[0093] The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
[0094] Technical Problem: There are three primary issues with topical dosage forms 1) Efficacy and 2) Patient compliance and 3) Clinical needs.
[0095] Efficacy: No fast acting Topical creams & Ointments.
[0096] Pharmaceutical dosage from in oral dosage forms there are immediate release and orally disintegrating product. However, topical products do not have an immediate release product for a rapid onset. This is primarily the topical product ointments and creams that are made with active drugs along with excipients that that have a thick consistency to hold the drug for a longer time when applied on to the skin. Also, the excipients intend to melt at body temperature when applied into a thin layer on to the skin. When the ingredients are exposed to cold conditions like in Minnesota, New York, and other Northern states that experience cold weather conditions, the excipients may become hard in the cold conditions and may have inconsistent release of drug and it may prolong the onset effect.
[0097] Transdermal Patches: The drug is stored in the Transdermal drug delivery system (TDDS) either in a reservoir or impregnated into the fabric or to the adhesive of the patch.
[0098] Pharmacokinetics of topical products (ointment and creams): The drug absorbed into the skin follows a three-step process from ointment creams and TDDS. Step #1: Drug concentration gradient is developed with in the formulation and the drug starts to move down the gradient. The ointment or cream of topical product needs to absorb water from the skin and dissolve the drug in the formulation and form a concentration gradient within the formulation. Step #2: A second drug reservoir is established in the stratum corneum. As the drug moves further into the skin, Step #3: The drug is absorbed into the local capillary vasculature and is then transported into the systemic circulation.
[0099] As a result of this absorption process, there is a delay between Topical drug products/TDDS application and the development of a desired minimum effective concentration (MEC). This delay varies between drugs. There is an initial period in which drug concentrations are hardly measurable. The time to reach steady-state plasma concentrations vary considerably and may be achieved completely only after two to three patch applications (1).
[0100] The disadvantage of the topical drug delivery is on the lack of rapid onset of action as the drug takes some time to get released from its vehicle and then to penetrate (absorb) through the skin and there are variations between individuals in the rate at which drugs are absorbed via the skin due to factors such as thickness of the stratum corneum, skin hydration, underlying skin diseases or injuries, ethnic differences, and body temperature.
[0101] Patient Compliance: Patients feel uncomfortable on application of topical medications, as it is often considered and reported by the patients as being more difficult than simply taking a pill (2, 3, 4). Patient, treatment, and disease factors have been appointed to justify poor adherence. Regarding treatment, poor acceptability of the topical vehicles properties as very greasy, desiccating, or sticky vehicles and the smell of the preparation and staining of clothes, time required for its application have been reported by patients with chronic skin disorders as barriers to optimal treatment adherence. Staining or messing of clothes is often associated with the use of ointments, creams, pastes, and gels. Also, the topical route is that it has no dosing accuracy, and it is difficult to formulate with different drugs and ingredients.
[0102] In the study on chronic skin diseases, stickiness (44%), and attachment to clothes (34%) and bed-clothing (27%) were reported to be the reasons of poor adherence, furthermore, being busy (25%). These results suggest that the reason for poor adherence to use topical ointment is complex. (6).
[0103] Clinical needs: Multimodal therapy approaches that combine interventions aimed at different aspects of disease are emerging as potentialand perhaps essentialways to enhance clinical outcomes for patients and this multimodal therapy approach in topical drugs is impossible except few combinations therapy in which two drugs are combined in one ointment or cream as a standalone topical product. If multiple drugs need to be applied for treatment at the same time, it is impossible to apply two or more products at the same time one up on another in the form of ointment or a cream but can be applied in different area of the skin. It is impossible to provide multimodal drug therapy for effective treatment in topical dosage forms.
[0104] Disease conditions: Shingles is a viral infection that causes a painful, burning rash that may appear as a stripe on the trunk of the body. There is oral treatment available, but due to constant pain and burning sensation, THADS technology will be helpful to keep the pain killer medication along with Antiviral and blister healing drug at all the time in contact with the rash associated with the Shingles to minimize the pain and expedite the healing process.
