Granuloma annulare on the palms in an elderly patient

Abstract: Granuloma annulare is a relatively common, idiopathic, benign inflammatory dermatosis, with a varied clinical presentation that often makes diagnosis difficult. It mainly affects the extremities, such as the dorsa of the hands and feet, forearms and legs. Palmar and plantar regions are generally spared. It occurs mainly in young female patients. The presentation of the palmar variant in an elderly patient is a rarity.

Pitiriasis liquenoide crónica en un adulto mayor: reporte de un caso / Pityriasis lichenoides in an older adult: report of a case

La pitiriasis liquenoide crónica (PLC) es una enfermedad benigna, que se caracteriza por tener un curso gradual, con aparición de múltiples pápulas con escamas adherentes de predominio en tronco y extremidades proximales. Con el objetivo de describir la presentación clínica, discutir el diagnóstico, diagnósticos diferenciales, tratamiento y revisar la literatura se presenta el caso de un hombre de 88 años que presentó múltiples lesiones papuloescamosas en extremidades inferiores. Se realizó biopsia cutánea que confirmó el diagnóstico de PLC. El paciente recibió tratamiento con emulsión hidratante, clobetasol tópico y claritromicina con resolución completa de las lesiones. La pitiriasis liquenoide crónica es un trastorno inflamatorio poco frecuente, de etiología desconocida que ocurre más comúnmente en adultos jóvenes y niños. Si bien la clínica es sugerente, se requiere biopsia cutánea para su confirmación diagnóstica. Es un trastorno benigno, a menudo asintomático y autolimitado, por lo que se debe valorar su tratamiento paciente a paciente. Principalmente se utilizan corticoides tópicos y antibióticos orales (tetraciclinas y eritromicina). Se ha vinculado en escasas publicaciones con el desarrollo de linfoma cutáneo y como síndromes paraneoplásicos, por lo que se sugiere realizar seguimiento.

Chronic lichenoid pityriasis (PLC) is a benign disorder, characterized by a gradual course with the appearance of multiple squamous papules with adherent scales predominating in the trunk and proximal extremities. With the objective to describe its clinical presentation, diagnosis, differential diagnosis, treatment and review literature, we present an 88-yearold male with multiple lesions in the lower extremities of one year of evolution, with papules and adherent scales. A skin biopsy was performed that confirmed the diagnosis of PLC. The patient received treatment with moisturizing emulsion, clobetasol topical and clarithromycin with complete resolution of the lesions. Chronic lichenoid pityriasis is a rare inflammatory disease of unknown etiology that occurs most commonly in young adults and children. Although the clinic is suggestive, a skin biopsy is required for diagnostic confirmation. It is a benign disorder, often asymptomatic and self-limiting, so its patientto- patient treatment should be assessed. Topical corticosteroids and oral antibiotics (tetracyclines and erythromycin) are used. It has been linked in few publications with the development of cutaneous lymphoma and as paraneoplastic syndromes, so it is suggested to follow up.

Bilateral clear cell acanthoma of the areola and nipple: good response to topical corticosteroids

Abstract: Clear cell acanthoma is a rare, epidermal tumor not common in the area of the nipples; indeed, the literature describes only 8 cases, all showing unilateral presentation. We here report the first case of bilateral clear cell acanthoma with good response to topical corticosteroids. Case report: A sixteen-year old girl presented with 2 excrescent, fleshy, and exudative tumor masses in both nipples and areola mammae. A biopsy was conducted and confirmed clear cell acanthoma histopathologically. Treatment with strong corticosteroids resulted in rapid improvement and resolution. After one year of follow-up, the patient developed atopic dermatitis. Discussion: We describe the first case of bilateral clear cell acanthoma localized in the nipple/areola that resolved with powerful corticosteroids, suggesting a reactive etiology of the lesion.

The reservoir effect of topical steroids in vitiliginous skin: A cross-sectional study.

