Cette étude vise à évaluer comment une combinaison de deux médicaments, le Torsémide et la Spironolactone, se comporte dans le corps lorsqu'ils sont pris ensemble sous forme de comprimé à dose fixe. Elle se concentre spécifiquement sur la compréhension de l'absorption et du traitement de ces médicaments sur plusieurs doses chez des adultes en bonne santé. La recherche est importante car elle aide à déterminer si cette combinaison est constamment efficace et sûre, ce qui pourrait potentiellement offrir une option de traitement plus pratique pour les patients qui ont besoin des deux médicaments. Les participants à l'étude prendront le comprimé à libération prolongée de Torsémide et de Spironolactone, ainsi que des comprimés séparés de Torsémide et d'Aldactone (une autre forme de Spironolactone). L'étude surveille comment ces médicaments affectent le corps en mesurant les niveaux de Torsémide et certains éléments comme le sodium, le potassium et la créatinine dans les échantillons d'urine. Ces mesures aident les chercheurs à comprendre les effets des médicaments et leur fonctionnement possible à l'état stable, garantissant que le traitement est à la fois efficace et sûr dans le temps.
