- composition of antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention is a compound comprising an additive based on Polyhexamethylene Biguanide (PHMB), which associated with antimicrobials and/or antibiotics in general, explains the mechanism of action that nullifies the protection of bacteria to drugs, allowing drugs to act normally.
- PHMB Polyhexamethylene Biguanide
- the compound proposed here has a bactericidal property that begins with a rapid attraction of the cationic PHMB on the negatively charged bacterial surface causing a failure in the bacterial cell defense mechanism and the rupture of the cell wall.
- PHMB is attracted to the cytoplasmic membrane where it causes the loss of low molecular weight substances, such as Potassium and Calcium ions, and the inhibition of enzymes responsible for membrane binding, such as ATPase.
- the subsequent large disruption of the cytoplasmic membrane can then lead to the loss of macromolecular substances such as nucleotides and the precipitation of cellular substances. Thus destroying bacteria and preventing their proliferation. This effect is multiplied up to four times when PHMB is combined with antibacterials.
- PHMB Polyhexamethylene Biguanide
- Polymeric Biguanide is not toxic on living tissue, is highly soluble in water, is free of odor, color and taste and non-teratogenic (Ames test negative), is very active in low doses, it has low systemic toxicity (proven in broilers), is adsorbed by the gastrointestinal tract and is rapidly and completely eliminated in the urine.
- the composition called , antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention deals with the concomitant use of polymeric biguanide PHMB at 20%, used in proportion in the basic dose of 20 ppm, in association with antibiotics and/or antibacterials, these in the dose recommended by the manufacturers.
- the antibiotics and/or antibacterials used can be any one indicated in human and veterinary medicine for the various bacterial infections and approved by Organs competent bodies such as ANVISA and MAPA.
- the dosage of antibiotics and/or antibacterials used in association with PHMB is determined by the objective application obtained according to the antibiogram of the causal agent of the disease to be fought, however, the ideal dose of the association can be established in advance for each bacteria .
- Polymeric Biguanide PHMB Polyhexamethylene Biguanide
- IPEL and ArchQuimica Polyhexamethylene Biguanide
- This compound when used in association with antibacterials and/or antibiotics in the treatment of infections caused by bacteria in animals, dramatically reduces the MIC (Minimum Inhibitory Concentration).
- the MIC reduction is up to 4 times or more depending on the antibacterial used and the bacteria challenged. In the "I ⁇ VITRO" tests, the antibacterials and polymeric biguanide individually do not have the same result compared to those obtained when used in combination.
- composition described here and its method of obtaining it is the result of much research to find a way to revitalize existing drugs that was not a new antibiotic but a substance that could nullify the protection created by the bacteria to protect itself from the action of the medications in use, weakening their resistance. .
- a substance to be used as a medicine must have specific characteristics. Have low or no toxicity in the dose used for animals and humans; be soluble in water to be consumed along with drugs in oral treatment and adsorbed by the gastrointestinal tract (Systemic action); be free of taste and odor; be very active against Gram-negative and Gram-positive bacteria at low doses; have no systemic toxicity; eliminated completely in the urine; it must be economically viable to be compatible with treatment costs for both animals and humans. These characteristics were found in Polymeric Biguanide, a fact that gave rise to the 'VITRO' tests, which confirmed the synergistic action with antibacterials versus pathogenic bacteria.
- FIG. 3 shows the action of the PHMB compound attacking Gram-negative bacteria, which has an extra layer of membrane, outside the cell wall.
- PHMB attacks the cell, binding to the membrane: PHMB being a positively charged molecule, while the cell wall is negatively charged.
- the PHMB attracts cell fragments.
- PHMB travels through the peptidoglycan layer, like water through a filter, to attract the inner membrane.
- the cell wall begins to "sag” and its protective layers are "splintered", causing the cytoplasm to leak and the cell to collapse leaving behind only a skeleton. This rapid electrostatic destruction occurs in the same way with Gram-positive bacteria that doesn't have an outer membrane.
- PHMB attracts, binds and annihilates.
- the technology that reduces bacterial resistance object of this invention, consists of the possible associations of the PHMB with various drugs whose interest and responsibility is of the manufacturers of veterinary and/or human products that must formulate the new products in accordance with current laws and register them at MAPA or at ANVISA. Only after duly registered can they be sold and used.
