The comparative cardiovascular effects of digoxin and food alone and in combination in normal males.

Abstract:

:The effects of the ingestion of food and digoxin on the cardiovascular system alone and in combination have been observed in eight healthy subjects. A positive inotropic response was seen following food (2.5 MJ) and intravenous digoxin (0.01 mg/kg) with significant decreases in QS2Index (QS2I) pre-ejection period (PEP) and PEP/LVET (LVET - left ventricular ejection time). These responses were potentiated when food and digoxin were combined. Opposing effects of food and digoxin on % diastole (%D) and diastolic time were observed, food decreasing %D and DT while digoxin increased these variables. Both food and digoxin decreased T-wave amplitude, and digoxin alone or in combination with food decreased QTc. The positive inotropic effect of a 2.5 MJ mixed meal and a loading dose of digoxin in healthy subjects are of similar degree, different mechanism, and are potentiated in combination.
