A
Feedback:
Older adults receiving digitalis preparations are at increased risk for toxicity because of the decreased ability of the kidneys to excrete the drug due to age-related changes. The margin between a therapeutic and toxic effect of digitalis preparations is narrow. Using digitalis preparations does not increase the risk of cardiac arrests, hyperthyroidism, or asthma.