Background: Prolonged and frequent use of topical steroids may lead to decrease in effi cacy as well as many local adverse effects. Stratum corneum has a unique property of reservoir effect. Aims: To study the reservoir effect of topical steroids in a steroid-responsive condition which may enable a decrease in the dosing frequency of topical steroids. Methods: A cross-sectional study design was used. Patients with at least three vitiliginous patches of more than 2 cm2 present over the trunk or limbs were included. Exclusion criteria were topical or systemic corticosteroid use within the previous 4 weeks, antihistamine use within the previous 7 days, history of any allergy in the past and immunosuppression. Clobetasol propionate cream was applied on the fi rst vitiliginous area (site A) and fl uticasone propionate ointment was applied on the second vitiliginous area (site B). The third vitiliginous area, site C (control site) was left without applying any medication. Histamine-induced wheal suppression test was performed on each site, at the same time of the day, on every consecutive day following steroid application, until the values obtained at sites A and B approached those obtained at site C. SPSS software for Windows, version 16.0 was used for statistical analysis. The mean and standard deviation of the various studied parameters were calculated for various treatment groups and compared using analysis of variance (ANOVA) test. Results: Forty patients were included in the study. The average wheal volumes and average erythema sizes at sites A and B were signifi cantly smaller than the corresponding values at site C for up to 5 days after applying medication (P < 0.001). Limitations: The presence of a cutaneous reservoir of topical steroid was confi rmed based on its suppressive effect on the wheal and fl are response to histamine. It is not certain that the concentration that suppresses histamine-induced wheal and fl are is suffi cient for therapeutic effi cacy in vitiligo. Conclusion: The reservoir effect of topical clobetasol propionate and fl uticasone propionate persisted for 5 days in vitiliginous skin. Hence, it may be possible to reduce the frequency of topical steroid application in vitiligo.

Evaluation of Efficacy, Safety and Tolerability of a Combination of Clobetasol, Neomycin and Miconazole Versus Betamethasone, Clotrimazole and Neomycin Versus Betamethasone, Gentamycin and Miconazole in Subjects with Eczematous Disorders Associated with underlying Tinea or Yeast Infections.

Lobate GM Neo, 15 mg is a triple drug combination of a steroid clobetasol with anti-fungal miconazole and antibacterial neomycin in treatment of Eczematous disorders associated with underlying Tinea or Yeast Infections. Aims and Objectives: The study was designed to evaluate the efficacy, safety and tolerability of a combinations of clobetasol, neomycin and miconazole (Group A) versus betamethasone, clotrimazole, neomycin (Group B) versus betamethasone, gentamicin, miconazole (Group C) in subjects with any type of eczematous disorder associated with underlying tinea or yeast infection. Materials and Methods: This was an open label, parallel group, randomized comparative study. The primary endpoint analyzed was improvement in clinical score from baseline at the end of day 7 and other primary endpoint like hyperpigmentation were analyzed by the visual analogue scale of 1 to 10 at the end of day 7. Results: Thirty-six subjects were randomized to three groups. The clinical score showed a significant reduction from baseline at the end of day 7 in all the groups, i.e. 82.9%, 81.3% and 85.6% in Group A, B and C respectively. However, the difference between the groups were not statistically significant. Mean hyper pigmentation score showed significant decrease of 82.9% in Group A, 81.6% in Group B and 92.2% in Group C from baseline at the end of day 7. Conclusion: The triple combination of antifungal, antibacterial and potent steroid was found to be efficacious, safe and tolerable in reducing signs and symptoms (scaling, inflammation, burning and itching) of eczematous disorder associated with underlying tinea/yeast infection.

An Open, Comparative, Randomized, Parallel, Post Marketing, Multicentric Trial to Compare the Safety and Efficacy of Formula A (Ofloxacin + Ornidazole + Terbinafine Hydrochloride + Clobetasol Propionate) versus Formula B (Clotrimazole + Beclometasone Dipropionate + Neomycin Sulphate), Formula C (Clotrimazole + Beclometasone Dipropionate + Neomycin Sulphate) and Formula D (Clotrimazole + Beclometasone Dipropionate + Neomycin Sulphate) in the Treatment of Patients with Vaginitis.

