Mechanism and action
Desyrel: La trazodone est classée parmi les antagonistes des récepteurs de la sérotonine et inhibiteurs de sa recapture (SARI). Singulair: Le montélukast bloque sélectivement le récepteur CysLT1, qui médie l'action des leucotriènes C4, D4 et E4 — médiateurs pro-inflammatoires libérés par les mastocytes et les éosinophiles.
