An investigation into the characteristics and drug release properties of multiple W/O/W emulsion systems containing low concentration of lipophilic polymeric emulsifier
(Elsevier Science BV, Amsterdam, 2006)
Multiple W/O/W emulsions with high content of inner phase (Phi 1 = Phi 2 = 0.8) were prepared using relatively low concentrations of lipophilic polymeric primary emulsifier, PEG 30-dipolyhydroxystearate, and diclofenac ...
Natural surfactant-based topical vehicles for two model drugs: Influence of different lipophilic excipients on in vitro/in vivo skin performance
(Elsevier Science BV, Amsterdam, 2009)
This study focuses on the properties of topical vehicles based on alkylpolyglucoside natural surfactant-mixed emulsifier, cetearyl glucoside and cetearyl alcohol, in order to propose their use as "ready to use" pharmaceutical ...
Vehicle-controlled effect of urea on normal and SLS-irritated skin
(Elsevier Science BV, Amsterdam, 2004)
It is known that, depending on the concentration, treatment with urea could improve skin barrier function, despite its penetration-enhancing properties. This controversial skin effect of urea has been explored systematically ...
The influence of cosurfactants and oils on the formation of pharmaceutical microemulsions based on PEG-8 caprylic/capric glycerides
(Elsevier Science BV, Amsterdam, 2008)
In the present study the effect of type and concentration of a cosurfactant and oil on the ability of nonionic surfactant PEG-8 caprylic/capric glycerides (Labrasol (R)) to solubilize both oil and water phases was evaluated. ...
Tablet disintegration and drug dissolution in viscous media: Paracetamol IR tablets
(Elsevier Science BV, Amsterdam, 2008)
An investigation into the influence of viscous media on tablet disintegration and drug dissolution was performed with the aim to simulate the potential formulation-specific food effect for a selected highly soluble model ...
The application of artificial neural networks in the prediction of microemulsion phase boundaries in PEG-8 caprylic/capric glycerides based systems
(Elsevier Science BV, Amsterdam, 2008)
The objective of this study was to develop artificial neural network (ANN) model suitable to predict successfully the borders of the microemulsion region in the quaternary system PEG-8 caprylic/capric glycerides (Labrasol ...
Temoporfin-loaded liposomal gels: Viscoelastic properties and in vitro skin penetration
(Elsevier Science BV, Amsterdam, 2009)
Temoporfin (mTHPC) is a potent second-generation photosensitizer. The primary object of this study was to develop a topical mTHPC-loaded liposomal hydrogel able to deliver mTHPC into the stratum corneum (SC) and deeper ...
Vehicles based on a sugar surfactant: Colloidal structure and its impact on in vitro/in vivo hydrocortisone permeation
(Elsevier Science BV, Amsterdam, 2006)
An emerging class of natural surfactants, named alkylpolyglucosides, which can form both, the thermotropic and the lyotropic, liquid crystalline phases, were focused. The aim of the study was to integrate some physicochemical ...
Characterization of caprylocaproyl macrogolglycerides based microemulsion drug delivery vehicles for an amphiphilic drug
(Elsevier Science BV, Amsterdam, 2004)
Microemulsion systems composed of water, isopropyl myristate, PEG-8 caprylic/captzc glycerides (Labrasol((R))), and polyglyceryl-6 dioleate (Plurol Oleique((R))), were investigated as potential drug delivery vehicles for ...
Role of complexes formation between drugs and penetration enhancers in transdermal delivery
(Elsevier Science BV, Amsterdam, 2008)
The use of chemical penetration enhancers (CPE) is growing due to their ability to improve drug delivery through the skin. A possible mechanism of penetration enhancement could involve the complex formation between drug ...