Vaginitis is among the most common conditions for which women seek medical care, with vaginal discharge accounting for approximately 10 million office visits each year. Since there are no published studies till date that evaluated the Clinical Effectiveness and Safety of Topical Cream of Formula A [Ofloxacin (0.75 % w/w) + Ornidazole (2% w/w) + Terbinafine Hydrochloride (1% w/w) + Clobetasol Propionate (0.05% w/w)] compared to Formula B [Clotrimazole (1%w/w) + Beclometasone Dipropionate (0.025%w/w) + Neomycin Sulphate (0.5% w/w)], Formula C [Clotrimazole (1%w/w) + Beclometasone Dipropionate (0.025%w/w) + Neomycin Sulphate (0.5% w/w)], and Formula D [Clotrimazole (1%w/w) + Beclometasone Dipropionate (0.025%w/w) + Neomycin Sulphate (0.5% w/w)], in mild to moderate vaginitis, hence we undertook this randomized controlled Post Marketing Multicentric trial. Materials and methods: Female subjects diagnosed with mild to moderate symptoms of Vaginitis were eligible and those fulfilling the subject selection criteria were randomized to receive either Formula A, Formula B, Formula C or Formula D for 14 days. The Primary efficacy measures were assessment of symptoms of Vaginitis i.e. vaginal pruritis, vaginal irritation, vaginal soreness or pain, dyspareunia, vaginal erosion and vaginal inflammation and Secondary efficacy measures were assessment of Physical characteristics of vaginal discharge, assessment of pH of vaginal discharge and Microbiological evaluation. Assessment of Safety was done by recording the occurrence of adverse drug reactions. Results: The clinical success rates were comparable and even far better in case of Formula A group (in vaginal pain, Dyspareunia and vaginal erosion it was 100 %, in case of vaginal inflammation it was 92.655 % while in case of vaginal irritation, it was 94.767 % and vaginal pruritus, it was 87.096 %). Adverse events were mild and self limiting while it was totally absent in case of Formula A group. Conclusion: Topical Cream of Formula A is safe and effective for the treatment of mild to moderate vaginitis.

Comparison of nail lacquer clobetasol efficacy at 0,05%, 1% and 8% in nail psoriasis treatment: prospective, controlled and randomized pilot study / Comparação da eficácia do clobetasol em esmalte 0,05%, 1% e 8% no tratamento da psoríase ungueal: estudo piloto, prospectivo, controlado e randomizado

BACKGROUND: Nail psoriasis may affect up to 90% of patients with psoriasis in the course of the disease throughout their lives and it is often a therapeutic challenge to dermatologists. Topical treatments described in the literature have demonstrated variable efficacy, and unsatisfactory results have been associated to inefficient penetration of the active ingredient into the nail plate and proximal nail fold. Recently the use of clobetasol on nail lacquer vehicle has been suggested, with satisfactory results and no side effects. OBJECTIVE: To determine the efficacy and safety of clobetasol in nail lacquer vehicle in three concentrations (0.05%, 1% and 8%) in patients with nail psoriasis. METHODS: Prospective, controlled, randomized pilot study in fifteen patients with nail bed and/or nail matrix psoriasis in both hands, subdivided into three groups: A(0.05% clobetasol nail lacquer), B(1% clobetasol nail lacquer) and C(8% clobetasol nail lacquer). All groups used clobetasol nail lacquer on the left hand and base coat nail lacquer as control on the right, twice a week for 16 weeks. Clinical evaluation was done by photographic records and the NAPSI score of both treated and control hands, as well as modified NAPSI score of the most affected nail of the treated hand. RESULTS: Group C showed a statistically relevant clinical response compared to the other groups, reflected in the improvement of clinical parameters, of treated hand NAPSI score, when compared to the control hand, and modified NAPSI score of the most affected nail in the treated hand. CONCLUSION: The 8% clobetasol nail lacquer was effective and safe, and it can be considered a good option of topical therapy in the treatment of nail psoriasis.

FUNDAMENTOS: A psoríase ungueal, de difícil manejo terapêutico, pode afetar até 90% dos portadores de psoríase no transcurso da doença, ao longo de suas vidas. Os tratamentos tópicos descritos na literatura têm eficácia variável, muitas vezes com resultados insatisfatórios causados pela ineficiência da penetração da substância ativa através da placa ungueal e dobra proximal. Recentemente tem sido proposto o uso do clobetasol em veículo esmalte, demonstrando resultados satisfatórios e ausência de efeitos colaterais. OBJETIVO: Determinar a eficácia e segurança do clobetasol em veículo esmalte em três concentrações (0,05%, 1% e 8%) nos pacientes com psoríase ungueal. MÉTODOS: Estudo piloto, prospectivo, controlado e randomizado com quinze pacientes portadores de psoríase ungueal em ambas as mãos. Os pacientes foram subdivididos em três grupos: A (esmalte clobetasol 0,05%), B (esmalte de clobetasol 1%) e C (esmalte de clobetasol 8%). Os pacientes usaram esmalte de clobetasol na mão esquerda e esmalte base (sem medicação - controle) na direita, aplicandoos duas vezes por semana, por 16 semanas. Fez-se a avaliação clínica por registros fotográficos e pelos MÉTODOS: NAPSI da mão tratada e controle e NAPSI modificado da unha mais acometida da mão tratada. RESULTADOS: O grupo C apresentou de forma estatisticamente significativa a resposta clínica mais relevante, refletida na melhora dos parâmetros clínicos, do NAPSI da mão tratada comparado ao da mão controle e do NAPSI modificado da unha mais acometida da mão tratada. CONCLUSÕES: Neste estudo piloto, o esmalte de clobetasol a 8% foi eficaz e seguro, mostrando-se uma boa opção de terapêutica tópica no tratamento da psoríase ungueal.

