In this study, clobetasol-17-propionate (CP) loaded lecithin/chitosan nanoparticles were studied with special attention to the transport of the active agent across the skin in vitro. Nanoparticles were characterized by measuring particle size, zeta potential, polydispersity index and encapsulation efficiency. The morphology of nanoparticles was evaluated by(More)
BACKGROUND Excessive generation of radical oxygen species (ROS) is a contributor to skin pathologies. Resveratrol (RSV) is a potent antioxidant. Solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) can ensure close contact and increase the amount of drug absorbed into the skin. In this study, RSV was loaded into SLN and NLC for dermal(More)
The objective of this study was to explore the potential of the nanostructured lipid carriers (NLCs) modified with chitosan oligosaccharide lactate (COL) for topical ocular application. Ofloxacin (OFX) loaded NLCs were prepared by microemulsion or high shear homogenization methods. For combination of NLCs Compritol HD5 ATO was used as solid lipid, oleic(More)
The aim of this study was to compare the effectiveness of gel formulations containing arbutin, synthetic ellagic acid and plant extracts that contain ellagic acid, on patients with melasma. Thirty patients who applied to Ege University Medical Faculty, Department of Dermatology, were included in the study. A signed consent was obtained from each patient(More)
The aim of this study was to evaluate the suitability of sodium-deoxycholate (Na-DOC) gels containing betamethasone-17-valerate (BMV) for topical application. The gels were characterized for rheological and textural properties. The in vitro flux of BMV from Na-DOC gels across rat skin was 2.5 (0.05% gel) and 8.5 times (0.1% gel) higher compared to the(More)
Stable multiple emulsions with a small proportion of primary emulsion containing different viscosifying agents in the outer aqueous phase were formulated. The multiple systems were assessed by evaluating several parameters, such as the macroscopic aspect, droplet size, release rate, and accelerated stability under elevated temperatures. The effect of(More)
This work mainly concentrates on the formulation of W/O/W multiple emulsions capable of breaking and releasing their inner aqueous phase under shear rates compatible with agroalimentary, pharmaceutical and cosmetic applications. Three kinds of multiple emulsions were studied: one with a high concentration of primary emulsion, not viscosified in the external(More)
The aim of this paper was to evaluate the effect of vehicle, chemical enhancer and iontophoresis on the skin accumulation of clobetasol propionate (CP) and mometasone furoate (MF). In vitro permeation experiments were performed using pig ear skin as barrier and HPLC as quantification method. The formulations tested were chitosan gels, sodium-deoxycholate(More)
BACKGROUND The effective delivery of coenzyme Q10 (Q10) to the skin has several benefits in therapy for different skin pathologies. However, the delivery of Q10 to deeper layers of skin is challenging due to low aqueous solubility of Q10. Liposomes and solid lipid nanoparticles (SLN) have many advantages to accomplish the requirements in topical drug(More)
Stable multiple emulsions that contain different lipophilic surfactants in the internal aqueous phase have been formulated. The multiple systems were assessed by evaluating several parameters such as macroscopic aspect, droplet size, percent release and accelerated stability under centrifugation or elevated temperature. The effect of polymeric and monomeric(More)
