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 ...
Optimization of matrix tablets controlled drug release using Elman dynamic neural networks and decision trees
(Elsevier Science BV, Amsterdam, 2012)
The main objective of the study was to develop artificial intelligence methods for optimization of drug release from matrix tablets regardless of the matrix type. Static and dynamic artificial neural networks of the same ...
Paracetamol extended release FDM 3D printlets: Evaluation of formulation variables on printability and drug release
(International Journal of Pharmaceutics, 2021)
Paracetamol printlets were prepared via hot-melt extrusion process and fused deposition modelling, using two types of backbone polymers. Polycaprolactone (PCL) and Polyethylene oxides (PEO) 100 K and 200 K were used, while ...
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 ...
Modified local diatomite as potential functional drug carrier-A model study for diclofenac sodium
(Elsevier Science BV, Amsterdam, 2015)
Diatomite makes a promising candidate for a drug carrier because of its high porosity, large surface area, modifiable surface chemistry and biocompatibility. Herein, refined diatomite from Kolubara coal basin, which complied ...
Curcumin-loaded low-energy nanoemulsions as a prototype of multifunctional vehicles for different administration routes: Physicochemical and in vitro peculiarities important for dermal application
(Elsevier Science BV, Amsterdam, 2018)
The objective of this work was to investigate and profoundly characterize low-energy nanoemulsions as multifunctional carriers, with slight reference to dermal administration. An evidence-based approach was offered for ...
Optimization of formulation and process parameters for the production of carvedilol nanosuspension by wet media milling
(Elsevier Science BV, Amsterdam, 2018)
The aim of this study is to develop nanosuspension of carvedilol (CRV) by wet media milling. Concentration of polymeric stabilizer (hydroxypropyl cellulose-HPC-SL), milling speed and size of milling beads were identified ...
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 ...
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 ...
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 ...
