Gerontologie Alert

Angina is a common problem in older adults. When an older adult requires an antianginal drug, the dosage may be reduced to compensate for impaired renal function or heart disease. Older patients are at increased risk for postural hypotension. Blood pressure and ability to ambulate should be monitored closely.

When the drug regimen for angina pectoris is terminated, the drug dosage is gradually reduced to prevent withdrawal reactions. Abrupt withdrawal of the calcium channel blockers may cause an increase in chest pain. This phenomenon is called rebound angina and is most likely the result of the increased flow of calcium into cells, causing the coronary arteries to spasm. The calcium channel blockers should be gradually withdrawn, rather than discontinued abruptly.
