Description:FIELD OF THE INVENTION
[0001] The present disclosure relates generally to the field of pharmaceutical and veterinary composition. Particularly, the present disclosure provides a formulation for wound healing management. The present disclosure also provides a method of preparation of a formulation for wound healing management. The formulation can be used for different wound healing of domesticated, farm and small animals.
BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] The management of wounds depends on the type of wound healing which can include irrigation, mechanical and chemical debridement, the use of antiseptics and antimicrobials, and adherent and nonadherent dressings. Quality of care is a critical requirement for wound healing and 'good' care of wounds has been synonymous with topical prevention and management of microbial contamination. Topical antiseptics are antimicrobial agents that kill, inhibit, or reduce the number of microorganisms and are thought to be essential for wound infection control. However, they have long and commonly been used on wounds to prevent or treat infection, and the merits of antiseptic fluid irrigation have received little scientific study. Unlike antibiotics that act selectively on a specific target, antiseptics have multiple targets and a broader spectrum of activity, which include bacteria, fungi, viruses, protozoa, and even prions. Although certain skin and wound cleansers are designed as topical solutions with varying degrees of antimicrobial activity, concerns have been raised.
[0004] Dressings are a part of a holistic wound management plan with individualized patient goals and aimed to provide the optimal environment for healing processes. Different dressings have been used in veterinary clinical practice to promote healing during different phases of wound healing. Bandage after dressing may cause discomfort for animals.
[0005] Huebner et al. [J. Dairy Sci., 2017, 100, 3922–3929] discloses a topical aluminum bandage spray improves wound healing during the 3 wk following disbudding. The results of this study stated that the use of ALU improved wound healing following cautery disbudding of pre-weaned dairy calves.
[0006] Umar et al. [Drug Des Devel Ther., 2020, 14, 2909-2925] discloses the types and concentrations of polymers and excipients, sprayer types, evaluations, and critical parameters in determining spray ability and film characteristics. The review concludes that both natural and synthetic polymers that have in situ film or viscoelastic properties can be used to optimize topical drug delivery.
[0007] Bakhrushina et al. [Saudi Pharm J., 2023, 31, 154-169] relates to a Spray Film-Forming systems (SFFSs) as promising topical in situ Systems. This review highlights most of the existing requirements and suggestions from studies to standardize the characteristics of SFFSs and classify them based on scientific sources and regulatory documentation, as well as the position of such systems in the pharmaceutical market.
[0008] Most of the marketed preparations are either herbal sprays OR ointments with fly-repellant properties. These preparations are used after wound dressing. However, there is no definite protection for wounds from dust, dirt, microorganisms, and water. The literature on herbal ointment spray against microorganisms is scanty/limited. The currently marketed preparation does not provide sufficient protection to the wound surface. Bandaging is also not a common practice in farms and small animals, due to the licking, and scratching habit. There is a definite need to protect the wound from environmental contaminants. Thereby promoting wound healing. Therefore, there is a need to develop a newer approach for wound healing management.
OBJECTS OF THE INVENTION
[0009] Primary object of the present disclosure is to provide a formulation that overcomes one or more limitations associated with the conventional compositions/formulations.
[00010] An object of the present disclosure is to provide a formulation for wound healing management.
[00011] Another object of the present disclosure is to provide a method of preparation of a formulation for wound healing management.
[00012] Another object of the present disclosure relates to a formulation that provides a protective layer on the wound surface.
[00013] Still another object of the present disclosure is to provide a formulation that avoids the usage of bandage.
[00014] Further object of the present disclosure is to provide an aerosol spray for wound healing management.
[00015] Still further object of the present disclosure is to provide an aerosol spray that protects the wound from bacteria, dirt, and environmental irritants.
[00016] Yet another object of the present disclosure is to study the sealing and healing effects of the topical aerosol spray in management of wound.
[00017] Other objects of the present invention will be apparent from the description of the invention herein below.

In a more preferred embodiment, the formulation for wound healing management comprising: 2.5 to 3 % w/w of a first antibiotic of the total weight of the formulation; 0.1 to 0.5 % w/w of a second antibiotic of the total weight of the formulation; 2 to 2.5 % w/w of a third antibiotic of the total weight of the formulation; 5 to 7 % w/w of an aluminium powder of the total weight of the formulation; and rest being one or more solvent.
[00070] Still another aspect of the present disclosure provides a method of preparation of a formulation for wound healing management comprising: a) dissolving 1.5 to 3.5 % w/w of a first antibiotic in a solvent with agitation to obtain a first solution; b) dissolving 0.1 to 1 % w/w of a second antibiotic and 1.4 to 3.5 % w/w of a third antibiotic in a solvent with agitation to obtain a second solution; c) mixing of the first solution and the second solution to obtain a third solution; d) adding 2 to 10 % w/w of an aluminium powder in a solvent with stirring to obtain a mixture; and e) adding the third solution of step c) in the mixture of step d) with stirring to obtain a formulation for wound healing management.
