Summary
The purpose of this study is to evaluate the platelet antiaggregant effect that a chronic
treatment with ASA (150 mg) produces,comparing this effect between two formulations of ASA:
normal and the one of sustained release, in patients with stable coronary disease.
Clinical Details
Official title: Pharmacodynamic- Pharmacokinetic Trial, Comparative Double Blind, of the Chronic Administration of 150 mg of Slow Release ASA Versus 150 mg of Normal Release ASA, in the Platelet Functionalism.
Study design: Prevention, Randomized, Double-Blind, Active Control, Parallel Assignment, Pharmacokinetics/Dynamics Study
Primary outcome: To evaluate the effect of the treatment with ASA (150 mg) produces on the tromboxan/prostacyclin balance and its repercussion in the platelet aggregation,comparing this effect between two formulations
Secondary outcome: To evaluate the principal kinetic parameters of both galenic formulations of ASA.
Detailed description:
A large clinical trials have established the efficacy of the antiaggregant products in
patients with ischemic cardiopathy, stroke and intermittent claudication.
Without doubt, the acetylsalicylic acid (ASA) is the most used antiaggregant product,
nevertheless, and spite of being centenarian, it last some questions pending regarding the
most appropriate dose, mechanism of action implicated, the association with other drugs, and
the pharmaceutical form in order to improve the efficacy and the 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 of ASA.
