The recommended dose is 0.142 mg/kg/minute (0.57 mg/kg total) or 0.568 mg/kg or 60 mg total dose infused over 4 minutes. Although the maximum tolerated dose has not been determined, clinical experience suggests that a total dose beyond 60 mg is not needed for any patient.
Prior to intravenous administration, dipyridamole should be diluted in at least a 1:2 ratio with 0.45% sodium chloride injection, 0.9% sodium chloride injection, or 5% dextrose injection for a total volume of approximately 20 to 50 mL. Infusion of undiluted dipyridamole injection may cause local irritation.
Myocardial perfusion assessment should be started when maximal vasodilation is reached, usually after 3 minutes, which generally occurs approximately 7 minutes from onset of infusion
