Serum and mononuclear cell magnesium content were determined in a cross-sectional study performed in four groups of hypertensive patients on chronic treatment with atenolol (n = 11), enalapril (n = 10), thiazide diuretics (n = 12), or enalapril + thiazides (n = 11). Our study shows that in patients treated with the thiazides alone, in spite of normal serum potassium and magnesium levels, mononuclear cell magnesium was decreased. To the extent that mononuclear Mg content mirrors the body ion stores, our results indicate that thiazides induce a Mg depletion not detectable by monitoring serum levels.
