Definitions
- the present invention relates to a new composition for the local treatment of burns, abrasions, erythema, eczema, herpetic infections, avulsions, superficial ulcers and any skin lesion that causes damage, and in particular, a composition which creates a transparent colloidal film.
- a composition which creates a transparent colloidal film on the lesion covering the nerve terminals (pain relief), decreasing nervous irritability, isolating from the external environment to prevent contact with harmful substances, maintaining the dryness of the lesion and pressing (effect effect) to create a means that allows effective and rapid cell regeneration; Meanwhile the enzymatic action deflates, debrides and cleanses the area.
- Reconstructive and burned surgery applied science that is part of the specialty of plastic surgery, is the area where the specialist is dedicated to rebuild tissues, treat burns and repair the skin cover when it is lost.
- Antibiotic substances such as silver sulfadiazine, furacin (fucidin), terramycin and others of different types have tried to occupy this space in medical therapeutics.
- the philosophy is to give comfort to the patient while the body itself exercises healing processes.
- a burn is defined as the skin lesion caused by a transfer of energy from a thermal source to the body intense enough to cause damage, which can occur by direct (caloric) conduction, chemical injury or electromagnetic (electrical) radiation.
- Burn occurs when the skin cells have been destroyed by heat, release chemicals that stimulate the nerves causing pain, cause loss of continuity of the skin with exposure of the underlying elements and, depending on the degree of depth, fluid loss by evaporation
- the healing mechanism of a burn is similar to that of a wound or abrasion; in the second degree, serum blisters are formed that act as a protective covering and under it a new layer of skin is formed from the edges of the burn.
- the burn is one of the most frequent injuries that occur to humans. In the US between 3.5 to 4 million people visit the doctor a year for diagnosis and treatment of burns.
- the main protein is albumin that gives the oncotic pressure (fluid retention) of the plasma and passes into the extravascular space in the burn retaining fluids in what is called edema.
- leukocytes macrophages and neutrophils (white immune cells of the circulation) responsible for cleaning and disinfecting the area, defense system against bacteria and removal of dead cells.
- euglobin capillary permeability
- catecholamines leucotaxin bradykinin
- calidine calicrein
- histamine histamine
- serotonin prostaglandins
- prostaglandins all substances that they cause nerve stimulation, cellular immune activity, vasodilation, cell migration (chemotaxis) and other changes related to inflammation.
- First Grade Surfaces In which only the outermost layers of the epidermis or cornea layer are affected. It is characterized by an erythema or red color, intense pain, local heat, sensitivity to air, contact and spontaneous healing in three or four days. They can cause hyperpigmentation of the skin. An example is sunburn: heals in a few days without scarring.
- Deep complete destruction of the epidermis (including the germination layer) and part of the dermis, flictenas, pale pink tone, moderate pain (due to nerve destruction), hard and stiff skin, slow capillary filling and delayed healing originating in the annexes (hairs and glands), and almost always leaves a scar.
- An example is the vapors or flamazos, in which case they regenerate in 16 days.
- the first and second superficial degree burns are those that have spontaneous healing and are the main object of the applicability of the composition of the present invention.
- Determining the origin of the burn is very important to define the intensity of the injury, its treatment and prognosis.
- a superficial burn is considered to be one that can be treated outpatiently at home or without complications and does not exceed 25% sct and second superficial degree in adults, and 10% and second superficial degree in children.
- the treatment focuses on preventing overinfection, loss of fluids, deflating the area, providing comfort, giving analgesia, cleaning the area, covering the burned area and protecting it from the environment while the intrinsic healing processes act.
- the treatment is to cover the area, clean it, inspect it, wash it, remove the pain and debride it; preventing superinfection and allowing for a reepithelialization and total healing in a maximum period of 3 to 5 days; the use of analgesics, antibiotic substances and other products for local cover is avoided.
- this local burn treatment it is that the new composition object of the present invention has been designed.
- the objectives of local burn treatment are to protect against infection and trauma, reduce pain, reduce inflammation, and accelerate the removal of devitalized tissue while promoting methods that accelerate healing.
- SSD silver sulfadiazine
- Endogenous proteases are produced by several cells in a burn. These enzymes promote liquefaction and removal of necrotic tissue; devitalized protein residues must be removed to allow epithelial cells to be able to migrate and repair the surface of the burn.
