Approximately ⅓ of persons having a psoriasis condition suffer from head or scalp psoriasis. Often, it is not detected because it is not visible underneath the hair of the person who is suffering with psoriasis. Sometimes, head or scalp psoriasis is confused with dandruff or other head or scalp conditions that are sometimes deemed to be treatable with ordinary shampoos and conditions.
There exist treatments for psoriatic and eczematic scalp conditions which are steroid-based. Steroid-based treatments are sometimes effective, but can also sometimes have serious negative short-term or long-term side effects. Clobex shampoo (0.05%), by Galderma Labs USA, is an example of a steroid, specifically a corticosteroid, based shampoo that was approved by FDA for treatment of scalp psoriasis. CLOBEX® (clobetasol propionate) Shampoo, 0.05%, contains clobetasol propionate, a synthetic fluorinated corticosteroid, for topical dermatologic use. The corticosteroids constitute a class of primarily synthetic steroids used topically as anti-inflammatory and antipruritic agents.

Psoriasis is a common T-cell-mediated immune disorder characterized by circumscribed, red, thickened plaques with an overlying silver-white scale. Psoriasis is regarded as an autoimmune disease in which genetic and environmental factors have a significant role. The name of the disease is derived from Greek word ‘psora’ which means itch. Psoriasis is a non-contagious, dry, inflammatory and ugly skin disorder, which can involve entire system of person. It is mostly inherited and mainly characterized by sharply marginated scaly, erythematous plaques that develop in a relatively symmetrical distribution. The most commonly affected sites are the scalp, tips of fingers and toes, palms, soles, umbilicus, gluteus, under the breasts and genitals, elbows, knees, shins and sacrum.
Gel as semisolid, being either suspensions of small inorganic particles or large organic molecules interpenetrated with liquid. A gel is a semisolid system of at least two interpenetrating phases: a gelling agent and a liquid. Gels that contain water are called hydrogels, while those that contain an organic liquid are called organogels. Hydrogels, in the broad sense, include the matrix of water−soluble materials such as cellulose derivatives and natural gums.

Conclusion
In the present work, drug 3HX loaded nanogel was developed by employing Carbopol Ultraze 21 as a gelling agent. Different penetration enhancers such as propylene glycol, polyethylene glycol and menthol were used to enhance the permeation of the drug from the nanogel. Varying the concentration of the penetration enhancer, three different formulations were prepared. The formulations were also evaluated for Color & appearance, Homogeneity, Phase Separation, Grittiness, pH and % drug content. All three formulations (F1, F2 and F3) were evaluated for in vitro release study which was carried out for 24 h. Among all the three formulations, F3 showed the highest % cumulative drug release of 84.23%. Therefore, for the further evaluation formulation F3 was selected. The amount of the drug released was incorporated into various release kinetic models. The observed best fit model was Higuchi model followed by First order release model with R2 0. 0.9827 and 0.9666 respectively. Skin permeation study was carried out for the example formulation F3 with 79.94±2.88% of cumulative amount of drug permeated.

