Dry powder inhalers: An overview of the in vitro dissolution methodologies and their correlation with the biopharmaceutical aspects of the drug products
(Elsevier Science BV, Amsterdam, 2018)
In vitro dissolution testing is routinely used in the development of pharmaceutical products. Whilst the dissolution testing methods are well established and standardized for oral dosage forms, i.e. tablets and capsules, ...
Population pharmacokinetics of topiramate in adult patients with epilepsy using nonlinear mixed effects modelling
(Elsevier Science BV, Amsterdam, 2013)
The objective of the study was to develop population pharmacokinetic model of topiramate (TPM) using nonlinear mixed effects modelling approach. Data were collected from 78 adult epileptic patients on mono- or co-therapy ...
An alkylpolyglucoside surfactant as a prospective pharmaceutical excipient for topical formulations: The influence of oil polarity on the colloidal structure and hydrocortisone in vitro/in vivo permeation
(Elsevier Science BV, Amsterdam, 2007)
There is a growing need for research into new skin- and environment-friendly surfactants. This paper focuses on a natural surfactant of an alkylpolyglucoside type, which can form both thermotropic and lyotropic liquid-crystalline ...
Drug release control and system understanding of sucrose esters matrix tablets by artificial neural networks
(Elsevier Science BV, Amsterdam, 2011)
Artificial neural networks (ANNs) were applied for system understanding and prediction of drug release properties from direct compacted matrix tablets using sucrose esters (SEs) as matrix-forming agents for controlled ...
Application of dynamic neural networks in the modeling of drug release from polyethylene oxide matrix tablets
(Elsevier Science BV, Amsterdam, 2009)
The main objective of this study was to demonstrate the possible use of dynamic neural networks to model diclofenac sodium release from polyethylene oxide hydrophilic matrix tablets. High and low molecular weight polymers ...
In vitro - in silico - in vivo drug absorption model development based on mechanistic gastrointestinal simulation and artificial neural networks: Nifedipine osmotic release tablets case study
(Elsevier Science BV, Amsterdam, 2014)
In vitro - in vivo correlations (IVIVC) are generally accepted as a valuable tool in modified release formulation development aimed at (i) quantifying the in vivo drug delivery profile and formulation related effects on ...
Semisolid self-microemulsifying drug delivery systems (SMEDDSs): Effects on pharmacokinetics of acyclovir in rats
(Elsevier Science BV, Amsterdam, 2018)
Semisolid self-microemulsifying drug delivery system (SMEDDS) with optimized drug loading capacity, stability, dispersibility in aqueous media and in vitro drug release profile, was evaluated in vivo regarding effects on ...
Analysis of fluidized bed granulation process using conventional and novel modeling techniques
(Elsevier Science BV, Amsterdam, 2011)
Various modeling techniques have been applied to analyze fluidized-bed granulation process. Influence of various input parameters (product, inlet and outlet air temperature, consumption of liquid-binder, granulation ...
The influence of drug-drug interaction and patients' characteristics on valproic acid's clearance in adults with epilepsy using nonlinear mixed effects modeling
(Elsevier Science BV, Amsterdam, 2009)
Monitoring valproic acid (VPA) concentrations is especially challenging due to its highly variable pharmacokinetics (PK) and complex interactions with other antiepileptic drugs. We used sparse routine therapeutic drug ...
Viscosity-mediated negative food effect on oral absorption of poorly-permeable drugs with an absorption window in the proximal intestine: In vitro experimental simulation and computational verification
(Elsevier Science BV, Amsterdam, 2014)
Concomitant food intake can diminish oral absorption of drugs with limited permeability and an absorption window in the proximal intestine, due to viscosity-mediated decrease in dosage form disintegration time and drug ...
