Permethrin 5% cream versus metronidazole 0.75% gel for the treatment of papulopustular rosacea. A randomized double-blind placebo-controlled study

BACKGROUND: Permethrin 5% cream used against human ectoparasites suggests that it may be effective in papulopustular rosacea. METHODS: This study included 63 patients diagnosed as having papulopustular rosacea based on the clinical and histological findings. Patients were randomly assigned into permethrin (n = 23), metronidazole (n = 20) and placebo (n = 20) groups. Scores of erythema, telangiectasia, edema and rhinophyma and the numbers of papules, pustules, inflammatory nodules and Demodex folliculorum were determined. Twenty-three patients were given permethrin 5% cream (Zalvor 5% skin cream, 20 patients metronidazole 0.75% gel (Roza gel and 20 patients placebo cream (Basis cream, in packages looking identical to those of metronidazole and permethrin creams, and were recommended to apply them to their faces twice a day. All patients were also given SPF 20 cream for protection against sunlight. Two months of treatment were planned, and the patients were invited to the clinic for fortnightly controls. Scores of erythema, telangiectasia, edema and rhinophyma and the numbers of papules, pustules, inflammatory nodules and D. folliculorum were recorded at each visit. The mean scores of erythema and the mean numbers of papules, pustules and D. folliculorum were determined at baseline and on days 15, 30, 45 and 60. Side effects were also detected. RESULTS: The effect of permethrin 5% cream on D. folliculorum was superior to that of metronidazole 0.75% gel. The effect of permethrin 5% cream on erythema and papules was found to be more effective than placebo and as effective as metronidazole 0.75% gel. However, it had no effect on telangiectasia, rhinophyma and pustules. CONCLUSION: It can be concluded that the application of permethrin 5% cream twice daily for 2 months can be as effective and reliable as metronidazole in the treatment of rosacea and a greater benefit can be gained when it is combined with other systemic and/or topical treatments.     

Adapalene vs. metronidazole gel for the treatment of rosacea

BACKGROUND: Rosacea is a common, chronic dermatosis that requires long-term therapy. Oral isotretinoin and topical and/or oral antibiotics are effective, but their usage may be limited due to side-effects. OBJECTIVE: The goal of the study was to compare the efficacy of topical adapalene gel (0.1%) and topical metronidazole gel (0.75%) in the treatment of patients with papulopustular rosacea. METHODS: This study included 55 patients with papulopustular rosacea. Diagnostic efforts were focused on clinical and histological features. Patients were randomly assigned to the adapalene (n = 30) and metronidazole (n = 25) groups. Sunlight protection factor 20 cream was used to protect all patients from sunlight. The characteristics and numbers of inflammatory papules, pustules, erythema and telangiectasia were scored at baseline and after 2, 4, 8 and 12 weeks. Side-effects were recorded at each visit. RESULTS: Fifty patients, 27 in the adapalene group and 25 in the metronidzaole group, completed the study. Significant reductions in the total number of inflammatory lesions were found in the adapalene group compared with the metronidazole group. There was no significant difference in the scores of erythema and telangiectasia in the adapalene group. However, a significant reduction in erythema was seen in the metronidazole group. CONCLUSIONS: Adapalene gel is well tolerated and can be used as an alternative for topical treatment of papulopustular rosacea.     

A comparison of topical azelaic acid 20% cream and topical metronidazole 0.75% cream in the treatment of patients with papulopustular rosacea

