Abstract:
A female patient in the sixth decade of life developed renal failure secondary to gastrointestinal bleeding, which was non-responsive to conventional therapy. She was treated with terlipressin iv; showing improvement but developing, over the next few days, ischemia and necrosis of the toes in the lower extremities, simulating necrotizing vasculitis, without response to regular management. An alternative therapy, oral sildenafil 50mg BID, was used, with a rapid reversal of the clinical picture. The vasodilator action of sildenafil is useful in cases of ischemia induced by some drugs. The objective this report is to warm about the utility of sildenafil in some potentially severe cases, like the one above.

Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
