n recent years there has been a growing interest in solid lipid-based systems, particularly in solid lipid microparticles (SLMs); however, only very few studies deeply investigated the dissolution behaviour of orally delivered-SLMs. The present study provides new insights about the release performance in different gastrointestinal fluids of SLMs containing a freely water soluble drug (caffeine, as BCS class I drug). Three different formulations of SLMs were prepared by spray congealing using...

Aims Food intake is known to have various effects on gastrointestinal luminal conditions in terms of transit times, hydrodynamic forces and/or luminal fluid composition and can therefore affect the dissolution behavior of solid oral dosage forms. The aim of this study was to investigate and detect the dosage form-dependent food effect that has been observed for two extended-release formulations of nifedipine using in vitro dissolution tests. Methods Two monolithic extended release formulations,...

PURPOSE: Compound solubility serves as a surrogate indicator of oral biopharmaceutical performance. Between infancy and adulthood, marked compositional changes in gastrointestinal (GI) fluids occur. This study serves to assess how developmental changes in GI fluid composition affects compound solubility. METHODS: Solubility assessments were conducted in vitro using biorelevant media reflective of age-specific pediatric cohorts (i.e., neonates and infants). Previously published adult media...

Highlights Development of a new biorelevant dissolution method for orodispersible films, considering mechanical force, saliva flow, volume and composition. Comparison of different conventional methods and the new biorelevant dissolution method regarding their consideration of in vivo conditions. Feasibility and problems of different dissolution setups for orodispersible films. Conventional dissolution setups show faster concentration onset compared to the new developed biorelevant setup. The...
