The potassium-sparing diuretic, amiloride, reduced the fractional excretion of magnesium in anaesthetized rats. Alterations in glomerular filtration rate (GFR), the filtered load of magnesium, arterial blood pressure, the status of the extracellular fluid volume, plasma aldosterone concentration and acid-base balance were not involved. It was concluded that amiloride exerted a magnesium-sparing effect by a direct renal action.
保钾利尿剂阿米洛利可降低麻醉大鼠的镁排泄分数。肾小球滤过率(GFR)、镁滤过量、动脉血压、细胞外液量状态、血浆醛固酮浓度及酸碱平衡均未发生改变。得出的结论是,阿米洛利通过直接的肾脏作用发挥保镁效应。
