Antecedentes da Invenção Background of the Invention

Diabetes Mellitus /(DM) é uma condição metabólica caracterizada por uma elevada e constante concentração de glicose no sangue, que contribui para o desenvolvimento de neuropatia periférica, e de complicações macro e microvasculares. O aumento da incidência e prevalência da DM está associado, entre outros fatores, ao envelhecimento e acredita-se que afete 6% da população mundial.  Diabetes Mellitus / (DM) is a metabolic condition characterized by a high and constant blood glucose concentration, which contributes to the development of peripheral neuropathy, as well as macro and microvascular complications. The increased incidence and prevalence of DM is associated, among other factors, with aging and is believed to affect 6% of the world's population.

Os danos neurológicos, tanto dos sistemas periféricos quanto autónomos, ocorrem em ambos os tipos de DM (tipos I ou II), estando também relacionados aos anos de prevalência e controle da doença. Estima-se que 60% dos pacientes diabéticos apresentem algum tipo de dano neurológico. Os danos neurológicos causam insensibilidade e perda da capacidade de discernir calor, frio e dor. Assim, cortes pequenos, ou qualquer outro tipo de dano físico, se não tratado, pode levar a infecções sérias que podem resultar em amputação dos membros.  Neurological damage in both peripheral and autonomic systems occurs in both types of DM (types I or II), and is also related to years of disease prevalence and control. It is estimated that 60% of diabetic patients have some type of neurological damage. Neurological damage causes insensitivity and loss of ability to discern heat, cold and pain. Thus, small cuts, or any other type of physical damage, if left untreated, can lead to serious infections that can result in limb amputation.

Além dos danos neurológicos, os danos à circulação comprometem a eficiente circulação de sangue. Ocorre um estreitamento das artérias, que leva a um fluxo sanguíneo menor, em especial nas regiões inferiores, como pernas e pés. Assim, um paciente diabético é mais propenso a infecções pela incapacidade de sentir desconforto e, também, devido a uma circulação pobre, há um fluxo de nutrientes e oxigénio menor, dificultando assim a cicatrização das feridas, que acabam por se desenvolver em úlceras. De acordo com a "Classificação de Wagner", as úlceras em pés de pacientes diabéticos são dividas nos seguintes graus: In addition to neurological damage, damage to circulation compromises efficient blood circulation. Narrowing of the arteries leads to less blood flow, especially in the lower regions such as the legs and foot. Thus, a diabetic patient is more prone to infections due to the inability to feel discomfort and also due to poor circulation, there is a lower nutrient and oxygen flow, thus making it difficult to heal the wounds that eventually develop into ulcers. According to the "Wagner Classification", foot ulcers of diabetic patients are divided into the following degrees:

Grau 0 - Risco elevado, ausência de úlcera;  Grade 0 - High risk, absence of ulcer;

Grau 1 - Úlcera superficial, não infectado em termos clínicos;  Grade 1 - Superficial ulcer, not clinically infected;

Grau 2 - Úlcera profunda ± celulite, ausência de abcesso ou osteomielite; Grau 3 - Úlcera profunda com osteomielite ou formação de abcesso;  Grade 2 - Deep ulcer ± cellulitis, absence of abscess or osteomyelitis; Grade 3 - Deep ulcer with osteomyelitis or abscess formation;

Grau 4 - Gangrena localizada; e  Grade 4 - Localized Gangrene; and

Grau 5 - Gangrena em todo o pé.  Grade 5 - Gangrene all over the foot.

Dessa forma, os tratamentos visando a melhora destas úlceras variam conforme o grau de dano tecidual. Para os estágios iniciais, composições que atuam como agentes hidratantes são mais indicados, enquanto composições com agentes cicatrizantes e/ou regenerativos são mais indicadas nos casos mais graves. Assim, é uma necessidade para o paciente diabético uma composição que seja capaz de tratar essas úlceras, em qualquer estágio, agregando qualidade de vida ao processo de envelhecimento do paciente diabético,  Thus, treatments aimed at improving these ulcers vary according to the degree of tissue damage. For the early stages, compositions that act as moisturizing agents are more indicated, while compositions with healing and / or regenerative agents are more indicated in the most severe cases. Thus, it is a necessity for the diabetic patient a composition that is capable of treating these ulcers at any stage, adding quality of life to the aging process of the diabetic patient,

Tais componentes atuam como agentes hidratantes e emolientes, proporcionando a retenção das ceramidas da pele e a restauração da barreira lipídica. Atuando em conjunto com os fatores naturais de hidratação da pele, esses componentes restauram o equilíbrio lipídico, proporcionando um ambiente regenerativo para as células. A concentração da combinação dos agentes hidratantes varia de 0,5 a 5,0% p/p. Veículo farmaceuticamente aceitável / Componentes adicionais Another class of compounds optionally used in the combination of moisturizing agents are essential fatty acids. For the purposes of the present invention, essential fatty acids are fatty acids of up to 22 carbon atoms and 0 to 5 unsaturated. Non-limiting examples of these acids include linoleic (18: 2) and linolenic (18: 3) acids. Such components act as moisturizing and emollient agents, providing retention of skin ceramides and restoration of the lipid barrier. Acting in conjunction with the skin's natural moisturizing factors, these components restore lipid balance, providing a regenerative environment for cells. The concentration of the moisturizing agent combination ranges from 0.5 to 5.0% w / w. Pharmaceutically Acceptable Vehicle / Additional Components
