abstract：BACKGROUND AND PURPOSE:Sildenafil is a selective inhibitor of cGMP-specific phosphodiesterase. Sildenafil, acting via NO-dependent mechanisms, prevents indomethacin-induced gastropathy. Activation of ATP-sensitive potassium channels (K(ATP)) is involved in gastric defence. Our objective was to evaluate the role of the ...
