态、性别、进食量、用药的时间和途径、药物消失率、联合用药和所治疗的具体疾病的严重程度。优选口服用药。
这种新的药物组合物的成份更适于联合用药,但是它们也可单独、同时或错开用。
实例A:片剂
20gPcA活性成份(如Ia),0.4kg  AR活性成份(如DuP753),4g乳糖、1.2g土豆淀粉、0.2kg滑石和0.1kg硬脂酸镁的混合物用常规方法压成片,每片中含1mgPcA活性成份和20mgAR活性成份。
