Other Comments

Severe cardiovascular and cerebrovascular events have occurred during intravenous administration of dipyridamole. When used for myocardial imaging, dipyridamole should be used with caution in patients with unstable angina or in patients with bronchospastic disease. Intravenous aminophylline should be readily available to reverse the effects of dipyridamole.
