Abstract

A presente invenção refere-se a um curativo médico compreendendo superfície adesiva porosa e uma almofada contendo um fungicida, para tratar doenças fúngicas da pele e de anexos da pele, como pelos e unhas, entretanto curativo para tratar doenças fúngicas, não limita o invento, podendo o mesmo ser apropriado para tratar infecções ou prevenir infecções causadas por outros microorganismos patogênicos como bactérias e ainda como adjuvante na cicatrização de feridas. O curativo é de fácil aplicação e estando fixado sobre o tecido infectado, a almofada é umedecida com gotas de água para iniciar o tratamento, sem a necessidade diária de substituir o curativo, apenas umedecendo a almofada ativa por um período a cada 24 horas. Uma vantagem da patente de invenção é o fato do liquido usado ser água destilada, potável ou até soro fisiológico e a bandagem fungicida ativa é preferivelmente selecionada de algodão de um sal sólido de um agente fungicida como o tereftalato de potássio, que se mostra como princípio ativo único ou em formulações para combater doenças fúngicas.

The present invention relates to a medical dressing comprising a porous adhesive surface and a pad containing a fungicide, for treating fungal diseases of the skin and skin appendages, such as hair and nails, however a dressing for treating fungal diseases, does not limit the invention, it may be suitable for treating infections or preventing infections caused by other pathogenic microorganisms such as bacteria and also as an adjuvant in wound healing. The dressing is easy to apply and once it is fixed on the infected tissue, the pad is moistened with drops of water to start the treatment, without the daily need to replace the dressing, just moistening the active pad for a period every 24 hours. An advantage of the patent is the fact that the liquid used is distilled, potable or even saline water and the active fungicide bandage is preferably selected from cotton of a solid salt of a fungicidal agent such as potassium terephthalate, which is shown as a principle single active ingredient or in formulations to combat fungal diseases.

[004] Medicamentos fungicidas com ação por via oral para tratar doenças da pele e dos anexos da pele, podem apresentar desconforto para o paciente devido aos efeitos colaterais causados pela toxicidade de principio ativo ou da formulação medicamentosa, já os medicamentos de uso tópico como soluções, pomadas e cremes também possuem limitações tecnológicas relacionadas com a aplicação e tempo permanência do produto sobre o tecido em tratamento, dessa forma a cura da doença fúngica se torna um processo desconfortável e de tempo longo o que causa muito desconforto para os pacientes.[004] Fungicidal drugs with oral action to treat diseases of the skin and skin adnexa may present discomfort to the patient due to the side effects caused by the toxicity of the active ingredient or drug formulation, whereas topical drugs as solutions , ointments and creams also have technological limitations related to the application and time permanence of the product on the tissue under treatment, thus the cure of the fungal disease becomes an uncomfortable process and takes a long time, which causes a lot of discomfort for the patients.

[005] O objetivo da presente patente de invenção é propiciar o tratamento de doenças fúngicas da pele e de anexos da pele sem os problemas técnicos de toxicidades inerentes aos remédios administrados por via ora ou injetáveis, bem como o pouco tempo de duração e ação dos fungicidas de uso tópicos na forma de solução liquida, cremes ou pomadas que necessitam de várias aplicações durante o dia.[005] The purpose of this invention patent is to provide the treatment of fungal diseases of the skin and skin appendages without the technical problems of toxicities inherent to drugs administered orally or injectables, as well as the short duration and action of Topical fungicides in the form of liquid solutions, creams or ointments that require several applications during the day.

[006] A presente patente de invenção se refere a um curativo na forma de bandagem compreendido por um material na forma de fita adesiva contendo uma almofada impregnada com um agente fungicida para tratar doenças fúngicas da pele e anexos da pele.[006] The present patent relates to a bandage in the form of a bandage comprised of a material in the form of adhesive tape containing a pad impregnated with a fungicidal agent to treat fungal diseases of the skin and skin appendages.

[007] Um detalhe em particular da presente patente se refere ao fato que a fita adesiva permite a passagem de líquidos para solubilizar o agente fungicida compreendido na almofada da bandagem do curativo para tratar doenças fúngicas.[007] A particular detail of the present patent refers to the fact that the adhesive tape allows the passage of liquids to solubilize the fungicidal agent comprised in the bandage pad of the dressing to treat fungal diseases.

[008] Uma vantagem da patente se refere ao fato de que o principio ativo fica em contato direto com o tecido doente, agindo continuamente por vários dias no tratamento da doença, sem a necessidade de novas aplicações do remédio, tornando um produto de baixo custo e mais eficiente.[008] An advantage of the patent refers to the fact that the active principle is in direct contact with the diseased tissue, acting continuously for several days in the treatment of the disease, without the need for new drug applications, making it a low-cost product and more efficient.
