1. Signed informed consent,

2. Patients aged >= 18 years,

3. Histologically established diagnosis of collagenous colitis (CC) defined as:

   2. Increased amount of inflammatory cells indicating chronic inflammation in the lamina propria,

4. History of non-bloody, watery diarrhoea for more than 2 weeks prior screening in patients with newly diagnosed collagenous colitis, or history of clinical relapse for more than 1 week prior screening in patients with previously established collagenous colitis,

5. A mean of >= 3 stools/day, thereof a mean of >= 1 watery stools/day, during the week prior baseline,

7. Local intestinal infection,
8. Radiation therapy towards the abdominal or pelvic region,
9. Diabetes mellitus, infection, glaucoma, tuberculosis, peptic ulcer disease, or hypertension if careful medical monitoring is not ensured,

12. Established osteoporosis with T-score < -2.5,
13. Pregnancy or lactation,
14. History of cancer in the last five years,
15. History of significant bowel resection,
16. Therapy with immunomodulators (azathioprine, 6-mercaptopurine, or methotrexate) in the last 3 months,
17. Treatment with oral, rectal, or intravenous corticosteroids including budesonide in the last month,
18. Known intolerance/hypersensitivity to study drug or drugs of similar chemical structure or pharmacological profile,
