Primary Outcome Measures:
  • Distribution of tacrolimus in the skin after first and repeated application of tacrolimus ointment in adult patients with moderate to severe atopic dermatitis. [ Time Frame: Days 1, 2, 15. 18 and 21. ]

Secondary Outcome Measures:
  • Systemic pharmacokinetics of tacrolimus after first and repeated application of tacrolimus ointment in adult patients with moderate to severe atopic dermatitis. [ Time Frame: Days 1 and 14 ]

Enrollment: 14
Study Start Date: December 2000
Study Completion Date: July 2001
Primary Completion Date: July 2001 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Tacrolimus Ointment 0.1%
    Twice daily, 14 days treatment
    Other Name: Protopic 0.1%
Detailed Description:
The study was conducted on an out-patient basis, with patients self-administering the ointment twice daily at home. However, on Days 1 and 14 there was only a single application of ointment and this was applied by the Investigator or his/her designee in the clinic. An area of the affected skin was selected for skin biopsy of sufficient size for 5 biopsy samples. The biopsy samples were taken from the same lesion(s) if possible or from an adjacent lesion in the same anatomical area at all times. All areas selected for treatment were treated with tacrolimus ointment 0.1% for a period of two weeks with a follow up period of one week. Two pharmacokinetic profiles (Days 1 and 14) and five skin biopsy samples (Days 1, 2, 15, 18 and 21) were taken.
