Primary Outcome Measures:
  • The evaluation of the effect of treatment with slow release ASA on the tromboxane/prostacyclin balance and its repercusion in the platelet aggregation [ Time Frame: one year ]

Secondary Outcome Measures:
  • Safety profile of the two different formulations of ASA (Slow Release and Normal Release) [ Time Frame: one year ]

Enrollment: 100
Study Start Date: February 2005
Study Completion Date: February 2007
Detailed Description:
  • A large clinical trials have established the efficacy of the antiaggregant products in patients with ischemic cardiopathy, stroke and intermittent claudication.
  • The acetylsalicylic acid (ASA) is the most used antiaggregant substance, nevertheless, and spite of being centenarian, it last some questions pending regarding the most appropriate dose, mechanisms of action implicated, the association with oder drugs, and the pharmaceutical fom in order to improve the efficacy and safety of the ASA.
  • Some previous studies indicate that the slow release form of ASA has a different behaviour in the platelet effect in comparison with plain formulation.
  • The aim of this study is to demonstrate the best antiaggregant and safety profile of a low dose of a slow release formulation in a long term treatment period of one year.
