Adjunctive Treatment with Lodenafil Carbonate for Erectile Dysfunction in Outpatients with Schizophrenia and Spectrum: A Randomized, Double‐Blind, Crossover, Placebo‐Controlled Trial

These results indicate that both lodenafil and placebo were effective in the treatment of erectile dysfunction for schizophrenia. Placebo effect is very important in patients with schizophrenia and this study showed the importance of discussing sexuality and trying to treat these patients. Further studies designed to test treatments of erectile dysfunction in patients who suffer from schizophrenia are necessary.