- the antibacterial composition that reduces the resistance of bacteria is a composition of a solution of polymeric biguanide PHMB at 20%, or used in a proportion of at a dose of 20 ppm in mixture, in association with antibiotics and /or bactericides in the minimum specific dose for the desired objective application MIC, being a solution composition for oral administration for veterinary or human use.
- antibiotics and/or bactericides could be: penicillin for diseases respiratory diseases, ciprofloxacin for urinary diseases, sulfa+trimethoprim for enteric diseases, with the known specifications of each application and use indicated in each case, and can also be any antibiotics and/or bactericides already known suitable for each disease or battery to be fought.
- the dosage of antibiotics and/or bactericides is determined by the objective application obtained according to the antibiogram of the disease to be fought, or through the antibacterial of the bacteria or disease to be fought.
- the antibacterial composition that reduces the resistance of bacteria consists of mixing by stirring until dilution of 50 to 250 rpm, at room temperature, of the 20% solution of polymeric biguanide PHMB (Polyhexamethylene Biguanide) in solution, with antibacterials and/or antibiotics in the proportion determined by the MIC (Minimum Inhibitory Concentration) for each disease to be fought.
- PHMB Polyhexamethylene Biguanide
- the Antimicrobial Activity test was performed for the antibiotic Evanflox-50 (50% Ciprofloxacin) and the additive IPEL BHD 255 (Polymeric Biguanide 20% PHMB) against Salmonellacholeraesuis ATCC 10708.

Este novo composto com o uso do PHMB propicia a potencialização dos antibacterianos restaurando as suas atividades originais e tomando desnecessário o desenvolvimento imediato de novos medicamentos. As diversas combinações que podem ser obtidas com a associação do PHMB aos antibacterianos reduzem as doses de antibióticos utilizadas nos tratamentos com consequências técnicas e económicas consideráveis beneficiando toda a cadeia produtiva e a saúde humana. O beneficio ao meio ambiente também se toma evidente se levarmos em conta a quantidade de antibióticos que vão ao solo com as fezes dos animais em tratamento. [001] This report deals with the detailed description accompanied by illustrative figures of a new composition of an antibacterial association that reduces the resistance of bacteria to drugs in use and its method of obtaining it. The new way of obtaining and using it implies the association of the compound Polyhexamethylene Biguanide (PHMB), better known as Polymeric Biguanide, with the various antibiotics or antibacterials used in the treatment of infections caused by bacteria. The association of PHMB with any antibacterial used results in the potentiation of both by a synergistic effect, drastically reducing the Minimum Inhibitory Concentration (MIC), in a clear demonstration of the potent effectiveness against bacteria. This new compound with the use of PHMB provides the potentiation of antibacterials, restoring their original activities and making the immediate development of new drugs unnecessary. The various combinations that can be obtained with the association of PHMB with antibacterials reduce the doses of antibiotics used in treatments with considerable technical and economic consequences, benefiting the entire production chain and human health. The benefit to the environment is also evident if we take into account the amount of antibiotics that go into the soil with the feces of animals undergoing treatment.

OBJETIVO DA PRESENTE INVENÇÃO PURPOSE OF THE PRESENT INVENTION
[003] A composição de associação antibacteriana redutora da resistência das bactérias e método de obtenção, objeto da presente invenção, tem por objetivo oferecer ao mercado pertinente farmacêutico, veterinário e humano, uma nova substância coadjuvante em associação com medicamentos, que aumenta a eficiência dos antibacterianos e/ou antibióticos conhecidos, com segurança para os indivíduos tratados, anulando a proteção criada pelas bactérias para se proteger da ação dos medicamentos conhecidos, e dessa forma poder resolver os problemas de bactérias resistentes aos mesmos, sem a necessidade urgente do desenvolvimento de novos medicamentos. [003] The composition of antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention, aims to to offer to the relevant pharmaceutical, veterinary and human market a new supporting substance in association with medicines, which increases the efficiency of known antibacterials and/or antibiotics, with safety for treated individuals, nullifying the protection created by the bacteria to protect themselves from the action of known drugs, and thus be able to solve the problems of bacteria resistant to them, without the urgent need to develop new drugs.
