title: [Digitoxin blood picture and renal elimination in long-term therapy with aluminum-magnesium hydroxide gel].
abstract: In ten patients in heart failure for which they were on long-term administration of digitoxin, the influence of aluminium-magnesium hydroxide gel (Maaloxan) on steady-state digitoxin plasma concentration and renal glycoside excretion was studied. Compared with control values before antacid medication (13.6 +/- 4.4 ng/ml), the administration of 20 ml aluminium-magnesium hydroxide gel three or four times daily for several weeks caused no significant change in digitoxin plasma levels (15.1 +/- 4.9 ng/ml). Daily renal glycoside excretion, as a further measure of bioavailability of digitoxin, was also unchanged by the antacid. Therapeutic plasma concentrations of digitoxin are not influenced by antacids which contain aluminium-magnesium hydroxide, at least not if the antacid is taken 1-2 hours after the digitoxin dose.