[0105] Multimodal drug administration: Romita Paolo Et al. (7). indicated in their study, that all the transdermal patches cause skin irritation and Allergic contact dermatitis, with THADS technology, Chlorpheniramine solution and Hydrocortisone 1% can be used along with the drug intended for treatment will eliminate the skin irritation and allergic contact dermatitis associated with topical delivery of drugs using transdermal patches.
[0106] With multimodal drug approach many acute disease conditions like pain, cancer and diabetes can be treated. Using THADS Appod, more than one drug or combination of two or three or more drugs can be administered at the same time, THADS system allows multiple drugs to be held in the treatment area for its absorption at the same time and helps the multimodal drug treatment of acute disease conditions.
[0107] Liver Toxicity from oral drugs. Topical delivery of large molecules like proteins and peptides of biotechnology products: most of the peptides and proteins of biotechnology products are delivered through subcutaneously or other parental route, due to high molecular weight of the compounds. THADS has the provision to deliver constantly the skin permeation agent along with proteins and peptides to deliver it through the skin. High drug content in Transdermal patches: FDA approved transdermal patches had very high drug content than it is really required, as shown below:
[0108] EMSAM transdermal systems are available in three strengths that deliver approximately 6 mg, 9 mg, or 12 mg of selegiline over 24 hours. Each corresponding system has an active surface area of 20 cm.sup.2, 30 cm.sup.2, or 40 cm.sup.2 containing 20, 30, or 40 mg of selegiline.
[0109] Lidoderm adhesive patch contains 700 mg of lidocaine, per 10 cm14 cm, but only 3% is bioavailable, i.e., only 21 mg of drug enter into to blood stream. Apply the prescribed number of patches (maximum of 3), only once for up to 12 hours within a 24 hour period.
[0110] Excelon 5 cm.sup.2 patch contains 9 mg rivastigmine base, with in vivo release rate of 4.6 mg/24 hours. Each 10 cm.sup.2 patch contains 18 mg rivastigmine base, with in vivo release rate of 9.5 mg/24 hours
[0111] Oxytrol 39 cm.sup.2 patch contains 36 mg of oxybutynin for nominal delivery of 3.9 mg oxybutynin per day when dosed in a twice weekly regimen.
[0112] Salonpas Pain relieving Lidocaine patch of 10 cm14 cm contains 560 mg of Lidoaine, Aspercreme patch 1014 cms contain 246 mg of lidocaine, Icyhot patch of 10 cm14 cm contains 240 mg of lidocaine and 60 mg of menthol. also, per package inserts a 100 mcg/h fentanyl TDDS containing 10 mg of fentanyl while a 0.3 mg/day clonidine TDDS has 7.5 mg of clonidine.
[0113] The marketed transdermal patches comprising the drug candidates mixed with adhesive, the drug has low diffusivity through the adhesive, so the drug content of the transdermal patches is very high than the quantity of drug is bioavailable.
[0114] The risk of toxicity and adverse outcomes are further increased if the TDDS is tampered with or used improperly.
Solution to Problems
[0115] The present invention has been made in view of the problems associated with the topical products/TDDS for human and animal products of ointment, creams, sprays, emulsion, suspension etc., an object of the present invention is to provide a rapid onset of action and patient compliance of hands free application using Topical product Hand free Applicator Drug delivery System (THADS) and a multimodal method for treating using the THADS.