JUSTIFICATIVA E PROBLEMA A SER RESOLVIDO JUSTIFICATION AND PROBLEM TO BE SOLVED
[004] É de conhecimento, no âmbito da medicina veterinária e humana, o crescente aumento da resistência bacteriana aos medicamentos, cujas causas são imputadas ao mau uso, ou uso indiscriminado, ou seu uso prolongado, especialmente em baixas dosagens como melhoradores da eficiência alimentar dos animais de produção e em outros casos. A resistência aos antimicrobianos já é um problema de saúde pública na esfera global. A grande preocupação da resistência das bactérias aos medicamentos afeta a saúde humana e é uma das causas de alta mortalidade por infecções hospitalares pelas Superbactérias. A proposta desta invenção é tomar os medicamentos existentes, mais eficientes e eficazes com uso de doses bem menores, e com isto também evitar a poluição do solo com quantidades expressivas de antibióticos excretadas com as fezes dos animais durante os tratamentos. Mais ainda para minimizar o risco de resíduos de antibióticos nos produtos de origem animal usados como alimentos pelos seres humanos, como ovos, carnes de aves, suínos e bovinos, eventualmente vindos a ser consumidos quando em fase de tratamento destes contra as infecções. Além dos benefícios para a saúde e o bem estar dos animais e dos seres humano deve-se levar em conta os milhões em divisas economizados na importação de antibióticos e quimioterápicos. [004] It is known, in the scope of veterinary and human medicine, the increasing increase in bacterial resistance to drugs, whose causes are attributed to misuse, or indiscriminate use, or their prolonged use, especially at low doses as food efficiency improvers production animals and in other cases. Antimicrobial resistance is already a global public health problem. The great concern of bacterial resistance to drugs affects human health and is one of the causes of high mortality from hospital infections caused by Superbacteria. The purpose of this invention is to take existing drugs, more efficient and effective with the use of much lower doses, and with this also avoid soil pollution with expressive amounts of antibiotics excreted with the feces of animals during treatments. Even more so to minimize the risk of antibiotic residues in animal products used as food by humans, such as eggs, poultry, pork and beef, eventually being consumed when they are being treated against infections. In addition to the benefits for the health and well-being of animals and humans, the millions in foreign exchange saved on the import of antibiotics and chemotherapy must be taken into account.
[005] É importante considerar também a redução dos custos dos tratamentos terapêuticos nos animais, e porque não também dos humanos, promovendo uma economia que beneficia toda a cadeia produtiva e os consumidores, trazendo assim um grande benefício para a humanidade. [006] A Invenção aqui proposta e o seu método de obtenção possibilitam a preparação dos mais diversos e variados compostos antibacterianos associados ao PHMB, aumentando a atividade bactericida em até quatro vezes da dose padrão dos próprios antibacterianos. As vantagens são a grande redução de quantidades de medicamento e utilizados na terapia das infecçôes causadas por bactéria e a consequente redução do risco de resíduos de antibióticos nas carnes e ovos de animais tratados com medicamentos e consumidos pelos seres humanos. Também a drástica redução da poluição do solo onde toneladas de medicamentos são excretadas comas fezes dos animais em tratamentos contra as infecçôes. O consequente controle da resistência bacteriana aos medicamentos e o resgate dos antibacterianos e antibióticos, comprovadamente inativos versus as bactérias resistentes e que com o uso associado do PHMB readquirem a sua importância como opções para a terapia veterinária e humana. A influência direta na redução nos custos dos medicamentos e dos tratamentos, beneficiando a população. A redução de óbitos por infecçôes hospitalares causadas pelas chamadas Superbactérias (Infecçôes Hospitalares). [005] It is also important to consider the reduction of costs of therapeutic treatments in animals, and why not also in humans, promoting an economy that benefits the entire production chain and consumers, thus bringing a great benefit to humanity. [006] The invention proposed here and its method of obtaining it enable the preparation of the most diverse and varied antibacterial compounds associated with PHMB, increasing the bactericidal activity in up to four times the standard dose of the antibacterials themselves. The advantages are the great reduction in the quantities of medication used in the treatment of infections caused by bacteria and the consequent reduction in the risk of antibiotic residues in the meat and eggs of animals treated with medication and consumed by human beings. Also the drastic reduction of soil pollution where tons of medicines are excreted with the feces of animals in treatments against infections. The consequent control of bacterial resistance to drugs and the rescue of antibacterials and antibiotics, proven to be inactive versus resistant bacteria and which, with the associated use of PHMB, regain their importance as options for veterinary and human therapy. The direct influence on reducing the costs of medicines and treatments, benefiting the population. The reduction of deaths from hospital infections caused by the so-called Superbacteria (Hospital Infections).

