Is it true that for dipyridamole stress test approx 0.57 mg/kg is used? if so why is my dose 100mg x 3 a day for antiplatelet therapy? surely i'll be living a permenant cardiac stress test? thank you for your advice?

I think I answered your question previously. IV bolus dose is completely different from oral dose. By PDR: intravenous dipyridamole appears to moderately decrease blood pressure and increase heart rate and cardiac output in response to the vasodilatory action of the drug. Oral administration does not produce these hemodynamic effects, perhaps due to its poor oral bioavailability.