[0116] The present inventors have conducted relevant study to achieve the above object. As a result, the inventors have found the following Topical product Hand free Applicator Drug delivery System (THADS). Specifically, Topical product Hand free Applicator Drug delivery System (THADS) System comprise a) A metered dose container that is airless container that can deliver a measured amount of drug at any (360 C.) angles of the container and formulation that is made as ready to act state which the drug is present in highly dissolved state less viscous compared to ointment and contains polypropylene that prevents freezing from cold conditions, alcohol for rapid drying after application and dimethyl sulfoxide to solubilize the hydrophilic and hydrophobic drug components and enhance skin penetration, b) A wand is a flexible and has two ends. end #1 can be attached and detached to the airless bottle and end #2 can be attached and detached to the sponge tip applicator. after connecting the wand end #1 to the airless container, drug is pumped from airless container, after pumping the drug the wand will be disconnected at end #1 and applied into the skin through the smooth sponge tip without using the hand, the solution is non-greasy and spreads easily, and it will dry rapidly. c) Appod, an adhesive bandage pod that can be applied to a part of the skin that needs to be treated for local and systemic application, the Appod will have an opening through which the end #2 of the wand will be inserted and the ready to act drug product solution will be pumped in for the necessary dose i.e. either one dose or multiple dose of the drug, from there the Appod will hold the drug very close in contact with the skin and for longer time and deliver the drug continuously in predetermined manner to the skin, The Appod act as reservoir that can deliver multiple drug continuously for treatment and the Appod will cover the drug product, cloths will not be soiled and will provide very efficacious treatment and high patient compliance for topical treatment.
[0117] Appod has adhesive on the border of the outer polymeric film, most of the on inner non-woven fabric or pad does not contain adhesive, the adhesive does not interfere the drug release through the skin, so the drug content requirement by using Appod will be low compared to the marketed transdermal patches.
[0118] Advantageous Effects of Invention: The present invention makes it possible to provide a THADS a multimodal method for delivering the drug product topically with enhanced ready to act drug form for immediate action, with exact dose needed producing the same efficacy each and every time and also with the use of Appod, which will cover the drug product from the cloths, unpleasant odor from drug, poor cosmetic properties, messy, sticky, or greasy vehicles and also enhance the consumer compliance from once-a-day dose administration.
[0119] Topical products are classified, and its description given in Table 1 below:
TABLE-US-00001 TABLE 1 Classification of topial formulation Classification of topical formulations Solution Water or alcoholic lotion containing a dissolved powder. It is used as tincture or wash and it will run through the skin if applied. Lotion Usually considered thicker than a solution and more likely to contain oil as well as water or alcohol. A shake lotion separates into parts with time so needs to be shaken into suspension before use. It can be applied on to the skin by taking in hand and applying it, it will stick on to the hand and cloths Cream Thicker than a lotion, maintaining its shape, for example, a 50/50 emulsion of oil and water.

[0121] Efficacy of topical products using THADS: Pharmacokinetics of currently marketed topical products (ointment, creams, and transdermal patches): The drug absorbed into the skin follows a three-step process from ointment creams and TDDS. Step #1: Drug concentration gradient is developed with in the formulation and the drug starts to move down the gradient. The ointment or cream of topical product needs to absorb water from the skin and dissolve the drug in the formulation and form a concentration gradient within the formulation. Step #2: A second drug reservoir is established in the stratum corneum. As the drug moves further into the skin, Step #3: The drug is absorbed into the local capillary vasculature and is then transported into the systemic circulation.
[0122] Pharmacokinetics of topical products using THADS: The drug absorbed into the skin follows a two-step process. Step #1 A reservoir is established at the stratum corneum directly, as the ready to act drug is held closer to the skin by Appod. As the drug moves further into the skin. Step #2 The drug is absorbed into the local capillary vasculature and is then transported into the systemic circulation.
[0123] THADS eliminates the one-time consuming step (step #1) of the pharmacokinetics of the topical products like ointment, creams and transdermal patches and put the step #2 directly and enhance the efficacy of the drug with the hands-free application, fast acting and with Appod it enhances the patient compliance.

[0126] Most of the FDA approved topical products are packed in a tube, and it is impossible to take the exact dose each time for use and here is the instruction provided for the application of topical drug from its tube.
[0127] With all the above FDA approved topical products except transdermal patches, (1) there is no possible way to take the exact dose needed for the topical treatment from the product container; (2) There is no possible way to transfer or apply all the topical product from your hand to skin, there is always inconsistent amount of drug will be sticking to you hand and it will be washed away; (3) When you put on clothes, it gets solid and it takes away part of the topical product. All the above factors create the underdose or overdose with current marketed topical products.