Background: Although it is important for physicians to have sufficient clinical data on which to base treatment decisions, little comparative data exist regarding newer treatment modalities for rosacea. Objective: The goal of the study was to compare the efficacy and safety of topical azelaic acid 20% cream and topical metronidazole 0.75% cream in the treatment of patients with papulopustular rosacea. Parameters of patient satisfaction to treatment were also assessed. Methods: Forty patients with the clinical manifestation of symmetric facial rosacea were investigated in this single-center, double-blind, randomized, contralateral split-face comparison clinical trial. Results: After 15 weeks of treatment, both azelaic acid and metronidazole induced significant, albeit equal reductions in the number of inflammatory lesions (pustules and papules). A significantly higher physician rating of global improvement was achieved with azelaic acid. Changes in the rosacea signs and symptoms of dryness, burning, telangiectasia, and itching were equal between treatments. A reduction in erythema tended toward significance with azelaic acid at week 15. A trace amount of stinging on application was noted with azelaic acid; however, such discomfort did not appear to concern patients because their overall impression of azelaic acid was superior to that of metronidazole. Conclusion: Azelaic acid 20% cream provides an effective and safe alternative to metro-nidazole 0.75% cream with the added benefit of increased patient satisfaction.

Topical metronidazole for rosacea

Rosacea is relatively common, typically occurring in individuals of Northern European and Celtic origin between 30 and 50 years of age. It is more common in women, but may be more severe in men. Currently there is no cure available for rosacea, but it can be controlled with topical and oral drug therapy. Topical metronidazole 1% cream is approved by the US FDA for the treatment of inflammatory lesions (papules and pustules) and erythema associated with rosacea. This treatment option is effective, safe and well tolerated.     

Randomized placebo-controlled trial of metronidazole 1% cream with sunscreen SPF 15 in treatment of rosacea

Background: Rosacea is a photoaggravated dermatosis responsive to treatment with topical and oral antibiotics. A formulation combining metronidazole 1% cream with sunscreen SPF 15 was developed for the treatment of rosacea. Objective: The objective of this study was to determine the safety and efficacy of a formulation combining metronidazole 1% cream with sunscreen SPF 15 in the treatment of moderate to severe rosacea. Methods: One hundred and twenty patients with moderate to severe rosacea were enrolled for a randomized, placebo-controlled (vehicle containing sunscreen with SPF 15), double-blind study. Study cream was applied twice daily to the entire face over a 12-week period. Results: Treatment with metronidazole 1% cream with sunscreen SPF 15 resulted in significant improvement (p <0.05) in inflammatory lesion count, erythema and telangiectasiae scores, and investigator and patient global assessment scores compared with baseline and placebo. Adverse reactions related to study medication were typically mild, occurred at the site of application, and were reversible. There was no difference between the safety profiles of metronidazole 1% cream with sunscreen SPF 15 and placebo. Conclusions: The combined topical formulation of metronidazole 1% cream with sunscreen SPF 15 was an effective, well-tolerated topical agent for the treatment of moderate to severe rosacea.     

Use of permethrin in the treatment of rosacea fulminans during pregnancy: One case report

Rosacea fulminans (RF) is a rare dermatological condition which occurs exclusively in women and it is characterized by a sudden onset of painful papules, pustules, cysts, and nodules on the face. A 28‐year‐old woman was referred to our clinic due to a painful facial eruption within the 13th week of her second pregnancy. After physical examination, the diagnosis of RF during pregnancy was established. Several treatments were used: mupirocin ointment, topical zinc oxide, topical erythromycin, oral erythromycin, metronidazole gel, oral metronidazole, oral amoxiciline, and oral prednisone. Finally, the patient was started on 5% permethrin cream with complete clearing of the lesions. Nowadays, a wide range of treatments for rosacea is available: topical metronidazole, oral metronidazole, topical ivermectin, oral tetracyclines, oral isotretinoin, systemic steroids, photodynamic therapy, or pulsed dye laser. However, in pregnant patients, the treatment alternatives are limited. We consider that 5% permethrin cream could be an effective, cheap, and safe treatment not only in regular patients with rosacea but also in pregnant women, representing an important alternative in the context of pregnancy when therapeutic options are limited. To our knowledge, this is the first case of rosacea treated with 5% permethrin cream in monotherapy during pregnancy.     