Clobetasol para o tratamento da psoríase / Clobetasol for the treatment of psoriasis

A DOENÇA: A psoríase é uma doença sistêmica inflamatória crônica, não contagiosa, que afeta principalmente a pele, as unhas e ocasionalmente as articulações. Costuma ter um curso recidivante sendo desencadeada pelo frio, fármacos, infecções e estresse e afeta cerca de 2% da população mundial. Pode ser incapacitante tanto pelas lesões cutâneas - fator importante de dificuldade de inserção social ­ quanto pela presença da forma articular que configura a artrite psoriásica. A psoríase tem sido classificada como doença autoimune, embora sua fisiopatologia não esteja completamente esclarecida. O papel de mecanismos imunes é documentado pela presença de linfócitos T ativados e macrófagos e pela boa resposta a terapias imunossupressoras. A presença de mediadores inflamatórios também foi observada: citoquinas, fator de necrose tumoral , interferon , endotelina-1, eicosanóides, entre outros. Há uma série de comorbidades associadas à psoríase, entre elas alcoolismo, depressão, obesidade, diabete melito, hipertensão arterial, síndrome plurimetabólica, colite e artrite reumatóide. . Há estudos que relatam aumento de mortalidade por doença cardiovascular em pacientes com psoríase. Estes dados indiretos sugerem que a psoríase não está limitada à pele e que por ser uma doença crônica imuno-mediada, o aumento na morbimortalidade associado à doença possa ser explicado por um mecanismo inflamatório multissistêmico. A TECNOLOGIA: Clobetasol - Como os demais corticosteróides, o propionato de clobetasol apresenta propriedades antiinflamatória, antipruriginosa, vasoconstritora e imunossupressora. O mecanismo da atividade antiinflamatória dos esteróides tópicos em geral não está esclarecido. Contudo, acredita-se que os corticosteróides atuem induzindo a síntese da lipocortina. A lipocortina é uma proteína inibidora da atividade da fosfolipase, enzima responsável pela liberação do ácido aracdônico da membrana celular. Uma vez liberado, o ácido aracdônico é metabolizado, produzindo mediadores inflamatórios potentes, tais como prostaglandinas e leucotrienos. O propionato de clobetasol é um corticosteróide que apresenta os efeitos farmacológicos sistêmicos, tópicos e metabólicos característicos desta classe de medicamentos, sendo considerado de muito alta potência. EVIDÊNCIA CIENTÍFICA: Na base de dados Medline/Pubmed foram utilizados os termos "Psoriasis"[Mesh] AND "Therapeutics"[Mesh]. Esta busca foi restrita para estudos em humanos e do tipo metanálise, resultando em 20 artigos. Os estudos identificados nestas buscas foram avaliados individualmente, tendo sido selecionados aqueles com medicamentos tópicos disponíveis no País e com desfechos clínicos de eficácia e segurança, excluindo desfechos laboratoriais/intermediários. Desses, foram selecionadas 5 meta-análises. As exclusões ocorreram pelos seguintes motivos: um artigo em idioma alemão, dois artigos que tratavam de outras dermatoses que não psoríase e os demais por tratarem de tratamento sistêmico ou fototerapia. Foi também realizada a mesma busca, porém tendo como limite somente estudos do tipo ensaio clínico randomizado e publicados nos últimos 2 anos, período não compreendido pelas meta-análises selecionadas, resultando em 53 estudos. Desses foram excluídos 46 artigos: 21 por se tratarem de procedimentos, fármacos ou apresentações não disponíveis no Brasil, 14 por compreenderem tratamento sistêmico ou fototerapia, 6 por técnicas ou tratamentos alternativos, 2 por contemplarem doenças outras que não psoríase, 1 por abordar tema não relevante para a análise e 2 por apresentar delineamento confuso e desfechos não objetivos ou histopatológicos, restando então 7 estudos que foram analisados. A busca na Cochrane Database foi realizada com os termos "Psoriasis" and "Topical Treatment" e originou 3 revisões, 2 foram excluídas por se tratarem de outras formas de psoríase específicas (gutatta e pustulose palmo-plantar). Foi incluída uma revisão da Cochrane Database. DELIBERAÇÃO FINAL: Os membros da CONITEC presentes na 6ª reunião ordinária do dia 05/07/2012, por unanimidade, ratificaram a deliberação de recomendar a incorporação do medicamento clobetasol 0,05% creme conforme Protocolo Clínico e Diretrizes Terapêuticas do Ministério da Saúde para o tratamento da Psoríase. O Conselho Nacional de Saúde se absteve de votar conforme posição acordada pelo Plenário do CNS. DECISÃO: PORTARIA SCTIE/MS N° 33, de 27 de setembro de 2012 - Torna pública a decisão de incorporar o medicamento Clobetasol para o tratamento da Psoríase no Sistema Único de Saúde (SUS).

