BACKGROUND: SDZ ASM 981 is a selective inhibitor of inflammatory cytokines released from T lymphocytes and mast cells, which has been developed for the treatment of inflammatory skin diseases. OBJECTIVES: In the present study, the atrophogenic potential of SDZ ASM 981 1% cream in humans was compared with that of medium and highly potent topical steroids, and vehicle. METHODS: Four different preparations, SDZ ASM 981 1% cream, the corresponding vehicle of SDZ ASM 981 1% cream, betamethasone-17-valerate 0.1% cream and triamcinolone acetonide 0.1% cream, were applied to the volar aspect of the forearms of 16 healthy volunteers, twice daily, 6 days a week, for 4 weeks. Skin thickness was evaluated by ultrasound examination, clinical signs of atrophy by stereomicroscopy, and epidermal thickness was assessed by histology. RESULTS: Both topical corticosteroids induced a significant reduction in skin thickness, as compared with SDZ ASM 981 1% cream and vehicle, which were shown to be equivalent. The difference in skin thickness (measured by ultrasound examination) between patients treated with SDZ ASM 981 1% cream and those receiving either of the two topical steroids was significant from day 8 onwards. Histological analysis performed at day 29 showed significant epidermal thinning with topical steroids compared with SDZ ASM 981 1% cream or the vehicle. Conclusion The lack of atrophogenic properties of SDZ ASM 981 1% cream in this short-term study demonstrates its potential as long-term treatment for inflammatory skin diseases, thus overcoming a major drawback of topical steroids. This may also be important for the treatment of children, and sensitive areas of skin, such as the face and skin-folds. 相似文献

BACKGROUND: SDZ ASM 981 is a selective inhibitor of inflammatory cytokine release under development for the topical treatment of atopic dermatitis. OBJECTIVES: This first paediatric study was designed to measure the systemic exposure to SDZ ASM 981 in young children with atopic dermatitis treated on extensive skin areas. METHODS: Children 1-4 years of age referred to a tertiary care centre for their atopic dermatitis were treated twice daily for 3 weeks with 1% SDZ ASM 981 cream. SDZ ASM 981 blood concentrations were measured on day 4 and 22 (last day) of treatment, and 1 week after the last application, using a radioimmunoassay with a limit of quantification of 0.5 ng mL(-1). Efficacy was assessed by the Eczema Area Severity Index (EASI). RESULTS: The 10 patients included had 23-69% of their body surface area (BSA) affected at baseline. Of the 63 SDZ ASM 981 blood concentrations measured, 63% were < 0.5 ng mL(-1); the maximum value observed was 1.8 ng mL-1. No accumulation was evidenced between days 4 and 22. The first two patients experienced a flare of atopic dermatitis that was not controlled by the study medication. In the other patients, the EASI improved by 8-89% at 3 weeks of treatment. CONCLUSIONS: In these children 1-4 years of age, blood concentrations of SDZ ASM 981 during topical treatment with the 1% cream were consistently low even in the children with the most extensive areas treated (up to 69% of their BSA). 相似文献

The novel ascomycin derivative SDZ ASM 981 is effective for psoriasis when used topically under occlusion 总被引:5,自引:0,他引:5

Topical SDZ ASM 981 has been found to be highly effective in preclinical models of T-cell-mediated skin disease. T cell activation is crucial in the pathogenesis of psoriasis. It has been hypothesized that SDZ ASM 981 may prove to be an effective treatment for chronic plaque psoriasis. Therefore, the study objective was to determine the efficacy, tolerability and safety of the new topical macrolactam, SDZ ASM 981, for chronic plaque psoriasis. Ten patients with chronic plaque-type psoriasis were treated with SDZ ASM 981 (0.3% and 1.0%), the corresponding ointment base (placebo) and open-labelled clobetasol-17-propionate ointment (0.05%) in a randomized, double-blind, within-subject comparison for 2 weeks using the microplaque assay. Evaluation was performed by daily determination of clinical scores for erythema and induration. The results of the study showed that, after 2 weeks of treatment, total scores decreased by 92% for clobetasol, by 82% for 1% SDZ ASM 981, by 63% for 0.3% SDZ ASM 981 and by 18% for the ointment base (placebo). No adverse drug effects were seen in any patient throughout the study. We conclude from our results that the new macrolactam SDZ ASM 981 (1%) is similar to clobetasol-17-propionate (0.05%) in plaque-type psoriasis when applied topically under occlusion for 2 weeks using the microplaque assay. 相似文献