A step in an example process may include taking about one part of root and rhizome of DH, one part of flowers of JYH, and three parts of root of SDH and grind in a mixer grinder for 3-5 minutes until it appears to be a fine powder. After grinding, it may look like coarse or fine powder. One part of da huang, one part of jin yin hua and three parts of sheng di huang may be mixed together in an example process, while the sheng di huang may be added separately with a cooked mixture of da huang and jin yin hua. Water may be added to herb mixture in a ratio of 20 ml water per gram of herbs initially at room temperature and raised up to boiling temperature and turned down to cook at 70° C. in one example. In one example, one liter of extract preparation may take a minimum of 5 min+3 min to boil. One liter of extract at lab scale may take 2 hours, 2.5 hours or 3 hours in different examples. After boiling, the mixture may be cooked at 70° C. for 30-40 minutes. Other steps may include, for one liter extract preparation (Lab scale): soaking time: 15 minutes (10 minutes-1 hour); boiling time: 5-8 minutes (3 minutes to 15 minutes); Cooling to 70° C.:10-15 minutes (5 minutes to 1 hour); and/or cooking at 70° C.:30-40 minutes (5 minutes to 1 hour). The mixture may be strained with the help of a 100 mesh or fine mesh filter. Nano-particulate sizes between 100 nm and 300 nm are used in certain embodiments.
Nano-sized delivery systems may be selected for drug delivery because of one or more of the following reasons:
See, e.g., Nanotechnology-based drug delivery systems and herbal medicines: a review. Bonifacio B V et al., International Journal of Nanomedicine 2014:9 1-15, which is incorporated by reference.
Novel drug delivery systems in general help to target into the tissues through skin layers and can provide better therapy for topical treatment of psoriasis. Stratum corneum (SC) is the major challenge for the drug to get into the target tissues, via skin layers. Penetration enhancers added in the drug carriers help to increase the penetration capacity of drug through the outermost layer of the skin. Specific permeation studies on nano-3HX through different layers of the skin will tell us more.
For the preparation of one liter extract (on lab scale), centrifuge the extract for 30 minutes at 4000 rpm, and collect the supernatant.
An example tablet or capsule may include lactose monohydrate. In place of lactose monohydrate microcrystalline cellulose, and/or spray dried lactose, and/or Avicel may be used. In place of polyvinyl povidone k-30 or PVP K-30, PVP K-15 or HPMC can be used. Magnesium stearate and talc may be used as glidants and/or in place of talc, colloidal silicon dioxide can be used. The bioavailability enhancers piperine (0.5-10% w/w), (fulvic acid: 0.5-50% w/w) and/or inulin (1-30%) may be included in an example tablet or capsule and/or lysergol (2-2.5%) may be included as a bioavailability enhancer.
A lipid-based formulation may be made up of solid lipid, emulsifier and water/solvent. The lipids used may be triglycerides (tri-stearin), partial glycerides (Imwitor), fatty acids (stearic acid, palmitic acid), and steroids (cholesterol) and waxes (cetyl palmitate). Various emulsifiers and their combination (Pluronic F 68, F 127) have been used to stabilize the lipid dispersion. The combination of emulsifiers might prevent particle agglomeration more efficiently.
Excipients for preparing an example oral lipid-based formulation may include dietary oils composed of medium (coconut or palm seed oil) or long-chain triglycerides (corn, olive, peanut, rapeseed, sesame, or soybean oils, including hydrogenated soybean or vegetable oils), lipid soluble solvents (polyethylene glycol 400, ethanol, propylene glycol, glycerin), and various pharmaceutically-acceptable surfactants (Cremophor® EL, RH40 or RH60; polysorbate 20 or 80; D-α-tocopherol polyethylene glycol 1000 succinate (TPGS®); Span 20; various Labrafils®, Labrasol®, and Gelucires®). These formulations, which took the form of either bulk oral solutions or liquid-filled hard or soft gelatin capsules, were applied in instances where conventional approaches (solid wet or dry granulation, or water-miscible solution in a capsule) did not provide sufficient bioavailability, or in instances in which the drug substance itself was an oil (dronabinol, ethyl icosapentate, indometacin farnesil, teprenone, and tocopherol nicotinate). The total daily drug dose administered in these formulations, which may range in complexity from simple solutions of the drug in a dietary oil up to multi-excipient, self-emulsifying drug delivery systems (SEDDS), may range from less than 0.25 μg to greater than 2000 mg. The amount of drug contained in a unit-dose capsule product may range from 0.25 μg to 500 mg and for oral solution products, from 1 μg/ml to 100 mg/ml. The total amount of lipid excipient administered in a single dose of a capsule formulation may range from 0.5 to 5 g, and can range from as low as 0.1 ml to as high as 20 ml for oral solution products. Some of these products tolerate room temperature storage for only brief periods of time and require long-term storage at 2-8° due to chemical and/or physical stability issues.