Double-blind, randomized, vehicle-controlled clinical trial of once-daily benzoyl peroxide/clindamycin topical gel in the treatment of patients with moderate to severe rosacea

BACKGROUND: Systemic antibiotics such as tetracycline are well accepted as effective in treating the inflammatory papular/pustular phase of rosacea but may be associated with systemic side-effects. Few controlled data on the use of topical antibiotics in rosacea are available. OBJECTIVE: We evaluated the efficacy and tolerability of a fixed combination of 5% benzoyl peroxide and 1% clindamycin in a topical gel for the treatment of rosacea. Methods This was a 12-week, double-blind, vehicle-controlled, randomized, prospective, parallel-group study in 53 patients with moderate to severe rosacea. RESULTS: The mean percentage reduction in papules and pustules from baseline to the end of treatment was 71.3% in the benzoyl peroxide/clindamycin group (n = 26) and 19.3% in the vehicle group (n = 26; P = 0.0056). A significant (P = 0.0141) difference in favor of benzoyl peroxide/clindamycin was evident by the third week of treatment. Severity scores for erythema, papules/pustules, and flushing/blushing decreased more with benzoyl peroxide/clindamycin than with vehicle. Overall rosacea severity, Physician Global Assessment, and Patient's Global Assessment at the end of treatment were all significantly improved with benzoyl peroxide/clindamycin compared with vehicle (P = 0.0101, 0.0026, and 0.0002, respectively). Application site reactions were reported in four patients (14.8%) in the benzoyl peroxide/clindamycin group. CONCLUSION: A once-daily topical application of a combination of 5% benzoyl peroxide and 1% clindamycin is effective and well tolerated in patients with moderate to severe rosacea.     

Comparative study of some treatment modalities of rosacea

Background   Rosacea is a disease of complex pathogenesis and variable response to various therapeutic methods.
Aim of the work   To evaluate and compare the efficacy, safety and side effects of some topical lines of treatment of rosacea.
Patients and methods   The study included 24 patients (23 females and 1 male) with rosacea on the face. They were classified into three groups – each including eight patients (16 face sides) – and treated with one of three topical agents (azelaic acid 20% cream, metronidazole 0.75% cream or permethrin 5% cream) on one side of the face and another one on the other side twice daily for 15 weeks.
Results   There was a significant improvement of lesions after 15 weeks of topical treatment with the three agents. Azelaic acid cream was significantly more effective on inflammatory lesions but not erythema than the other two creams. Side effects – mostly transient – were observed with topical creams with no significant difference. They included itching, burning sensation, oedema and scales. Patients who used azelaic acid 20% cream were more satisfied than with other modalities.
Conclusion   Azelaic acid 20% cream provides an effective and safe alternative to metronidazole 0.75% cream or permethrin 5% cream with the added benefit of increased patient satisfaction.     

A comparison of metronidazole 1% cream and pimecrolimus 1% cream in the treatment of patients with papulopustular rosacea: a randomized open‐label clinical trial

Background. There are various treatment options available for rosacea, depending on the subtype, but treatment is still generally unsatisfactory. Some reports have indicated beneficial effects of topical pimecrolimus. Aim. To compare the efficacy and safety of pimecrolimus 1% cream and metronidazole 1% cream in the treatment of patients with papulopustular rosacea (PR). Methods. A group of 49 patients with PR was investigated in this single‐centre, randomized, open‐label study. Patients were randomly assigned treatment with either pimecrolimus 1% cream or metronidazole 1% cream for 12 weeks. Response was evaluated by the inflammatory lesion count, the severity of facial erythema and telangiectasia, Physician’s Global Assessment (PGA), and safety and tolerability at baseline and at weeks 3, 6, 9 and 12. Results. In total, 48 patients completed the study. Both treatments were very effective in the treatment of PR. There were no significant differences between the treatments in inflammatory lesion counts, overall erythema severity scores and PGA evaluated from baseline to week 12 (P > 0.05). Neither treatment produced any clinically relevant improvement in telangiectasia. Conclusion. Pimecrolimus cream is no more efficacious than metronidazole cream in the treatment of PR.     