A novel anti-inflammatory drug, SDZ ASM 981, for the topical and oral treatment of skin diseases: in vivo pharmacology 总被引:1,自引:0,他引:1
J.G. MEINGASSNER M. GRASSBERGER H. FAHRNGRUBER H.D. MOORE H. SCHUURMAN A. STÜTZ 《The British journal of dermatology》1997,137(4):568-576
There is a need for safe and effective therapies for inflammatory skin diseases. Current topical and systemic treatment of psoriasis is effective but suffers from side-effects or is inconvenient. The therapeutic armamentarium for atopic dermatitis is very limited and far from satisfactory. In vivo preclinical data are presented for SDZ ASM 981, a novel ascomycin macrolactam derivative with high anti-inflammatory activity. Anti-inflammatory activity was observed in mouse, rat and pig models of allergic contact dermatitis. In the pig model, topical SDZ ASM 981 was as effective as the ultrapotent corticosteroid clobetasol-17-propionate, and when compared with a series of commercial topical corticosteroid preparations, 0·1% SDZ ASM 981 had equivalent efficacy to clobetasol-17-propionate (0·05%), the most potent product on the market. Unlike the corticosteroid, however, SDZ ASM 981 did not cause skin atrophy in pigs. SDZ ASM 981 potently inhibited allergic contact dermatitis in mice and rats when given systemically, and oral treatment was more effective than cyclosporin A in rats. Furthermore, SDZ ASM 981 has a low potential for affecting systemic immune responses, as demonstrated in rat models of localized graft vs. host reaction and allogeneic kidney transplantation. Preclinical results suggest that SDZ ASM 981 has the potential to be a well-tolerated and effective drug for topical as well as oral treatment of inflammatory skin diseases. 相似文献

The same glucocorticoid in brand-name products. Does increasing the concentration result in greater topical biologic activity? 总被引:1,自引:0,他引:1
Many topical corticosteroid formulations are available as different concentrations of the steroid in a similar vehicle. We tested the existing assumption that higher concentrations give greater biologic activity. The vasoconstriction assay was used because of its known correlation with clinical activity. Statistical analyses of the different concentrations are as follows: Kenalog creams: 0.025% is equal to 0.1% is equal to 0.5%; Aristocort creams: 0.025% is equal to 0.1% is equal to 0.5%; Aristocort ointments: 0.1% is equal to 0.5%; Aristocort creams: 0.5% is equal to 0.025% but is less than 0.1%; Hytone cream: 1.0% is equal to 2.5%; Synalar creams: 0.01% is less than 0.025% which is less than 0.2%; Topicort creams: 0.25% is equal 0.05%; and Vallisone creams: 0.1% is greater than 0.01%. The assumption that increased concentration of the same steroid in the same vehicle type will give increased biologic activity is usually, but not always, incorrect for brand-name formulations now available. 相似文献

