Lasix: Lasix agit au niveau de l'anse de Henle, où il bloque le cotransporteur NKCC2 qui réabsorbe normalement le sodium, le chlore et le potassium depuis l'urine vers la circulation sanguine. Crestor: La rosuvastatine inhibe de façon compétitive l'HMG-CoA réductase, enzyme limitante de la synthèse hépatique du cholestérol.
When Lasix is preferred