Azelaic acid in the treatment of papulopustular rosacea: a systematic review of randomized controlled trials

OBJECTIVE: To evaluate the clinical efficacy of topical 20% azelaic acid cream and 15% azelaic acid gel compared with their respective vehicles and metronidazole gel in the treatment of papulopustular rosacea. DATA SOURCES: Electronic searches of MEDLINE, EMBASE, BIOSIS, and SciSearch through July or August 2004 and the Cochrane Central Register of Controlled Trials through 2004 (issue 3). We performed hand searches of reference lists, conference proceedings, and clinical trial databases. Experts in rosacea and azelaic acid were contacted. STUDY SELECTION: Randomized controlled trials involving topical azelaic acid (cream or gel) for the treatment of rosacea compared with placebo or other topical treatments. Two authors independently examined the studies identified by the searches. Ten studies were identified, of which 5 were included (873 patients). DATA EXTRACTION: Two authors independently extracted data from the included studies, then jointly assessed methodological quality using a quality assessment scale. DATA SYNTHESIS: Because standard deviation data were not available for 4 of the 5 studies, a meta-analysis could not be conducted. Four of the 5 studies demonstrated significant decreases in mean inflammatory lesion count and erythema severity after treatment with azelaic acid compared with vehicle. None of the studies showed any significant decrease in telangiectasia severity. CONCLUSIONS: Azelaic acid in 20% cream and 15% gel formulations appears to be effective in the treatment of papulopustular rosacea, particularly in regard to decreases in mean inflammatory lesion count and erythema severity. Compared with metronidazole, azelaic acid appears to be an equally effective, if not better, treatment option.     

Pimecrolimus 1% cream for the treatment of steroid-induced rosacea: an 8-week split-face clinical trial

BACKGROUND: Steroid-induced rosacea is a relatively common dermatosis that is caused by the prolonged application of topical steroid to the face. OBJECTIVES: The purpose of this investigator-blind, split-face study was to evaluate the efficacy and safety of pimecrolimus 1% cream for the treatment of steroid-induced rosacea. PATIENTS/METHODS: Patients were instructed to apply pimecrolimus 1% cream twice daily to the involved areas of a randomly allocated half side for the first 2 weeks, and to follow this by applying pimecrolimus 1% cream to both sides for a further 6 weeks. RESULTS: Fifteen of the 18 patients completed the 8-week study. After 1 week of application, a statistically significant improvement was observed for investigator's global assessments of erythema and papules on prior-treated sides (P-side). Later-treated sides (L-side) showed subsequent improvement after use of pimecrolimus on the L-side. Likewise, a statistically significant improvement was also observed for numbers of papules/pustules on P-sides after 1 week, and L-sides showed a significant improvement after application of pimecrolimus on the L-side. Comparative reflectance colorimetric assessments revealed that DeltaL*, Deltaa* and Deltab* tended to converge to zero during the first 4 weeks. A statistically significant improvement was observed for percentage area affected on P-sides after 1 week of application. The L-side showed a significant improvement after use of pimecrolimus cream on that side. The visual analogue scale of P-sides decreased more rapidly than those of L-sides. Cutaneous side-effects were mild and transient. CONCLUSIONS: This study suggests that pimecrolimus 1% cream is an effective and well-tolerated treatment for steroid-induced rosacea.     

Rosacea Fulminans in Pregnancy

Rosacea fulminans is a rare disease of unknown cause which occurs exclusively in women years after adolescence. Although the etiology is unknown, immunologic, hormonal, and vascular factors have been suggested. When rosacea fulminans occurs during pregnancy and in women taking oral contraceptive pills, hormonal factors may be a trigger. Rosacea fulminans is localized specifically to the face, with the chin, cheeks, and forehead bearing the brunt of the attack. A dull red, cyanotic erythema of all involved facial areas, extending beyond the inflammatory nodules, is typical. We present the case of a 31-year-old pregnant woman who had rosacea fulminans during the first trimester of her second pregnancy. She had multiple erythematous papules, pustules, nodules, and purulent discharging cysts on the face. Conventional therapeutic approaches with systemic corticosteroids were associated with clear improvement within 2 months, and subsequently only 0.75% metronidazole topical cream was used during the second trimester.