[0128] The topical solutions, which has the drug in dissolved state can act rapidly and can penetrate the skin faster, but it can't be hold on to the skin to the treatment, so most of the currently existing topical formulations in the market (ointment, cream, gel, etc. are made up by adding ingredients to make it viscous and thick in consistency and ability to stick to the skin surface, so that the products need to be rubbed on to the skin, whereby the ingredients will melt and by its viscous nature it will hold the drug on to the skin till it penetrates the skin for treatment. Hence longer onset for its activity.
[0129] The current topical products when applied to the skin and there is no mechanism to hold on the skin for longer period, so it is applied 3 to 4 times a day for local treatment, hence there are not many topical products (ointments, creams and gels) that can be applied on the skin to treat the drug for systemic circulation for which the drug will release into the Epidermis and needs to go to the blood vessel for systemic circulation.
[0130] Transdermal patches can be applied for both local and for systemic circulation that will be held on the skin for longer periods like EXELON PATCH (rivastigmine transdermal system) Apply patch on intact skin for a 24-hour period; replace with a new patch every 24 hours.
[0131] Surprisingly, we have found a novel way to provide a topical product that incorporates both hands free approach for the application and much more efficacy with rapid onset of action at ready to act format for local and systemic treatment. Fast acting: The invention uses readily dissolved version of the drug in solution with penetration enhancers, that can act rapidly for the treatment and provides faster onset of action.
[0132] Exact dose: with the airless container metered dose, exact dose can be applied each time through a metered dose system. During application, when it is pumped the exact dose required for treatment.
[0133] Hands Free application: When the airless container is pumped, the drug solution is delivered into the applicator, and the drug product can be applied from the applicator to the treatment area without using the hand and will not leave any residue or greasiness d) Patient compliance: With Appod all the three doses required for treatment per day can be added all at once in the Appod, it spreads and continuously delivers for one day treatment without administering 3 times and cloths can we worn Appod protect the treatment area and cloths/beds will not get soiled.
[0134] It is an object to provide a handheld THADS system that includes a topical applicator for dispensing a precise amount of liquid or exact dose and can be applied hands free application on a particular surface such as a skin of a human or animal. It is an object to provide a THADS system that can provide a ready to act product that may act fast compared to conventional ointment, creams and transdermal patches for a single vertical press of the airless container.
[0135] It is an object to provide a THADS system that can provide a fast acting and administer a topical does once a day application compared to conventional ointment, creams for a single vertical press of airless container and the products pumps into the Appod It is an object to provide a topical applicator with a housing and grip that is ergonomic and help hands free application of a topical product.
[0136] It is an object to provide a topical applicator with a liquid delivery system that releases a sufficient amount of liquid upon application onto a surface without producing any blotches or mess.
[0137] It is an object to provide a THADS system that can provide a, efficacious, multimodal topical method of treatment and prevent soiling of cloths and bed and provide effective dose for treatment effectively.
[0138] The following marketed topical products, Aspercreme no mess liquid, Icy Hot no mess applicator, Voltaren Emulgel with no mess applicator and Aleve X roller ball applicator are the topical applicators, these commercial ones are integrated with the container and are pull/push or roll-on mechanism. Roll-on applicators are in common use today. They comprise a container for the liquid and a nozzle having a ball seat and a ball rotatably supported on said seat. To apply the liquid to a selected surface, all that need be done is to invert the container so that its nozzle faces downwardly and said container is then moved across said surface with its ball in rolling contact therewith. The ball becomes coated with the liquid contents of the container and it in turn then coats the selected surface. the container is specially made to receive the nozzle and in some cases the container and nozzle are integral with each other and all these technology does not provide the exact dose or metered dose of drug and the applicator is not flexible to apply difficult to reach parts of the body.

