Background summary
Rosacea is a common and chronic dermatosis, mostly occurring in middle aged, fair-skinned men and woman, affecting up to 10% of the general population. Rosacea requires long-term treatment. According to the 2005 Cochrane review, accurate randomized controlled trials (RCT’s) for the treatment of rosacea are lacking. More evidence is needed on systemic treatments that are widely used, including all tetracyclines. Recently, different doses of doxycycline have been studied. Its efficacy has been approved by several studies. And therefore the anti-inflammatory dose of doxycycline 40 mg has officially been accepted as treatment of papulopustualr rosacea. Minocycline, has been used for decades by many patients but no studies to support its effectiveness are available.
Study objective
We hypothesize that doxycycline and minocycline will be equally effective for the treatment of papulopustular rosacea.
Study design
Patients will be seen at screening and at 0, 4,m8 and 16 weeks. The follow up wil be 12 weeks (last visit at week 28).
Intervention
1. Doxycycline 40 mg;
2. Minocycline 100 mg.
These will be given during a period of 16 weeks.