Topical metronidazole in the treatment of rosacea

One percent metronidazole in an emollient cream base was compared with 250 mg oral tetracycline taken twice daily for the treatment of seventy-five patients with rosacea. After eight weeks of treatment there was no statistically significant difference between the results of the two treatments. Tetracycline did have a more rapid onset of effect on papules and pustules. Both treatments were well tolerated.     

Efficiency of benzoyl peroxide-erythromycin gel in comparison with metronidazole gel in the treatment of acne rosacea

Oral wide-spectrum antibiotics are the linchpin of rosacea treatment. Oral and topical metronidazole, topical tretinoin, and topical benzoyl peroxide may also be used in the treatment of rosacea. We aimed to show that benzoyl peroxide-erythromycin gel is efficient in the treatment of acne rosacea. Fifty-six patients with acne rosacea were enrolled in our study. We administered benzoyl peroxide-erythromycin gel to 27 patients and metronidazole gel to 29 patients. In all the patients, the intensities of erythema, telangiectasia, papules/pustules, and nodules were evaluated before, during and after the treatment. The positivity of Demodex folliculorum from skin scratches was compared between the two groups at each visit. At the end of the therapy on the third examination, in the benzoyl peroxide-erythromycin group, 91.7% of the patients showed marked clinical improvement, and 8.3% of them showed complete remission. In the metronidazole group, 73.3% showed marked clinical improvement, and 26.7% of them showed complete remission. Clinical improvement in the papular component was 65.2% for the benzoyl peroxide-erythromycin group, and 81.5% for metronidazole group. In the first examination, the clinical results of the agents were similar. Although both of the drugs were found to be effective in the second and third examinations, metronidazole gel was more effective than benzoyl peroxide-erythromycin. Both of the drugs were found to be significantly effective especially in treating the papular component of rosacea. Demodex folliculorum was found to be positive in 74.1% of the benzoyl peroxide-erythromycin group and in 62.1% of the metronidazole group at the beginning. In the benzoyl peroxide-erythromycin group, 40.7% of Demodex folliculorum positive patients, became negative by the first examination. This was 17.2% for the metronidazole group. In the benzoyl peroxide-erythromycin group, among the patients who were positive for Demodex folliculorum in the first examination, 37.5% of them became negative. This was 36.7% for the metronidazole group. Benzoyl peroxide-erythromycin gel was superior to metronidazole gel in decreasing Demodex folliculorum by the first examination, but the effect of the two drugs on Demodex folliculorum was similar by the second examination. As a result, topically applied combined benzoyl peroxide-erythromycin gel may be an alternative choice of treatment for acne rosacea.     

A comparison of 15% azelaic acid gel and 0.75% metronidazole gel in the topical treatment of papulopustular rosacea: results of a randomized trial

