  Purpose

The purpose of this study is to compare urticaria lesions (size, kinetics) by thermography, volumetry and digital time lapse photography in CU patients treated with desloratadine 5 mg or desloratadine 20 mg. Hypothesis: Updosing of desloratadine (20mg) is more efficient in the treatment of urticarial lesions as compared to standard dosing (5 mg desloratadine).

  4. Age between 18 and 60 years.
  5. Female patients must be using adequate contraceptive precautions (highly effective method), or they must be postmenopausal, surgically sterilised, or hysterectomised (for details please see protocol).
  6. Female patients must be using adequate contraceptive precautions (contraceptive pill, depot, double barrier methods), or they must be postmenopausal, surgically sterilised, or hysterectomised.
  7. Voluntarily signed written informed consent.

Exclusion Criteria:

  3. History or presence of epilepsy, significant neurological disorders, cerebrovascular attacks or ischemia.
  4. History or presence of myocardial infarction or cardiac arrhythmia which requires drug therapy.
  5. Evidence of severe renal dysfunction
  6. Evidence of significant hepatic disease (liver enzymes twice the upper reference value).
  7. The presence of galactose intolerance, lapp lactase deficiency or glucose galactose malabsorption.
  8. History of adverse reactions including hypersensitivity to DL and Loratadine.
  9. Intake of medicaments that could cause QT changes (drugs listed on www.qtdrugs.org).
  10. Presence of active cancer which requires chemotherapy or radiation therapy.
  11. Presence of acute urticaria / angioedema including laryngeal edema
  12. History or presence of alcohol abuse or drug addiction.
  13. Participation in any clinical trial within 4 weeks prior to enrolment.
  14. Intake of oral corticosteroids or other immunosuppressive therapy within 14 days prior to the beginning of the study.