It serves as a barrier between pressure sensitive adhesive 26 and hold or acts as pod for the readily active drug products such as solution, suspension, emulsion foam etc. or a pod like silicone pod that holds the ready to act solution or sustained acting solution or suspension, The outer polymer fabric layer 19 also protects the treatment site from contamination during the treatment period, has high moisture vapor transmission rate to allow the skin to perspire, protects the content from water while taking bath.
[0337] The outer polymer fabric layer 19 of Appod is thin, highly flexible, or deformable, water-impervious, or water pervious or substantially impervious to external fluids, yet breathable. In some embodiments, in some embodiments a second or multiple polymeric fabric layer can be adhered or blended to the outer polymer fabric layer 19 and these layers are water-impervious, or substantially impervious to external fluids. In general, the thickness of outer polymer fabric layer 19 is between about 15 to about 300 microns (um), preferably between about 80 to about 200 um and most preferably, about 150 um to achieve the forming and flexing characteristics desired.
[0338] In some embodiments, the polymeric materials used in outer polymer fabric layer 19 are conformable to the contours of the body, and flexible so as to permit free movement of the body part wearing an Appod outer polymer fabric layer 19 is very lightweight, and may be elastic (elastomeric) in character. It can be a woven or nonwoven fabric, a film, or a foam. Preferred polymeric materials useful in forming the wound cover 20 could include polyolefin (such as polyethylene), polyurethane, and polyvinylchloride. Other examples of backings include, but are not limited to, nonwoven, woven, or knitted fabrics such as cotton, polyester, polyurethane, rayon, and the like.
[0339] A polyethylene film may be used as outer polymer fabric layer 19. However, particularly effective results can be achieved with stretchable, elastomeric films formed of polyurethane, which has the further advantage of gas (including water vapor) transmissibility. In addition, outer polymer fabric layer 19 may be made from other polyolefins, vinyl polyethylene acetate, textile non-woven fabrics, rubber, tissue paper, plastic netting, adsorbent pads, or other materials known in the adhesive article art.
[0340] In some embodiments, outer polymer fabric layer 19 is substantially transparent.
[0341] The Appod may be particularly desirable to protect small wounds, such as non-bleeding cuts and the like, without visible bandages. In other embodiments, outer polymer fabric layer 19 is substantially translucent. In still other embodiments, outer polymer fabric layer 19 is substantially opaque. An opaque outer polymer fabric layer 19 can serve to hide the wound from view. In other embodiments, such as for use in children's wound Appod the outer polymer fabric layer 19 may be decorated. Decorations include color or colors, decals, printed messages, or cartoons. The decoration serves the dual purpose of hiding the wound site from view, as well as providing entertainment for the wearer of the Appod.
[0342] Again, outer polymer fabric layer 19 has disposed thereon a pressure sensitive adhesive 26 arranged and configured to adhere to mammalian skin during use. Adhesive 26 comprises at least one colloidal absorbent component dispersed therein. The colloidal absorbent component used may be any substance that has a good performance in this utilization. Preferred colloidal absorbent components include hydrocolloids, such as, sodium carboxymethylcellulose, pectin, xanthan gum, polysaccharides, sodium or calcium alginates, chitosan, seaweed extract (carrageenan), polyaspartic acid, polyglutamic acid, hyaluronic acid or salts and derivatives thereof, among others. polyesters, polyethylenes, polypropylenes, polystyrenes, polyvinylchloride, and a polyethylene terephthalate/ethylene vinyl acetate laminate.
[0343] Hydrocolloids, such as sodium carboxymethylcellulose and pectin, among others, are agents that form gels as soon as they come into contact with the bodily fluids from the wound. When used in adhesive bandages, these hydrocolloids are combined with elastomers and/or adhesives. Preferably, the wound cover provides a humid environment but without saturation, cicatrisation, which is a situation suitable for acceleration of the healing.
[0344] In some embodiment the content of the pressure-sensitive adhesive in Appod is preferably 5 to 30%% by mass, for example, based on the total mass of the adhesive layer, more preferably 10 to 20% by mass, and further preferably 5 to 15% by mass.