GENERAL DESCRIPTION OF THE INVENTION:
[024] A composição de associação antibacteriana redutora da resistência das bactérias e método de obtenção, objeto da presente invenção, consiste no uso como aditivo de Polihexametileno Biguanida (PHMB), cuja formula molecular é (CeH17N5)n, que associado aos antibacterianos e/ou antibióticos explicita uma ação sinérgica aumentando a eficácia de ambos. Esta substância é um polímero mais comumente utilizado como desinfetante e anti-séptico, o qual apresenta as propriedades físico-químicas de: alta solubilidade em água, baixa volatilidade, baixa corrosividade, PH neutro, ausência de sabor e cor, boa estabilidade térmica, boa adsorção gastrointestinal (facilidade para uso oral), baixa toxicidade em mamíferos e meio ambiente, e com uma característica especial de amplo espectro de atuação sobre bactérias Gram-negativas, Gram- positivas, vírus, fungos e microrganismos resistentes aos antibióticos. [024] The composition of antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention, consists in the use as an additive of Polyhexamethylene Biguanide (PHMB), whose molecular formula is (C and H 17 N 5 )n, which associated with antibacterials and/or antibiotics shows a synergistic action increasing the effectiveness of both. This substance is a polymer most commonly used as a disinfectant and antiseptic, which has the physicochemical properties of: high water solubility, low volatility, low corrosivity, neutral pH, lack of flavor and color, good thermal stability, good gastrointestinal adsorption (easy for oral use), low toxicity in mammals and the environment, and with a special feature of broad spectrum action on Gram-negative, Gram-positive bacteria, viruses, fungi and antibiotic-resistant microorganisms.
[025] As vantagens de utilizar o Polihexametileno Biguanida (PHMB), associada aos antibacterianos e/ou antibióticos são: O aumento da ação antibacteriana e de amplo espectro, associada à facilidade de manejo para os tratamentos por via oral, a baixa toxicidade, a facilidade de manuseio sem risco para os operadores, assim como o mecanismo de ação diferenciado sobre bactérias permite a associação com qualquer antimicrobianos e/ou antibióticos em geral. [025] The advantages of using Polyhexamethylene Biguanide (PHMB), associated with antibacterials and/or antibiotics are: Increased antibacterial and broad-spectrum action, associated with ease of handling for oral treatments, low toxicity, ease of handling without risk for operators, as well as the differentiated mechanism of action on bacteria allows the association with any antimicrobials and/or antibiotics in general.
[026] A composição de associação antibacteriana redutora da resistência das bactérias e método de obtenção, objeto da presente invenção, é um composto compreendendo um aditivo a base de Polihexametileno Biguanida (PHMB), que associado aos antimicrobianos e/ou antibióticos em geral, explicita o mecanismo de ação que anula a proteção das bactérias aos medicamentos, permitindo aos medicamentos agirem normalmente. [026] The composition of antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention, is a compound comprising an additive based on Polyhexamethylene Biguanide (PHMB), which associated with antimicrobials and/or antibiotics in general, explains the mechanism of action that nullifies the protection of bacteria to drugs, allowing drugs to act normally.
[027] Este mecanismo, próprio das Biguanidas, que são polímeros de cargas positivas sequenciais, que reagem com as cargas negativas dos fosfolipídeos, constituintes da membrana celular externa, protetora das bactérias, levando a ruptura da mesma e consequente saída do Citoplasma com a perda de todo seu material com capacidade de mutação e replicação e ao mesmo tempo, quando associado aos antibacterianos, aumenta a atividade de ambos. Esta ação é bactericida e de efeito sinérgico. [027] This mechanism, typical of Biguanides, which are sequentially positively charged polymers, which react with the negative charges of phospholipids, constituents of the outer cell membrane, protective of bacteria, leading to its rupture and consequent release of the Cytoplasm with loss at all its material with the ability to mutate and replicate and at the same time, when associated with antibacterials, increases the activity of both. This action is bactericidal and synergistic.
