The decrease in entrapment can be attributed to the expulsion of drug on solid lipid crystallization which is significantly higher in case of sln [9 müller rh, radtke m, wissing sa, et al solid lipid nanoparticles (sln) and nanostructured lipid carriers (nlc) in cosmetic and dermatological preparations. Psoriasis is a chronic immune-mediated skin disease characterized by keratinocyte hyperproliferation and increased dermal vascularity, which affects ~ 2 -- 3% of the world population . Psoriasis is a chronic, autoimmune disease affecting as many as 75 million americans and 2% to 3% of the world population (data from national psoriasis foundation website) the most prevalent form of psoriasis, plaque psoriasis, is recognized by psoriatic plaques of red lesions covered by silvery white flakes on top of the skin.

Methotrexateloaded solid lipid nanoparticles for topical treatment of psoriasis: formulation & clinical implications | articles | drug development and delivery back issues | drug development & delivery issue: vol 4 no 8 october 2004, posted date: 3/27/2008 methotrexateloaded solid lipid nanoparticles for topical treatment of.
Solid lipid nanoparticles and liposomes offer potential value as topical drug delivery systems in addition to polymeric and metal-based nanoparticles electrospun nanofibers have also shown great promise in the area of wound healing and as antimicrobial dressings. Initially, sln was prepared by solvent injection method by using clobetasol (drug), carnauba wax and beeswax as lipid phase, cetyl alcohol and lecithin soya as surfactants tween 20 as co surfactant phase and finally distilled water to make up the volume where in this method, both liquid phase and lipid phase were heated to 70-75oc. Conclusions clobetasol propionate ointment bd for 2 weeks followed by treatment with calcipotriol ointment bd for 4 weeks was superior to calcipotriol ointment alone in the treatment of plaque psoriasis.
To this end, liposomes , lipid nanoparticles , and polymeric nanoparticles [31,32] have been proposed as potential drug carrier systems that could improve the retention of encapsulated corticosteroids within the skin, such as demonstrated in solid lipid nanoparticles [30,33. Solid lipid nanoparticles (slns) are the new generation of oil-in-water nanoparticulate systems and are attracting attention as novel colloidal drug carriers for topical use. Solid lipid nanoparticles (sln) are a colloidal carrier system for controlled drug delivery and followed by the development of emulsion, liposomes, microparticles and nanoparticles based on synthetic polymers since the beginning of the nineties (müller et al, 2000. Solid lipid nanoparticles (slns) are the new generation of submicron sized lipid emulsions where liquid lipid (oil) has been substituted by solid lipid lipids used in the formulation are safe, stable and biodegradable in nature slns offer various advantages for topical drug delivery like ability. Clobetasol propionate followed by calcipotriol is superior to calcipotriol alone in topical treatment of psoriasis the superiority of the clobetasol propionate followed by calcipotriol treatment was maintained during a 4-week, treatment-free, observation period sameer s katiyar, varun kushwah, sanyog jain, solid lipid nanoparticles.
(indian journal of experimental biology, vol 43 march 2005,pp 233-240)-in the present study clobetasol propionate (cp) was loaded as solid lipid nanoparticles (sln), incorporated it in suitable cream base and evaluated in vitro and its performance clinically against equivalent marketed formulation. Solid lipid nanoparticles (sln) are the new generation of nanoparticulate active-substance vehicles and are attracting major attention as novel colloidal drug carriers for topical use slns are in the submicron size range and they are composed of physiologically tolerated lipid components which at room temperature remain in the solid state. On considering various lipid-based carrier systems, solid lipid nanoparticles (sln) and nanostructured lipid carriers (nlc) are considered to be the most suitable ones [8 souto e, doktorovova s, boonme p, et al lipid-based colloidal systems (nanoparticles, microemulsions) for drug delivery to the skin: materials and end-product formulations.
Kalariya, m padhi, bk chougule, m misra, a clobetasol propionate solid lipid nanoparticles cream for effective treatment of eczema: formulation and clinical implications indian j exp biol , v43, n3, p233-240, 2005. Solid-lipid nanoparticles (slns) are submicron colloidal carriers composed of a single lipid core matrix that is solid at body temperature, and is coated with a surfactant acting as stabilizer [43–45] these structures are more stable than liposomes or emulsions.
In the present study clobetasol propionate (cp) was loaded as solid lipid nanoparticles (sln), incorporated it in suit able cream base and evaluated in virro and its performance clinically against equi valent marketed formulation.
