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 ...
Characterization and evaluation of solid self-microemulsifying drug delivery systems with porous carriers as systems for improved carbamazepine release
(Elsevier Science BV, Amsterdam, 2012)
The purpose of this study was to investigate solid self-microemulsifying drug delivery system (SSMEDDS), as potential delivery system for poorly water soluble drug carbamazepine (CBZ). Self-microemulsifying drug delivery ...
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 ...
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 ...
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 ...
Solubility enhancement of desloratadine by solid dispersion in poloxamers
(Elsevier Science BV, Amsterdam, 2012)
The present study investigates the possibility of using poloxamers as solubility and dissolution rate enhancing agents of the poorly water soluble drug substance desloratadine that can be used for the preparation of immediate ...
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 ...
An investigation into the usefulness of different empirical modeling techniques for better control of spray-on fluidized bed melt granulation
(Elsevier Science BV, Amsterdam, 2015)
Melt granulation in fluid bed processors is an emerging technique, but literature data regarding the modeling of this granulation method are lacking. In the present study different techniques (response surface analysis, ...
Investigation of surfactant/cosurfactant synergism impact on ibuprofen solubilization capacity and drug release characteristics of nonionic microemulsions
(Elsevier Science BV, Amsterdam, 2012)
The current study investigates the performances of the multicomponent mixtures of nonionic surfactants regarding the microemulsion stabilisation, drug solubilization and in vitro drug release kinetic. The primary surfactant ...
An investigation into the effect of formulation variables and process parameters on characteristics of granules obtained by in situ fluidized hot melt granulation
(Elsevier Science BV, Amsterdam, 2012)
The aim of this study was to investigate the influence of binder content, binder particle size, granulation time and inlet air flow rate on granule size and size distribution, granule shape and flowability, as well as on ...
