Thanks for your question. Aggrenox is a combination of aspirin and long acting dypiridamole (persantine). Both of these drugs work on small particles in the blood stream called platelets which are key to forming clots. Each drug works on a different mechanism, thereby making clot formation within blood vessels less likely. Aggrenox is taken twice a day.
As of now, aggrenox is not available as a generic. It is possible to take aspirin and generic persantine as a substitute, but the persantine is not long acting and should be taken at least three times a day. You should discuss this with your doctor and if he agrees, he can advise you on the dosage of each component.
I hope this has been helpful.

May I ask Dr Cane - is there something that is as good for stroke prevention as
aggrenox? It is so expensive and my Medicare does not cover it for less than $45.00 per month and that does not continue for the whole year and I end up paying about $130.00 for 3 or 4 months of the year. ai will appreciate an answer at your earliest convenience. Thank you, Viv