OBJECTIVE: To compare the efficacy and safety of a novel formulation of 15% azelaic acid gel (Finacea; Berlex Laboratories, Inc, Montville, NJ) with 0.75% metronidazole gel (MetroGel; Galderma Laboratories LP, Fort Worth, Tex) as topical therapy for moderate, papulopustular facial rosacea. DESIGN: Multicenter, double-blind, randomized, parallel-group study. SETTING: Thirteen US centers. PATIENTS: A total of 251 patients with papulopustular rosacea with persistent erythema and telangiectasia. INTERVENTIONS: Patients were randomized to receive azelaic acid gel or metronidazole gel twice daily for 15 weeks. MAIN OUTCOME MEASURES: Nominal and percent change in inflammatory lesion count, change in erythema and telangiectasia severity ratings, investigator's global assessment of rosacea, and investigator's and patient's overall improvement ratings. RESULTS: Azelaic acid gel was superior to metronidazole gel in reduction of mean nominal lesion count (-12.9 vs -10.7, respectively) (P =.003) and mean percent decrease in inflammatory lesions (-72.7% vs -55.8%, respectively) (P<.001). With respect to erythema severity, 56% of azelaic acid gel-treated patients were rated improved vs 42% of metronidazole gel-treated patients (P =.02). The effectiveness of metronidazole gel on these variables seemed to plateau after week 8, whereas azelaic acid gel demonstrated progressive improvement through week 15. Neither treatment had a clinically appreciable effect on telangiectasia. Both the investigator's global assessment (P =.02) and overall assessment of improvement (P =.005) showed a significant therapeutic advantage for azelaic acid gel. Azelaic acid gel also scored higher on the patient's overall assessment of efficacy. Both treatments were rated as having high cosmetic acceptability. No serious or systemic treatment-related adverse events were reported in either group. CONCLUSION: Use of 15% azelaic acid gel twice daily for 15 weeks demonstrated significant superiority over using 0.75% metronidazole gel in improving principal signs of rosacea (inflammatory lesions and erythema).     

Combination sodium sulfacetamide 10% and sulfur 5% cream with sunscreens versus metronidazole 0.75% cream for rosacea

Topical metronidazole and combination sodium sulfacetamide and sulfur commonly are used to treat rosacea. Recently, the relative efficacy and safety of sodium sulfacetamide 10% and sulfur 5% cream with sunscreens (Rosac Cream) (n = 75) and metronidazole 0.75% cream (Metrocream) (n = 77) were compared in an investigator-blinded, randomized, parallel-group study at 6 sites. After 12 weeks of treatment with sodium sulfacetamide 10% and sulfur 5% cream with sunscreens, there was a significantly greater percentage reduction (80%) in inflammatory lesions compared with metronidazole 0.75% cream (72%)(P = .04), as well as a significantly greater percentage of subjects with improved erythema (69% vs 45%, respectively; P = .0007). In addition, the sodium sulfacetamide 10% and sulfur 5% cream with sunscreens group had a significantly greater proportion of subjects with success in global improvement at week 12 compared with the metronidazole 0.75% cream group (79% vs 59%, respectively; P = .01). There was no significant difference between treatment groups in the percentage of subjects with improvement in investigator global severity. Overall tolerance was good or excellent in 85% of subjects in the sodium sulfacetamide 10% and sulfur 5% cream with sunscreens group and in 97% of subjects in the metronidazole 0.75% cream group. Seven subjects had poor tolerance to the sodium sulfacetamide 10% and sulfur 5% cream with sunscreens, possibly caused by a sulfa drug allergy.     

Perioral dermatitis

Perioral dermatitis is a relatively common inflammatory disorder of facial skin, often appearing in patients with rosacea, but with less inflammation. A typical perioral dermatitis presentation occurs with the eruption of papules and pustules confined to the nasolabial folds and the skin of the chin. Clinically, small pink papules and pustules may recur over weeks to months, sometimes with fine scales. The differential diagnosis includes seborrheic dermatitis, systemic lupus erythematosus, acne vulgaris, lupus miliaris disseminatus faciei, steroid-induced rosacea, and even basal cell carcinoma. The histopathology is similar to that found in rosacea. With advancement of the process, a perivascular and perifollicular lymphohistiocytic infiltrate develops. Sebaceous hyperplasia may be prominent in some patients. The most severe forms of disease show perifollicular noncaseating epithelioid granulomas. Treatment may include topical metronidazole as for rosacea (once or twice daily), azelaic acid cream, benzyl peroxide preparations, and to a lesser degree, topical erythromycin, clindamycin, or tetracycline. Oral tetracycline, doxycycline, or minocycline may also be helpful in presentations that are more resistant.     