[028] Assim, o composto aqui proposto, possui uma propriedade bactericida que começa com uma rápida atração do PHMB catiônico na superfície bacteriana negativamente carregada provocando uma falha no mecanismo de defesa da célula bacteriana e a ruptura da parede celular. O PHMB é atraído para a membrana citoplasmática onde causa a perda de substâncias de baixo peso molecular, tais como íons de Potássio, Cálcio e a inibição de enzimas responsáveis pela união da membrana, tais como o ATPase. A grande ruptura subsequente da membrana citoplasmática pode então levar a perda de substâncias macromoleculares como os nucleotídeos e a precipitação de substâncias celulares. Dessa forma destruindo as bactérias e impedindo sua proliferação. Este efeito é multiplicado até quatro vezes quando o PHMB é associado aos antibacterianos. Este efeito é denominado de Sinergismo e está comprovado no “Ensaio de Atividade antimicrobiana para o antibiótico Evanflox-50 (Ciprofloxacina a 50%)” associado ao aditivo IPEL BHD-255 (biguanida polimérica a20%) contra a Bactéria Salmonella cholerasuis ATCC- 10708. Ensaio este realizado no laboratório do Centro Pluridisciplinar de Pesquisas Químicas, Biológicas e Agrícolas da UNICAMP. O ensaio mostra a atividade dos dois elementos em separados e a atividade de uma blenda dos dois. [028] Thus, the compound proposed here has a bactericidal property that begins with a rapid attraction of the cationic PHMB on the negatively charged bacterial surface causing a failure in the bacterial cell defense mechanism and the rupture of the cell wall. PHMB is attracted to the cytoplasmic membrane where it causes the loss of low molecular weight substances, such as Potassium and Calcium ions, and the inhibition of enzymes responsible for membrane binding, such as ATPase. The subsequent large disruption of the cytoplasmic membrane can then lead to the loss of macromolecular substances such as nucleotides and the precipitation of cellular substances. Thus destroying bacteria and preventing their proliferation. This effect is multiplied up to four times when PHMB is combined with antibacterials. This effect is called Synergism and is proven in the “Antimicrobial Activity Assay for the antibiotic Evanflox-50 (50% Ciprofloxacin)” associated with the additive IPEL BHD-255 (20%) polymeric biguanide against the bacteria Salmonella cholerasuis ATCC-10708. This essay was carried out in the laboratory of the Pluridisciplinary Center for Chemical, Biological and Agricultural Research at UNICAMP. The essay shows the activity of the two elements separately and the activity of a blend of the two.

[030] A composição denominada , associação antibacteríana redutora da resistência das bactérias e método de obtenção, objeto da presente invenção, trata do uso concomitante de Biguanida polimérica PHMB a 20%, utilizada em proporção na dose básica de 20 ppm, em associação com antibióticos e/ou antibacterianos, estes na dose recomendada pelos fabricantes. Os antibióticos e/ou antibacterianos utilizados podem ser qualquer um indicado na medicina humana e veterinária para as diversas infecções bacterianas e aprovados pelos órgãos competentes como a ANVISA e MAPA. A dosagem dos antibióticos e/ou antibacterianos utilizados em associação com o PHMB é determinada pela aplicação objetiva obtida de acordo com o antibiograma do agente causal da doença a ser combatida, entretanto pode-se estabelecer a dose ideal da associação por antecipação, para cada bactéria. O uso das diversas associações possíveis deve ser feito com a preparação de soluções aquosas para administração via oral tanto para uso veterinário como para uso humano. [031] A Biguanida polimérica PHMB (Polihexametileno Biguanida) pode ser encontrada no mercado facilmente em solução a 20% para ser utilizada como matéria prima para formulações de desinfetantes, sendo disponibilizada em larga escala no Brasil, pela IPEL e ArchQuimica. Este composto quando usado em associação aos antibacterianos e/ou antibióticos no tratamento das infecções causadas por bactérias em animais, reduz drasticamente o MIC (Concentração Mínima Inibitória). A redução do MIC chega até 4 vezes ou mais .dependendo do antibacteriano usado