[Pharma-clinics. The drug of the month. Dipyridamole-acetylsalicylic acid combination (Aggrenox)].

Aggrenox, launched in Belgium by Boehringer Ingelheim, is a fixed-dose combination of extended-release dipyridamole (200 mg) and aspirin (25 mg), two antiplatelet agents with different and complementary mechanisms of action. It is recommended, twice daily, in the protection against secondary stroke and transient ischaemic attacks. The placebo-controlled European study ESPS 2 (European Stroke Prevention Study 2) demonstrated that the administration of this combination was twice as effective as either agent alone in the secondary prevention of stroke in patients with prior stroke or transient ischaemic attack.
