    • Alternate Title:
      NEW ANTIARRHYTHMIC AGENTS IN ATRIAL FIBRILLATION.
    • Subject Terms:
      MYOCARDIAL depressants; ATRIAL fibrillation treatment; CARDIOVASCULAR agents; ARRHYTHMIA; DRUGS
    • Abstract:
      La conveniencia de contar con un acervo farmacológico seguro y eficaz en el tratamiento de la fibrilación auricular ha conducido, por una parte, a una profunda depuración en el amplio grupo de fármacos antiarrítmicos, quedando solamente un número muy restringido de compuestos de comprobada y segura actividad antifibrilatoria. Por otra parte, ha conducido al descubrimiento de nuevos conceptos fisiopatológicos que señalan a su vez novedosos objetivos terapéuticos. En función de estos objetivos se han desarrollado fármacos antiarrítmicos con actividad preferencial y hasta selectiva, sobre canales iónicos propios del miocardio auricular. Entre estos nuevos antiarrítmicos se encuentran la dofetilida, la ibutilida y el compuesto AVE0118. Por otra parte, se marcan nuevas posibilidades provistas por el conocimiento de las cualidades cardioprotectoras-antiarrítmicas del sistema opioidérgico. [ABSTRACT FROM AUTHOR]
    • Abstract:
      The convenience to count with a safe and effective pharmacological wealth for atrial fibrillation treatment had conduced, in a way, to a deep depuration of the vast array of antiarrhythmic drugs, keeping only a very restricted number of compounds with a widely proved anti-atrial activity. On the other hand, it had lead to the discovery of the pathophysiological concepts that point to novel therapeutic targets. Within these objectives is that new antiarrhythmic drugs with preferential, even selective, activity on myocardial atrium ion channels had been developed. Among these new antiarrhythmics, dofetilide, and AVE0118, are taken into account. In addition, new possibilities are opened based on the knowledge of the cardioprotective-antiarrhythmic qualities of the opioidergic system. [ABSTRACT FROM AUTHOR]
