Overview

Rosacea is a chronic inflammatory disease of the central facial region, which can also occur in the neck and chest regions. Microbes that play a role in rosacea are Demodex folliculorum and Helicobactor pylori. On the skin with rosacea have decreased skin barrier function. This clinical study will compare the effectiveness and safety of metronidazole 1% cream as the main therapy in rosacea patients. Participants who will become research subjects are women and men aged 18-60 years who meet the inclusion criteria. Research subjects were divided into 2 groups. The control group will use placebo cream (without the drug substance) and the comparison group will use metronidazole 1% cream.

This study is an experimental study with a double-blind randomized controlled trial (RCT) design for researchers and subjects in male and female patients aged 18-60 years who meet the inclusion criteria. This study used 1% metronidazole cream and placebo cream as a comparison. The creams will then be coded as cream A and cream B. This research will be conducted in two places, namely the Dermatology and Venereology Polyclinic, Division of Cosmetic Dermatology, Cipto Mangunkusumo Hospital (RSCM) and the Dermatology and Venereology Polyclinic, University of Indonesia Hospital (RSUI). The control group will use placebo cream (without the drug substance) and the comparison group will use metronidazole 1% cream. All participants will be evaluated twice on days 28 and days 56. Evaluation of response to therapy that will be assessed includes the degree of erythema with a Clinician Erythema Assessment Scale (CEA) score, examination of skin scrapings for demodex examination, dermoscopy examination, and TEWL (Transepidermal Water Loss) examination.

Metronidazole 1% Cream,TopDRUG

Cream that has an active ingredient in the form of metronidazole with a content of 1%. At the beginning of the study visit, anamnesis and examination of the skin status were carried out. Skin status includes examination of the degree of erythema with a Clinician Erythema Assessment Scale (CEA) score, examination of skin scrapings for demodex examination, dermoscopy examination, and TEWL (Transepidermal Water Loss) examination. Then the participants were given metronidazole 1% cream which was to be used twice a day in the morning and at night. Evaluation of the therapeutic response will be carried out on days 28 and days 56.

PlaceboDRUG

Cream that has not medicine. At the beginning of the study visit, anamnesis and examination of the skin status were carried out. Skin status includes examination of the degree of erythema with a Clinician Erythema Assessment Scale (CEA) score, examination of skin scrapings for demodex examination, dermoscopy examination, and TEWL (Transepidermal Water Loss) examination. Then the research subjects were given Placebo cream (without the drug substance) which was to be used twice a day in the morning and at night. Evaluation of the therapeutic response will be carried out on days 28 and days 56.
