17 beta-carboxamide steroids - in vitro prediction of human skin permeability and retention using PAMPA technique
(Elsevier Science BV, Amsterdam, 2014)
In this paper, twenty-two 17 beta-carboxamide steroids were synthesized from five corticosteroids (hydrocortisone, prednisolone, methylprednisolone, dexamethasone and betamethasone) in two steps. The first step was periodic ...
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 ...
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 ...
Formulation of hydrogel-thickened nonionic microemulsions with enhanced percutaneous delivery of ibuprofen assessed in vivo in rats
(Elsevier Science BV, Amsterdam, 2016)
The study investigated usage of hydrogel of an anionic polymer xanthan gum for design of ibuprofen-loaded hydrogel-thickened microemulsions (HTMs) from the nonionic oil-in-water microemulsion (M). Xanthan gum demonstrated ...
Development of solid lipid microparticles by melt-emulsification/spray-drying processes as carriers for pulmonary drug delivery
(Elsevier B.V., 2021)
The aim of this study was to optimize the parameters of the complex melt-emulsification process coupled with the spray-drying, in order to maintain the balance between solid lipid microparticles (SLMs) powders aerodynamic ...
Tableting of hot-melt coated paracetamol granules: Material tableting properties and quality characteristics of the obtained tablets
(Elsevier B.V., 2020)
Hot-melt coating (HMC) has been recognized as a promising technique in the production of solid dosage forms e.g., HMC of granules can be applied prior to compression in order to obtain modified drug release or taste masking. ...
Synthesis of the vitamin E amino acid esters with an enhanced anticancer activity and in silico screening for new antineoplastic drugs
(Elsevier Science BV, Amsterdam, 2016)
Tocopherols and tocotrienols belong to the family of vitamin E (VE) with the well-known antioxidant properties. For certain alpha-tocopherol and gamma-tocotrienol derivatives used as the lead compounds in this study, ...
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, ...
Sucrose esters as biocompatible surfactants for penetration enhancement: An insight into the mechanism of penetration enhancement studied using stratum corneum model lipids and Langmuir monolayers
(Elsevier Science BV, Amsterdam, 2017)
Up to now, the molecular mechanism of the penetration enhancing effect of sucrose esters (SEs) on stratum corneum (SC) has not been explained in details. In this study, variety of surface sensitive techniques, including ...