Pimecrolimus (SDZ ASM 981), an ascomycin derivative, is a nonsteroid, has anti-inflammatory activity, and has demonstrated efficacy in reducing symptoms of atopic dermatitis in adult and pediatric patients when applied topically. Compared with vehicle, topical pimecrolimus 1.0% cream was significantly more effective at reducing symptoms of atopic dermatitis, as measured by the Eczema Area and Severity Index (EASI), in infants aged 3 to 23 months, children aged 2 to 17 years, and adults. The median reductions from baseline in the total EASI score in adults after treatment with pimecrolimus 1.0% or corresponding vehicle twice daily for 3 weeks were 47 and 0%, respectively. In infants and children, treatment with pimecrolimus 1.0% twice daily for 6 weeks resulted in significant decreases in mean EASI scores compared with vehicle. The severity of pruritus was significantly reduced in patients of all age groups after topical treatment with pimecrolimus 1.0% cream. Compared with vehicle, the incidence of eczematous flares was also reduced by intermittent long-term use of topical pimecrolimus 1.0% in adults, children and infants. Sixty-one percent of children treated with pimecrolimus for 1 year completed the first 6 months of treatment without experiencing a flare, compared with 35% of patients who received vehicle. Furthermore, the use of topical corticosteroids for the treatment of uncontrolled flares in adults, children and infants was lower in the pimecrolimus groups than in the vehicle groups. Topical pimecrolimus 1.0% cream is well tolerated in atopic dermatitis patients of all age groups. There were no clinically relevant systemic adverse events reported from any of the studies in patients with atopic dermatitis. The most frequently reported adverse events pertained to application site reactions, such as burning and a feeling of warmth. In conclusion, topical pimecrolimus 1.0% cream has shown efficacy in the treatment of mild to moderate atopic dermatitis in infants, children and adults. Although tolerability data concerning infants and children have not yet been published in full, the drug appears to be well tolerated in all age groups, and there have been no reports of clinically relevant systemic adverse events. Furthermore, pimecrolimus has shown no potential for skin atrophy, a problem commonly associated with treatment with topical corticosteroids. Topical pimecrolimus 1.0% provides a promising and well tolerated treatment option in the management of infants, children and adults with mild to moderate atopic dermatitis. 相似文献

BACKGROUND: Pimecrolimus cream 1% (Elidel, SDZ ASM 981) is a novel, non-steroid inflammatory cytokine inhibitor, effective in the treatment of atopic dermatitis. Here, we evaluate the treatment of chronic hand dermatitis with pimecrolimus cream 1%. OBJECTIVES: To determine pimecrolimus blood concentrations, and evaluate the safety, tolerability and efficacy following application of pimecrolimus cream 1% to subjects with chronic hand dermatitis. METHOD: In this open-label, multiple-topical-dose, non-controlled, pharmacokinetic study, pimecrolimus cream 1% was applied twice daily to dorsal and palmar areas (affected and unaffected) of both hands. Evening applications (except day 8) were immediately followed by overnight occlusion (> or =6 h). Full pharmacokinetic profile (days 1, 8 and 22), trough concentrations (days 3 and 15), physical examinations, laboratory measurements and adverse events were recorded. Efficacy was assessed via Investigators' Global Assessment (IGA), total key signs and symptoms and the subject's overall self-assessment. RESULTS: Twelve patients completed the study. The majority of pimecrolimus blood concentrations (73.6%) remained below the limit of quantitation (0.1 ng/ml). The maximum concentration observed was 0.91 ng/ml and the maximum area under the concentration-time curve from 0-12 h post dose was 7.6 ng.h/ml. Treatment was well tolerated locally and systemically. No serious adverse events occurred; 4/13 subjects showed a total of 6 adverse events at the application site: burning (n=4), and pruritus (n=2). No clinically relevant or drug-related changes were observed. Clear efficacy of the treatment was shown by all 3 assessment methods. Disease state at day 22 had improved in 11 (85%) subjects compared with baseline (IGA). CONCLUSION: Twice daily topical treatment of moderate to severe chronic hand dermatitis with pimecrolimus cream 1% results in low pimecrolimus blood levels, is well tolerated, safe, and effective. 相似文献

