Inclusion Criteria

1. Male and female patients, between 18 and 70 years of age. 2.

Presence of arterial hypertension (SAP ≥ 160 mm Hg; DAP ≥ 95 mm Hg). 5. Receipt of any investigational agent within 90 days of starting treatment. 6. Use of rectal 5-ASAs or rectal corticosteroids within 2 weeks before the starting the study. 7. Use of anti-TNF agents or immunosuppressive drugs such as azothioprine, 6-mercaptopurine or cyclosporine A in the last 3 months. 8. Patients with ulcerative colitis of severe entity (DAI > 10 or CAI > 12), or with limited distal ulcerative proctitis, or with infectious colitis confirmed by microbiological assessment in stool. 9. Patients with severe intestinal bleeding, or with Hb < 9 g/dL. 10. Presence of significant hepatic impairment (AST, ALT > 2 ULN). 11. Presence of significant renal impairment (creatinine > 2 ULN). 12. Women who are pregnant or who are breast feeding. 13. Intestinal obstruction. 14. Presence of type 1 or type 2 diabetes. 15.
