The physicochemical characterization and in vitro/in vivo evaluation of natural surfactants-based emulsions as vehicles for diclofenac diethylamine.
Drug development and industrial pharmacy, 2007Co-Authors: Nada Vučinić-milanković, Snežana Savić, Gordana Vuleta, Slavica VučinićAbstract:Two sugar-based emulsifiers, cetearyl alcohol & cetearyl glycoside and Sorbitan Stearate & sucrose cocoate, known as potential promoters of lamellar liquid crystals/gel phases, were investigated in order to formulate an optimal vehicle for amphiphilic drug - diclofenac diethylamine (DDA). Physico-chemical characterization and study of vehicle's physical stability were performed. Then, the in vitro DDA liberation profile, dependent on the mode of drug incorporation to the system, and the in vivo, short-term effects of chosen samples on skin parameters were examined. Droplets size distribution and rheological behavior indicated satisfying physical stability of both types of vehicles. Unexpectedly, the manner of DDA incorporation to the system had no significant influence on DDA release. In vivo study pointed to emulsion's favorable potential for skin hydration and barrier improvement, particularly in cetearyl glycoside-based vehicle.

natural surfactant based emulsion vehicles a correlation between colloidal structure and in vitro release of diclofenac diethylamine
Journal of Dispersion Science and Technology, 2010Co-Authors: Nada Vucinicmilankovic, Snežana Savić, Gordana Vuleta, Slavica VucinicAbstract:The need for an official pharmaceutical vehicle or carrier of drug based on natural sugar emulsifiers that protect and regenerate natural barriers of the skin lipid layer is constantly increasing. This article studies the specific structures of emulsions and two manners of water binding that provide prolonged skin moisturization and delayed or prolonged release of drugs insoluble in water. Natural emulsifiers of an alkylpolyglucoside (cetearyl alcohol and cetearyl glycoside) and estar-type (Sorbitan Stearate and sucrose cocoate) are used for manufacturing vehicle/carriers of drugs (diclofenac diethylamine). Specific hydrofilic groups in emulsifiers, such as glycozide and ester, are capable of binding in different manners and variable quantities of water by hydrogen bonds within the cream, which is responsible for water distribution and prolonged skin moisturization. This lyotropic potential of natural emulsifiers—alkylpolyglucoside and estar type—may affect the physical stability of topical vehicles by de...

influence of trehalose on the interaction of curcumin with surface active ionic liquid micelle and its vesicular aggregate composed of a non ionic surfactant Sorbitan Stearate
Chemical Physics Letters, 2016Co-Authors: Arpita Roy, Rupam Dutta, Nilmoni SarkarAbstract:Abstract The present investigation unravels the effect of trehalose on 1-hexadecyl-3-methylimidazolium chloride ([C16mim]Cl), a cationic surface active ionic liquid (SAIL) micelle and SAIL ([C16mim]Cl)-nonionic surfactant (Sorbitan Stearate, Span 60) based vesicles. The influence of trehalose on size and morphology of the aggregates has been investigated using dynamic light scattering (DLS) and transmission electron microscopic (TEM) measurements. Besides, we have studied the dynamic properties of curcumin inside these aggregates using fluorescence spectroscopic based techniques. The results revealed that trehalose molecules play crucial role in modulation of the photophysical properties of curcumin in these organized assemblies.
