Brief Summary:
Melasma is an acquired discoloration of the skin characterized by brown colour changes commonly on the face.The duration of this double-blind clinical trial will be 12 weeks. The control group will receive treatment with topical Hydroquinone (4%), and the other group topical miconazole. Miconazol has antimelanotic properties and can be used as treatment for melasma patients. The estimated number of subjects to be recruited and randomized for the study is at least 30. The purpose of this study is determine if there is a difference in the effectiveness of these two agents. Melasma Area and Severity Index (MASI) score will be assessed at the beginning of the study and at weeks 4, 8, and 12. Photographs, colorimetry and histological assessment will be also evaluated. Occurrence of adverse effects will also be recorded.
Detailed Description:
Melasma is a common acquired hypermelanosis in dark skin populations, usually characterized by symmetrical, irregular macules occurring in photo-exposed areas such as face. Treatment with depigmenting compounds such as hydroquinone, are still the gold standard in this condition. Miconazol has depigmented properties that could be used as part of the treatment in melasma patients. This effect is exerted by inhibiting the tyrosinase enzyme. So, the primary objective of this study is to compare the depigmenting activity of miconazole against hydroquinone.
Patients who are included in the study will be randomly assigned to receive one of the treatments, which should use for 12 weeks. The medications should be applied in the affected regions twice a day.
The evaluation of clinical improvement will be done in a blinded modality by means of the MASI score, the Global Physician Assessment, as well as colorimetry and histological melanin content. Evaluations will be held on visits at 4, 8 and 12 weeks. Skin biopsy will be taken at onset and at 12 weeks.
At the end of the study, data will be compared concerning the former parameters. All side effects will be recorded and analysed.