Magnesium deficiency in hairless rats results in a transient erythematous rash within several days, the pathogenetic mechanisms of which are not yet well defined. However, the extremely pruritic rash closely mimics the acute clinical features of atopic dermatitis. Owing to the similarity of clinical signs between hypomagnesaemic rats and patients with atopic dermatitis, this rodent skin condition holds promise as a model for the in vivo evaluation of new treatment modalities against pruritic inflammatory skin conditions. The efficacy of the new ascomycin macrolactam derivative SDZ ASM 981 was tested in hypomagnesaemic rats by systemic or topical administration using prophylactic or therapeutic treatment regimens. Oral treatment of diseased rats with SDZ ASM 981 (12.5 mg kg-1 daily) inhibited the erythematous pruritic rash within 1 day after the start of treatment. This was associated with a clear reduction in histaminaemia, leucocytosis, eosinophilia and serum nitric oxide levels. The same daily oral dose of SDZ ASM 981 administered before the onset of the rash proved to be an efficacious prophylactic treatment regimen to prevent signs. Topical treatment of the ears with 0.4% SDZ ASM 981 locally inhibited and prevented inflammatory changes in a therapeutic and prophylactic treatment regimen, respectively. The histo- and immunopathological skin changes, as well as the numbers of degranulated mast cells in the dermis, were reversed towards normal after oral and topical administration. The pharmacological activity of SDZ ASM 981 reported here corresponds well to its anti-inflammatory and antipruritic activity observed in atopic dermatitis patients, confirming the usefulness of this rat model in drug evaluations. 相似文献

BACKGROUND: Pimecrolimus cream (Elidel, SDZ ASM 981), a non-steroid inhibitor of inflammatory cytokines, is effective in the treatment of atopic dermatitis (AD). We assessed whether early treatment of AD signs/symptoms reduces the need for topical corticosteroids. OBJECTIVE: To investigate the efficacy and safety of pimecrolimus cream 1% in the long-term management of adult AD. METHODS: 192 adults with moderate to severe AD were randomised (1:1) for twice daily (b.i.d.) treatment of early signs or symptoms of AD with either pimecrolimus cream 1% or vehicle cream (control group) to prevent progression to flares. Treatment was given as needed for 24 weeks. In the event of flares, a moderately potent corticosteroid (prednicarbate 0.25% cream) was permitted as rescue medication in both groups. The percentage of days on which a topical corticosteroid was used to treat disease flares was the main outcome measure. RESULTS: Corticosteroid medication was used on 14.2% (95% confidence interval, CI: 8.3-21.1) of the days of the 24-week treatment period in the pimecrolimus group and on 37.2% (95% CI: 30.4-44.0) of the days in the control group (p < 0.001). In total, 44.8% (43/96) of patients in the pimecrolimus group did not experience a flare compared with 18.8% (18/96) of patients in the control group. The median time to first flare was 144 days in the pimecrolimus group and 26 days in the control group (p < 0.001). Pimecrolimus treatment was also associated with improvement in signs and symptoms of AD, pruritus, patients' self-assessment and quality of life. CONCLUSIONS: Pimecrolimus cream 1% b.i.d. is an effective, well-tolerated, long-term treatment for AD in adults, substantially reducing the number of flares compared to a conventional therapy and consequently reducing or eliminating the need for corticosteroid treatment. 相似文献

BACKGROUND: Tazarotene in a gel formulation is widely used in the treatment of psoriasis. OBJECTIVE: To determine the efficacy and safety of tazarotene 0.1% and 0.05% creams in the treatment of psoriasis. METHODS: A total of 1303 patients participated in 2 clinical trials. Patients applied tazarotene creams 0.1% and 0.05% or vehicle once daily to all psoriatic lesions for 12 weeks followed by a 12-week posttreatment period. RESULTS: Both creams were significantly more effective than vehicle on the basis of an overall assessment of psoriasis, a global response to treatment, and reduction in plaque elevation and scaling. Therapeutic effect was maintained during the posttreatment period. Common adverse events included signs and symptoms of skin irritation. CONCLUSION: Tazarotene creams were associated with significant reductions in the severity of the clinical signs of psoriasis and were found to be safe with acceptable tolerability. Tazarotene cream 0.1% was generally more effective, although slightly less well tolerated, than the 0.05% cream. 相似文献