[0345] The adhesive substance used in the flexible substrate of the present invention may, for example, be any suitable adhesive substance. Preferably, the adhesive substance is a medical grade adhesive, such as acrylic based pressure sensitive adhesives (PSAs), rubber based pressure sensitive adhesives, silicone pressure sensitive adhesives, mixtures thereof, or the like. Examples of polymeric rubber bases include one or more of styrene-isoprene-styrene polymers, styrene-olefin-styrene polymers including styrene-ethylene/propylene-styrene polymers, polyisobutylene, styrene-butadiene-styrene polymers, polyisoprene, polybutadiene, natural rubber, silicone rubber, acrylonitrile rubber, nitrile rubber, polyurethane rubber, polyisobutylene rubber, butyl rubber, halobutyl rubber including bromobutyl rubber, butadiene-acrylonitrile rubber, polychloroprene, and styrene-butadiene rubber.

[0360] Data from Table 6 that used the following dissolution method to test the THADS Lidocaine in Appod versus the marketed Icy Hot Patches in 5 minutes by testing dissolution using USP Apparatus 5 (paddle over disk method), with purified water as the medium volume, 200 mL per vessel. The temperature is maintained at 320.5 C. a distance of 252 mm between the paddle blade and the surface of the disk assembly. The rotation speed was set at 50 rpm. THADS Lidocaine in Appod had released 85% of drug in 5 minutes interval than the 6.3% of the marketed Icy Hot Patches, this show the THADS Appod has rapid onset. The lower dissolution rate of the marketed product is due to the drug added with the adhesive in the patches, that hold the drug from releasing faster.
[0361] All the marketed transdermal products Transdermal Scop, Secuado, Butrans, Catapres-TTS, Estraderm, Climara, Vivelle, Duragesic, Sancuso, Daytrana, Nitrodur, Minitran, Oxytrol, Excelon, Neupro, Emsam, Androderm, Nioderm, Zecuity, Qutenza, Flextor, Lidoderm, Salonpas, Aspercreme, Biofreeze, Icy Hot patches all has the drug mixed with adhesive and adhesives covers the entire patches size that is adhering to the skin.
[0362] THADS system is very effective for when used stand-alone using the sponge applicator and the Appod and it will provide a rapid onset of action.
b) High Efficacy of THADS System
[0363]
c) Low Dose and High Efficacy:
[0364] The Over-the-counter topical pain marketed product Salonpas a lidocaine 4% patch contains 560 mg of drug/patch (10), directions indicate apply to affected area not more than 3 to 4 times daily (i.e., per day it requires 1680 mg to 2240 mg of lidocaine drug) and Aspercreme another marketed pain reliever path includes lidocaine 4% patch contains 246 mg/patch, Directions indicate apply to affected are not more than 3 to 4 times daily. i.e. per day it requires 738 mg to 984 mg of lidocaine, compared to 240 mg of lidocaine using THADS solution and THADS Appod, it shows the improved and enhanced efficacy of the THADS system.
d) Patient Compliance: Adhesion Issues with the Marketed Transdermal Patches
[0365] A commonly reported issue with topical patch products including the 5% lidocaine hydrogel patch is adhesion. FDA Adverse Events Reporting System found that for the lidocaine patch (Lidoderm), about 70% of concerns reported regarded poor product adhesion.

e) Effect of Cold Conditions on Topical Products:
[0368] The currently marketed topical products (Table 2) like ointment and creams uses a vehicle or base to hold the drug and when rubbed at the skin it will melt and leave the drug for the treatment, but when exposed to cold conditions the vehicle becomes hard and thick in consistency and may not release the drug in cold conditions. This was demonstrated below using the marketed topical temporary pain relief products of various formulation like creams, ointments. When the creams and ointment were at upright position at room temperature in a bottle as shown in
[0369] When the marketed products of creams and ointment stored at refrigerated conditions for 2 hours and inverted, there is no movement of the products to its bottom, the creams and ointments became thicker and more viscous during cold conditions, this shows that these products may not work in cold conditions, during winter states like Minnesota, Michigan, Illinois, New York, and other Northern states gets colder and typical topical product may not work effectively. Whereas the THADS Lidocaine PD-IID-23 on the right corner in
[0370] The invention is very much required to relieve pain in cold regions of Minnesota, New York, New Jersey, and Northeastern States. The THADS ready to act will work in the same pattern in hot, warm, and cold conditions with is very unique to the marketed topical products.

