3 Hour Window

When symptoms of stroke occur, there is a 3 hour window of opportunity to give a drug called Activase, or t-PA. The goal of t-PA is to dissolve the clot that is causing the stroke symptoms. In some cases, after administration, there is improvement or resolution of the symptoms. There is significant risk involved with t-PA and strict guidelines for administration must be followed. For this reason, many people may be excluded from receiving t-PA.

Other treatments include aspirin, antiplatelet agents such as Plavix (clopidogrel bisulfate) or Aggrenox (aspirin and dipyridamole) or, in some cases, anticoagulants such as Coumadin (Warfarin).