BACKGROUND: The ascomycin derivative pimecrolimus (ASM 981) is a cell-selective cytokine inhibitor, specifically developed for the treatment of inflammatory skin diseases. OBJECTIVE: When applied topically, pimecrolimus cream 1% has shown promise as a treatment for inflammatory skin conditions, including atopic dermatitis (AD) in children and adults, allergic contact dermatitis, and chronic contact irritant hand dermatitis in adults. METHODS: In two independent 6-week, randomized, multicenter studies of identical design, the efficacy and safety of pimecrolimus cream 1% in children with predominantly moderate AD were compared with vehicle. Pooled data from a total of 403 patients were used in the analysis. The primary efficacy parameter was the Investigator's Global Assessment (IGA) score. Secondary parameters included Eczema Area and Severity Index (EASI) and severity of pruritus scores. Subjects were also asked to assess their disease control as uncontrolled, limited, good, or complete. RESULTS: Significant therapeutic benefits relative to vehicle were observed in the pimecrolimus-treated group at the first efficacy assessment, 8 days after initial application of the study medication (eg, relief of pruritus). At each subsequent postbaseline visit, pimecrolimus-treated patients showed significant improvement relative to controls in all efficacy measures. The medication was well tolerated. CONCLUSION: Pimecrolimus cream 1% appears to be a safe and effective alternative to currently used therapies for AD. 相似文献

AIM: To report on quality of life (QoL) and health-related quality of life (HRQL) impacts of pimecrolimus (Elidel, Novartis A.G., Basel, Switzerland, SDZ ASM 981) 1% cream in the long-term treatment of paediatric atopic dermatitis. METHODS: QoL and HRQL data are presented from two 12-month international clinical trials evaluating the efficacy and safety of pimecrolimus 1% cream. Both trials were randomized and double blinded and compared two treatment strategies, one involving the use of emollients, pimecrolimus and topical corticosteroids, the other is 'usual care' (emollients plus topical corticosteroids) with a vehicle cream to maintain study blinding. The first trial (the infant trial) involved patients between ages 3 months and 2 years, whereas the children trial included patients aged 2-17 years. In both trials, QoL of the affected child's parent was evaluated with the parent's index of quality of life in atopic dermatitis (PIQoL-AD). HRQL was assessed in the children trial only with the children's dermatology life quality index (CDLQI). QoL and HRQL assessments were conducted at baseline, 6 weeks, 6 months and 12 months. RESULTS: Generalized linear modelling of PIQoL-AD scores at each post-baseline visit showed a greater impact on parent's QoL for pimecrolimus compared with control at all time-points in both trials. HRQL scores showed a greater improvement from baseline for children in the pimecrolimus group compared with those in the control group at all time-points. CONCLUSIONS: The results show a beneficial impact of pimecrolimus on parents' QoL in paediatric atopic dermatitis, confirming findings from earlier shorter term trials. There was also a clear benefit to the HRQL of the children treated. 相似文献

Pimecrolimus (Elidel, SDZ ASM 981), a new macrolactam ascomycin derivative, was highly effective in treating plaque-type psoriasis when applied under Finn-chamber occlusion. A two-centre, randomized, double-blind, vehicle- and positive-controlled within-patient study was therefore conducted in 23 adult psoriasis patients. Pimecrolimus 1% was applied, twice daily, in an experimental ointment formulation, along with the corresponding vehicle, 0.005% calcipotriol ointment and 0.05% clobetasol-17-propionate ointment to test sites without occlusion for 21 days. Erythema, induration and scaling (score: 0 [absent] to 4 [severe]) were evaluated. The total sign score was defined as the sum of the erythema, induration and scaling scores (range 0-12). Pimecrolimus 1% ointment was significantly (p = 0.03) more effective than the corresponding vehicle, with an improvement in total sign score of 51.4% compared with 36.7% for the corresponding vehicle. Improvements with calcipotriol and clobetasol-17-propionate were 71.5% and 88.3%, respectively. No local or systemic drug-related side effects were observed in the study. We conclude that pimecrolimus 1% in the experimental ointment formulation was significantly more effective than its corresponding vehicle, but less effective than calcipotriol and clobetasol ointment. This is the first study reporting a significant therapeutic effect of pimecrolimus in an ointment formulation applied without occlusion to psoriatic plaques. 相似文献

