|Title:||Maintenance of platelet inhibition during antiplatelet therapy|
|Abstract:||A method for reducing or maintaining platelet inhibition in a patient by administering cangrelor prior to an invasive procedure is described.

The method can further be used in patients who were previously treated with long-acting platelet inhibitors without increasing the risk of excessive bleeding.|

|Filing Date:||May 05, 2014|
|Claims:||1. A method of maintaining P2Y.sub.12 inhibition in a patient being treated with an oral P2Y.sub.12 inhibitor who is in need of surgery, the method comprising: (a) discontinuing the treatment with the oral P2Y.sub.12 inhibitor; (b) administering intravenously a 0.75 .mu.g/kg/min continuous infusion of cangrelor; and (c) discontinuing the administration of cangrelor at least about one hour prior to administration of anesthesia for the surgery. |

3. The method of claim 1, wherein the patient has a stent.
4. The method of claim 1, wherein cangrelor is administered as quickly as possible following the discontinuation of treatment with the oral P2Y.sub.12 inhibitor.
5. The method of claim 1, wherein the oral P2Y.sub.12 inhibitor is a thienopyridine.
6. The method of claim 5, wherein cangrelor is administered within about 5 days of the discontinuation of treatment with the thienopyridine.
