Dosage and administration
Rapiscan (400 mcg regadenoson solution, 5ml) is injected intravenously with no dose adjustment for body weight.
- Rapiscan should be administered over a full 10 seconds into a peripheral vein using a 22 gauge or larger catheter or needle
- The injection of Rapiscan should be followed immediately by a saline flush (5 ml of sodium chloride 9 mg/ml [0.9%] solution for injection) also administered over 10 seconds
- The radiopharmaceutical for MPI should be administered 10–20 seconds after the saline flush and may be injected directly into the same catheter as Rapiscan (see figure).