Effect of pimecrolimus vs. corticosteroids on murine bone marrow-derived dendritic cell differentiation, maturation and function 总被引:2,自引:0,他引:2
Abstract: Pimecrolimus (SDZ ASM981) is a non-steroid member of calcineurin inhibitors recently developed for the treatment of inflammatory skin diseases. In this study, we compared the effect of pimecrolimus and corticosteroids on the differentiation, maturation and function of murine bone marrow-derived dendritic cells (BM-DC). We added pimecrolimus at concentrations of 5–500 ng/ml or 0.5 ng/ml mometasone furoate at different timepoints to the BM-DC culture and checked (i) the number of matured cells, (ii) the expression of activation markers, (iii) the release of cytokines and (iv) the stimulatory capacity of the resulting BM-DC in vivo . Even at the highest concentration, pimecrolimus treatment resulted in only modest effects. In the pimecrolimus-treated culture, we observed a decrease in the numbers of matured cells but no significant effects on the expression of activation markers. The release of some inflammatory cytokines was reduced, but the stimulatory capacity in vivo was not affected. In contrast, mometasone furoate has pronounced effects on BM-DC at a concentration ten to 1000 times lower than those used with pimecrolimus. Furthermore, topical treatment of mice with clobetasole cream 0.05% resulted in almost complete depletion of splenic DC and a severe hyposplenia, while high-dose oral pimecrolimus treatment did not show any effects on the spleen or on splenic DC. These results support that pimecrolimus, unlike corticosteroids, has little effects on dendritic cells. To the best of our knowledge, this is the first study of this type with use of BM-DC. 相似文献

This research, from Korea, showed that a non-steroid containing cream, called PAC-14028, can be as effective in treating eczema symptoms as current creams on the market but with fewer side-effects. Eczema is one of the most common skin diseases. Available topical (applied to the skin) treatments can be very effective in treating eczema symptoms. However, they can also cause negative side-effects such as itching and burning, which can result in patients discontinuing their treatment. The research was conducted with 194 adults with mild to moderate eczema. Participants were split into four groups and treated with either a control cream or the new treatment, PAC-14028 cream, at one of three different concentrations (0.1%, 0.3% or 1.0%). Participants applied the cream twice daily for eight weeks. The results were primarily measured using the Investigator's Global Assessment (IGA). This is a visual scale for assessing the severity of eczema in a patient based upon typical symptoms. After eight weeks, 57.5 percent of patients in the group who received the highest concentration PAC-14028 cream, had an IGA score indicating that their symptoms of eczema were completely eradicated or reduced to an almost-clear level. IGA success rates at week eight were 15 percent for the control cream, compared to 43 percent for PAC-14028 cream at 0.1%, 38 percent for 0.3% and 57 percent 1.0%. The efficacy of PAC-14028 cream was similar to a commonly used non-steroidal cream called pimecrolimus but with a far lower incidence of unwanted side-effects. 相似文献

