Abstract

On s'est aperçu que l'administration d'inhibiteurs de la SPLA2 entraîne une baisse du taux de cholestérol, une diminution de la formation de la plaque athéroscléreuse et une inhibition de l'anévrisme aortique chez la souris, ainsi qu'une baisse des taux de cholestérol et de triglycérides chez l'être humain. De façon intéressante, on s'est aperçu que l'administration d'inhibiteurs de la SPLA2 entraîne une baisse du taux de cholestérol même lorsque lesdits inhibiteurs ne sont administrés qu'une fois par jour. En conséquence, la présente invention concerne des procédés de traitement de la dyslipidémie, des maladies cardio-vasculaires et des affections associées aux maladies cardiovasculaires comme l'athérosclérose et le syndrome métabolique, grâce à l'administration d'au moins un inhibiteur de la SPLA2. Il est important de noter que l'administration d'inhibiteurs de la SPLA2 et de divers composés utilisés dans le cadre du traitement des maladies cardiovasculaires, comme, par exemple, les statines, entraîne une baisse plus importante des taux de LDL et de particules de LDL dans le cadre d'un effet synergique. En outre, l'administration d'inhibiteurs de la SPLA2 et de statines entraîne une baisse synergique de l'importance de la plaque. En conséquence, la présente invention concerne également des compositions comprenant au moins un inhibiteur de la SPLA2 et au moins un composé utilisé dans le traitement des maladies cardiovasculaires, comme, par exemple, les statines, ainsi que des procédés d'utilisation de ces compositions pour traiter la dyslipidémie, les maladies cardiovasculaires et les affections associées aux maladies cardiovasculaires comme l'athérosclérose et le syndrome métabolique.