- Collagenases are intrinsically produced proteases (enzymes) that act exclusively on the collagen by denaturing it and making it more easily degradable by less specific proteases.
- Exogenous protease preparations have been made for several decades to accelerate the debridement process of burns and lesions by increasing the rate of local protein degradation and thereby expediting the epithelialization process. This results in a decrease in the intensity of the injury, less hours of care for the injury, and less discomfort for the patient.
- Exogenous collagenase is achieved in an enzyme preparation derived from the clostridium histolyticum bacteria.
- Hyperemia is a physiological response to trauma, it is followed by inflammation, a prerequisite for healing, and subsequent ed.ema, which generally slows healing. If the edema is excessive, it can delay tissue metabolism by increasing the possibility of infection, ischemia and hypertrophic scars. It is convenient to use methods that reduce edema.
- Edema represents an excess of fluids and cellular debris in the tissue spaces and its elimination depends on the liquid drainage (it can be by pressure) and proteolysis, that is, an increase in the elimination of protein residues by proteolytic enzymes. It is proven that (medical platform 354 1968) enzymes from papaya carica reduce to a minimum the edema associated with inflammation in the injuries in the process of healing, which correlates directly with a significant decrease or absence of pain.
- herbs, aloe vera, mucilages, etc., to tannins, mercury and topical antibiotics are the range of substances used to treat skin lesions from burns (or abrasions) demonstrating the lack of unanimity of criteria in this regard.
- Empirical treatment such as coffee, onion, egg white and different substances that come from the popular procedure are used in addition to an established medical management based on antibiotics and substances that scab like chromium mercury that have to be associated with analgesics and lubricants for lesions described.
- cerium nitrate which causes pain
- tannins which causes pain
- rifampin triconjugated treatment
- This treatment has antiseptic weakness and produces a bedsore that can predispose to bacterial culture.
- -Mafenide (sulfamilon) is a methylated sulfonamide (sulfa group) effective against a large bacterial group, especially clostridia, penetrates the eschar and can cause metabolic acidosis.
- -Silver nitrate An inorganic salt with poor penetration of the lesion, helps to remove the bedsore, under a bacterial spectrum.
- -Sulfadiazine silver formed by sulfadiazine and silver nitrate, penetrates the bedsore, and is effective against the entire bacterial spectrum of burns.
- proteolytic enzymes the application of proteolytic enzymes in a burn with local sepsis is very useful because it interrupts coagulation, eliminates accumulated proteinaceous material that "covers" the bacteria from antibiotic action and therefore increases the effectiveness Antibiotic preventing infection.
- An objective of the present invention is to provide a topical composition for the treatment of burns and skin lesions that cause sphalous, from each of the factors that causes a superficial burn or abrasion: pain, for which the thickener was designed as second skin (which causes analgesia), inflammation, for which the proteolytic enzyme was designed with potent enzymatic debriding effect, which are the basic concepts of the gel.
- compositions that in addition to containing the aforementioned components, may also contain other components for secondary (non-primary) factors of burns, such as adding antiseptic (chlorhexidine) in case of infectious suspicion, urea for greater lubrication and anesthetic (lidocaine) for painful lesions in adults and especially in children.
- antiseptic chlorhexidine
- urea for greater lubrication
- anesthetic lidocaine
- the sepsis of the burned wound or burn is defined by Teplitz as: presence of bacterial organisms exceeding 100,000 colonies per gram of tissue in the burned tissue and that are actively invading the tissue underlying the burn (artz cap 17 pg 250).
- Topical antibiotic therapy does not sterilize the burn, it simply reduces the number of bacteria seeking to allow the host's immune mechanisms to control the infection.
- HYDROGELS a novel complementary approach different from the local burn therapy
- HYDROGELS aimed at providing comfort, analgesia and pain relief in a short time in the burned or avulsed area, in addition to an anti-inflammatory and debriding effect.
- Such an approach is not an antibiotic therapy, nor is it indicated to remove bedsores, it is about forming a soft, transparent and colloidal layer isolating the area and consequently, preventing bacterial over-infection.
- the new composition of the present invention was designed from each of the factors that causes a burn or superficial abrasion: pain, for which the thickener was designed as a second skin (which causes analgesia), inflammation , for which the proteolytic enzyme was designed with potent enzymatic debriding effect, basic concepts of the gel.