Background: Corticosteroids are a versatile option for the treatment of mild-to-moderate psoriasis due to their availability in a wide range of potencies and formulations. Occlusion of the corticosteroid is a widely accepted procedure to enhance the penetration of the medication, thereby improving its effectiveness. Betamethasone valerate (BMV) is a moderately potent corticosteroid that is available as a cream, ointment, and lotion. A ready-to-use occlusive dressing, which provides a continuous sustained release of BMV, has been developed for the treatment of psoriasis. Objective: To evaluate the efficacy and safety of a new BMV 0.1% plaster compared with a BMV 0.1% cream in patients with mild-to-moderate chronic plaque psoriasis. Methods: This was a prospective, randomized, assessor-blind, parallel-group, active-controlled, multicenter, phase III study. Eligible outpatients (aged ≥18 years) with a diagnosis of stable, chronic plaque psoriasis vulgaris with two to four plaques on extensor surfaces of limbs were randomized to receive BMV 0.1% plaster or BMV 0.1% cream for 3–5 weeks; patients with resolution of target plaques then entered a 3-month, treatment-free, follow-up period. The number of patients showing clearing of plaques (remission) at 3 weeks (primary endpoint) and at 5 weeks was independently evaluated from digitized images of target plaques by two blinded assessors, and also assessed by the investigator and patient. Additional endpoints were (i) change from baseline in target plaque size and in Psoriasis Global Assessment (PGA) score, as evaluated by the blinded assessors, investigator, and patient; (ii) change from baseline in symptom (itching, soreness) severity; (iii) treatment satisfaction and ease of use; (iv) clearing and relapse during the follow-up period; and (v) adverse events (AEs). Results: Patients (n = 231) were screened and randomized to treatment with BMV 0.1% plaster (n = 116) and BMV 0.1% cream (n = 115). Significantly more patients achieved clearing after 3 weeks’ treatment with BMV plaster than with BMV cream (Cochran-Mantel-Haenszel test, p < 0.001); this difference was maintained at 5 weeks. The total plaque area decreased to a larger extent for the BMV plaster group compared with the BMV cream group (analysis of covariance [ANCOVA] model, p = 0.017 at week 5). PGA scores were significantly lower after 3 and 5 weeks’ treatment with BMV plaster (ANCOVA model, all p ≤ 0.016 vs BMV cream). Both treatments reduced itching and soreness to a similar degree, and the incidences of relapse during the follow-up period were comparable between treatment groups. There were no significant differences in AEs between treatment groups. Conclusions: BMV 0.1% plaster is more efficacious than BMV 0.1% cream in the treatment of patients with mild-to-moderate chronic plaque psoriasis in a clinical setting resembling daily clinical practice.

BACKGROUND: Betamethasone valerate (BMV) is a medium-potency corticosteroid commonly used for the treatment of chronic psoriasis. Although occlusion has been shown to enhance the efficacy of BMV treatment, no ready-to-use occlusive BMV formulation is currently approved for the market. METHODS: Forty-two patients with mild to moderate psoriasis and with symmetrical lesions were treated with BMV 0.1% tape and BMV 0.12% cream for 30 days in a half-side distribution. Both treatments resulted in a significant clinical improvement. Efficacy and tolerability were evaluated by comparison of pre-treatment and post-treatment psoriasis area and severity index and self-administered psoriasis area and severity index scores, and by comparison of the changes from baseline in clinical appearance and hydration. RESULTS: Lesions treated with BMV 0.1% tape showed higher reductions from baseline in the psoriasis area and severity index and the self-administered psoriasis area and severity index scores (61.7% and 59.3%, respectively), compared with lesions treated with BMV 0.12% cream (39.5% and 34.0%, respectively). No serious local or systemic treatment-related adverse effects were reported. CONCLUSIONS: Our results indicate a higher efficacy of BMV 0.1% tape compared with BMV 0.12% cream in the treatment of mild to moderate chronic plaque psoriasis. 相似文献

SUMMARY.— In a double blind test a 0·1% hydrocortisone butyrate o/w cream under plastic occlusion was as effective as 0·1% triamcinolone acetonide in the same vehicle and significantly better (on the 0·001 level) than hydrocortisone acetate 1% cream. The possibility is discussed that the systemic effects of 0·1% hydrocortisone butyrate creams will prove to be less than those of 0·1%, triatncinolone acetonide creams. 相似文献