Example 3
[0377] The application of transdermal patches is not free from disadvantages. In fact, irritant contact dermatitis (ICD) provoked by the adhesive, the active principle or the excipients may often appear, and also allergic contact dermatitis (ACD), consequent to sensitization to the administered active principles (7).
[0378] The side effects of the application of the transdermal system are primarily dues to 1) API irritation, some of the drug included in the transdermal system can cause irritation. 2) Transdermal system composed of occlusive backing polymer, which will not allow the system to breathe and also the formulation does not water in it, so it causes the dryness of the skin and causes the skin irritation 3) the adhesive in the transdermal system, most transdermal patches the adhesives are mixed with the drug in a form of matrix, the adhesive from the patches causes the irritation.
[0379] The primary component that causes the skin irritation is from the adhesives.

[0388] Current treatment of shingles requires minimum of three drugs i.e., Antiviral, Analgesic & Anti-inflammatory and continuous local anesthetic administered simultaneously to treat shingles.
[0389] Shingles is impossible to treat shingles as a topical treatment with current FDA approved drugs products:
[0390] Option #1: If Acyclovir is applied as topical ointment or cream, it is impossible to apply diclofenac gel or the lidocaine topical cream on top of the acyclovir ointment, so this option is not possible, if acyclovir ointment is applied as topical product, diclofenac can be taken orally, but lidocaine can't be taken topically to relieve from itchiness.
[0391] Option #2: If Diclofenac topical solution is applied then it is impossible apply Acyclovir ointment and Lidocaine cream or ointment on top of the Diclofenac topical product.
[0392] Option #3: If Lidocaine topical cream or the transdermal patches can be applied and the Ayclovir and diclofenac can be taken a soral tablets.
[0393] It is impossible to treat shingles with topical treatment that contains antiviral, analgesic and local anesthetic.

[0400] The THADS system makes the Singles treatment very effectively compared to the conventional treatment in which, the drug is taken orally, the drugs get absorbed systemically and high doses are required along with its side effects, compared to the doses of the drugs used in THADS system is very low. With the THADS system it is very convenient to treat the shingles at the local/topical site and with THADS appod dose adjusted is flexible and it can be once a day.
[0401] THADS system is an example of method of treatment that acts locally to cure the shingles rather than conventional uses of systemic drugs, low dose of drugs will be used as it uses local topical approach and due to rapid onset of action, this system is very conveniently used for multimodal drug approach and with use of Appod the cloths and bed will not get soiled and this provides high patient compliance.
[0402] According to the present invention, a pharmaceutical product and the treatment of topical disease for local treatment or for systemic treatment. More specifically, a pharmaceutical solution, appod a THADS system for the prevention and/or treatment of various topical disease and drug intended for systemic administration can administered hand free, fast onset of action, provide exact dose, highly efficacious and high patient compliance.
[0403] The efficiency of transdermal drug delivery systems using patches depends often on the rate of absorption of water from the skin and dissolve the active drug from the transdermal matrix and diffusion rate of the active substance through the skin, which on one hand depends on the active substance and its solubility and the water from the skin and dissolving the drug on the other hand the amount of water from the skin entering into the matrix and dissolve the drug varies from human being to human being, and also from the body area the patch is applied to. The constructions of the patches known from prior art usually try to control these dependencies, but the efficiency is not achieved.
[0404] It is an object of the present invention to provide a topical delivery system for an which avoids the draw backs known from the prior art. It is a further object of the present invention to provide a THADS technology which is able to administrate the topical drug delivery hands free and delivery drugs, very efficaciously with high patient compliance to a subject over a period of time in a consistent and controllable way.
