In a placebo controlled double-blind study including 10 patients with heart failure the nisoldipine/digoxin interaction was studied. Nisoldipine was shown to elevate digoxin plasma concentrations significantly by about 15% (trough levels). During chronic combination therapy with nisoldipine trough levels and plasma concentrations 4 h after the morning dose of digoxin were 1.35 +/- 0.14 and 1.92 +/- 0.16 ng ml-1 respectively, whereas they averaged to 1.16 +/- 0.14 and 1.52 +/- 0.16 ng ml-1 with digoxin and placebo (P less than 0.05; mean +/- s.e. mean). Systolic time intervals were significantly altered by nisoldipine co-administration compared with digoxin plus placebo. In certain patients the elevation of digoxin plasma levels due to nisoldipine co-administration could be of clinical relevance.
在一项纳入10例心力衰竭患者的安慰剂对照双盲研究中,对尼索地平与地高辛的相互作用进行了研究。结果显示,尼索地平可使地高辛血浆浓度显著升高约15%(谷浓度)。在与尼索地平的慢性联合治疗期间,地高辛晨服剂量后4小时的谷浓度和血浆浓度分别为1.35±0.14和1.92±0.16 ng/ml,而地高辛与安慰剂联合治疗时平均为1.16±0.14和1.52±0.16 ng/ml(P<0.05;均值±标准误均值)。与地高辛加安慰剂相比,联合使用尼索地平显著改变了收缩期时间间期。在某些患者中,联合使用尼索地平导致地高辛血浆水平升高可能具有临床意义。