[00071] In an embodiment, the first antibiotic, the second antibiotic and the third antibiotic are neomycin, polymyxin and bacitracin zinc respectively.
[00072] In an embodiment, the wound healing formulation in step e) has a pH in the range of 3.5 to 4.5.
[00073] In an embodiment, the method is carried out at a temperature in the range of 20 to 30 °C, preferably at a temperature in the range of 23 to 27 °C with RH in the range of 45 to 65 %, preferably RH in the range of 50 to 60 %.
[00074] Polymyxin B is one of a group of closely related substances produced by various strains of Bacillus polymyxa. The activity of polymyxin B is sharply restricted to gram-negative bacteria.
[00075] Neomycin, isolated from Streptomyces fradiae, has antibacterial activity in vitro against a wide range of gram-negative and gram-positive organisms.
[00076] Bacitracin, an antibiotic substance derived from cultures of Bacillus subtilis (Tracy), exerts antibacterial action in vitro against a variety of gram-positive and a few gram-negative organisms.
[00077] In an embodiment, the present formulation contains neomycin, bacitracin, and polymyxin, antibiotics that work by stopping the growth of bacteria.
[00078] Aluminium-based aerosol bandage sprays are commonly used as a protective bandage over wounds, and the product claims that the product works as a waterproof barrier protectant and does not damage wound tissues. It claims that the product works as a waterproof barrier protectant, does not damage wound tissues, adheres to the skin, allows the skin to oxygenate, and acts as a dry barrier against mud, debris, and sensitivity to sunlight. The exact mechanism of action for ALU is currently unknown, and the product may be acting at one of several stages in the healing of thermal wounds. In superficial burn wounds, the stages of wound healing include haemostasis, inflammation, proliferation, and maturation and remodelling of the tissues, including wound contraction, granulation, and re-epithelialization. The difference between burn wounds and other traumatic wounds is that they are characterized by fundamental damage to vital tissues, which complicates the normal wound healing response, as cells and vasculature are often destroyed, leading to a region of coagulative necrosis. The aluminium may be acting as a drying or astringent agent to accelerate wound contracture or reduce inflammation/infection associated with coagulative necrosis. It is not known how ALU would affect healing of other types of wounds. Aluspray forms a waterproof aluminium powder barrier for wounds and sensitive skin. The fine mist completely covers the wound and can be applied without damaging the wound tissue. It contains a proprietary carrier that helps the protective formula to adhere to the skins and allows the wound to breathe which is essential for good healing. Aluspray forms a protective barrier against moisture, micro-organisms, dirt, flies, ideal post castration and post dehorning.
[00079] In the present invention, it is often observed that the wound is contaminated with different microorganisms, such as gram-positive and gram-negative bacteria, aerobic and anaerobic bacteria and sometimes viruses may delay the wound healing process. Therefore, it is essential to control infection at the site of a wound. Hence the present antibiotic combination will clean the infection and aluminum powder form a protective layer coating (Over the wound surface). Thus, the mechanism of the present invention involve that the combination of antibiotics and the aluminum powder is a newer approach that provides a protective thin layer on the wound surface to avoid entry of dust and dirt and prevent entry of bacteria.
[00080] The present invention provides protection against physical, chemical and biological barriers stopping the infection and keeping the dirt and bacteria out while allowing the wound to heal faster. It gives the spray-seal-heal with antibacterial activity.
(A) Biological barrier: Neomycin, Polymixin B and bacitracin zinc offers broad spectrum bactericidal effect indicating its antibacterial property.
(B) Physical barrier: Makes a protective layer on line or site of wounds act as catalyst in collagen formation, reduces cellular permeability and avoids extra granulation indicating its coating property.
(C) Chemical barrier: Sealing of wounds- does not allow fly to sit on wounds indicating its fly repellant property.
[00081] Still another aspect of the present disclosure relates to a method for wound healing management, said method comprising administering to a subject in need thereof a formulation comprising: 3 to 8 % w/w of one or more antibiotics of the total weight of the formulation; 2 to 10 % w/w of an aluminium powder of the total weight of the formulation; and rest being one or more excipient.

(E) FIELD TRIAL OF FORMULATION (AEROSOL SPRAY) IN THE MANAGEMENT OF DIFFERENT WOUNDS IN DOMESTICATED ANIMALS, FARM AND SMALL ANIMALS
[00092] The objective of this study is to evaluate the sealing and healing effects of the Topical aerosol spray of the present invention in management of wound.
[00093] Aerosol spray (Wound healing spray) of the present invention was used for treatment of open, surgical and maggoted wounds in small and large animal practice. A total of 20 routine cases of wounds (open, maggoted and surgical) from day to day OPD were selected for the study. Most of the cases from panjarapole animals were treated as inpatients were as some small and large animals were treated as outpatients as per depending upon the convenience of the owner. Spraying was conducted with start to end and end to start, also top to bottom and bottom to top method. This provided complete wound sealing and coverage on the surface of the wound. The dressings were conducted on every alternate days as, 1, 3, 5, 7, 9 and so on depending upon the size and nature of the wound. The efficacy of the study were done by evaluation of parameters VIZ; Days required for completion of healing, capacity to protect from flies, degree of controlling exudation and maggoticidal action.