Topical metronidazole does not abate UVB-induced erythema

BACKGROUND: The capacity of topical metronidazole to reduce erythema severity scores in rosacea has been attributed to its anti-inflammatory activity. METHODS: Nine healthy subjects were irradiated on three 1-cm(2) areas on their volar forearm with 2 MEDs of UVB. Twenty-four hours later, one of the irradiated areas was treated daily with metronidazole 1% vanishing cream, one with the vehicle only and the third was left untreated (control). The intensity of erythema was measured, at 24, 48, 72 and 96 h after irradiation, by a Chromameter CR200 (Minolta, Japan) and expressed in the L*a*b* system. The a* parameter was taken as the measure of redness. RESULTS: Overall, redness diminished over time in a linear way, but treatments did not influence it significantly. CONCLUSION: In our vehicle, metronidazole 1% cream failed to abate the UVB-induced erythema. An activity other than the anti-inflammatory one should be suggested to explain the topical metronidazole efficacy in rosacea.     

A randomized, single-blind, placebo-controlled, split-face study with pimecrolimus cream 1% for papulopustular rosacea

Background Rosacea is a common inflammatory skin disorder for which the pathogenesis is unclear. Currently, there is no cure for rosacea, and it seems that standard therapies have focused mainly on minimizing inflammation. Objectives The aim of this study is to investigate the potential efficacy, tolerability and safety profile of 1% pimecrolimus cream for the treatment of rosacea. Methods Twenty‐five patients with papulopustular rosacea were enrolled to a randomized, single‐blinded, placebo‐controlled, split‐face trial of pimecrolimus cream 1% consisting 4 week treatment and 2 week follow‐up period. The patients were instructed to apply first the ‘left side cream’ labelled placebo cream (Ultrabase cream, Intendis GmbH, Berlin, Germany) to the left hemi‐face then the ‘right side cream’ labelled 1% pimecrolimus cream (Elidel; Novartis Pharma, Nuremberg, Germany) to the right hemi‐face, twice daily. They were informed to apply a standard amount of each cream with the fingertip‐unit and not allowed to use any other agent concomittantly other than sunblock. Clinical evaluation and subjective severity assessment were obtained along with photographic documentation at baseline, first, second, and fourth weeks of the therapy and at the follow‐up visit. Rosacea severity score for each sign of erythema, papules, pustules, oedema, and telengiectesia were graded from 0 to 3. Patients were questioned for the subjective symptoms, overall improvement on appearance and side‐effects. Results Twenty‐four patients completed the study with an exceptional compliance and tolerable safety profile. One patient withdrew from the study due to severe flare‐up reaction affecting both hemi‐faces. The mean baseline total rosacea severity scores were 5.06 + 1.29 for both sides and reduced to 2.5 ± 1.06 vs. 3.25 ± 1.24 on pimecrolimus vs. placebo applied sides without the significance (P = 0.06). There was not any significant difference concerning each rosacea sign scores and total rosacea severity scores except for the significant improvement in erythema score and total rosacea severity score obtained on the pimecrolimus‐applied hemi‐face at 2nd week of therapy (P =0.01 and P = 0.03, respectively). The reduction rates of the mean subjective severity scores at 4th week were 49.77% vs. 38.89% for pimecrolimus vs. placebo, respectively, without a statistical significance (P = 0.15). Subjective symptoms responded well in 54.16% of patients concerning pimecrolimus application compared with 12.50% for the placebo application. The side‐effects were mostly transient local irritations. Conclusion Our data implicated that pimecrolimus cream is not superior to placebo except for its efficacy on erythema. We believe that pimecrolimus cream can be a treatment option for rosacea patients with high erythema score for whom an initial accelerated improvement is needed. We believe further studies with topical pimecrolimus cream on larger study groups with different subtypes and severity of rosacea will clarify the potential effect of pimecrolimus cream for the treatment of rosacea.