Psoriasis ungueal: experiencia con el tratamiento combinado de clobetasol al 8 por ciento en laca ungueal y calcipotriol / Combined clobetasol and calcipotriol treatment for nail psoriasis

La psoriasis ungueal es un problema común en los pacientes psoriáticos, con una incidencia de vida de 90%. A pesar de su alta incidencia y del gran impacto que produce en la calidad de vida, ha sido poco estudiada y el tratamiento óptimo aún no está bien dilucidado. Los corticoides tópicos y los análogos de la vitamina D son las terapias más usadas, pero no existe un esquema estándar para su uso. La combinación de estos agentes se ha estudiado en los últimos años para pacientes con afectación de la matriz y del lecho ungueal, mostrando muy buenos resultados. El caso que presentamos demuestra la sinergia entre estos agentes.

Nail psoriasis is a common problem among psoriatic patients, with a lifetime incidence of 90%. Despite its high incidence and severe impact on the quality of life, it has not been fully studied and the optimal treatment is still unclear. Topical glucocorticosteroids and vitamin D analogues are the most used therapies, but there is no standard therapeutic regimen for their use. The combination of both of these agents has been studied during the last years for the treatment of patients with matrix and bed nail compromise, showing very good results. The case that we present shows the synergy between these agents.

Treatment of perniosis with oral pentoxyfylline in comparison with oral prednisolone plus topical clobetasol ointment in Iraqi patients

To evaluate the effectiveness and safety of pentoxyfylline in treatment of perniosis in comparison with prednisolone plus topical clobetasol ointment. This is an open comparative therapeutic trial conducted in the Department of Dermatology, Baghdad Teaching Hospital, Baghdad, Iraq between January and March 2008. Forty patients with perniosis were enrolled in this study, and divided randomly into 2 equal groups, according to the sort of treatment. Group A comprised patients who received oral prednisolone 0.5 mg/kg in 2 divided doses, and topical clobetasol ointment for 2 weeks. Group B comprised patients who received pentoxyfylline tablet 1200 mg/day in 3 divided doses for 2 weeks. Detailed history and full clinical examination were carried out for each case, regarding all relevant points related to the disease. The age of patients ranged from 5-60 mean +/- SD 22 +/- 6.2 years, with 31 females and 9 males with a female to male ratio of 3.5:1. All patients did not receive any treatment before the study. In group A, 11 patients completed the treatment course, and only 3 27.2% patients showed good improvement and complete cure after 2 weeks. In group B, 9 patients completed the regime, and 5 55.5% patients showed good improvement, in which symptoms disappeared and lesions resolved after 2 weeks. Pentoxyfylline was shown to be an effective and safe drug for treatment of perniosis, and superior to oral plus topical glucocorticoids p < 0.05.

Comparison of clinical efficacy of topical tazarotene 0.1% cream with topical clobetasol propionate 0.05% cream in chronic plaque psoriasis: a double-blind, randomized, right-left comparison study.

BACKGROUND: No controlled data is available till date comparing topical tazarotene and clobetasol in Indian psoriatic patients. OBJECTIVE: The aim was to compare the clinical efficacy of 12 weeks of once-daily tazarotene 0.1% cream with that of once-daily clobetasol propionate 0.05% cream in the treatment of patients with chronic plaque psoriasis. METHODS: About 36 patients with bilaterally symmetrical lesions were enrolled in this double-blind randomized controlled study. A left-right randomized study was conducted. RESULTS: Clobetasol cream was better than tazarotene cream in reducing the erythema throughout the treatment period with statistically significant differences favoring clobetasol at weeks 2, 4, 6 and 8 ( P <0.05). Tazarotene was better in reducing the induration at weeks 2 ( P <0.05), 4, 10 and 12. Clobetasol cream was better in reducing the scaling throughout the treatment period with statistically significant differences favoring clobetasol over the entire treatment period. Treatment success rate was 100% with clobetasol and 88% with tazarotene at the end of week 12 with clobetasol achieving 100% success rate at the end of week 6. Treatment with tazarotene resulted in uniform reduction of plaque elevation and was not associated with the development of hot spots. CONCLUSION: Topical tazarotene 0.1% cream is less effective than topical clobetasol propionate 0.05% cream in the treatment of plaque psoriasis. It has more effect on induration than on erythema and scaling of psoriatic lesions.

