Methylene blue has other actions, including the inhibition of nitric oxide synthase and guanylyl cyclase, and the inhibition of the generation of oxygen free radicals. These actions may explain the beneficial effects of methylene blue in the treatment of refractory hypotension, hepatopulmonary syndrome, treatment of priapism, modulation of streptozocin-induced insulin deficiency, prevention and treatment of ifosfamide-induced encephalopathy, in the treatment of sepsis, and the reduction of the development of postsurgical peritoneal adhesions.15,16,21,25,34,44,52,59