e da bactéria desafiada. Nos testes "IΝ VITRO” os antibacterianos e a Biguanida polimérica individualmente não têm o mesmo resultado em comparação aos obtidos quando usados em associação. [030] The composition called , antibacterial association reducing the resistance of bacteria and method of obtaining, object of the present invention, deals with the concomitant use of polymeric biguanide PHMB at 20%, used in proportion in the basic dose of 20 ppm, in association with antibiotics and/or antibacterials, these in the dose recommended by the manufacturers. The antibiotics and/or antibacterials used can be any one indicated in human and veterinary medicine for the various bacterial infections and approved by Organs competent bodies such as ANVISA and MAPA. The dosage of antibiotics and/or antibacterials used in association with PHMB is determined by the objective application obtained according to the antibiogram of the causal agent of the disease to be fought, however, the ideal dose of the association can be established in advance for each bacteria . The use of the various possible combinations should be made with the preparation of aqueous solutions for oral administration for both veterinary and human use. [031] Polymeric Biguanide PHMB (Polyhexamethylene Biguanide) can be found in the market easily in 20% solution to be used as raw material for disinfectant formulations, being available in large scale in Brazil, by IPEL and ArchQuimica. This compound when used in association with antibacterials and/or antibiotics in the treatment of infections caused by bacteria in animals, dramatically reduces the MIC (Minimum Inhibitory Concentration). The MIC reduction is up to 4 times or more depending on the antibacterial used and the bacteria challenged. In the "IΝ VITRO" tests, the antibacterials and polymeric biguanide individually do not have the same result compared to those obtained when used in combination.
[032] A composição aqui descrita e seu método de obtenção é o resultado de muitas pesquisas para encontrar uma forma de revitalizar os medicamentos existentes que não fosse um novo antibiótico e sim uma substancia que conseguisse anular a proteção criada pelas bactérias para se proteger da ação dos próprios medicamentos em uso, fragilizando a sua resistência. . [032] The composition described here and its method of obtaining it is the result of much research to find a way to revitalize existing drugs that was not a new antibiotic but a substance that could nullify the protection created by the bacteria to protect itself from the action of the medications in use, weakening their resistance. .
[033] De fato uma substancia para ser utilizada como medicamento deve ter características especificas. Possuir Baixa ou nenhuma toxicidade na dose utilizada para os animais e humanos; ser solúvel em água para ser consumida juntamente com os medicamentos no tratamento por via oral e adsorvida pelo trato gastrointestinal (Ação sistémica); ser isenta de sabor e odor; ser muito ativa contra bactérias Gram-negativas e Gram-positivas, em baixa doses; possuir nenhuma toxicidade sistémica; eliminada por completo pela urina; deve ter viabilidade económica para ser compatível com custos de tratamentos tanto dos animais como dos seres humanos. Estas características foram encontradas nas Biguanida poiimérica, fato que ensejou os testes ΊΝ VITRO” que confirmaram a ação sinérgica com os antibacterianos versus as bactérias patogênicas. [033] In fact a substance to be used as a medicine must have specific characteristics. Have low or no toxicity in the dose used for animals and humans; be soluble in water to be consumed along with drugs in oral treatment and adsorbed by the gastrointestinal tract (Systemic action); be free of taste and odor; be very active against Gram-negative and Gram-positive bacteria at low doses; have no systemic toxicity; eliminated completely in the urine; it must be economically viable to be compatible with treatment costs for both animals and humans. These characteristics were found in Polymeric Biguanide, a fact that gave rise to the 'VITRO' tests, which confirmed the synergistic action with antibacterials versus pathogenic bacteria.
