  • Title: [Oral magnesium supplementation to patients receiving diuretics--normalization of magnesium, potassium and sodium, and potassium pumps in the skeletal muscles].
    Author: Dørup I, Skajaa K, Thybo NK.
    Journal: Ugeskr Laeger; 1994 Jul 04; 156(27):4007-10, 4013. PubMed ID: 8066894.
    Abstract:
    In 76 consecutive patients who had received diuretics for 1-17 years for arterial hypertension or congestive heart failure, muscle concentrations of magnesium, potassium, and sodium-potassium pumps were significantly reduced compared to 31 age- and sex-matched controls. Thirty-six patients with muscle magnesium and/or potassium below the control level received oral magnesium hydroxide supplement for 2-12 weeks (N = 20) or 26 weeks (N = 16). After short term (2-12 weeks) magnesium supplementation muscle parameters were increased, but far from normalized. After magnesium supplementation for 26 weeks, the muscle concentrations of magnesium, potassium and sodium-potassium pumps were normalized in most cases. Oral magnesium supplementation may restore diuretic-induced disturbances in the concentrations of magnesium, potassium and sodium-potassium pumps in skeletal muscle. A supplemental period of at least six months seems required before complete normalization can be expected.
