Mechanism and action
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. Femalegra: Le citrate de sildénafil inhibe la PDE5, permettant l'accumulation de GMPc dans le muscle lisse vasculaire et augmentant le débit sanguin local lors de l'excitation sexuelle.
When Singulair is preferred