[034] A Figura 3 mostra a ação do composto PHMB atacando bactérias Gram- negativas, que tem uma camada extra de membrana, externa a parede celular. PHMB ataca a célula, ligando-se à membrana: sendo que o PHMB é uma molécula carregada positivamente, ao passo que a parede celular é carregada negativamente. Agindo como um imã o PHMB atrai fragmentos da célula. Em primeiro lugar a membrana externa, em seguida PHMB viaja através da camada de peptidoglicanos, como a água através de um filtro, para atrair a membrana interna. A parede celular começa a “ceder” e suas camadas de proteção são "lascadas”, fazendo com que o citoplasma vaze e a célula entre em colapso deixando para trás apenas um esqueleto. Esta rápida destruição eletrostática ocorre da mesma forma com bactérias Gram-positivas que não tem uma membrana exterior. O PHMB atrai, liga-se e aniquila. [034] Figure 3 shows the action of the PHMB compound attacking Gram-negative bacteria, which has an extra layer of membrane, outside the cell wall. PHMB attacks the cell, binding to the membrane: PHMB being a positively charged molecule, while the cell wall is negatively charged. Acting like a magnet, the PHMB attracts cell fragments. First the outer membrane, then PHMB travels through the peptidoglycan layer, like water through a filter, to attract the inner membrane. The cell wall begins to "sag" and its protective layers are "splintered", causing the cytoplasm to leak and the cell to collapse leaving behind only a skeleton. This rapid electrostatic destruction occurs in the same way with Gram-positive bacteria that doesn't have an outer membrane. PHMB attracts, binds and annihilates.
[035] A tecnologia que reduz a resistência bacteriana, objeto desta invenção, consiste nas associações possíveis do PHMB com medicamentos diversos cujo interesse e responsabilidade é das empresas fabricantes de produtos veterinários e/ou humanos que deverão formular os novos produtos conforme as leis vigentes e registrá-los no MAPA ou na ANVISA , Somente depois de devidamente registrados poderão ser comercializados e usados. [035] The technology that reduces bacterial resistance, object of this invention, consists of the possible associations of the PHMB with various drugs whose interest and responsibility is of the manufacturers of veterinary and/or human products that must formulate the new products in accordance with current laws and register them at MAPA or at ANVISA. Only after duly registered can they be sold and used.
[036] Assim, a composição anti bacteriana redutora da resistência das bactérias, trata-se de uma composição de uma solução de Biguanida poiimérica PHMB a 20%, ou utilizada em proporção de na dose de 20 ppm em mistura, em associação com antibióticos e/ou bactericidas na dose especifica mínima para a aplicação objetiva desejada MIC, sendo uma composição em solução para administração via oral para uso veterinário ou humano. Onde os antibióticos e/ou bactericidas poderem ser: a penicilina para doenças respiratórias, a ciprofloxacina para doenças urinarias, a sulfa+trimetropim para doenças entéricas, com as especificações conhecidas de cada aplicação e utilização indicadas a cada caso, e ainda poderem ser quaisquer antibióticos e/ou bactericidas já conhecido adequados a cada doença ou bateria a ser combatida. Onde a dosagem dos antibióticos e/ou bactericidas ser determinada pela aplicação objetiva obtida de acordo com o antibiograma da doença a ser combatida, ou através do antibacteriano da bactéria ou da doença a ser combatida. [036] Thus, the antibacterial composition that reduces the resistance of bacteria, it is a composition of a solution of polymeric biguanide PHMB at 20%, or used in a proportion of at a dose of 20 ppm in mixture, in association with antibiotics and /or bactericides in the minimum specific dose for the desired objective application MIC, being a solution composition for oral administration for veterinary or human use. Where antibiotics and/or bactericides could be: penicillin for diseases respiratory diseases, ciprofloxacin for urinary diseases, sulfa+trimethoprim for enteric diseases, with the known specifications of each application and use indicated in each case, and can also be any antibiotics and/or bactericides already known suitable for each disease or battery to be fought. Where the dosage of antibiotics and/or bactericides is determined by the objective application obtained according to the antibiogram of the disease to be fought, or through the antibacterial of the bacteria or disease to be fought.
[037] A composição antibacteriana redutora da resistência das bactérias, consiste na mistura por agitação até diluição de 50 a 250 rpm, à temperatura ambiente da solução a 20% de Biguanida polimérica PHMB (Polihexametileno Biguanida) em solução, com antibacterianos e/ou antibióticos na proporção determinada pelo MIC (Concentração Mínima Inibitória) para cada doença a ser combatida. [037] The antibacterial composition that reduces the resistance of bacteria, consists of mixing by stirring until dilution of 50 to 250 rpm, at room temperature, of the 20% solution of polymeric biguanide PHMB (Polyhexamethylene Biguanide) in solution, with antibacterials and/or antibiotics in the proportion determined by the MIC (Minimum Inhibitory Concentration) for each disease to be fought.