- the indications of the present invention are for the treatment of first degree lesions, superficial second degree lesions, not infected, that are not in special areas and that have less than 25% extension.
- the composition of the present invention has a new clinical approach with the following characteristics: it is a transparent, anti-inflammatory film, reduces pain, isolates the injured area, has rheological power, prevents infection, is water absorbent and produces rapid epithelialization and efficient.
- the mixture, affinities and properties of the described substances focused on the pathology for which they were prepared, result in a specific formula for the treatment of the signs and symptoms present in the burns or Avulsions
- This new composition offers comfort in its use and application, immediate or mediate analgesia and a proteolytic debriding effect. It forms a transparent layer that allows a direct view of the lesion and a colloidal effect of pressure that exerts pressure by immediately isolating it from the external environment.
- the composition also offers other advantages such as its easy application and removal, being free of adverse effects for the patient, not being toxic to the tissues, painless to its indicated application, immediate analgesic effect, not staining or discoloring the wound and having low cost.
- the composition creates a transparent colloidal film on the lesion covering the nerve terminals (pain relief), isolating from the external environment to prevent contact with harmful substances, maintaining the dryness of the lesion and pressing (effect effect) to create a medium that allows efficient and rapid cell regeneration; Meanwhile the enzymatic action deflates, debrides and cleanses the area.
- composition of the present invention is to treat with each of its components the points of the pathophysiology of the burns: the pain occurs by the exposure in which the nerve endings remain and the gel creates a transparent outer layer that covers the skin while the natural and normal epithelialization process occurs. This layer makes this process to be carried out faster because the conditions and the environment are more suitable (cleaning, debridement, protection).
- Inflammation occurs due to physiological processes of reaction to damage (vasodilation, cell migration, release of active substances such as histamine and serotonin) and the efficiency of papain and enzymes in topical treatment and management of dermal inflammatory processes is proven.
- Papain It is a plant proteolytic enzyme of papaya carica that hydrolyzes peptide, amide and steric protein bonds.
- thermostability Its properties are to have a good proteolytic activity, good thermostability, it is heat-soluble, anti-inflammatory and has a debriding effect. In particular, it has a proteolytic activity between pH 3 and pH 9, a wide range of thermostability (up to 70 ° C), is poor in germs and dissolves easily in water, and is highly effective in viscous solutions.
- Papain has many uses: digestive substance that supports or replaces digestive enzymes, anthelmintic use to destroy the protein cuticle of intestinal worms, leather industry, tobacco, textiles and meat softeners. In wounds and burns it presents proteolytic activity on dead tissues, without attacking living tissues, causing enzymatic clearance and optimal healing. It has an inherent anti-inflammatory effect and is combinable with certain antibiotics. It is also used in biochemistry to break bonds and determine chemical structures of other proteins (such as the determination of human IgG.)
- Papain is a protease that catalyzes the hydrolysis of esters and peptides and the most important amino acids that compose it are: tryptophan, tyrosine, phenyl-alanine, histidine and arginine.
- Papain is preferably used in the composition in a range between 0.2 and 5% by weight of the composition, preferably in an amount of 0.5% by weight of the composition.
- composition of the present invention is a synthetic resin of acrylic acid, thickener, emulsifier and coalescing of interfaces (consistency). Its properties in the composition of the present invention are the following:

- carbopoles There are many types of carbopoles, the most important being carbopol 941, carbopol 940, carbopol 934, carbopol ultrez 10, carbopol etd-2020.
- Carbomer polymers have been used for rheological control (structure building agents) for lotions, creams and gels. Polymer molecules have a unique ability to increase the viscosity of liquids in which they have dissolved (dispersed) even in very humid concentrations. This is due to the bulky expandability (water absorption) of carbomer microgels.
- the ability of a polymer to increase viscosity depends on its "intrinsic viscosity.”
- the units in which "intrinsic viscosity" is expressed are dL / g.
- the factors that affect the intrinsic viscosity of a carbomeric polymer are: pH, types of electrolytes and ion concentration.
- Microgel particles in polymers increase the viscosity of a solution through two mechanisms: 1) increase in viscosity in direct proportion to the magnitude of swelling of the polymer, and 2) increase in viscosity by stiffness of the microgel.
