Primary Outcome Measures:
  • Evidence that lodenafil carbonate improves erectile function in patients with diabetes type 2. [ Time Frame: 16 mounths ]
    Efficacy is assessing by files of patients including questionnaires like IIEF, SEP and EHS.

Secondary Outcome Measures:
  • Adverse events in type 2 diabetes patients taking lodenafil carbonate and laboratory tests changes after this treatment. [ Time Frame: 16 months ]

    Investigator will interview patients to fill adverse events reports.

    Laboratory tests results before and after lodenafil carbonate treatment will be analyzed and compared, in order to detect significant changes.