Evaluación clínica del uso de un champú con clobetasol al 0, 05 por ciento en el tratamiento de la dermatitis seborreica moderada y severa del cuero cabelludo / Effectiveness and safety of a clobetasol shampoo formulation in patients with moderate and severe seborrheic dermatitis

La dermatitis seborreica del cuero cabelludo va desde una pitiriasis simple difusa a costras eritematoescamosas. La inflamación y el Pytirosporum ovale juegan un papel importante, por lo que los corticoides tópicos resultan en general exitosos. En el presente estudio se analizan la efectividad y seguridad del uso de clobetasol al 0,05 por ciento en formulación champú, aplicado durante 15 días, por 27 pacientes con dermatitis seborreica moderada o severa. La efectividad fue evaluada a través de analizar prurito, descamación y eritema. La seguridad se evaluó constatando irritación local, eritema y descamación en áreas vecinas. Esta formulación es altamente efectiva, con desaparición del prurito en 92 por ciento de los pacientes a los 15 días de tratamiento. Similar situación ocurre con la disminución del eritema. Respecto a seguridad, en un 4 por ciento de los pacientes advirtió irritación local.

Seborrheic dermatitis of the scalp can manifest itself as anything from a simple diffused pityriasis to erythematous plaques. In all of these, the degree of inflammation and the presence os Pityrosporum ovale play an important role. We present an analysis of the effectiveness and safety of clobetasol shampoo formulation, applied daily for 15 minutes during 15 days, in 27 patients suffering from moderate or severe seborrheic dermatitis. Effectiveness was evaluated through analyzed pruritus, scaling, and erythema. Safety was evaluated by verifying irritation in the area of application, erythema and scaling of surrounding areas. Results were highly effective: pruritus disappeared in 92 percent of patients after 15 days, and erythema decreased in similar terms. Only 4 percent of patients presented local irritation.

Clobetasol propionate solid lipid nanoparticles cream for effective treatment of eczema: formulation and clinical implications.

In the present study clobetasol propionate (Cp) was loaded as solid lipid nanoparticles (SLN), incorporated it in suitable cream base and evaluated in vitro and its performance clinically against equivalent marketed formulation. Cp was incorporated into SLN by high-pressure homogenization technique and characterized for mean particle size, surface morphology and per cent drug entrapment. Drug permeation and skin uptake studies from Cp creams were carried out in a validated Franz static diffusion cell across human cadaver skin (HCS). Sixteen chronic eczema patients were enrolled in a controlled double blind clinical trial. Optimized Cp-SLN was smooth and spherical under scanning electron microscopy; with average particle size of 177 nm and per cent drug entrapment of 92.05%. In vitro permeation studies revealed lower mean flux value and higher skin uptake of Cp from Cp-SLN cream compared to marketed drug cream. Both formulations were found to be responsive to manifestations of chronic eczema, while Cp-SLN cream prepared in this investigation registered significant improvement in therapeutic response (1.9 fold; inflammation, 1.2 fold; itching) in terms of per cent reduction in degree of inflammation and itching against marketed cream. Further clinical trials are required to ascertain the efficiency of the present formulation.

Comparative study of the efficacy of topical corticosteroid: five locally made and one brand name creams.

The aim of this study was to evaluate the efficacy of 5 locally made clobetasol propionate creams compared with a brand name product. The study was divided into 3 parts 1) pharmacological study, 2) vasoconstriction test, and 3) double blind clinical trial. The results showed that the pharmacological properties of the locally made products were not different from the brand name product. Product C and D could diffuse through cellulose acetate membrane 3 fold more than the brand name product. Product D and E caused less vasoconstriction than the brand name product. This double blind study showed that all locally made products could improve psoriasis to the same extent as the brand name product, but there was more recurrence of psoriasis while using all the locally made products. It was concluded that locally made products were as effective as the brand name product in the treatment of psoriasis evaluated over a 2 week peroid, but more recurrence was observed with locally made products.