[00094] As per recommended usage suggested, aerosol spray of present invention was used after shaking 10-20 times keeping a straight direction so as the solution gets uniformly mixed before application. Aerosol spray of the present invention forms protective barrier (Film formation) on wound surface that protect wound form entry of dust and dirt. It also allows wound to oxygenate (Breath) which is important for wound healing.
(i) Management of surgical aseptic wound after rumenotomy:
[00095] The sealing spray was applied on the post-surgical suture line in case of rumenotomy in individually operated animals on every alternate days (1, 3, 5, 7, 9, 11…) till normal recovery. Post operatively, complete healing was observed within 9 to 12 days in large animal. From FIG. 3, it can be seen that the healthy tissue formation on 7th day onward in large animal.
(ii) Management of surgical wound in panhysterectomy in female dog
[00096] A mastiff female dog undergone panhysterectomy after being diagnosed for pyometra. The surgical wound healing observations as shown in FIG. 4. Effective healing of suture line was observed from day 5th and showed complete recovery on 7th day. Post operatively, complete healing was observed within 7 to 9 days in small animal. From FIG. 4, it can be seen that the healthy tissue formation from 5th day in small animal. It seems that the spray is effective surgical wound healer. While treatment procedure, no evidence of fly’s around the uncovered surgical suture line were seen after use of sealing spray. Hence reducing the chances of maggot infestation.
(iii) Management of dog bite wound in goat
[00097] A goat with suppurative wound following dog bite was successfully treated with healing spray. As fistulous wound, spray content was guided with ear buds to reach deep into the open tract of the wound. The septic wounds treated with the spray showed effective healing from day 3rd with no evidence of exudation at the wound site (FIG. 5). The wound surface remained dry. Effective healing was observed in most of the animals within 8 to 15 days depending upon the depth, site and area of wound. Overall, it seems that the healing spray used for septic wound had effective penetration promoting faster healing and protective coverage at the infected site.
(iv) Open sepsis wound in cat
[00098] A cat presented with chronic suppurative wound on the right lateral abdominal region. Excessive suppurative discharge from the infective wound was observed. Affected area was cleaned and dressed with wound healing spray. Effectively, the suppuration was reduced considerably from 5th day onward and showed granulation with reduced sepsis (FIG. 6). Almost effective healing was evident till 13th days.
(v) Open sepsis wound in foot rot in cattle
[00099] A cow presented with foot rot lesions at right fore limb and foot rot with maggot infestation at left fore limb. Complete healing of left fore limb with maggots was attained on 11th day and that with only foot rot lesions in right fore limb healed up at 9th day as shown in FIG. 7.
(vi) Management of maggoted wound in dog
[000100] A case of Labrador male dog with history of chronic non healing scrotal wound with maggot infestation was presented and considerable loss of tissue at the affected site were evident. Initially, treated with wound healing spray at site of deep seated holes on the scrotal tissues. Maggots started excavating the wound within 3 minutes but complete death of the maggots was not attained as few to some maggots remained alive at the site. Although tissue damage for scrotum was much more and pet was also not cooperative causing additional damage to scrotal tissues by self licking. Hence, dog was operated for scrotal amputation which later recovered effectively. As per routine practice, the cases with maggot infestation were treated with spray at the infected site.
[000101] After spraying, excavation of maggots took place within 3 to 5 minutes but complete death of the maggots was not so potent.
• Few to Some Maggots remained alive and present within or on the wound for some period.
• However the healing effect was found promoting.
• Re infestation of the maggots was not observed at the treatment site.
[000102] Considering the uniform and complete wound coverage property with effective fly repelling property makes the spray better option to counter act the maggoted wounds in large and small animal practice (FIG. 8).
(vii) Retention of spray on the surface of the skin
[000103] After uniformly spaying the wound site it was observed that the spray line remained intact for 36 to 48 hours. Hence alternate day dressings can be manageable while using the sealing spray. None of the animal treated with spray showed any allergens, urticaria, irritation, redness, oedema and cellulitis.
[000104] Spray line at the surface of the surgical closure remained intact from day first to day 5th. This cow was not dressed for 5 days. Intact wound healer spray line can be easily appreciated till day 5 as shown in FIG. 9. This indicates the evidence of sealing at wound site.
(viii) Farm and small animals
[000105] The formulation of the present invention was also applied on the farm and small animals having post-surgical dressing, maggot infested wound, septic wound and the formulation was found very effective.
[000106] The foregoing examples are merely illustrative and are not to be taken as limitations upon the scope of the invention. Various changes and modifications to the disclosed embodiments will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the invention.
